Docker is being deployed with ansible using the offical mattermost-team-edition docker image

Env has  
`MM_SQLSETTINGS_DATASOURCE=postgres://mattermost:xyz@tcp(mattermost-db:5432)/mattermost?sslmode=disable`

Database is official postgres docker image with same username and password as set in `MM_SQLSETTINGS_DATASOURCE`

Within mattermost container I can ping mattermost-db but for whatever reason the mattermost gorm layer leeps returning

```

```

netcat smoke test from the mattermost container into the mattermost-db 5432 also works returning  
`EhSFATALVFATALC28P01Mpassword authentication failed for user "username"Fauth.cL330Rauth_failed/`  
Showing that the app can connect to the db
