# Production Docker deployment for Mattermost
This project enables deployment of a Mattermost server in a multi-node production configuration using Docker.
[![Build Status](https://travis-ci.org/mattermost/mattermost-docker.svg?branch=master)](https://travis-ci.org/mattermost/mattermost-docker)
Notes:
- To install this Docker project on AWS Elastic Beanstalk please see [AWS Elastic Beanstalk Guide](./README.aws.md).
- To install Mattermost without Docker directly onto a Linux-based operating systems, please see [Admin Guide](https://docs.mattermost.com/guides/administrator.html#installing-mattermost).
## Installation using Docker Compose
The following instructions deploy Mattermost in a production configuration using multi-node Docker Compose set up.
### Requirements
* [docker]
* [docker-compose]
### Database
make sure to set the appropriate values for `MM_USERNAME`, `MM_PASSWORD` and `MM_DBNAME`
### 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.
3. Build and run mattermost
docker-compose up -d
4. Open `https://your.domain` with your web browser.
### Install without SSL certificate
1. Build and run mattermost
docker-compose up -d
3. Open `http://your.domain` with your web browser.
## Starting/Stopping
### Start
docker-compose start
### Stop
docker-compose stop
## 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](https://github.com/wal-e/wal-e) backup to S3.
```bash
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:
```bash
# 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.
## Customization
Customization can be done through environment variables.
### Mattermost App Image
* MM_USERNAME: database username, must be the same as one in DB image
* MM_PASSWORD: database password, must be the same as one in DB image
* MM_DBNAME: database name, must be the same as one in DB image
* DB_HOST: database host address
* DB_PORT_5432_TCP_PORT: database port
* MM_CONFIG: configuration file location. It can be used when config is mounted in a different location.
### Mattermost DB Image
* MM_USERNAME: database username, must be the same as on in App image
* MM_PASSWORD: database password, must be the same as on in App image
* MM_DBNAME: database name, must be the same as on in App image
* AWS_ACCESS_KEY_ID: aws access key, used for db backup
* AWS_SECRET_ACCESS_KEY: aws secret, used for db backup
* WALE_S3_PREFIX: aws s3 bucket name, used for db backup
* AWS_REGION: aws region, used for db backup
### Mattermost Web Image
* MATTERMOST_ENABLE_SSL: whether to enable SSL
* PLATFORM_PORT_80_TCP_PORT: port that Mattermost image is listening on
## 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](http://docs.mattermost.com/administration/upgrade.html) 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.
## More information
