Install with SSL certificate

  1. Put your SSL certificate as ./volumes/web/cert/cert.pem and the private key that has
    no password as ./volumes/web/cert/key-no-password.pem. If you don't have
    them you may generate a self-signed SSL certificate.

  2. Open http://your.domain with your web browser.

Starting/Stopping

Start

docker-compose start

Stop

docker-compose stop

Update

Make sure to backup Mattermost data before proceeding.

docker-compose down
git pull
docker-compose build
docker-compose up -d

Removing

Remove the containers

docker-compose stop && docker-compose rm

Remove the data and settings of your mattermost instance

sudo rm -rf volumes

Database Backup

When AWS S3 environment variables are specified on db docker container, it enables Wal-E backup to S3.

docker run -d --name mattermost-db \
    -e AWS_ACCESS_KEY_ID=XXXX \
    -e AWS_SECRET_ACCESS_KEY=XXXX \
    -e WALE_S3_PREFIX=s3://BUCKET_NAME/PATH \
    -e AWS_REGION=us-east-1
    -v ./volumes/db/var/lib/postgresql/data:/var/lib/postgresql/data
    -v /etc/localtime:/etc/localtime:ro
    db

All four environment variables are required. It will enable completed WAL segments sent to archive storage (S3). The base backup and clean up can be done through the following command:

# base backup
docker exec mattermost-db su - postgres sh -c "/usr/bin/envdir /etc/wal-e.d/env /usr/local/bin/wal-e backup-push /var/lib/postgresql/data"
# keep the most recent 7 base backups and remove the old ones
docker exec mattermost-db su - postgres sh -c "/usr/bin/envdir /etc/wal-e.d/env /usr/local/bin/wal-e delete --confirm retain 7"

Those tasks can be executed through a cron job or systemd timer.

2.x. Run these commands in the latest mattermost-docker directory.

docker-compose rm -f app
docker-compose build app
docker-compose run app -upgrade_db_30
docker-compose up -d

See the offical Upgrade Guide for more details.

Known Issues

  • Do not modify the Listen Address in Service Settings.
  • Rarely 'app' container fails to start because of "connection refused" to
