I have a parent directory containing multiple sub-directories. Each of these child directories is a different application and contains a Dockerfile.
I want to build and push each image to AWS ECR.
The directory looks as follows:
├── apps
├── microservice1
├── app.js
├── Dockerfile
├── package.json
└── readiness.txt
├── frontend
├── Dockerfile
├── index.html
├── package.json
├── server.js
├── microservice2
├── app.py
├── bootstrap.sh
├── Dockerfile
└── requirements.txt
Notice there are 3 apps, each with their own Dockerfile, under the parent apps directory.
In the below code snippet, we have already set AWS_REGION to our desired region name.
If you have not done this, run export AWS_REGION='eu-west-1', or appropriate.
Also set the ACCOUNT_ID to your AWS’s account ID.
aws ecr get-login-password --region $AWS_REGION | docker login --username AWS --password-stdin $ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com
PROJECT_NAME=our-project-name
export APP_VERSION=1.0
for app in microservice1 microservice2 frontend; do
aws ecr describe-repositories --repository-name $PROJECT_NAME/$app >/dev/null 2>&1 || \
aws ecr create-repository --repository-name $PROJECT_NAME/$app >/dev/null
TARGET=$ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com/$PROJECT_NAME/$app:$APP_VERSION
docker build -t $TARGET apps/$app
docker push $TARGET
done
Note how we use the for loop on line 4 above to loop through our directory names within the apps parent directory.
