Introduction

Dockerfile to build a Redmine container image.

Version

Current Version: sameersbn/redmine:6.0.2

P.S.: If your installation depends on various third party plugins, please stick with 2.6.xx series to avoid breakage.

Contributing

If you find this image useful here's how you can help:

• Send a Pull Request with your awesome new features and bug fixes
• Help new users with Issues they may encounter
• Support the development of this image with a donation

Issues

Docker is a relatively new project and is active being developed and tested by a thriving community of developers and testers and every release of docker features many enhancements and bugfixes.

Given the nature of the development and release cycle it is very important that you have the latest version of docker installed because any issue that you encounter might have already been fixed with a newer docker release.

Install the most recent version of the Docker Engine for your platform using the official Docker releases, which can also be installed using:

wget -qO- https://get.docker.com/ | sh

Fedora and RHEL/CentOS users should try disabling selinux with setenforce 0 and check if resolves the issue. If it does than there is not much that I can help you with. You can either stick with selinux disabled (not recommended by redhat) or switch to using ubuntu.

If using the latest docker version and/or disabling selinux does not fix the issue then please file a issue request on the issues page.

In your issue report please make sure you provide the following information:

• The host distribution and release version.
• Output of the docker version command.
• Output of the docker info command.
• The docker run command you used to run the image (mask out the sensitive bits).

Installation

Automated builds of the image are available on Dockerhub and is the recommended method of installation.

Note: Builds are also available on Quay.io

docker pull sameersbn/redmine:latest

Since version 2.4.2, the image builds are being tagged. You can now pull a particular version of redmine by specifying the version number. For example,

docker pull sameersbn/redmine:6.0.2

Alternately you can build the image yourself.

docker build -t sameersbn/redmine github.com/sameersbn/docker-redmine

Quick Start

The quickest way to get started is using docker compose.

wget https://raw.githubusercontent.com/sameersbn/docker-redmine/master/docker-compose.yml
docker compose up

Alternately, you can manually launch the redmine container and the supporting postgresql container by following this two step guide.

Step 1. Launch a postgresql container

docker run --name=postgresql-redmine -d \
  --env='DB_NAME=redmine_production' \
  --env='DB_USER=redmine' --env='DB_PASS=password' \
  --volume=/srv/docker/redmine/postgresql:/var/lib/postgresql \
  sameersbn/postgresql:14-20230628

Step 2. Launch the redmine container

docker run --name=redmine -d \
  --link=postgresql-redmine:postgresql --publish=10083:80 \
  --env='REDMINE_PORT=10083' \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

NOTE: Please allow a minute or two for the Redmine application to start.

Point your browser to http://localhost:10083 and login using the default username and password:

• username: admin
• password: admin

Make sure you visit the Administration link and Load the default configuration before creating any projects.

You now have the Redmine application up and ready for testing. If you want to use this image in production the please read on.

The rest of the document will use the docker command line. You can quite simply adapt your configuration into a docker-compose.yml file if you wish to do so.

Configuration

Data Store

For the file storage we need to mount a volume at the following location.

• /home/redmine/data
• /var/log/redmine for server logs

NOTE

Existing users need to move the existing files directory inside /srv/docker/redmine/redmine/.

mkdir -p /srv/docker/redmine/redmine
mv /opt/redmine/files /srv/docker/redmine/redmine

SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.

mkdir -p /srv/docker/redmine/redmine
sudo chcon -Rt svirt_sandbox_file_t /srv/docker/redmine/redmine

Volumes can be mounted in docker by specifying the '-v' option in the docker run command.

docker run --name=redmine -it --rm \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

Database

Redmine uses a database backend to store its data.

MySQL

Internal MySQL Server

The internal mysql server has been removed from the image. Please use a linked mysql or postgresql container instead or connect with an external mysql or postgresql server.

If you have been using the internal mysql server follow these instructions to migrate to a linked mysql container:

Assuming that your mysql data is available at /srv/docker/redmine/mysql

docker run --name=mysql-redmine -d \
  --volume=/srv/docker/redmine/mysql:/var/lib/mysql \
  sameersbn/mysql:5.7.22-1

This will start a mysql container with your existing mysql data. Now login to the mysql container and create a user for the existing redmine_production database.

All you need to do now is link this mysql container to the redmine container using the --link=mysql-redmine:mysql option and provide the DB_NAME, DB_USER and DB_PASS parameters.

Refer to Linking to MySQL Container for more information.

External MySQL Server

The image can be configured to use an external MySQL database instead of starting a MySQL server internally. The database configuration should be specified using environment variables while starting the Redmine image.

Before you start the Redmine image create user and database for redmine.

mysql -uroot -p
CREATE USER 'redmine'@'%.%.%.%' IDENTIFIED BY 'password';
CREATE DATABASE IF NOT EXISTS `redmine_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
GRANT SELECT, LOCK TABLES, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `redmine_production`.* TO 'redmine'@'%.%.%.%';

We are now ready to start the redmine application.

docker run --name=redmine -it --rm \
  --env='DB_ADAPTER=mysql2' \
  --env='DB_HOST=192.168.1.100' --env='DB_NAME=redmine_production' \
  --env='DB_USER=redmine' --env='DB_PASS=password' \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

This will initialize the redmine database and after a couple of minutes your redmine instance should be ready to use.

Linking to MySQL Container

You can link this image with a mysql container for the database requirements. The alias of the mysql server container should be set to mysql while linking with the redmine image.

If a mysql container is linked, only the DB_ADAPTER, DB_HOST and DB_PORT settings are automatically retrieved using the linkage. You may still need to set other database connection parameters such as the DB_NAME, DB_USER, DB_PASS and so on.

To illustrate linking with a mysql container, we will use the sameersbn/mysql image. When using docker-mysql in production you should mount a volume for the mysql data store. Please refer the README of docker-mysql for details.

First, lets pull the mysql image from the docker index.

docker pull sameersbn/mysql:5.7.22-1

For data persistence lets create a store for the mysql and start the container.

SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.

mkdir -p /srv/docker/redmine/mysql
sudo chcon -Rt svirt_sandbox_file_t /srv/docker/redmine/mysql

The run command looks like this.

docker run --name=mysql-redmine -d \
  --env='DB_NAME=redmine_production' \
  --env='DB_USER=redmine' --env='DB_PASS=password' \
  --volume=/srv/docker/redmine/mysql:/var/lib/mysql \
  sameersbn/mysql:5.7.22-1

The above command will create a database named redmine_production and also create a user named redmine with the password password with full/remote access to the redmine_production database.

We are now ready to start the redmine application.

docker run --name=redmine -it --rm --link=mysql-redmine:mysql \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

Here the image will also automatically fetch the DB_NAME, DB_USER and DB_PASS variables from the mysql container as they are specified in the docker run command for the mysql container. This is made possible using the magic of docker links and works with the following images:

• mysql
• sameersbn/mysql
• centurylink/mysql
• orchardup/mysql

PostgreSQL

External PostgreSQL Server

The image also supports using an external PostgreSQL Server. This is also controlled via environment variables.

CREATE ROLE redmine with LOGIN CREATEDB PASSWORD 'password';
CREATE DATABASE redmine_production;
GRANT ALL PRIVILEGES ON DATABASE redmine_production to redmine;

We are now ready to start the redmine application.

docker run --name=redmine -it --rm \
  --env='DB_ADAPTER=postgresql' \
  --env='DB_HOST=192.168.1.100' --env='DB_NAME=redmine_production' \
  --env='DB_USER=redmine' --env='DB_PASS=password' \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

This will initialize the redmine database and after a couple of minutes your redmine instance should be ready to use.

Linking to PostgreSQL Container

You can link this image with a postgresql container for the database requirements. The alias of the postgresql server container should be set to postgresql while linking with the redmine image.

If a postgresql container is linked, only the DB_ADAPTER, DB_HOST and DB_PORT settings are automatically retrieved using the linkage. You may still need to set other database connection parameters such as the DB_NAME, DB_USER, DB_PASS and so on.

To illustrate linking with a postgresql container, we will use the sameersbn/postgresql image. When using postgresql image in production you should mount a volume for the postgresql data store. Please refer the README of docker-postgresql for details.

First, lets pull the postgresql image from the docker index.

docker pull sameersbn/postgresql:14-20230628

For data persistence lets create a store for the postgresql and start the container.

SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.

mkdir -p /srv/docker/redmine/postgresql
sudo chcon -Rt svirt_sandbox_file_t /srv/docker/redmine/postgresql

The run command looks like this.

docker run --name=postgresql-redmine -d \
  --env='DB_NAME=redmine_production' \
  --env='DB_USER=redmine' --env='DB_PASS=password' \
  --volume=/srv/docker/redmine/postgresql:/var/lib/postgresql \
  sameersbn/postgresql:14-20230628

The above command will create a database named redmine_production and also create a user named redmine with the password password with access to the redmine_production database.

We are now ready to start the redmine application.

docker run --name=redmine -it --rm --link=postgresql-redmine:postgresql \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

Here the image will also automatically fetch the DB_NAME, DB_USER and DB_PASS variables from the postgresql container as they are specified in the docker run command for the postgresql container. This is made possible using the magic of docker links and works with the following images:

• postgres
• sameersbn/postgresql
• orchardup/postgresql
• paintedfox/postgresql

AWS RDS Integration

docker-redmine has support for fetching secrets from AWS Secrets Manager at runtime. Read docs/aws.md for detailed instructions.

Memcached (Optional)

This image can (optionally) be configured to use a memcached server to speed up Redmine. This is particularly useful when you have a large number users.

External Memcached Server

The image can be configured to use an external memcached server. The memcached server host and port configuration should be specified using environment variables MEMCACHE_HOST and MEMCACHE_PORT like so:

Assuming that the memcached server host is 192.168.1.100

docker run --name=redmine -it --rm \
  --env='MEMCACHE_HOST=192.168.1.100' --env='MEMCACHE_PORT=11211' \
  sameersbn/redmine:6.0.2

Linking to Memcached Container

Alternately you can link this image with a memcached container. The alias of the memcached server container should be set to memcached while linking with the redmine image.

To illustrate linking with a memcached container, we will use the sameersbn/memcached image. Please refer the README of docker-memcached for details.

First, lets pull and launch the memcached image from the docker index.

docker run --name=memcached-redmine -d sameersbn/memcached:1.5.6

Now you can link memcached to the redmine image:

docker run --name=redmine -it --rm --link=memcached-redmine:memcached \
  sameersbn/redmine:6.0.2

Mail

The mail configuration should be specified using environment variables while starting the redmine image. The configuration defaults to using gmail to send emails and requires the specification of a valid username and password to login to the gmail servers.

Please refer the Available Configuration Parameters section for the list of SMTP parameters that can be specified.

docker run --name=redmine -it --rm \
  --env='SMTP_USER=USER@gmail.com' --env='SMTP_PASS=PASSWORD' \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

If you are not using google mail, then please configure the SMTP host and port using the SMTP_HOST and SMTP_PORT configuration parameters.

If you are using a google apps account with a custom domain (other than google.com), you need to set the SMTP_DOMAIN parameters or else you will get internal server error when doing an action that would normally send a mail.

Please see redmine email config for examples of different email configurations: https://www.redmine.org/projects/redmine/wiki/emailconfiguration

Similary you can configure receiving emails using the IMAP_ configuration options. Please refer Available Configuration Parameters for details. When receiving emails is enabled users can comment on issues by replying to emails.

P.S. The receiving emails feature is only available since versions 2.6.6-2, 3.0.4-2 and 3.1.0-2. Refer the Changelog for details.

SSL

Access to the redmine application can be secured using SSL so as to prevent unauthorized access. While a CA certified SSL certificate allows for verification of trust via the CA, a self signed certificates can also provide an equal level of trust verification as long as each client takes some additional steps to verify the identity of your website. I will provide instructions on achieving this towards the end of this section.

To secure your application via SSL you basically need two things:

• Private key (.key)
• SSL certificate (.crt)

When using CA certified certificates, these files are provided to you by the CA. When using self-signed certificates you need to generate these files yourself. Skip the following section if you are armed with CA certified SSL certificates.

Jump to the Using HTTPS with a load balancer section if you are using a load balancer such as hipache, haproxy or nginx.

Generation of Self Signed Certificates

Generation of self-signed SSL certificates involves a simple 3 step procedure.

STEP 1: Create the server private key

openssl genrsa -out redmine.key 2048

STEP 2: Create the certificate signing request (CSR)

openssl req -new -key redmine.key -out redmine.csr

STEP 3: Sign the certificate using the private key and CSR

openssl x509 -req -days 365 -in redmine.csr -signkey redmine.key -out redmine.crt

Congratulations! you have now generated an SSL certificate thats valid for 365 days.

Strengthening the server security

This section provides you with instructions to strengthen your server security. To achieve this we need to generate stronger DHE parameters.

openssl dhparam -out dhparam.pem 2048

Installation of the SSL Certificates

Out of the four files generated above, we need to install the redmine.key, redmine.crt and dhparam.pem files at the redmine server. The CSR file is not needed, but do make sure you safely backup the file (in case you ever need it again).

The default path that the redmine application is configured to look for the SSL certificates is at /home/redmine/data/certs, this can however be changed using the SSL_KEY_PATH, SSL_CERTIFICATE_PATH and SSL_DHPARAM_PATH configuration options.

If you remember from above, the /home/redmine/data path is the path of the data store, which means that we have to create a folder named certs inside /srv/docker/redmine/redmine/ and copy the files into it and as a measure of security we will update the permission on the redmine.key file to only be readable by the owner.

mkdir -p /srv/docker/redmine/redmine/certs
cp redmine.key /srv/docker/redmine/redmine/certs/
cp redmine.crt /srv/docker/redmine/redmine/certs/
cp dhparam.pem /srv/docker/redmine/redmine/certs/
chmod 400 /srv/docker/redmine/redmine/certs/redmine.key

Great! we are now just one step away from having our application secured.

Enabling HTTPS support

HTTPS support can be enabled by setting the REDMINE_HTTPS option to true.

docker run --name=redmine -d \
  --publish=10083:80 --publish 10445:443 \
  --env='REDMINE_PORT=10445' --env='REDMINE_HTTPS=true' \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

In this configuration, any requests made over the plain http protocol will automatically be redirected to use the https protocol. However, this is not optimal when using a load balancer.

Note: If startup prints SSL keys and certificates were not found. refer to SSL and verify you put the certs in the correct place. Unless your trying to setup for Using HTTPS with a load balancer

Configuring HSTS

HSTS if supported by the browsers makes sure that your users will only reach your server via HTTPS. When the user comes for the first time it sees a header from the server which states for how long from now this site should only be reachable via HTTPS - that's the HSTS max-age value.

With NGINX_HSTS_MAXAGE you can configure that value. The default value is 31536000 seconds. If you want to disable a already sent HSTS MAXAGE value, set it to 0.

docker run --name=redmine -d \
  --env='REDMINE_HTTPS=true' \
  --env='NGINX_HSTS_MAXAGE=2592000'
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

If you want to completely disable HSTS set NGINX_HSTS_ENABLED to false.

Using HTTPS with a load balancer

Load balancers like nginx/haproxy/hipache talk to backend applications over plain http and as such the installation of ssl keys and certificates are not required and should NOT be installed in the container. The SSL configuration has to instead be done at the load balancer. Hoewever, when using a load balancer you MUST set REDMINE_HTTPS to true.

With this in place, you should configure the load balancer to support handling of https requests. But that is out of the scope of this document. Please refer to Using SSL/HTTPS with HAProxy for information on the subject.

When using a load balancer, you probably want to make sure the load balancer performs the automatic http to https redirection. Information on this can also be found in the link above.

In summation, when using a load balancer, the docker command would look for the most part something like this:

docker run --name=redmine -d --publish=10083:80 \
  --env='REDMINE_HTTPS=true' \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

Deploy to a subdirectory (relative url root)

By default redmine expects that your application is running at the root (eg. /). This section explains how to run your application inside a directory.

Let's assume we want to deploy our application to '/redmine'. Redmine needs to know this directory to generate the appropriate routes. This can be specified using the REDMINE_RELATIVE_URL_ROOT configuration option like so:

docker run --name=redmine -d --publish=10083:80 \
  --env='REDMINE_RELATIVE_URL_ROOT=/redmine' \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2

Redmine will now be accessible at the /redmine path, e.g. http://www.example.com/redmine.

Note: The REDMINE_RELATIVE_URL_ROOT parameter should always begin with a slash and SHOULD NOT have any trailing slashes.

Apache Proxy as frontend

Ref #370

Apache config

# REDMINE Pass connections to docker
ProxyRequests Off
ProxyPass /redmine http://127.0.0.1:10083/redmine/
ProxyPassReverse /redmine http://127.0.0.1:10083/redmine/

Note the following should be set: REDMINE_RELATIVE_URL_ROOT=/redmine and port mapped --publish=10083:80

Mapping host user and group

Per default the container is configured to run redmine as user and group redmine with uid and gid 1000. The host possibly uses this ids for different purposes leading to unfavorable effects. From the host it appears as if the mounted data volumes are owned by the host's user/group 1000.

Also the container processes seem to be executed as the host's user/group 1000. The container can be configured to map the uid and gid of redmine user to different ids on host by passing the environment variables USERMAP_UID and USERMAP_GID. The following command maps the ids to user and group redmine on the host.

docker run --name=redmine -it --rm [options] \
  --env="USERMAP_UID=500" --env="USERMAP_GID=500" \
  sameersbn/redmine:6.0.2

Plugins

The functionality of redmine can be extended using plugins developed by the community. You can find a list of available plugins in the Redmine Plugins Directory. You can also search for plugins on github.

Please check the plugin compatibility with the redmine version before installing a plugin.

Installing Plugins

Plugins should be installed in the plugins directory at the data store. If you are following the readme verbatim, on the host this location would be /srv/docker/redmine/redmine/plugins.

mkdir -p /srv/docker/redmine/redmine/plugins

To install a plugin, simply copy the plugin assets to the plugins directory. For example, to install the recurring tasks plugin:

cd /srv/docker/redmine/redmine/plugins
git clone https://github.com/nutso/redmine-plugin-recurring-tasks.git

For most plugins this is all you need to do. With the plugin installed you can start the docker image normally. The image will detect that a plugin has been added (or removed) and automatically install the required gems and perform the plugin migrations and will be ready for use.

If the gem installation fails after adding a new plugin, please retry after removing the /srv/docker/redmine/redmine/tmp directory

In some cases it might be necessary to install additional packages and/or perform some post installation setup for a plugin to function correctly. For such case the image allows you to install a pre-install.sh and post-install.sh script at the /srv/docker/redmine/redmine/plugins directory that will be executed everytime the image is started.

For example, the recurring tasks plugin requires that you create a cron job to periodically execute a rake task. To achieve this, create the /srv/docker/redmine/redmine/plugins/post-install.sh file with the following content:

## Recurring Tasks Configuration

# get the list existing cron jobs for the redmine user
crontab -u redmine -l 2>/dev/null >/tmp/cron.redmine

# add new job for recurring tasks if it does not exist
if ! grep -q redmine:recur_tasks /tmp/cron.redmine; then
  echo '@hourly /sbin/entrypoint.sh app:rake redmine:recur_tasks RAILS_ENV=production >> log/cron_rake.log 2>&1' >>/tmp/cron.redmine
  crontab -u redmine /tmp/cron.redmine 2>/dev/null
fi

# remove the temporary file
rm -rf /tmp/cron.redmine

## End of Recurring Tasks Configuration

Now whenever the image is started the post-install.sh script will be executed and the required cron job will be installed.

If you need to install additional packages to satisfy a plugins dependencies then install such packages using the pre-install.sh script.

Previously this image packaged a couple of plugins by default. Existing users would notice that those plugins are no longer available. If you want them back, follow these instructions:

cd /srv/docker/redmine/redmine/plugins
wget http://goo.gl/iJcvCP -O - | sh

Please Note: this plugin install script is not maintained and you would need to fix it if required (especially broken links)

Reloading plugins for development

Changing files in /srv/docker/redmine/redmine/plugins won't be automatically loaded. If you want to reload the plugins without restarting the docker, you can run the following.

docker exec -it redmine redmine-install-plugins

Uninstalling Plugins

To uninstall plugins you need to first tell redmine about the plugin you need to uninstall. This is done via a rake task:

docker run --name=redmine -it --rm \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2 \
  app:rake redmine:plugins:migrate NAME=plugin_name VERSION=0

Once the rake task has been executed, the plugin should be removed from the /srv/docker/redmine/redmine/plugins/ directory.

rm -rf /srv/docker/redmine/redmine/plugins/plugin_name

Any configuration that you may have added in the /srv/docker/redmine/redmine/plugins/post-install.sh script for the plugin should also be removed.

For example, to remove the recurring tasks plugin:

docker run --name=redmine -it --rm \
  --volume=/srv/docker/redmine/redmine:/home/redmine/data \
  --volume=/srv/docker/redmine/redmine-logs:/var/log/redmine/ \
  sameersbn/redmine:6.0.2 \
  app:rake redmine:plugins:migrate NAME=recurring_tasks VERSION=0
rm -rf /srv/docker/redmine/redmine/plugins/recurring_tasks

Now when the image is started the plugin will be gone.

Themes

Just like plugins, redmine allows users to install additional themes. You can find a list of available themes in the Redmine Themes Directory

Installing Themes

Themes should be installed in the themes directory at the data store. If you are following the readme verbatim, on the host this location would be /srv/docker/redmine/redmine/themes.

mkdir -p /srv/docker/redmine/redmine/themes

To install a theme, simply copy the theme assets to the themes directory. For example, to install the gitmike theme:

cd /srv/docker/redmine/redmine/themes
git clone https://github.com/makotokw/redmine-theme-gitmike.git gitmike

With the theme installed you can start the docker image normally and the newly installed theme should be available for use.

Previously this image packaged a couple of themes by default. Existing users would notice that those themes are no longer available. If you want them back, follow these instructions:

cd /srv/docker/redmine/redmine/themes
wget http://goo.gl/deKDpp -O - | sh

Please Note: this theme install script is not maintained and you would need to fix it if required (especially broken links)

Reloading themes for development

Changing files in /srv/docker/redmine/redmine/themes won't be automatically loaded. If you want to reload the themes without restarting the docker, you can run the following.

docker exec -it redmine redmine-install-themes

Uninstalling Themes

To uninstall themes you simply need to remove the theme from the /srv/docker/redmine/redmine/themes/ directory and restart the image.

rm -rf /srv/docker/redmine/redmine/themes/theme_name

For example, to remove the gitmike theme:

rm -rf /srv/docker/redmine/redmine/themes/gitmike

Now when the image is started the theme will be not be available anymore.

Maintenance

Creating backups

Only available in versions >3.2.0-2, >3.1.3-1, >3.0.7-1 and >2.6.9-1

The image allows users to create backups of the Redmine installation using the app:backup:create command or the redmine-backup-create helper script. The generated backup consists of configuration files, uploaded files and the sql database.

Before generating a backup — stop and remove the running instance.

docker stop redmine && docker rm redmine

Relaunch the container with the app:backup:create argument.

docker run --name redmine -it --rm [OPTIONS] \
  sameersbn/redmine:6.0.2 app:backup:create

The backup will be created in the backups/ folder of the Data Store. You can change the location using the REDMINE_BACKUPS_DIR configuration parameter.

NOTE

Backups can also be generated on a running instance using:

docker exec -it redmine redmine-backup-create

To avoid undesired side-effects, you are advised against creating a backup on a running instance.

Restoring Backups

Only available in versions >3.2.0-2, >3.1.3-1, >3.0.7-1 and >2.6.9-1

Backups created using instructions from the Creating backups section can be restored using the app:backup:restore argument.

Before restoring a backup — stop and remove the running instance.

docker stop redmine && docker rm redmine

Relaunch the container with the app:backup:restore argument. Ensure you launch the container in the interactive mode -it.

docker run --name redmine -it --rm [OPTIONS] \
  sameersbn/redmine:6.0.2 app:backup:restore

A list of existing backups will be displayed. Select a backup you wish to restore.

To avoid this interaction you can specify the backup filename using the BACKUP argument to app:backup:restore, eg.

docker run --name redmine -it --rm [OPTIONS] \
  sameersbn/redmine:6.0.2 app:backup:restore BACKUP=1417624827_redmine_backup.tar

Automated backups

Only available in versions >3.2.0-2, >3.1.3-1, >3.0.7-1 and >2.6.9-1

The image can be configured to automatically create backups daily, weekly or monthly using the REDMINE_BACKUP_SCHEDULE configuration option.

Daily backups are created everyday at REDMINE_BACKUP_TIME, which defaults to 04:00. Weekly backups are created every Sunday at REDMINE_BACKUP_TIME. Monthly backups are created on the 1st of every month at REDMINE_BACKUP_TIME.

By default when automated backups are enabled, backups are held for a period of 7 days before they are deleted. When disabled, the backups are held for an infinite period of time. This behavior can be modified using the REDMINE_BACKUP_EXPIRY option.

Rake Tasks

The app:rake command allows you to run redmine rake tasks. To run a rake task simply specify the task to be executed to the app:rake command. For example, if you want to send a test email to the admin user.

docker run --name=redmine -d [OPTIONS] \
  sameersbn/redmine:6.0.2 app:rake redmine:email:test[admin]

You can also use docker exec to run rake tasks on running redmine instance. For example,

docker exec redmine /sbin/entrypoint.sh app:rake redmine:email:test[admin] RAILS_ENV=production

Similarly, to remove uploaded files left unattached

docker run --name=redmine -d [OPTIONS] \
  sameersbn/redmine:6.0.2 app:rake redmine:attachments:prune

Or,

docker exec redmine /sbin/entrypoint.sh app:rake redmine:attachments:prune RAILS_ENV=production

For a complete list of available rake tasks please refer www.redmine.org/projects/redmine/wiki/RedmineRake.

Upgrading

To upgrade to newer redmine releases, simply follow this 4 step upgrade procedure.

• Step 1: Update the docker image.

docker pull sameersbn/redmine:6.0.2

• Step 2: Stop and remove the currently running image

docker stop redmine
docker rm redmine

• Step 3: Create a backup

docker run --name redmine -it --rm [OPTIONS] \
    sameersbn/redmine:x.x.x app:backup:create

Replace x.x.x with the version you are upgrading from. For example, if you are upgrading from version 2.6.4, set x.x.x to 2.6.4

• Step 4: Start the image

docker run --name=redmine -d [OPTIONS] sameersbn/redmine:6.0.2

When an upgrade is in progress the variable REDMINE_WAS_UPDATED will be defined and set to yes. This allows easy integration of individual upgrade-steps via entrypoint.custom.sh, pre-install.sh, and post-install.sh.

Shell Access

For debugging and maintenance purposes you may want access the containers shell. If you are using docker version 1.3.0 or higher you can access a running containers shell using docker exec command.

docker exec -it redmine bash
