- Around line 16-19: Update the “Test” phase documentation in the workflow’s
Phase breakdown to describe ArgoCD synchronization validation via
gcp-hcp-verify-argocd-sync and its execution of Ginkgo tests; remove the
placeholder wording while leaving the Pre and Post phase descriptions unchanged.
In
`@ci-operator/step-registry/gcp-hcp/tf-provision/gcp-hcp-tf-provision-commands.sh`:
- Around line 27-48: Update the curl invocation inside tfc_api_call to include
both a connection timeout and an overall request timeout, ensuring each
Terraform Cloud API attempt returns promptly so the existing retry loop can
execute.
- Around line 197-198: Update both Terraform retry loops: in
ci-operator/step-registry/gcp-hcp/tf-provision/gcp-hcp-tf-provision-commands.sh
lines 197-198 and
ci-operator/step-registry/gcp-hcp/tf-deprovision/gcp-hcp-tf-deprovision-commands.sh
lines 120-121, execute each Terraform command within an if condition before
assigning its exit status. Preserve the captured output and ensure failures
bypass errexit so the existing retry logic can run.
In
`@ci-operator/step-registry/gcp-hcp/verify-argocd-sync/gcp-hcp-verify-argocd-sync-commands.sh`:
- Around line 45-60: Update the management-cluster kubeconfig flow around gcloud
container clusters get-credentials so the intended
unavailable-management-cluster state does not abort the script under set -e,
while unexpected authentication or configuration failures still propagate. Only
run kubectl config view and export MC_KUBECONFIG after kubeconfig creation
succeeds; always preserve REGION_KUBECONFIG and allow /usr/bin/test-e2e to run
when management validation is unavailable.
- Around line 33-39: Update the region kubeconfig flow around `gcloud container
clusters get-credentials` to read and use a distinct `region-cluster-name`
Terraform output, while retaining `mc-cluster-name` for management-cluster
lookups. Ensure the provision/export step writes the region cluster name to the
shared directory and the `${REGION_PROJECT}` lookup uses that value.

Implements GCP-557: Replace placeholder ArgoCD validation step with real Ginkgo v2 tests Changes: - ci-operator config: Add gcp-hcp-e2e-tests image build from Dockerfile.e2e - verify-argocd-sync commands.sh: Replace placeholder with full implementation - Authenticate with WIF credential from hypershift-gcp-wif-auth step - Generate region and MC cluster kubeconfigs via gcloud CLI - Run Ginkgo v2 test binary with JUnit output - Export REGION_KUBECONFIG and MC_KUBECONFIG to test environment - verify-argocd-sync ref.yaml: Update step configuration - Use gcp-hcp-e2e-tests image (from gcp-hcp-infra repo) - Increase resources: 500m CPU, 1Gi memory (for Go client libraries) - Increase timeout: 60min (accommodates 30min sync + retries + setup) - Update documentation with dependencies and environment variables Architecture: - Bash wrapper: WIF auth + kubeconfig generation via gcloud CLI - Ginkgo test binary: Pure Go validation using controller-runtime/client-go - No gcloud SDK in test image (only in wrapper script) - JUnit XML output to ARTIFACT_DIR for Prow test grid Test flow: 1. Wait for ArgoCD namespace (20min timeout) 2. Wait for ArgoCD server deployment ready (20min timeout) 3. Poll Applications for Synced status (30min timeout, configurable) 4. Auto-retry stuck apps every 2 minutes 5. Optional MC cluster validation (skips if MC_KUBECONFIG not set) Related: openshift-online/gcp-hcp-infra commit 29b7ce7f
The images section requires an 'items' key for the list of images. This matches the format used in other ci-operator configs like openshift/hypershift.

Running make jobs with increased Docker memory (8GB) to regenerate Prow job configurations after adding gcp-hcp-e2e-tests image to ci-operator config. Changes: - Update decoration_config to use sparse checkout for Dockerfile.e2e - Move github-credentials from volumes to oauth_token_secret in decoration - Remove redundant github-credentials volume definitions Resolves generated-config CI check failure.

…_token_secret The previous commit moved github-credentials to decoration_config oauth_token_secret but left the volumeMount references, causing: 'volumeMount named "github-credentials-openshift-ci-robot-private-git-cloner" is undefined' Removed all volumeMount entries for github-credentials since oauth_token_secret in decoration_config provides credentials without explicit volume mounts.
Cluster endpoints can expose internal hostnames/IPs. Remove from diagnostic logging per CodeRabbit security finding.

1. Add check-cleanup-image step as first pre step to validate the upi-installer image has all required binaries (jq, gcloud, curl, kubectl/oc) before spending 40 min on provision. Will fail fast in ~10 seconds if anything is missing. 2. Fix cleanup-infrastructure to use oc as kubectl fallback since upi-installer has oc but not kubectl. TODO: Remove check-cleanup-image step after validation.

…lete
The TFC API rejects workspace deletion when it manages resources (403),
and pushing empty state via API fails with lineage/lock conflicts.
Fix: install terraform CLI, create minimal cloud backend config, and use
'terraform state rm' at the module level to clear all resources in ~3s.
Then safe-delete the empty workspace.
Tested locally against platform-e2e-be2f7703 (466 resources):
- terraform state rm module.{customer_project,management_cluster,region}: 3s
- safe-delete: HTTP 204 success
Also handles:
- Force-unlock if workspace locked from previous run
- Fallback to per-resource rm if top-level data sources remain
- Correct terraform version (1.15.8) to match workspace constraint

Fix TFC state rm to include data.terraform_remote_state.* sources in the bulk rm call. Previous run left 4 data sources in state, causing safe-delete to return 409. 3.

Summary
Implements the E2E test pipeline for GCP HCP infrastructure. The pipeline provisions ephemeral infrastructure via Terraform Cloud, validates ArgoCD application sync on both region and management clusters using Ginkgo v2 tests, and cleans up all resources afterward.
Status: Pipeline passing — all 6 Ginkgo specs pass (19 region apps, 14 MC apps synced), terraform destroy succeeds cleanly.
Pipeline Workflow
What This PR Adds
New Step Registry Steps
gcp-hcp-generate-kubeconfigs— Generates static kubeconfigs using Connect Gateway (connectgateway.googleapis.com). Uses embedded access tokens from WIF (1-hour validity, sufficient for CI). MC clusters use the region project number for fleet membership lookup.gcp-hcp-verify-argocd-sync— Runs the Ginkgo v2 test binary fromgcp-hcp-infra/test/. Validates ArgoCD namespace creation, server deployment readiness, and full application sync on both region and management clusters. Configurable sync timeouts (default 45m) via env vars. 90m step timeout with 85m Ginkgo suite timeout.gcp-hcp-pre-destroy-cleanup— Runs before terraform destroy to remove GCP resources that ArgoCD-deployed apps create and that block destroy:best_effort: true— cleanup failures don't block the jobModified Steps
gcp-hcp-tf-provision— Added Firestore provider bug workaround (hashicorp/terraform-provider-google#22533): detects 409 "Database already exists" errors from the read-after-write consistency bug and imports orphaned Firestore databases before retrying.gcp-hcp-tf-deprovision— No changes to the script itself; the pre-destroy-cleanup step now runs before it in the workflow.CI Operator Config

Connect Gateway for Cluster Access
Uses Connect Gateway (
{region}-connectgateway.googleapis.com) instead of direct GKE master endpoints. This allows accessing private GKE clusters without exposing public master endpoints. Clusters are already enrolled in fleet — no additional infrastructure changes needed.Pre-Destroy Cleanup vs. Terraform
ArgoCD-deployed apps create GCP resources (NEGs, DNS records, Gateway LB infrastructure) that Terraform doesn't manage. These must be cleaned up before
terraform destroyor the destroy fails with "network in use" / "zone not empty" errors. The cleanup step handles this surgically — only removing resources that block destroy, not resources that Terraform manages.Timeouts
Initial conservative timeouts to establish a baseline. Can be scaled back once we know what stable looks like:
