Permission issues on M1 Mac

If you're deploying the Mattermost server using Docker on an M1 Mac and encountering permission issues in the Docker container, re-create the required directories and set their permissions, then skip the following command because it causes the deploy to stop working.

sh
sudo chown -R 2000:2000 ./volumes/app/mattermost

If you're experiencing issues deploying on Docker generally, ensure the docker daemon is enabled and running:

sh
sudo systemctl enable --now docker

To remove all data and settings for your Mattermost deployment:

sh
sudo rm -rf ./volumes

TLS and NGINX issues

Install a different version of Mattermost

  1. Shut down your deployment.

  2. Run git pull to fetch any recent changes to the repository, paying attention to any potential env.example changes.

  3. Adjust the MATTERMOST_IMAGE_TAG in the .env file to point your desired enterprise or team image version.

    For production environments, we recommend using specific version tags such as MATTERMOST_IMAGE_TAG=release-10.5 rather than generic tags like MATTERMOST_IMAGE_TAG=release-10. Generic release-x tags are intended for development use only and do not automatically receive new patch releases within that major version. Using specific version tags ensures a more reproducible and deterministic environment for your production deployment.

  4. Redeploy Mattermost.

Unintentional version downgrades

If you experience an unintentional downgrade when using generic MATTERMOST_IMAGE_TAG=release-x tags, this is because these tags are designed for development use and may not point to the latest patch release within that major version.

Solution: Use a more specific version tag for your Docker image, such as MATTERMOST_IMAGE_TAG=release-10.5, to avoid unexpected version changes and ensure consistent deployments.

<Note>

A pipeline improvement is in progress to ensure that generic release-x tags are updated to the latest version from the corresponding release branch. Once this improvement is implemented, the behavior of these tags will be more predictable.
