Adds support to 3 environment variables: - WAREWULF_OCI_USERNAME: registry user username - WAREWULF_OCI_PASSWORD: registry user password - WAREWULF_OCI_NOHTTPS: disable tls requirements (for local registries) Note: This will default to ~/.docker/config.json for credentials and other docker configurations on the system when no options are specified.
