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

SHARELATEX_DATA_PATH

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

• Default: data/sharelatex

SHARELATEX_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 https://github.com/overleaf/toolkit/pull/77 the listen mode of the application container was changed to localhost only, so the value of SHARELATEX_LISTEN_IP must be set to the public IP address for direct container access.

Setting SHARELATEX_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

SHARELATEX_PORT

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

• Default: 80

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

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

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

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 SHARELATEX_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
