Add bastion host validation to ovn-kubernetes CI on AWS, Azure, and GCP.

  • New validate-bastionhost step checks SSH access, container runtime, and reachability to cluster nodes. The same ref is used on all three platforms.
  • New OVN bastion workflows provision a bastion after IPI install, run that validation, then the existing OVN e2e suite.
  • e2e-aws-ovn, e2e-azure-ovn, and e2e-gcp-ovn now use these workflows. Shared non-bastion workflows are unchanged.
  • Azure and GCP bastion provision scripts are updated so they work with standard IPI (no BYO network).

Summary by CodeRabbit

This PR adds AWS, Azure, and GCP OVN-Kubernetes CI workflows with bastion host provisioning and validation.

  • The OVN e2e jobs now use the new bastion workflows.
  • Bastion validation checks SSH access, container runtime support, node connectivity, and system information.
  • Azure provisioning selects non-overlapping CIDR ranges.
  • GCP provisioning improves VPC and subnet detection for BYO-VPC and standard IPI deployments.
  • Each workflow gathers diagnostics and deprovisions cloud resources after testing.

Walkthrough

The change adds AWS, Azure, and GCP OVN bastion workflows. It adds bastion validation, improves Azure and GCP network discovery, assigns workflow ownership, and routes existing OVN jobs through the new workflows.

Changes

OVN bastion E2E

Layer / File(s) Summary
Provider bastion provisioning
ci-operator/step-registry/azure/provision/bastionhost/azure-provision-bastionhost-commands.sh, ci-operator/step-registry/gcp/provision/bastionhost/gcp-provision-bastionhost-commands.sh
Azure selects available IPv4 and IPv6 CIDR ranges from VNET and subnet data. GCP resolves BYO-VPC and standard IPI network resources. Both scripts tighten shell quoting and comparisons.
Bastion validation step
ci-operator/step-registry/validate/bastionhost/*, ci-operator/step-registry/validate/OWNERS
The new validation step checks SSH access, key formats, container runtime operation, cluster-node reachability, and system information. It records validation results and logs.
Provider workflow definitions
ci-operator/step-registry/openshift/e2e/{aws,azure,gcp}/ovn-bastion/*
New provider workflows configure OVN installation, provision and validate bastions, run E2E tests, collect diagnostics, and deprovision resources. Workflow ownership metadata is included.
OVN job routing
ci-operator/config/openshift/ovn-kubernetes/openshift-ovn-kubernetes-main.yaml
The AWS, Azure, and GCP OVN jobs invoke their corresponding bastion workflows.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to d8455

This PR adds CI-only bastion validation workflows and updates Azure and GCP provisioning scripts. The remaining concerns are localized to shell-script conventions and step reuse confirmation; no actionable merge-blocking risk remains after normal checks and review.

23-41: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The retry helper reports failure when the final attempt succeeds.

Line 35 decides success from try, not from ret. When the attempt that sets try to max returns success, the loop exits with ret=0, but the function still returns 1. The new fallback call on line 309 passes retries as 3, so this edge case is reachable. Test ret instead.

🐛 Proposed fix
-    if [ ${try} -eq "${max}" ]; then
+    if [ "${ret}" != "0" ]; then
         echo "Never succeed or Timeout"
         return 1

Consider python3 and ipaddress for the CIDR math.

Lines 226 to 267 implement IP-to-integer conversion and overlap detection in Bash. The upi-installer image includes python3. A single python3 helper that uses ipaddress removes about 40 lines of bit manipulation, and it handles containment and IPv6 without extra code. This is optional and does not block the change.

Prefer the installer metadata over derived resource names.

Lines 102 and 103 rebuild ${infra_id}-network and ${infra_id}-master-subnet from the naming convention. The convention holds for current standard IPI installs, but it is not a contract. If it changes, this step fails with "Could not find network". The explicit error messages and the gcloud existence checks limit the damage, so this is a hardening suggestion only. Read the network and subnet from the installer metadata or from oc get infrastructure cluster when a kubeconfig is available.

Add an explicit timeout to the ref.

The script retries SSH up to 30 times with a 10-second delay, then repeats SSH calls in Checks 2 to 4. A bastion that never accepts connections can hold the step for more than 10 minutes and consume the job budget. Set a timeout on the ref to bound this validation step. Apply the same value to the AWS and Azure validation refs for consistency.

Quote the SSH target and use an array for options.

ShellCheck reports SC2086 on line 45. Word splitting on ${options} is intentional, but ${user}@${host} should be quoted. An options array removes the warning and keeps the intent explicit. Also declare options, output, and ret as local to avoid leaking state between calls.

Skip the remaining checks when SSH is not available.

Checks 2 to 4 run even when Check 1 failed after 30 attempts. Each check then repeats SSH attempts that cannot succeed. With ConnectTimeout=10 and the node ping loop, this adds several minutes to a job that has already failed. Guard the later checks with ${SSH_READY} and record them as SKIPPED.

Remove the redundant KUBECONFIG assignment.

Prow loads ${SHARED_DIR}/kubeconfig automatically for later steps. The assignment and export on lines 155 and 159 target the default path, so they add no behavior. Keep the -f check if you want to skip Check 4 when the cluster is not installed, and use ${KUBECONFIG} directly.

Based on learnings: "when a prior step writes the kubeconfig to ${SHARED_DIR}/kubeconfig, rely on Prow's automatic loading of that file for subsequent steps. Do not explicitly export KUBECONFIG or pass --kubeconfig unless a different kubeconfig path is required."

Verify Azure bastion cleanup.

The pre phase provisions a bastion with azure-provision-bastionhost at Line 11. The post phase has no matching Azure bastion teardown. If ipi-deprovision does not own that resource, every job can leak Azure resources after cluster deprovisioning. Add the matching cleanup step, or confirm that ipi-deprovision deletes the bastion.

Use the required shell safety baseline.

errexit is disabled, so unexpected failed commands can be ignored. Global set -x also violates the step-registry command-script policy. Use set -euo pipefail and leave tracing disabled. Keep expected validation failures inside conditionals or explicitly mark best-effort diagnostics with || true.

As per coding guidelines, step registry command scripts must “default to set -euo pipefail without -x.”

@arkadeepsen: This pull request references CORENET-7427 which is a valid jira issue.

Warning: The referenced jira issue has an invalid target version for the target branch this PR targets: expected the story to target the "5.1.0" version, but no target version was set.

Details

In response to this:

Add bastion host validation to ovn-kubernetes CI on AWS, Azure, and GCP.

Each platform gets a dedicated OVN bastion workflow that provisions a bastion, checks SSH access, then runs the existing OVN e2e suite. The e2e-aws-ovn, e2e-azure-ovn, and e2e-gcp-ovn jobs now use these workflows. Shared non-bastion workflows are unchanged.

Azure and GCP bastion provision scripts are updated to support the new validation steps.

Summary by CodeRabbit

This PR adds AWS, Azure, and GCP OVN-Kubernetes CI workflows with bastion host provisioning and validation.

  • The OVN e2e jobs now use the new bastion workflows.
  • Bastion validation checks SSH access, container runtime support, node connectivity, and system information.
  • Azure provisioning selects non-overlapping CIDR ranges.
  • GCP provisioning improves VPC and subnet detection for BYO-VPC and standard IPI deployments.
  • Each workflow gathers diagnostics and deprovisions cloud resources after testing.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the openshift-eng/jira-lifecycle-plugin repository.

Bound the worst-case duration of Check 1.

Each run_ssh_cmd call can make up to six SSH attempts with ConnectTimeout=10, and the loop repeats 30 times with a 10s sleep. If the bastion never answers, the check can run for over 30 minutes before it reports a failure. Reduce MAX_RETRIES, or set an explicit step timeout in validate-bastionhost-ref.yaml.

Pin the test image and account for restricted egress.

Remove the package-manager upgrade path.

The step container normally runs as a non-root UID with no package repositories configured. dnf upgrade, yum upgrade, and apt-get install then fail after a slow network attempt, and the script continues with the original client. Pin the step image to one that provides a modern OpenSSH client instead, and keep only the version log.

Use set -euo pipefail and remove the global set -x.

The script omits set -o errexit, so a failure in the key preparation block continues silently and later checks report confusing results. The script also enables tracing globally, and run_ssh_cmd must then disable and restore it on every call. Enable tracing only around the sections that need it.

If you add errexit, append || true to the diagnostic run_ssh_cmd calls on lines 391-404 and to the run_ssh_cmd calls used in conditionals that already tolerate failure.

Standard IPI does not provide BYO-VPC files. Discover the
installer-created network and control-plane subnet from metadata.json
after gcloud login, and document why the bastion stays on that subnet.

Verify SSH access, container runtime, and reachability to cluster nodes
after a bastion is provisioned. Include OpenSSH-to-PEM conversion and
legacy-algorithm fallbacks so the same ref works on AWS, Azure, and GCP.

Provision a bastion after IPI install, run shared bastion validation,
then the existing OVN e2e suite. Point e2e-aws-ovn, e2e-azure-ovn, and
e2e-gcp-ovn at the new workflows.

Do not explicitly export KUBECONFIG.

Keep the file-existence check, but remove the assignment and export. Prow automatically loads ${SHARED_DIR}/kubeconfig for later steps.

Based on learnings: when a prior step writes ${SHARED_DIR}/kubeconfig, rely on Prow’s automatic loading and do not explicitly export KUBECONFIG.
