An example of two containers running both a client and server, continuously sending ping and pong to each other.

docker-compose build 

Build service foo and bar.

docker-compose up -d 

Start service foo and bar.

docker-compose log -f foo 

Follow logs for service foo.

docker-compose log -f bar 

Follow logs for service bar.

docker-compose down 

Stop service foo and bar.

For convenience there are a couple of npm scripts that can be used:

npm run build 

Build service foo and bar.

npm run build -- --no-cache 

Build service without using cache.

npm run logs:foo 

Follow logs for service foo.

npm run logs:bar 

Follow logs for service bar.

npm run exec:foo 

Run a shell in foo.

npm run exec:bar 

Run a shell in bar.

npm up 

Start service foo and bar.

npm down 

Stop service foo and bar.

Environment variables can be added to a .env file.
