Docker Hub Credential Secret

1. Generate a docker hub secret token dedicated to the cluster.

From your ogranization or your user account.

2. Create a JSON file

We will base64 encode it at the end.

dockerhub.json

{
  "auths": {
    "docker.io": {
        "username": "<your_username_here>",
        "password": "<your_token_here>",
    }
  }
}

3. Base64 encode the JSON file

cat dockerhub.json | base64

4. Create the secret in Kubernetes

dh-secret.yaml

```bash
apiVersion: v1
kind: Secret
metadata:
  name: dh-secret
  namespace: <your_namespace_here>
data:
  .dockerconfigjson: <base64_encoded_json_here>
type: kubernetes.io/dockerconfigjson

5. Apply the secret

kubectl apply -f dh-secret.yaml
