It’s time to build our image, but before we can do that, we need to retrieve login credentials for our local container engine, so that we can push the image
$ export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query 'Account' --output text)
$ export AWS_REGION=[AWS_REGION] # Change this to the region you are using, for example eu-west-1
$ aws ecr get-login-password --region $AWS_REGION | docker login --username AWS --password-stdin $AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com
Login Succeeded
The Dockerfile contains the instructions for assembling our container image. Ours is relatively
straight forward, and contains only a few directives for adding our source code to the image,
instructions for how to install dependencies, and finally what command to use for running the app.
Let’s have a look:
$ cat ~/environment/repostatus-gh-demo/Dockerfile
Let’s go ahead and build our app.
$ cd ~/environment/repostatus-gh-demo
$ docker build -t apprunnerworkshop-app:demo .
[build output omitted]
$ docker tag apprunnerworkshop-app:demo $ECR_REPOSITORY_URI:demo
$ docker push $ECR_REPOSITORY_URI:demo
We have now built our application image and pushed it to ECR. Let’s move on to setting up AWS App Runner.
