Multiple docker containers managed by Docker Compose

• Connect 2 compose images in docker | Docker

• Initially, I had to set up the repo

python3 -m venv .venv

• And then, looks like on each start up source .venv/bin/activate python -m pip install --upgrade pip

• And then create Dockerfiles for the ElasticMQ container, ...

• Use the following to up and build:

docker-compose up --build

• Which will display something like:

elasticmq_1  | 22:07:30.046 [main] INFO  org.elasticmq.server.Main$ - === ElasticMQ server (0.15.8) started in 1727 ms ===

• You can issue the following command to check on the containers from the root of the repo:

(.venv) allendavidsnook@Lamia hellocompose % docker-compose ps
          Name                        Command               State    Ports
----------------------------------------------------------------------------
hellocompose_elasticmq_1   java -Djava.net.preferIPv4 ...   Up      9324/tcp

• And the following to tear it all down:

(.venv) allendavidsnook@Lamia hellocompose % docker-compose down
Stopping hellocompose_elasticmq_1 ... done
Removing hellocompose_elasticmq_1 ... done
Removing network hellocompose_default

• Remember that things like connection strings should reference the name of the container for the resource.
