How to push multiple Dockerfile apps to AWS ECR at the same time

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
Code language: plaintext (plaintext)

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
Code language: Bash (bash)

Note how we use the for loop on line 4 above to loop through our directory names within the apps parent directory.
