Docker Compose (v3)

Background

Some people (me included) use the full advantages of docker, without using a ready-made streama-only docker file. Instead, we use docker (or rather, docker-compose) to line up all the required components for the running system, and let them communicate with each other, as well as mount the relevant files and folders as volumes so that they are persisted.

In this section, I will give you a pretty solid Docker-Compose file and some instructions for getting it running with streama.

The folder structure

As usual, I like to start with /data/streama. In there, I have the following files:

/data/streama

-rw-r--r--  docker-compose.yml
-rw-r--r--  application.yml
-rwxr--r--  streama-1.x.x.jar
lrwxrwxrwx  streama.jar -> streama-1.x.x.jar

Lets go over every file, one by one:

docker-compose.yml

Below you will find the full configuration for the docker-compose setup, including nginx, letsencrypt, mysql and smtp. Note how a lot of volumes are configured, both as files and folders. this is important to ensure that your dockerized data is actually persisted on your main VM.

For configuring the upload dirs, check the volumes /app/uploads and /app/local-files below.

docker-compose.yml

application.yml

This file holds the custom database configuration, as well as potential regex adjustments & mail-server adjustments. This is important to add here, because the docker-compose networking strategy will automatically add DNS entries for each docker-container, named after the respective config block. So in order for streama to speak with the mysql-database, you gotta use the docker-compose name (“db” in my example) instead of localhost. Same for mail.
