Web UI for docker-compose

A simple sinatra app that helps selectively start/stop containers from the given docker-compose stack.

The main use case for the app is grouping of dockerized services. Consider docker-compose.yml with 20 containers (SOA!). Developers working on different parts of the whole system are going to need different subsets of the whole stack.

Such subsets can be configured using .dcui.yml file, saved in the same directory where docker-compose file lives.

Example .dcui.yml for docker-compose.yml containing services: mysql, redis, elasticsearch_dev, elasticsearch_test, kafka, traefik_dev, traefik_test:

system-testing:
  - mysql
  - redis
  - elasticsearch_test
  - traefik_test
development:
  - mysql
  - redis
  - elasticsearch_dev
  - kafka
  - traefik_dev

See the example directory

gem install dcui

Runtime configuration via env vars:

• DCUI_APP_DIR - path to directory with docker-compose.yml and .dcui.yml. Default: pwd
• DCUI_FILE_NAME - name of the docker-compose file. Default: docker-compose.yml
• DCUI_PORT - port on which the UI runs. Default: 4567

Start with command:

dcui

Sinatra runs in foreground. The UI is now present at http://localhost:4567

• start individual containers
• stop individual containers
• stop/start containers in batches
• containers groups (e.g. local development, local cucumber)
• make it look not so ugly
• considering adding inheritance to .dcui.yml sections
