# MatterMost
|
|
|
|
Intro
|
|
|
|
|
|
|
|
Details
|
|
|
|
## Ingredients
|
|
|
|
1. [Docker swarm cluster](/ha-docker-swarm/design/) with [persistent shared storage](/ha-docker-swarm/shared-storage-ceph.md)
|
|
2. [Traefik](/ha-docker-swarm/traefik_public) configured per design
|
|
3. DNS entry for the hostname you intend to use, pointed to your [keepalived](ha-docker-swarm/keepalived/) IP
|
|
|
|
## Preparation
|
|
|
|
### Setup data locations
|
|
|
|
We'll need several directories to bind-mount into our container, so create them in /var/data/mattermost:
|
|
|
|
```
|
|
mkdir -p /var/data/mattermost/{cert,config,data,logs,plugins,database-dump}
|
|
mkdir -p /var/data/runtime/mattermost/database
|
|
```
|
|
|
|
### Prepare environment
|
|
|
|
Create mattermost.env, and populate with the following variables
|
|
```
|
|
POSTGRES_USER=mmuser
|
|
POSTGRES_PASSWORD=mmuser_password
|
|
POSTGRES_DB=mattermost
|
|
MM_USERNAME=mmuser
|
|
MM_PASSWORD=mmuser_password
|
|
MM_DBNAME=mattermost
|
|
```
|
|
|
|
Now create mattermost-backup.env, and populate with the following variables:
|
|
```
|
|
PGHOST=db
|
|
PGUSER=mmuser
|
|
PGPASSWORD=mmuser_password
|
|
BACKUP_NUM_KEEP=7
|
|
BACKUP_FREQUENCY=1d
|
|
```
|
|
|
|
### Setup Docker Swarm
|
|
|
|
Create a docker swarm config file in docker-compose syntax (v3), something like this:
|
|
|
|
!!! tip
|
|
I share (_with my [sponsors](https://github.com/sponsors/funkypenguin)_) a private "_premix_" git repository, which includes necessary docker-compose and env files for all published recipes. This means that sponsors can launch any recipe with just a ```git pull``` and a ```docker stack deploy``` 👍

|
|
!!! note
|
|
Setup unique static subnets for every stack you deploy. This avoids IP/gateway conflicts which can otherwise occur when you're creating/removing stacks a lot. See [my list](/reference/networks/) here.

## Serving
|
|
|
|
### Launch MatterMost stack
|
|
|
|
Launch the MatterMost stack by running ```docker stack deploy mattermost -c <path -to-docker-compose.yml>```
|
|
|
|
Log into your new instance at https://**YOUR-FQDN**, with user "root" and the password you specified in gitlab.env.

## Chef's Notes 📓
|
|
|
|
1. If you wanted to expose the Wekan UI directly, you could remove the oauth2_proxy from the design, and move the traefik_public-related labels directly to the wekan container. You'd also need to add the traefik_public network to the wekan container. |
