Mattermost is a Slack-like team messenger focused on development and DevOps: channels, threads, incident playbooks and integrations with GitLab, GitHub and Jira.
A self-hosted install keeps conversations and files on your server, while webhooks and bots let you post notifications to channels from CI, monitoring and your own services.
The command deploys the official mattermost/docker stack with PostgreSQL, without the bundled Nginx.

Mattermost FAQ
Didn’t find an answer? Message @ExpressHost_SupportBot.
Do I need a license?
No. The Enterprise Edition image is installed by default: without a key it runs with the free features, and paid features are unlocked with a license.
How do I update?
Change MATTERMOST_IMAGE_TAG in .env and restart the stack with the same docker compose ... up -d command.
Where is the data stored?
In /opt/mattermost/volumes: the application's files and config, as well as the PostgreSQL database.
Mattermost installs at checkout — in the bot.
