The artifactapi web UI is open to anyone who can reach the host. Front it with Authentik SSO gated on akP-artifactapi-admin, while leaving the package-manager surfaces (/api/v1, /api/v2, /v2 docker registry, /terraform, /.well-known) untouched — dnf, containerd mirrors, buildah, terraform and CI publish steps cannot do a browser flow. - Add the oauth2-proxy ConfigMap, Deployment, Service and VMPodScrape. - Add the oauth-credentials VaultStaticSecret. - Point the api-route /ui rule at oauth2-proxy and add a /oauth2 rule; the catch-all / rule still goes straight to the api Service on both listeners. Requires terraform-authentik #34 applied and the Vault kv seed first. Reviewed-on: #456 Co-authored-by: unkin-agent <unkin-agent@unkin.net> Co-committed-by: unkin-agent <unkin-agent@unkin.net>

# SCOPE: this proxy fronts the artifactapi web UI ONLY. The HTTPRoute sends just
|
|
# /ui and /oauth2 here; every machine surface (/api/v1, /api/v2, /v2 docker
|
|
# registry, /terraform, /.well-known/terraform.json, /health, /version, /) goes
|
|
# straight to the api Service and is NOT authenticated. yum/dnf, containerd
|
|
# registry mirrors, docker/buildah, terraform init and Woodpecker publish steps
|
|
# cannot complete a browser OIDC flow, so they must never reach this container.
|
|
# Its only upstream is the ui Service -- there is deliberately no api upstream.
