Deploy with Docker & Docker Compose

As of December 15, 2023, Rocket.Chat has ceased support for connections from cloud services and official mobile/desktop apps to workspaces running legacy versions outside our support window. Users on unsupported legacy servers are advised to upgrade to the latest Rocket.Chat version to ensure continued access to cloud, mobile, and desktop applications. Each Rocket.Chat version is supported for six months post-release.

Deploying Rocket.Chat with Docker and Docker-compose is a straightforward and highly recommended deployment method due to its simplicity and flexibility. This guide will walk you through the essential steps, whether you're a seasoned Docker expert or new to containerization, ensuring a smooth deployment for your Rocket.Chat workspace.

In this guide, you'll learn how to:

Step 1: Install Docker and Docker Compose

Ensure you have Docker and Docker Compose (Docker Compose v2 is required) installed and operational. If you don't have them installed, you can conveniently set them up using Docker's official helper script:
```
curl -L https://get.docker.com | sh
```
To run Docker commands without using sudo, add the current user to the Docker group. If you are unsure who the user is, check the current user by running:
```
whoami
```
Now run the following command. Substitute $USER with the result you get from executing the above command.
```
sudo usermod -aG docker $USER
sudo reboot
```
If you are using a firewall, you may need to whitelist some URLs to communicate with our cloud services. See Firewall Configuration for the complete list.

Step 2: Fetch the compose file

Go to your preferred directory, create a compose.yml file, and copy the content from Rocket.Chat’s Docker official image.

Alternatively, you can use the curl command to download the compose.yml file by executing this command:

curl -L https://raw.githubusercontent.com/RocketChat/Docker.Official.Image/master/compose.yml -O

Step 3: Create a `.env` file

Modifying the configurations in the compose file directly is strongly discouraged. Instead, use environment variables. You can set environment variables using a .env file.

Remember to uncomment the variables you are updating in the .env file.

In your project directory, create a .env file with the following command and paste the contents of the official .env.example file.
```
nano .env
```
Set the RELEASE variable in the .env to your desired Rocket.Chat version. See our releases page and available docker images. Keeping the default release as latest is not recommended.
If you're deploying a production workspace with a domain, update your .env file with the following details:
- ROOT_URL: Specify the intended URL for your workspace. For example, http://<your-domain>.
- HOST_PORT: Set this to 80. Confirm that no other services are running on port 80 and that your firewall permits traffic on this port.
  - Skip this step if you are deploying a test workspace on localhost.
  - If you plan to enable HTTPS for your workspace domain, skip setting the HOST_PORT and ROOT_URL here and proceed to Enable HTTPS for Docker after starting the Rocket.Chat container.
If you’ve received a registration token from our Sales team or Rocket.Chat Cloud, you can use it to register your workspace automatically. To do this, add the token to the .env file like this:
```
REG_TOKEN=your_token_here
```
- Adding the registration token to the .env file is optional. You can also register your workspace during configuration after deployment.
- Once registration is complete (confirmed when server starts), the token is no longer needed. If stored in the .env file, it can be removed as the registration is stored in the database clould settings.
If you’re using an existing MongoDB installation, such as MongoDB Atlas as the database provider, edit the value of the MONGO_URL variable to your connection string in this format:
```
MONGO_URL=mongodb://<user>:<pass>@host1:27017,host2:27017,host3:27017/<databaseName>?replicaSet=<replicaSet>&ssl=true&authSource=admin
```
Save the .env file and start up the container by executing this command:
```
docker compose up -d
```
This command will:
1. Start a MongoDB service named mongodb.
2. Start a service rocketchat, which will also wait for mongodb to be ready.
MongoDB ensures continuous 24 x 7 operations and live backup, reducing the need for frequent restarts. Refer to the MongoDB documentation for proper server operation and management. Optionally, manage messages and configurations by uncommenting the volume mounts, and ensuring a data subdirectory is available for data storage and mounting.

Step 4: Access your Rocket.Chat workspace

To access your workspace, visit http://localhost:3000 if you deployed a test workspace on localhost. However, if you deployed a production workspace with a domain, you can access your workspace through the specified ROOT_URL . Follow the configuration prompts to configure your workspace. During the configuration steps, your workspace and email are registered to the Rocket.Chat Cloud portal, from where you can manage your workspace and subscriptions.

Workspace Administration: Administrators and owners can set and manage various configurations.
Marketplace: Explore the available apps to enhance your workspace.

Enable HTTPS for your Rocket.Chat workspace

Your domain should only be accessible via HTTPS to access your workspace securely. If your domain is not set up with HTTPS already, the following examples describe how to set it up using a reverse proxy, such as Traefik or Nginx.

We recommend using Traefik as it’s shipped with our official Docker image.

Traefik

Nginx

Traefik

You can secure your Rocket.Chat Docker instance with TLS/SSL certificates from Let's Encrypt. Using Traefik as a reverse proxy, the certificates are automatically generated, enabling safe access to your Rocket.Chat instance via HTTPS on your specified domain.

Before you proceed, confirm that the correct A record (optionally CNAME) is set for your domain going to your server IP.

Update the following variables in your .env file. If you don't have one, create a .env file following our example.
1. LETSENCRYPT_EMAIL: Your required email for the TLS certificates.
2. DOMAIN: Your domain or subdomain name only. Avoid adding https:// or any trailing slashes. Confirm that this domain resolves to the server IP address.
3. RELEASE : Your preferred Rocket.Chat release. See the releases page to know more about our releases.
4. ROOT_URL : Set the value to " https://your-domain.com," replacing "your-domain.com" with the domain name you want to use.
5. BIND_IP: Set to 127.0.0.1
```
LETSENCRYPT_EMAIL= # your email, required for the tls certificates
DOMAIN= # set this to your domain name or subdomain, not trailing slashes or https://, just the domain
RELEASE= # set the rocketchat release
ROOT_URL= # set this to https://${DOMAIN} replace ${DOMAIN} with the actual domain
BIND_IP=127.0.0.1
```

Download the Traefik template by running the following command:

curl -LO \
    https://raw.githubusercontent.com/RocketChat/Docker.Official.Image/master/traefik.yml

Recreate the existing Rocket.Chat container:

docker compose up -d rocketchat --force-recreate

Start traefik:
```
docker compose -f traefik.yml up -d
```

Wait for the TLS certificates to generate and Rocket.Chat to restart. Then, access your Rocket.Chat workspace securely at https://your-domain.com, using the actual domain name you configured.

Great job! You have successfully enabled HTTPs on your Rocket.Chat workspace with Traefik.

Nginx

If you prefer using Nginx as your reverse proxy, you can secure your Rocket.Chat workspace by configuring Nginx with a TLS/SSL certificate from Let's Encrypt. Follow these steps to complete the configuration:

Get an SSL certificate from Let's Encrypt

Use Let's Encrypt to get a free & open-source SSL certificate by following these steps:

Install certbot using using the relevant package manager for your version of Linux. For Debian-based distributions such as Debian and Ubuntu use :
```
sudo apt update
sudo apt install certbot
```
For RPM-based distributions such as Redhat and Centos, use:
```
sudo yum install yum-utils
sudo yum install nginx
```
The installation commands may vary based on your Linux distribution and version.

Obtain a certificate from Let's Encrypt by running this command (a second or more domains are optional):

sudo certbot certonly --standalone --email <[email protected]> -d <domain.com> -d <subdomain.domain.com>

Configure Nginx web server with TLS/SSL

Rocket.Chat is usually set to run on port 3000 by default. However, you can make it more accessible to your users by using Nginx as a reverse proxy. This will link your domain name to the Rocket.Chat server running on that port. By doing this, your users can access your workspace through your domain name instead of directly using the port in the URL. Follow these steps:

Install Nginx web server:
```
sudo apt-get install nginx
```

Backup the default config file for reference:

cd /etc/nginx/sites-available
sudo mv default default.reference

Create a new site configuration for Rocket.Chat:
```
sudo nano /etc/nginx/sites-available/default
```

Paste the following in the new file:

server {
     listen 443 ssl;

     server_name <ABC.DOMAIN.COM>; #replace <ABC.DOMAIN.COM> with your domain name

     ssl_certificate /etc/letsencrypt/live/<ABC.DOMAIN.COM>/fullchain.pem; #replace <ABC.DOMAIN.COM> with your domain name
     ssl_certificate_key /etc/letsencrypt/live/<ABC.DOMAIN.COM>/privkey.pem; #replace <ABC.DOMAIN.COM> with your domain name
     ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
     ssl_prefer_server_ciphers on;
     ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';

     root /usr/share/nginx/html;
     index index.html index.htm;

     # Make site accessible from http://localhost/
     server_name localhost;

     location / {
         proxy_pass http://localhost:3000/;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_set_header Host $http_host;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header X-Forwarded-Proto http;
         proxy_set_header X-Nginx-Proxy true;
         proxy_redirect off;
     }
 }

 server {
     listen 80;

     server_name <ABC.DOMAIN.COM>; #replace <ABC.DOMAIN.COM> with your domain name

     return 301 https://$host$request_uri;
 }

Replace ABC.DOMAIN.COM with your domain name.

Test the Nginx configuration to make sure there are no syntax errors:
```
sudo nginx -t
```
If the syntax test is successful, restart Nginx:
```
sudo systemctl restart nginx
```
If you have security group restrictions, allow TCP/22 from your current IP for SSH connections and TCP/443 from the IP you plan to use for access.

Open a web browser and access your Rocket.Chat workspace securely at https://your-domain.com, using the actual domain name you configured.

Great job! You have successfully enabled HTTPs on your Rocket.Chat workspace with Nginx.

Update Rocket.Chat on Docker

Before you proceed, see the general guidelines for updating Rocket.Chat.
Updating the Rocket.Chat image doesn't affect your data since it exists in the Mongo image. Before proceeding with the update, ensure that the version of your MongoDB is compatible with the intended release.

Using Docker & Docker compose, you can update your rocketchat docker image to the latest or preferred version of Rocket.Chat. To update your Rocket.Chat version,

For a specific version, modify the RELEASE variable in the .env file to point to the Docker image tag of that version. Alternatively, you can edit the compose.yml file to point to the desired Rocket.Chat version.
Changing version in .env
In the .env file, change the RELEASE value to your specified version.
```
RELEASE=<desired version>
```
Changing version in compose.yml
In the compose.yml file, change the rocketchat service image value to point to an image in the rocketchat registry image with a tag of your desired version.
```
services:
  rocketchat:
    image:registry.rocket.chat/rocketchat/rocket.chat:<desired version>
```

Now, stop, remove, and restart the existing container with these commands:

docker compose stop rocketchat
docker compose rm rocketchat
docker compose up -d rocketchat

See the official documentation for more details on Rocket.Chat Docker images.

Set Rocket.Chat deployment environment variable on Docker

Enviroment variables are additional settings that impacts your workspace deployment and configuration. To set up an environment variable in Docker,

Open your compose.yml file:
```
nano compose.yaml
```
Add the environment variable under the environment section of the rocketchat service. For example, to set the INSTANCE_IP variable:
```
services:
  rocketchat:
    ...
    environment:
      ...
      INSTANCE_IP: 172.30.12.131
```
Tip: This is the same section where ROOT_URL, MONGO_URL, etc is defined.
Restart your Rocket.Chat container to apply the changes:
```
docker compose stop rocketchat
docker compose rm rocketchat
docker compose up -d rocketchat
```
If you haven't deployed your workspace yet, start it with:
```
docker compose up -d
```

For a full list of available environment variables, refer to Deployment Environment Variables.

Additional steps

Rocket.Chat Docker images

You can use any of the following Docker images according to your needs:

Official image (stable and tested): The official Docker images repository is responsible for maintaining and controlling Rocket.Chat's official stable image through Docker. It is also reviewed by the Docker committee.
```
docker pull registry.rocket.chat/rocketchat/rocket.chat
```
Latest release image: This image holds the latest Rocket.Chat updates on the Docker repository. The release may be from the develop or master branch. You can use this to test some of the latest updates.
```
docker pull registry.rocket.chat/rocketchat/rocket.chat:latest
```
Using the latest image tag for production deployments is not recommended.
Preview image: The Rocket.Chat preview image deploys a container with a database inside. It's useful for quickly trying or running tests and does not require a dedicated database installation.

Docker Hub

Specific release image: You can set up your Rocket.Chat workspace with a specific release image. Select the release you need from the Docker hub tags and use it to run the following command:
```
docker pull registry.rocket.chat/rocketchat/rocket.chat:<release-tag>
```
Bleeding-edge untested develop build image: This is an image maintained at Rocket.Chat's Docker repository. This update comes from the develop (untested) branch, which contains the latest updates for those who want to work with the newest features.
```
docker pull registry.rocket.chat/rocketchat/rocket.chat:develop
```

Monitoring and logging your deployment

Effective logging helps you monitor the health and status of your Rocket.Chat deployment. This section covers logging for Rocket.Chat, MongoDB, and reverse proxies like Traefik or Nginx.

Logging Rocket.Chat

To check the status and logs of your Rocket.Chat container, follow these steps:

Use any of the following commands to list containers running in your Docker environment:

docker ps        # Shows currently running containers with details like ID, status, and ports  
docker ps -a     # Lists all containers, including stopped ones  
docker ps -q     # Displays only container IDs for a concise view  
docker compose ps  # Lists services managed by Docker Compose

Once you identify your Rocket.Chat container, you can inspect its logs using any of these commands:

docker compose logs -f <Service_Name>  # If using Docker Compose, this follows real-time logs  
docker logs <Container_Name>       # Displays logs for the specific Rocket.Chat container  
docker logs -f <Container_Name>    # Shows real-time logs (follow mode)  
docker logs --tail 10 <Container_Name> # Displays the last 10 lines of logs

Note:
Replace <Container_Name> and <Service_Name> with the appropriate values such as docker compose logs -f rocketchat.
Rocket.Chat logs to stdout, so there isn't a specific log file within the container. The Docker logging system captures these stdout logs, making them accessible through the docker logs command

Logging MongoDB

MongoDB is a crucial part of your Rocket.Chat deployment. Monitoring its logs can help identify database-related issues.

View MongoDB logs by running any of these commands:

docker logs -f <MongoDB_Container_Name>  # View real-time logs  
docker logs --tail 20 <MongoDB_Container_Name>  # Show the last 20 log lines  
docker compose logs -f mongodb  # If using Docker Compose

To inspect MongoDB’s health, run:

docker exec -it <MongoDB_Container_Name> mongosh --eval "db.runCommand({ serverStatus: 1 })"

This returns detailed server status information.

Replace <Container_Name> with the appropriate values.

Logging reverse proxy (Traefik or Nginx)

If you use a reverse proxy, checking its logs can help diagnose connectivity and SSL issues.

If Traefik is handling requests, check its logs with:

docker logs -f <Traefik_Container_Name>  # Show real-time logs  
docker logs --tail 50 <Traefik_Container_Name>  # Show the last 50 log lines

If using Nginx as a reverse proxy, logs are stored inside the container at /var/log/nginx/. To view logs, run:

docker exec -it <Nginx_Container_Name> cat /var/log/nginx/access.log  # Access logs  
docker exec -it <Nginx_Container_Name> cat /var/log/nginx/error.log   # Error logs

To continuously monitor logs in real-time, run:

docker exec -it <Nginx_Container_Name> tail -f /var/log/nginx/access.log

Docker Mongo backup and restore

To back up your MongoDB database in Docker,

Run the following command on your terminal to list out all running containers:
```
docker ps -a
```
Take note of your mongo container name.
Run this command to dump the database into a binary file db.dump
```
docker exec <container_name> sh -c 'mongodump --archive' > db.dump
```
When successful, you should see db.dump file in the current directory.

To restore the backup,

Run the following command:

docker exec -i <container_name> sh -c 'mongorestore --archive' < db.dump

You can export your database dump directly to MongoDB Atlas by simply running
mongorestore --uri mongodb+srv://<user>:<password>@cluster0.w2btl.mongodb.net --archive=db.dump
