Cli that restarts you docker compose services when a file inside one of its volumes changes.
Useful for faster developement with containers that expose behaviour based on mounted files.
- graphql api restart when schema file changes
- graphql api mocks based on schema file (like this one)
- Every container that generates code and exposes a server based on a config file
- Nodejs container restarts when the src folder changes, recompiling with tsc
- Mongoke restarts when config schema changes
pip3 install compose-watcher # then you can watch for changes compose-watcher -f docker-compose.yml
Use the directories you want to track as service volumes.
Also consider using
init: true in the compose service definition for faster killing of processes.
To not stop the
docker-compose commands on other terminals there should be always a running container (this is a strange fact about docker-compose).
version: '3' services: api: build: . command: sh -c 'tsc --incremental && node index.js' volumes: - ./src:/src
compose-watcher to watch changes.
compose-watcher -f docker-compose.yml --timeout 5

How it works
After running the
compose-watcher command all the volumes mounted on every service are tracked for change, when a change happens the service where the volume is mounted is restarted toghether with the services in the
depends_on filed. Then the other services that have the restarted service as a dependency in
depends_on are restarted too.
