[Travis CI] docker image 빌드하여 dockerhub에 푸시작업 자동화하기

1. 프로젝트 루트폴더에 .travis.yml 파일을 생성한다.

2. .travis.yml 파일을 다음과 같이 작성한다.

	dist: trusty
	env:
	global:
	- DOCKER_USER="USERNAME"
	- DOCKER_PASS="PASSWORD"
	jobs:
	include:
	- stage: build safe-place images and push to dockerhub repository
	script:
	- echo "$DOCKER_PASS" | docker login -u "$DOCKER_USER" --password-stdin
	- docker build --tag kimwithglasses/safe-place-db:0.0.1 . && docker push kimwithglasses/safe-place-db
	- cd SafePlaceAPI && ./gradlew bootJar && docker build --tag kimwithglasses/safe-place-api:0.0.1
	. && docker push kimwithglasses/safe-place-api

• 로그인
• echo "$DOCKER_PASS" | docker login -u "$DOCKER_USER" --password-stdin  
• 현재 경로에 있는 DOCKERFILE build & push
• docker build --tag kimwithglasses/safe-place-db:0.0.1 . && docker push kimwithglasses/safe-place-db
• 경로 이동하여 gradle project build & push
• cd SafePlaceAPI && ./gradlew bootJar && docker build --tag kimwithglasses/safe-place-api:0.0.1 .  && docker push kimwithglasses/safe-place-api

3. 위의 경우는 password가 노출되어있기 때문에 암호화를 진행한다.

1. .travis.yml이 있는 경로로 이동
2. DOCKER_PASS 변수 암호화

• travis encrypt DOCKER_PASS="password" --add --com

4. 최종 완성된 .travis.yml 파일의 모습은 다음과같다.

	dist: trusty
	env:
	global:
	- DOCKER_USER=kimwithglasses
	- secure: AEEIHpGihnGMPyUUf5LosnuoXJiJlRiAhiPpSiXmw+tG2TQRj+O92gnmOsZ8mnrOs54WbE7ECorBgDSCbdKFAEL6MFfqwIlXQgrucvAYaybk9Oo2eO6Gv9NQPKPgQS6O4ZHacEWncZz9ektk8XQsMjdvnvVgSTL8QYo9mQIqoqB1hZYrRRdKaXOqjnuK/zjryqS2xwtbHyJh3KNLPt3qzUqPYI/eKqa7QgiK5uLJp2uTPy4/ipbEuvxYZzZsF44sRBiqvQhsQ7Xo1xuv3bGGmhRS+NO8mbJF6egZZear+QzaRGqx5G3PZ7CY1sTpSkzwE56h0jXy2BRciClItJ4CNXdH4wf2MK9qsyY5lwY6u2+A4lHnz170UCs/G2tCY6qEg5mkVcf9XOd2D2cJaHW+eyHhta0SjRLOsOEYk2K1qS3FBqm1LGTHqNSx5VWQDVk78Wg7fu7M9TZpgjx0YTpjhaeEQKnmh+3VGn44CEdzn0lCOjPFDUujlidZOZ1dYcRAPSgh7JcGQqNuHCBQVr5LCJkeNtIalwvzPC96oQzLkl7tqYCJc+yIvTng9jPlHzS6zqV8lI6twOkHxvXxo9GvmLaT7Vm6zjfJqCLdWhsX8Sl4DBiHPQb8cQ/576EtznKYYrr6LuX+QVWwsW+ns09LqnmOTtxzNIz7BK3O/Kbr1ts=
