+
+## 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:
+
+--8<-- "premix-cta.md"
+
+```yaml
+version: '3'
+
+services:
+
+    db:
+      image: mattermost/mattermost-prod-db
+      env_file: /var/data/config/mattermost/mattermost.env

+          sleep $$BACKUP_FREQUENCY
+        done
