Deployment Environment Variables

Configuring Rocket.Chat via environment variables
Environmental variables can be specified to affect how the workspace is deployed or affect the workspace settings and configuration. Setting the deployment environment variables depends on the deployment method of choice. This topic takes you through the mandatory and optional deployment environment variables for you to successfully deploy your workspace as per your needs.
Using the most common deployment method Deploy with Docker & Docker Compose these variables can be set in the compose.yml file.

Mandatory Environment Variables

Name
Description
Comment
ROOT_URL
The URL where your Rocket.Chat instance will be hosted on. In other words the URL you will enter on your browser to access Rocket.Chat.
Format is [protocol]://[domain or ip][: optional port]/[optional path]
PORT
Port your Rocket.Chat instance will bind to.
If served under a FQDN (which is recommended) this doesn't matter much, as long as the configured one is not in reserved range and doesn't collide with any other services.
MONGO_URL
MongoDB connection string.
Read the official documentation of MongoDB to understand better. This also somewhat depends on your deployment method of choice.
MONGO_OPLOG_URL
MongoDB connection string to the local database.
Similar to the above, except this one points directly to the local database. E.g. mongodb://localhost:27017/local

Optional Environment Variables

Name
Description
Comment
BIND_IP
Which IP the node (or main Rocket.Chat) process will bind to.
If intended to be accessed under a domain, which is recommended, users should set this to the loopback address (i.e. 127.0.0.1) or any private IP in the host that's accessible via a reverse proxy or load balancer. This will ensure the instance isn't accessible via any IP that isn't intended.
ADMIN_USERNAME
Admin user's username.
Admin user can be created automatically on deployment. Set this to your admin user's desired username. Mandatory if any of the other ADMIN_* variables are passed for a successful account creation.
ADMIN_NAME
Admin user's name.
Mandatory if any of the other ADMIN_* variables are passed for a successful account creation.
ADMIN_PASS
Admin user's password (in plaintext).
Mandatory if any of the other ADMIN_* variables are passed for a successful account creation.
ADMIN_EMAIL
Admin user's email address.
Mandatory if any of the other ADMIN_* variables are passed for a successful account creation.
After configuring the mandatory and optional deployment environment variables, see how to manage your workspace settings with environment variables in the next topic.
Rocket.Chat versions receive support for six months after release.
