Setting Up Mattermost on Linux with Docker Compose: A Step-by-Step Guide

This guide will walk you through installing Mattermost on your Linux machine using Docker Compose, a user-friendly tool for managing containerized applications. Even if you’re new to Docker, don’t worry – we’ll break it down step-by-step!

Installing Docker and Docker Compose:

First things first, we need to install Docker, the engine that runs containerized applications, and Docker Compose, a tool to manage them.  Open a terminal window (usually Ctrl+Alt+T) and paste the following commands , pressing Enter after each:

apt update && 
apt upgrade -y &&
curl -fsSL https://get.docker.com -o get-docker.sh &&
sudo sh get-docker.sh &&
curl -SL https://github.com/docker/compose/releases/download/v2.13.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose &&
chmod +x /usr/local/bin/docker-compose &&
apt-get install docker-compose-plugin

Downloading the Mattermost Configuration:

Now, the fun part begins! We’ll use a handy tool called Git to download the configuration files needed to run Mattermost. In your terminal window, type:

git clone https://github.com/mattermost/docker
cd docker

This downloads the “docker” repository containing the Mattermost configuration and navigates you inside it.

Configuring Your Mattermost Server:

Here’s where you personalize your Mattermost experience. Inside the “docker” directory, you’ll find a file named “.env.example”. Copy this file and rename it to “.env”:

cp env.example .env

Open the “.env” file with a text editor and locate the “DOMAIN” variable.  Replace the placeholder text with the domain name or IP address where you want to access your Mattermost server (e.g., “[invalid URL removed]”).

Preparing the Server Environment:

Mattermost needs dedicated folders to store its data. Let’s create these folders and set appropriate permissions:

mkdir -p ./volumes/app/mattermost/{config,data,logs,plugins,client/plugins,bleve-indexes}
sudo chown -R 2000:2000 ./volumes/app/mattermost

This creates the folders and assigns ownership to the user that will run Mattermost.

Launching Mattermost!

We’re almost there!  To deploy Mattermost without the built-in Nginx reverse proxy (which handles web traffic), run this command in your terminal:

sudo docker compose -f docker-compose.yml -f docker-compose.without-nginx.yml up -d

This starts Mattermost in detached mode, meaning it runs in the background.  You can now access your Mattermost server by opening this URL in a web browser:

<Server-IP>:8065  (Replace "<Server-IP>" with your actual server IP address)

Issuing SSL Certificate with Nginx Proxy Manager:

If you have Nginx Proxy Manager already installed on your server, follow these steps to issue an SSL certificate:

• Open the Nginx Proxy Manager UI.
• Navigate to the SSL Certificates section.
• Click on “Create Certificate.”
• Enter the domain name corresponding to your Mattermost server.
• Follow the on-screen instructions to complete the SSL certificate issuance process.

Stopping Mattermost:

If you ever need to stop your Mattermost server, use this command:

sudo docker compose -f docker-compose.yml -f docker-compose.nginx.yml down

Exploring Further Customization:

The provided configuration offers a great starting point.  For more advanced customization options, refer to the official Mattermost documentation :

Congratulations! You’ve successfully installed your own Mattermost server using Docker Compose. Now, you can create a team workspace, invite colleagues, and enjoy secure and efficient communication!
