readystack/mattermost repository overview

⁠Mattermost Team Edition

readystack/mattermost:v11.11.0-CE-ubuntu24.04-r1

A hardened, cosign-signed, offline-rebuildable build of github.com/mattermost/mattermost v11.11.0 (AGPL-3.0; webapp and server templates/i18n/public are Apache-2.0), built clean-room from official upstream source by ReadyStack⁠.

⁠What you get

• Docker Scout — re-checked daily; today's grade and the reason for it are at https://readystack.dev/queue⁠.
• Signed — cosign signature by the ReadyStack release key; verify with cosign verify --key https://readystack.dev/keys/cosign.pub --insecure-ignore-tlog=true readystack/mattermost:v11.11.0-CE-ubuntu24.04-r1.
• Built from source, non-root.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is v11.11.0-CE-ubuntu24.04-r1 — the release on sale at readystack.dev. Release tags use the pattern <upstream-version>-CE-<base-os>-r<N>; the current one is hermetically built, signed, attested, and supported under your ReadyStack agreement.

• Earlier release tags (an older version or revision in the same pattern) are superseded. They stay pullable so existing deployments can pin them, but they are no longer patched or re-graded: move to the current release. A superseded release's build kit is available through support.

• Any tag beginning with internal- is an engineering-pipeline artifact published for build observability. It is unsupported, may change or disappear without notice, and must not be used in production.

# ✓ current release
docker pull readystack/mattermost:v11.11.0-CE-ubuntu24.04-r1

# ✗ unsupported (do not pull)
docker pull readystack/mattermost:internal-...

Each release tag is signed; verify with cosign verify --key https://readystack.dev/keys/cosign.pub --insecure-ignore-tlog=true readystack/mattermost:v11.11.0-CE-ubuntu24.04-r1 (ReadyStack keeps signatures off the public transparency log, so the check is key-only). Support: [email protected]⁠.

⁠Deployment

Single container running the mattermost server in the foreground, serving both the REST API and the compiled web client, against an EXTERNAL PostgreSQL database. This is Team Edition — the free, open-source edition — built from source with all Enterprise code removed rather than merely disabled.

docker run -d --name mattermost -p 8065:8065 -e MM_SQLSETTINGS_DATASOURCE='postgres://mmuser:PASSWORD@your-db:5432/mattermost?sslmode=disable' -v mm-data:/mattermost/data -v mm-config:/mattermost/config readystack/mattermost:v11.11.0-CE-ubuntu24.04-r1
