Step1: Get the latest docker image from this link
https://github.com/kubernetes/autoscaler
Step2: Download the docker image to your local Mac/Laptop. The image address listed on the releases page Please note that image version should match with Kubernetes version.
$ docker pull k8s.gcr.io/autoscaling/cluster-autoscaler:v1.19.1
Step3: Retrieve an authentication token and authenticate your Docker client to your registry. Use the AWS CLI:
$ aws ecr get-login-password --region eu-west-1 | docker login --username AWS --password-stdin <account id>.dkr.ecr.eu-west-1.amazonaws.com
Step4: Create an ECR repo for Metrics Server if you don't have one
$ aws ecr create-repository --repository-name k8s.gcr.io/autoscaling/cluster-autoscaler --image-scanning-configuration scanOnPush=true
Step5: After the build completes, tag your image so, you can push the image to this repository:
$ docker tag k8s.gcr.io/autoscaling/cluster-autoscaler:v1.19.1 <account id>.dkr.ecr.eu-west-1.amazonaws.com/k8s.gcr.io/autoscaling/cluster-autoscaler:v1.19.1
Step6: Run the following command to push this image to your newly created AWS repository:
$ docker push <account id>.dkr.ecr.eu-west-1.amazonaws.com/k8s.gcr.io/autoscaling/cluster-autoscaler:v1.19.1
