Logging from Docker
As suggested by @Robert in the comments the solution is to run bundle commands as part of the CMD in the docker-compose file:
The api service in my compose file thus becomes:
api: image: pt-rails env_file: .env.dev networks: - phototankswarm command: > sh -c ' bundle exec sidekiq -d -L /dev/stdout && bundle exec rails s -p 3000 -b 0.0.0.0 ' volumes: - /Users/martinhinge/Pictures/docker/phototank:/media/phototank - ./backend:/usr/src/app ports: - "3000:3000" depends_on: - db - redis - syslog logging: driver: syslog options: syslog-facility: "daemon" tag: "rails" syslog-address: "tcp://localhost:5514"
