The Docker Image contains the aws-cli and kubectl. It is used to update the AWS ECR credentials periodically in a kubernetes cluster.
You need to set your credentials in the aws-secrets.yml. Also you need to set your AWS_ACCOUNT, AWS_REGION and NAMESPACES in ecr-cron.yml. Afterwords run:
aws.sh
Afterwords you should be able to see the cron job with:
kubectl get cronjobs -n infrastructure
