Pull request overview
This PR extends the API proxy sidecar and CLI to support GitHub Enterprise Cloud/Server Copilot routing by deriving the correct Copilot API upstream from GITHUB_SERVER_URL, with a manual override via COPILOT_API_TARGET / --copilot-api-target. It also adds documentation and tests around the new behavior.
Changes:
- Add Copilot API target auto-derivation in
containers/api-proxy/server.js(GHEC*.ghe.com, GHES custom domains, github.com default) and unit tests. - Thread
copilotApiTargetthrough wrapper configuration and docker-compose generation, and add CLI warnings/tests for allowlist coverage. - Add enterprise setup documentation and link it from the README; tighten api-proxy log sanitization; adjust some integration tests’ curl flags.

* These tests now use `curl -sS` without `--fail`/`-f`. Without `--fail`, curl exits 0 even on HTTP 403/404, which can make the test pass even if the request was blocked by Squid (403 TCP_DENIED) or otherwise errored. Use `-fsS` (or at least add `--fail`) so `toSucceed()` actually asserts the request was allowed.

This test now uses curl -sS without --fail/-f. curl will return exit code 0 for many HTTP error status codes unless --fail is set, which weakens the assertion that the request was actually allowed. Prefer -fsS (or add --fail) here.

emitApiProxyTargetWarnings validates Copilot against config.copilotApiTarget ?? DEFAULT_COPILOT_API_TARGET, but the api-proxy can auto-derive a non-default Copilot target from GITHUB_SERVER_URL (e.g., api.<tenant>.ghe.com or api.enterprise.githubcopilot.com). In those cases users still must allowlist the derived host, but this warning path will not catch missing domains. Consider deriving the effective Copilot target here as well (using the same logic as the sidecar) when copilotApiTarget is unset.

The examples set GITHUB_TOKEN for Copilot, but AWF’s api-proxy/CLI expects the Copilot credential in COPILOT_GITHUB_TOKEN (the value held in the sidecar and replaced with a placeholder in the agent). As written, users can follow this guide and still get “API proxy enabled but no API keys found” / Copilot proxy not started. Update the doc examples to use COPILOT_GITHUB_TOKEN (and align the referenced secret names accordingly).

This PR introduces DEFAULT_COPILOT_API_TARGET/copilotApiTarget, but the CLI currently passes options.copilotApiTarget/COPILOT_API_TARGET through as-is (no hostname-only validation). The api-proxy treats this value as a bare hostname (builds https://${targetHost} and passes it to https.request({ hostname })), so inputs containing a scheme/path/port (e.g. https://... or host:8443) will break at runtime. Add explicit validation/normalization for Copilot (and ideally the other *-api-target flags) to reject invalid values with a clear error message.

${{ github.server_url_hostname }} is not a standard GitHub Actions context value, and this repo doesn’t define it elsewhere. Using it in workflow snippets will fail expression evaluation. Prefer using the provided GITHUB_SERVER_URL env var and extracting the hostname in the run: script (or document a supported alternative) before passing it to --allow-domains.

These log expectations don’t match current api-proxy output: server.js logs GitHub Copilot proxy listening on port 10002 without including the derived target, and the startup log that includes api_targets.copilot doesn’t contain the string "Copilot proxy". As a result, grep "Copilot proxy" won’t show the expected (target: ...) line. Update the docs (or include target in the Copilot server_start log).
