Create ECR repository

Our first step will be to create a repository in ECR, this is where we later will store our container image once it’s been built.

Let’s create our repository:

$ aws ecr create-repository --repository-name apprunnerworkshop-app
    "repository": {
        "repositoryUri": "", 
        "imageScanningConfiguration": {
            "scanOnPush": false
        "encryptionConfiguration": {
            "encryptionType": "AES256"
        "registryId": "1234567891012", 
        "imageTagMutability": "MUTABLE", 
        "repositoryArn": "arn:aws:ecr:eu-west-1:1234567891012:repository/apprunnerworkshop-app", 
        "repositoryName": "apprunnerworkshop-app", 
        "createdAt": 1623314531.0

We are interested in using the repositoryUri later, so that we can tag and push images to the repository, let’s go ahead and store that as an environment variable for easy access later on.

$ export ECR_REPOSITORY_URI=$(aws ecr describe-repositories --repository-names apprunnerworkshop-app --query 'repositories[?repositoryName==`apprunnerworkshop-app`].repositoryUri' --output text)

Great, we have created our repository, let’s move on to the next step, which is building our image and pushing it to the registry.
