Docker & Docker Compose

Deploying Rocket.Chat with Docker and Docker Compose is as easy as it can get.

Installing Docker and Docker Compose

  • If you don't have it already, make sure you have Docker and Docker-compose (v2 is required) installed and operational. To quickly do that you can use Docker's official helper script
curl -L https://get.docker.com | sh
  • Add the current user to the docker group and reboot in order to run docker without using sudo by executing:
sudo usermod -aG docker $USER
sudo reboot

Fetching Compose file

  • Navigate to any directory of your choice and create a docker-compose.yml based on our example. OR you can download it directly by executing the following command on your terminal.
curl -L https://raw.githubusercontent.com/RocketChat/Docker.Official.Image/master/compose.yml -O

Editing Variables:

If you are using MongoDB Atlas as the database provider, edit the value of the MONGO_URL variable in your compose file to be your connection string in this format

MONGO_URL=mongodb://<user>:<pass>@host1:27017,host2:27017,host3:27017/<databaseName>?replicaSet=<replicaSet>&ssl=true&authSource=admin

Environment variables are set using a .env file. See the example here. If you cloned the repo initially, you can just rename the example file by

cp env.example .env

  • Set the RELEASE variable in the .envto your desired Rocket.Chat version. See releases here.
    Keeping the default latest is not recommended (More at Docker Images Available )

  • Edit ROOT_URL from the default http://localhost:3000 to match your domain name or IP address as you wish

  • If you have a registration token to register the workspace automatically you can provide it with:

    REG_TOKEN={your token here} docker-compose up -d

  • Next, start up the container by executing:

docker compose up -d

This is going to:

  1. Start a MongoDB service named mongodb.
  2. Start a service rocketchat, that will also wait for mongodb to be ready.

Mongo supports 24 x 7 operations and live backup. You should not need to restart it too frequently. See MongoDB documentation for proper operation and management of a Mongo server.

Optionally, if you want to manage your messages and configuration information, edit the file again to uncomment the volume mounts. Make sure you have a data subdirectory to mount and store the data.

Updating Rocket.Chat Docker Image

To update the rocketchat docker image to the latest version, update the RELEASE value in your .env file, then simply run docker compose up -d. Your data should not be affected by this, since it's located in the mongo image.
