+# refresh-credential
+
+`refresh-credential` is a service to refresh the AWS ECR authorization token because the authorization token is valid for 12 hours.
+
+## Development
+
+### Prepare a Kubernetes cluster
+
+```console
+# Set up kube context. The refresh-credential will connect to this Kubernetes cluster.
+kubectx [cluster-name]
+```
+
+### Prepare the AWS access/secret key pair
+
+```console
+aws configure
+```
+
+### Prepare the configuration
+
+```json
+{
+  "namespace": "default", # The namespace to find the Kubernetes secret name
+  "credentialSecret": "$HOME/.aws/credentials", # The secret name with AWS access/secret key pair
+  "region": "", # The AWS ECR registry region
+  "publicRegistry": false, # Indicate it's a private or public registry
+  "secretToUpdate": "" # The authorization token written to
+}
+```
+
+> **Note*
+> If you are using public a AWS ECR registry, the region name is either `us-east-1` or `us-west-2`. Reference to the [AWS ECR Public endpoints](https://docs.aws.amazon.com/general/latest/gr/ecr-public.html).
+
+### Running locally
+
+To run `refresh-credential` locally, the `example-config.json` can be used as follows:
+
+```console
+cd /workspace/gitpod/components/refresh-credential
+
+# Run refresh-credential to refresh the AWS ECR authorization token.
+go run . ecr example-config.json
+```
