LimeSurvey

#IMPORTANT NOTE for installations from 4.0.0 to 5.0.8 (fixed if you use a NEW install from 5.0.8.1 onwards) - POTENTIAL DATA LOSS

If you are using a version of this container from 4.0.0 to 5.0.8 inclusive AND your users have encrypted any data within LimeSurvey - please ensure to make a backup of /var/www/html/application/config/security.php before updating your image.

An example of how to do this is below, assuming the container name is 'some-limesurvey':

$ docker cp some-limesurvey:/var/www/html/application/config/security.php /tmp/security.php

Then update to 5.0.8.1 or greater. You can then copy the security.php file back:

$ docker cp /tmp/security.php some-limesurvey:/var/www/html/application/config/security.php

5.0.8.1 or greater will persist the config directory.

This docker image is for Limesurvey on apache/php in its own container. It accepts environment variables to update the configuration file. On first run it will automatically create the database if a username and password are supplied, and on subsequent runs it can update the administrator password if provided as an environment variable.

Volumes are specified for plugins and upload directories for persistence.

• -e LIMESURVEY_PHP_SESSION_SAVE_PATH=... (defaults to '' - Leave blank or don't set to use default sessions. Set to the desired session path if you want to specify. Must use in conjuction with LIMESURVEY_PHP_SESSION_SAVE_HANDLER

If set to "BaltimoreCyberTrustRoot.crt.pem", the certificate is downloaded before the application is started (see https://learn.microsoft.com/en-us/azure/mysql/single-server/how-to-configure-ssl#step-1-obtain-ssl-certificate). If set to "global-bundle.pem" - will download Amazon certificate from: https://truststore.pki.rds.amazonaws.com/global/global-bundle.pem - SECURITY NOTE: By default this image sets PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT to "false" for compatability reasons
• -e TZ=... Time zone name. If set, will configure PHP and LimeSurvey to use this time zone

If the LIMESURVEY_DB_NAME specified does not already exist on the given MySQL server, it will be created automatically upon startup of the limesurvey container, provided that the LIMESURVEY_DB_USER specified has the necessary permissions to create it.

If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used:

$ docker run --name some-limesurvey --link some-mysql:mysql -p 8080:80 -d adamzammit/limesurvey

Then, access it via http://localhost:8080 or http://host-ip:8080 in a browser.

If you'd like to use an external database instead of a linked mysql container, specify the hostname and port with LIMESURVEY_DB_HOST along with the password in LIMESURVEY_DB_PASSWORD and the username in LIMESURVEY_DB_USER (if it is something other than root):

$ docker run --name some-limesurvey -e LIMESURVEY_DB_HOST=10.1.2.3:3306 \
    -e LIMESURVEY_DB_USER=... -e LIMESURVEY_DB_PASSWORD=... -d adamzammit/limesurvey
