Docker in DockerのJenkins環境をdockerで構築

dockerで構築したjnekins内でdockerイメージを作成する

これができるとjenkinsでDockerイメージまで作成し、デプロイが簡単になります。

Dindイメージを使って作成してみます

ついでにdocker-composeで起動するように設定します

myjenkins:
	restart: always
	image: myjenkins:1.0
	ports: 
		- "8080:8080"
	volumes:
		- /data/jenkins:/var/lib/jenkins		# host volumeをマップング
		- /data/git:/opt/git:ro
	env_file:
		- ./.docker-compose.env
	environment:
		- JAVA_OPTS=-XX:MaxPermSize=256m
	privileged: true

myjenkins:

restart: always

image: myjenkins:1.0

volumes:

- /data/git:/opt/git:ro

env_file:

environment:
