compose-watcher 1.1.5

compose-watcher

compose-watcher

Cli that restarts you docker compose services when a file inside one of its volumes changes To use with compiled languages place the compilation step in the command field.

Example usage

• graphql api restart when schema file changes
• Mongoke restarts when config schema changes
• Nodejs container restarts when the src folder changes, recompiling with tsc

Install

pip3 install compose-watcher

Usage

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 logs command, there should be always a running container

version: '3'

services:
  api:
    build: node_api
    command: sh -c 'tsc --incremental && node index.js'
    volumes:
      - ./node_api/src:/src

Then execute compose-watcher to watch changes

compose-watcher -f docker-compose.yml --timeout 5
