Generate a secret token from Kubernetes for Nexus.
Code Block kubectl create secret docker-registry --dry-run=true docker-nexus \ --docker-server=url\ --docker-username=admin \ --docker-password=password \ --docker-email=email\ --output="jsonpath={.data.\.dockerconfigjson}"Copy the generated secret token.
