Requirements

Installation

Install with SSL certificate

Open docker-compose.yml and set MATTERMOST_ENABLE_SSL to true.
```
environment:
  - MATTERMOST_ENABLE_SSL=true
```
Put your SSL certificate as ./volumes/cert/cert.pem and the private key that has no password as ./volumes/cert/key-no-password.pem. If you don't have them you may generate a self-signed SSL certificate.
Build and run mattermost

docker-compose up -d
Open https://your.domain with your web browser.

Install without SSL certificate

Open docker-compose.yml and set MATTERMOST_ENABLE_SSL to false.
```
environment:
  - MATTERMOST_ENABLE_SSL=false
```
Build and run mattermost

docker-compose up -d
Open http://your.domain with your web browser.

Starting/Stopping

docker-compose start

Stop

docker-compose stop

Removing

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.

Upgrading to Team Edition 3.0.x from 2.x

You need to migrate your database before upgrading mattermost to 3.0.x from 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 database. Workaround: Restart the container.
