Docker-sync example

version: '3.6'

services:
  php: 
    image: php
    build:
      context: services/php
      args:
        USER_ID: 1000

      - sync-name:/var/www
...

docker-sync.yml

version: '2'

options:
  verbose: true

syncs:
  sync-name:
    src: '.'
    sync_strategy: 'unison'
    sync_excludes: ['.idea', '.git', 'var/cache', 'var/log']

    watch_excludes: ['.*/.git', '.gitignore', 'var/cache', 'var/log']

Instructions

This is how I use docker-sync to get better performance with Symfony apps.
The performance increase is visible to me in both response time and test execution time.

1. Install docker-sync
2. Create docker-sync configuration in the project directory.
3. Map sync name as a volume in your docker-compose.yml
4. Start docker-sync with `docker-sync start -f` and check console for errors
5. Start docker-compose
6. Attach to the container and see your files there

If something breaks with the sync, there will be a bunch of files with `*conflict*` suffix. 
I usually just delete them and restart the sync with `CTRL+C (to break the process in the foreground)` 
and then `docker-sync stop && docker-sync clean`

Hope it works for you :)
