docker for mac では volume同期が遅い
docker-sync を用いて, 高速化する

prepare docker-sync

console

gem install docker-sync
brew install eugenmayer/dockersync/unox
brew install fswatch unison rsync

prepare docker files

以下 Files を作成
- Dockerfile
- docker-compose.yml
- docker-compose-dev.yml
- docker-sync.yml

Dockerfile

FROM centos:7.5.1804

WORKDIR /opt/django/

docker-compose.yml

version: '2'

services:
  django:
    build:
      context: ./
      dockerfile: ./Dockerfile
    working_dir: /opt/django/
    tty: true

docker-compose-dev.yml

version: '2'


volumes:
  django_syncs:
    external: true

services:
  django:
    volumes:
      - django_syncs:/opt/django/:nocopy

docker-sync.yml

version: '2'


options:
  compose-dev-file-path: 'docker-compose-dev.yml'

syncs:
  django_syncs:
    src: './'
    sync_strategy: 'unison'

start sync

console

docker-compose pull
docker-compose build --no-cache

# start sync and docker
#     docker-compose-dev.ymlにて, 設定を上書きしている
docker-sync start
docker-compose -f ./docker-compose.yml -f ./docker-compose-dev.yml up -d

# open console
docker-compose exec django /bin/bash

# stop
docker-sync stop
docker-compose down

# 以下では sync + up を一括で実行する
# 停止は ctrl + c
docker-sync-stack start

以上で同期が高速化する.
