# Postgres settings
## Documentation for this image and available settings can be found on hub.docker.com
## https://hub.docker.com/_/postgres
## Please keep in mind this will create a superuser and it's recommended to use a less privileged
## user to connect to the database.
## A guide on how to change the database user to a nonsuperuser can be found in docs/creation-of-nonsuperuser.md

## Inside the container the uid and gid is 2000. The folder owner can be set with

## This will be 'mattermost-enterprise-edition' or 'mattermost-team-edition' based on the version of Mattermost you're installing.
MATTERMOST_IMAGE=mattermost-team-edition
MATTERMOST_IMAGE_TAG=latest

## Make Mattermost container readonly. This interferes with the regeneration of root.html inside the container. Only use
## it if you know what you're doing.
## See https://github.com/mattermost/docker/issues/18
MATTERMOST_CONTAINER_READONLY=false

## The app port is only relevant for using Mattermost without the nginx container as reverse proxy. This is not meant
## to be used with the internal HTTP server exposed but rather in case one wants to host several services on one host
## or for using it behind another existing reverse proxy.
APP_PORT=8065

## Configuration settings for Mattermost. Documentation on the variables and the settings itself can be found at
## https://docs.mattermost.com/administration/config-settings.html
## Keep in mind that variables set here will take precedence over the same setting in config.json. This includes
## the system console as well and settings set with env variables will be greyed out.

## Below one can find necessary settings to spin up the Mattermost container
MM_SQLSETTINGS_DRIVERNAME=postgres
MM_SQLSETTINGS_DATASOURCE=postgres://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}?sslmode=disable&connect_timeout=10

## Example settings (any additional setting added here also needs to be introduced in the docker-compose.yml)
