The command mentioned in step 1.d of section "Preparing cluster for mirroring"

Edit the .dockerconfigjson file to add your mirror registry and authentication credentials and save it as a new file:

{"auths":{"<local_registry>": {"auth": "<credentials>","email": "you@example.com"}}},"<registry>:<port>/<namespace>/":{"auth":"<token>"}}}
    
When tried to parse the file with jq it fails as below:

# cat auth.json | jq
{
  "auths": {
    "example.local:8443": {
      "auth": "xxxxxxx",
      "email": "example@local.com"
    }
  }
}
parse error: Expected value before ',' at line 1, column 157

The correct syntax should be :

{"auths":{"<local_registry>": {"auth": "<credentials>","email": "you@example.com"}}}
