The helm_remote call in Tilt then tries helm pull from the live bitnami repo, which no longer lists 12.5.6, causing the Tiltfile to error and the devstack to never become ready. Switch postgresql.tiltfile to the bitnami archive branch on GitHub (archive-full-index) which preserves all historical chart versions. Update all three CI workflows (core-tests, full-stack-test, ux-tests) to: - add the repo under the name 'postgresql' (matching repo_name in the Tiltfile so the Tilt helm cache path aligns) - pre-pull via 'helm pull postgresql/postgresql --version 12.5.6' instead of the broken CDN curl Co-Authored-By: Claude Sonnet 4.6 (1M context) --- .github/workflows/core-tests.yml | 38 +++++---------------------- .github/workflows/full-stack-test.yml | 16 ++++------- .github/workflows/ux-tests.yml | 16 ++++------- devtools/tilt/postgresql.tiltfile | 2 +- 4 files changed, 18 insertions(+), 54 deletions(-) diff --git a/.github/workflows/core-tests.yml b/.github/workflows/core-tests.yml index 9c0804411a3..3d4445c3ccf 100644 --- a/.github/workflows/core-tests.yml +++ b/.github/workflows/core-tests.yml @@ -319,12 +319,7 @@ jobs: - name: Pre-pull Helm repos and charts (with retry) run: | retry() { local cmd="$*" attempt=1; until $cmd; do attempt=$((attempt+1)); [ $attempt -gt 3 ] && return 1; sleep $((attempt*5)); done; } - retry helm repo add bitnami https://charts.bitnami.com/bitnami 2>/dev/null || true - # bitnami retired charts.bitnami.com/bitnami — old versions like 12.5.6 - # are only available via the archive index on GitHub. - retry helm repo add bitnami-archive \ - https://raw.githubusercontent.com/bitnami/charts/archive-full-index/bitnami \ - 2>/dev/null || true + retry helm repo add postgresql https://raw.githubusercontent.com/bitnami/charts/archive-full-index/bitnami 2>/dev/null || true retry helm repo add argo https://argoproj.github.io/argo-helm 2>/dev/null || true retry helm repo add metaflow-tools https://outerbounds.github.io/metaflow-tools 2>/dev/null || true retry helm repo update || true @@ -337,13 +332,12 @@ jobs: retry helm pull argo/argo-workflows --version 0.45.2 --untar \ --destination "$HELM_CACHE/argo/0.45.2" || true - # PostgreSQL 12.5.6 — bitnami retired the chart CDN so pull from their - # GitHub archive index which still hosts the full back-catalogue. + # PostgreSQL 12.5.6 — bitnami retired both the helm repo index and + # the charts.bitnami.com CDN.

Also make the pre-test verification hard-fail (exit 1) if localbatch is unreachable from the minikube container — previously it logged the failure silently and then all 156 tests failed with cryptic errors instead of one clear step failure.

Without a pre-pull, each container startup hits Docker Hub (30-60s) before pip install (20s) and code-package download (10s) — 60-90s total per container. For graphs with multiple sequential container groups (simple-foreach has ~5, nested-branches has ~4+, simple_switch ~4), the per-test wall-clock time approaches or exceeds the 600 s scheduler timeout, causing ALL tests in those graphs to fail with "scheduler run timed out". Pre-caching python:3.10 in the CI runner's Docker daemon cuts container startup to ~30s, keeping every graph combination well within the 600 s budget. The k8s/argo fix (docker pull + minikube image load) already ran docker pull for those backends; the sfn/batch step does the same without the minikube load.
