## What this PR does Pre-pulls every image referenced by `packages/system/kubeovn`, `packages/system/linstor`, and `packages/system/cert-manager` onto every node before those HelmReleases install. Cluster-member workloads (OVN raft, LINSTOR, cert-manager webhook) fail when replicas start at different times due to per-node image-pull stagger; pre-pulling means all replicas start with images already cached. ## Mechanics Renders each chart with `helm template`, then runs a `yq` filter that walks every PodSpec-shaped object and emits the images of each container — scoping the output to images the kubelet actually pulls (skips configmap fields and CRD examples that happen to contain an `image:` key). Each render is staged through a tmp file so a helm-template failure trips `set -e` cleanly (cozytest.sh runs `@test` bodies under `/bin/sh`, which is dash on Ubuntu CI — no `pipefail`). The pre-pull DaemonSet itself is the hard part: distroless images (cert-manager and friends) ship no shell and no `/bin/sleep`, so the obvious `command: ["sleep", "infinity"]` fails with `exec: ENOENT`. The script stages a statically-linked `busybox:musl` into a shared `emptyDir` from an initContainer; every prepull container then execs `/shared/sleep` regardless of what the image itself ships. The glibc `busybox` tag is unusable — it needs `/lib64/ld-linux-x86-64.so.2` which distroless lacks. ## Origin Lifted from #2619 — squash of `test(e2e): pre-pull cert-manager images` → POSIX rewrite → cert-manager removal (failed on distroless) → reintroduction with the busybox helper that solves the distroless problem. Final state only — the four iterative commits aren't review-friendly individually. ## Verification - `sh -n hack/e2e-prepull-images.sh` clean - All chart-referenced images held Ready under the DaemonSet on local kind v1.33.1 single-node ### Release note ```release-note NONE ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Tests** * Improved end-to-end test reliability for platform image pre-pulling by rendering charts separately and consolidating extracted images. * Simplified and consolidated readiness waits during tenant configuration for more robust application readiness checks. * **Chores** * Enhanced image pre-pulling to reliably handle distroless images using a staged helper binary and shared volume approach. <!-- review_stack_entry_start --> [](https://app.coderabbit.ai/change-stack/cozystack/cozystack/pull/2724?utm_source=github_walkthrough&utm_medium=github&utm_campaign=change_stack) <!-- review_stack_entry_end --> <!-- end of auto-generated comment: release notes by coderabbit.ai -->
