Configuration: overleaf.rc

This document describes the variables that are supported in the config/overleaf.rc file. This file consists of variable definitions in the form NAME=value. Lines beginning with # are treated as comments.

Note: we recommend that you re-create the docker containers after changing anything in overleaf.rc or variables.env, by running bin/docker-compose down, followed by bin/up

Variables

PROJECT_NAME

Sets the value of the --project-name flag supplied to docker-compose. This is useful when running multiple instances of Overleaf on one host, as each instance can have a different project name.

  • Default: overleaf

OVERLEAF_DATA_PATH

Sets the path to the directory that will be mounted into the main sharelatex container, and used to store project and compile data. This can be either a full path (beginning with a /), or relative to the base directory of the toolkit.

  • Default: data/sharelatex

OVERLEAF_LOG_PATH

Sets the path to the directory that will be mounted into the main sharelatex container, and used for making application logs available on the Docker host. This can be either a full path (beginning with a /), or relative to the base directory of the toolkit.

Remove the config entry to disable the bind-mount. When not set, logs will be discarded when recreating the container.

  • Default: not set

OVERLEAF_LISTEN_IP

Sets the host IP address(es) that the container will bind to. For example, if this is set to 0.0.0.0, then the web interface will be available on any host IP address.

Since #77 the listen mode of the application container was changed to localhost only, so the value of OVERLEAF_LISTEN_IP must be set to the public IP address for direct container access.

Setting OVERLEAF_LISTEN_IP to either 0.0.0.0 or the external IP of your host will typically cause errors when used in conjunction with the TLS Proxy.

  • Default: 127.0.0.1

OVERLEAF_PORT

Sets the host port that the container will bind to. For example, if this is set to 8099 and OVERLEAF_LISTEN_IP is set to 127.0.0.1, then the web interface will be available on http://localhost:8099.

  • Default: 80

OVERLEAF_IMAGE_NAME

Docker image as used by the Server Pro/CE application container. This is just the Docker image name, the Docker image tag is sourced from config/version.

  • Default:
    • Server Pro: quay.io/sharelatex/sharelatex-pro
    • Community Edition: sharelatex/sharelatex

SERVER_PRO

When set to true, tells the toolkit to use the Server Pro image (quay.io/sharelatex/sharelatex-pro), rather than the default Community Edition image (sharelatex/sharelatex).

  • Default: false

SIBLING_CONTAINERS_ENABLED

When set to true, tells the toolkit to use the "Sibling Containers" technique for compiling projects in separate sandboxes, using a separate docker container for each project. See the legacy documentation on Sandboxed Compiles for more information.

Requires SERVER_PRO=true

  • Default: false

DOCKER_SOCKET_PATH

Sets the path to the docker socket on the host machine (the machine running the toolkit code). When SIBLING_CONTAINERS_ENABLED is true, the socket will be mounted into the container, to allow the compiler service to spawn new docker containers on the host.

Requires SIBLING_CONTAINERS_ENABLED=true

  • Default: /var/run/docker.sock

GIT_BRIDGE_ENABLED

Set to true to enable the git-bridge feature (Server Pro only).

User documentation: https://www.overleaf.com/learn/how-to/Git_integration

  • Default: false

GIT_BRIDGE_IMAGE

Docker image as used by the git-bridge container (Server Pro only). This is just the Docker image name, the Docker image tag is sourced from config/version.

  • Default: quay.io/sharelatex/git-bridge

GIT_BRIDGE_DATA_PATH

Sets the path to the directory that will be mounted into the git-bridge container (Server Pro only), and used to store the git-repositories. This can be either a full path (beginning with a /), or relative to the base directory of the toolkit.

  • Default: data/git-bridge

GIT_BRIDGE_LOG_LEVEL

Configure the logging level of the git-bridge container. Available levels: TRACE, DEBUG, INFO, WARN, ERROR.

  • Default: INFO

MONGO_ENABLED

When set to true, tells the toolkit to create a MongoDB container, to host the database. When set to false, this container will not be created, and the system will use the MongoDB database specified by MONGO_URL instead.

  • Default: true

MONGO_URL

Specifies the MongoDB connection URL to use when MONGO_ENABLED is false

  • Default: not set

MONGO_DATA_PATH

Sets the path to the directory that will be mounted into the mongo container, and used to store the MongoDB database. This can be either a full path (beginning with a /), or relative to the base directory of the toolkit. This option only affects the local mongo container that is created when MONGO_ENABLED is true.

  • Default: data/mongo

MONGO_IMAGE

Docker image as used by the MongoDB container. This is just the name of the Docker image, the Docker image tag should go into MONGO_VERSION (see below).

  • Default: mongo

MONGO_VERSION

MongoDB version as used by the MongoDB container. The value must start with the major MongoDB version and a dot, e.g. 6.0 or 6.0-with-suffix.

  • Default: 6.0

REDIS_ENABLED

When set to true, tells the toolkit to create a Redis container, to host the redis database. When set to false, this container will not be created, and the system will use the Redis database specified by REDIS_HOST and REDIS_PORT instead.

  • Default: true

REDIS_HOST

Specifies the Redis host to use when REDIS_ENABLED is false

  • Default: not set

REDIS_PORT

Specifies the Redis port to use when REDIS_ENABLED is false

  • Default: not set

REDIS_DATA_PATH

Sets the path to the directory that will be mounted into the redis container, and used to store the Redis database. This can be either a full path (beginning with a /), or relative to the base directory of the toolkit. This option only affects the local redis container that is created when REDIS_ENABLED is true.

  • Default: data/redis

REDIS_IMAGE

Docker image as used by the Redis container.

  • Default: redis:6.2

REDIS_AOF_PERSISTENCE

Turn on AOF (Append Only File) persistence for Redis. This is the recommended configuration for Redis persistence.

For additional details, see https://github.com/overleaf/overleaf/wiki/Data-and-Backups/#redis

  • Default: true

NGINX_ENABLED

When set to true, tells the toolkit to create an NGINX container, to act as a TLS Proxy.

  • Default: false

NGINX_CONFIG_PATH

Path to the NGINX config file to use for the TLS Proxy.

  • Default: config/nginx/nginx.conf

TLS_PRIVATE_KEY_PATH

Path to the private key to use for the TLS Proxy.

  • Default: config/nginx/certs/overleaf_key.pem

TLS_CERTIFICATE_PATH

Path to the public certificate to use for the TLS Proxy.

  • Default: config/nginx/certs/overleaf_certificate.pem

NGINX_TLS_LISTEN_IP

Sets the host IP address(es) that the TLS Proxy container will bind to for https. For example, if this is set to 0.0.0.0 then the https web interface will be available on any host IP address.

Typically this should be set to the external IP of your host.

  • Default: 127.0.1.1

TLS_PORT

Sets the host port that the TLS Proxy container will bind to for https.

  • Default: 443

NGINX_HTTP_LISTEN_IP

Sets the host IP address(es) that the TLS Proxy container will bind to for http redirect. For example, if this is set to 127.0.1.1 then http connections to 127.0.1.1 will be redirected to the https web interface.

Typically this should be set to the external IP of your host. Do not set it to 0.0.0.0 as this will typically cause a conflict with OVERLEAF_LISTEN_IP.

  • Default: 127.0.1.1

NGINX_HTTP_PORT

Sets the host port that the TLS Proxy container will bind to for http.

  • Default: 80
