Description

Currently, the kubectl-plugin, and in particular the job submit command, relies exclusively on port-forwarding to localhost:8265, explicitly disabling support for the --address flag.

This is limiting in environments where:

• Port-forwarding is not feasible or desired.
• The Ray Dashboard is reachable at a stable, authenticated, or externally exposed URL.

Proposal
Enable a single flag on kubectl ray job submit:

--address: Ray Dashboard base URL (e.g., https://ray.example.com). When set, the plugin skips port-forwarding and passes the URL to ray job submit --address.

Behavior

• Default (no flag): port-forward to http://localhost:8265 (current behavior).
• With --address: no port-forward; use the provided URL.
• Validation: require a valid http(s) URL and normalize (trim trailing slash). Existing flags like --headers, --verify, etc., continue to pass through.

Benefits

• Supports direct submission to dashboards reachable via authenticated/public endpoints, load balancers, VPNs, tunnels, or service meshes.
• Simpler UX with a single flag and no new modes.
• Preserves backward compatibility.

Use case

Submit Ray jobs via a secure, reachable endpoint instead of relying solely on localhost port-forwarding.
