ci: add retry and failure detection to GKE prerequisites downloads#84209jimdaga wants to merge 2 commits into
Conversation
The prerequisites step downloads CRDs and cert-manager manifests via curl without --fail or --retry. When the download silently fails (returns empty content), oc apply gets "no objects passed to apply" and the entire pre-phase fails. This accounts for ~2 of 22 failures in the e2e-v2-gke presubmit. Add --fail --retry 3 --retry-all-errors --retry-delay 5 to all curl commands via a CURL_CMD variable. With set -euo pipefail already in effect, --fail ensures curl returns non-zero on HTTP errors and pipefail propagates it through the pipe to oc apply.

WalkthroughThe prerequisite script adds ChangesPrerequisite manifest application
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The change makes prerequisite downloads fail fast and retry transient errors, while failed attempts may leave temporary manifest files on the runner. The PR is mergeable with owner awareness or follow-up to add cleanup on every exit path. Suggested reviewers: 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)

Full details: Stable And Deterministic Test NamesExplanation PASS. The pull request changes only the GKE prerequisites shell script. The diff adds download handling and manifest application logic, and it does not add or modify Ginkgo test declarations or test titles. Therefore, no unstable test name was introduced. Full details: Test Structure And QualityExplanation PASS: The pull request changes one Bash prerequisites script only. The exact diff adds Full details: Microshift Test CompatibilityExplanation PASS: The pull request changes one Bash prerequisite script only. The verified diff adds curl buffering and a shell helper; it adds no Ginkgo e2e tests or test declarations. Therefore the MicroShift test compatibility check is not applicable. Full details: Single Node Openshift (Sno) Test CompatibilityExplanation PASS: The PR changes only one shell script, Full details: Topology-Aware Scheduling CompatibilityExplanation PASS — The pull request changes only download and temporary-file handling in the GKE prerequisite shell script. The diff adds curl retry flags, Full details: Ote Binary Stdout ContractExplanation PASS — The pull request changes only a Bash GKE prerequisites script. It adds curl/download handling and shell output, but it does not modify an OTE binary or process-level Go/Ginkgo code such as main(), TestMain(), suite setup, or top-level initializers. The OTE JSON stdout contract is therefore not applicable. Full details: Ipv6 And Disconnected Network Test CompatibilityExplanation The PR changes only one shell prerequisites script. The cumulative diff adds no Ginkgo test files or constructs such as It(), Describe(), Context(), or When(). The new public curl downloads belong to CI setup, not a newly added Ginkgo e2e test, so this check is not applicable. Full details: No-Weak-CryptoExplanation PASS. The PR changes only the GKE prerequisite shell script to add curl retry flags and temporary-file handling. The added lines contain no MD5, SHA1, DES, 3DES, RC4, Blowfish, ECB, custom cryptography, or secret/token comparisons. Full details: Container-PrivilegesExplanation PASS: The PR changes only the prerequisites shell script. The diff adds curl retry flags, temporary-file handling, and replaces streaming Full details: No-Sensitive-Data-In-LogsExplanation PASS: The pull request adds no sensitive data to logged commands.

Address CodeRabbit feedback: --retry-all-errors with piped output can write duplicate data if a retry happens mid-stream. Download to a temp file first, then apply after curl succeeds. Extract a fetch_and_apply helper for the CRD downloads. Handle the cert-manager case separately since it needs a sed transformation between download and apply.
