@Marvin Explain the following error message:

Failed to pull image "cnashunitedcenter/kubernetes:latest": failed to pull and unpack image "<http://docker.io/cnashunitedcenter/kubernetes:latest|docker.io/cnashunitedcenter/kubernetes:latest>": failed to resolve reference "<http://docker.io/cnashunitedcenter/kubernetes:latest|docker.io/cnashunitedcenter/kubernetes:latest>": pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed

This error message indicates a problem with accessing a Docker image from a repository. Here's a breakdown of the message: 1. Failed to pull image: The system attempted to download a Docker image specified by the name

cnashunitedcenter/kubernetes:latest

. 2. Failed to pull and unpack image: The process of downloading and preparing the image for use failed. 3. Failed to resolve reference: The system could not find or access the image reference

<http://docker.io/cnashunitedcenter/kubernetes:latest|docker.io/cnashunitedcenter/kubernetes:latest>

. 4. Pull access denied, repository does not exist or may require authorization: This suggests one of several potential issues: - The repository

cnashunitedcenter/kubernetes

might not exist on Docker Hub. - The repository exists but is private, and you do not have the necessary permissions or credentials to access it. - An authentication issue might be preventing access to the image. 5. Insufficient scope: authorization failed: This indicates a failure in the authentication process, likely due to missing or incorrect credentials. To resolve this issue, you can: - Verify that the repository name is correct. - Check if the repository is private and, if so, ensure you have the appropriate permissions and credentials. - Log in to Docker Hub using

docker login

with the correct credentials before attempting to pull the image.
