（おまけ）ECR push用のMakefile

AWS_ACCOUNT_ID = 
REGION         = ap-northeast-1
ECR_REPO       = 
IMAGE_NAME     = 
TAG            = 

# ECRのURIを生成
ECR_URI = $(AWS_ACCOUNT_ID).dkr.ecr.$(REGION).amazonaws.com

build_and_push:
	aws ecr get-login-password --region $(REGION) | docker login --username AWS --password-stdin $(ECR_URI)
	docker build -t $(IMAGE_NAME):$(TAG) .
	docker tag $(IMAGE_NAME):$(TAG) $(ECR_URI)/$(ECR_REPO):$(TAG)
	docker push $(ECR_URI)/$(ECR_REPO):$(TAG)
