What this PR does

This adds a daily CI lane that installs the isp-hosted platform variant through the hosted installer variant. No lane ran either of them before. The PR, nightly and tag lanes all install isp-full on Talos, where Cozystack brings its own CNI and storage, and that is how #3376 shipped unnoticed.

What isp-hosted changes is what it leaves to the host. The system bundle swaps kube-ovn and Cilium for a noop networking Package and drops multus, LINSTOR, MetalLB, cozy-proxy, snapshot-controller and the rest of the shared data-plane set. The iaas bundle refuses to render. Migrations are not a difference, isp-full enables them too.

So the lane runs on kind. kindnet, kube-proxy and local-path come from the cluster, and there is no Cilium, no LINSTOR and no replicated or local StorageClass. It installs the latest GHCR nightly instead of building anything, at 05:00 UTC after the nightly mirror publishes, and on workflow_dispatch. There is no pull request trigger, because a run would install the nightly images and not the PR's.

A run passes when every HelmRelease is Ready, cozystack-platform and tenant-root included. It also checks that the platform emitted the noop networking Package and none of LINSTOR, MetalLB, multus or KubeVirt, and that the cluster has no Cilium CRD and no replicated or local class.

The lane reuses the e2e sandbox container for tooling and collect-report, attached to the kind network. hack/isp-hosted-lane_test.bats pins the wiring: the Package selects isp-hosted, the install uses variant=hosted, the kind DNS domain matches networking.clusterDomain, and kind is pinned by checksum and digest. Six of its seven tests were red before the implementation existed.

hack/sandbox-runner-headroom.bats gets a named exemption. That check treats any workflow touching packages/core/testing as a lane that boots the QEMU guests, and this one boots none. The exemption is checked after the job match, and removing it turns the test red again.

The pins come from the kind v0.32.0 release: the binary sha256 50030de2… from its kind-linux-amd64.sha256sum, and kindest/node:v1.33.12@sha256:3f5c8443… from its release notes. v1.33.12 is the Kubernetes version the Talos lanes use, so the variant is the only thing that differs. All three are plain env values in the workflow, where a Renovate custom manager can match them.

Real runs

The first real run on this branch, 36961209755, went red on tenant-root:

tenant-root  False  Helm install failed for release tenant-root/tenant-root with chart [email protected]+629b61300902: unable to build kubernetes objects from release manifest: resource mapping not found for name: "allow-external-communication" namespace: "tenant-root" from "": no matches for kind "CiliumNetworkPolicy" in version "cilium.io/v2"

This is #3387 reproduced live: packages/apps/tenant renders Cilium policies on a cluster without Cilium. The other releases went Ready, except cozystack-basics, which was still in an upgrade at the last listing. The fix landed in #4710.

The run after it, 37089699259, is green on the first attempt. It installed nightly 0.0.0-nightly.20261003.37089458387.1, built from 309875a, which contains #4710. All four install tests passed, tenant-root included, with no cilium.io CRD on the cluster. The install took about 9 minutes.

Notes

The OpenAPI suite is not run. Its "Test kinds" case needs an Ingress application, and kind has no LoadBalancer, so it would fail for a reason unrelated to the variant.

The red run's job log is 347 MB. cozytest's live trace prints the whole HelmRelease snapshot JSON from cozy_wait_all_helmreleases_ready on every 2-second poll, and gh run view --log breaks at that size. The isp-full lanes use the same helper, and it is tracked separately.

The red run spent about 31 minutes in install, most of it waiting out the 30-minute gate; the green one took about 9 minutes on oracle-vm-24cpu-96gb-x86-64. Moving to a smaller runner needs a measured run, so it is a follow-up and not part of this PR.

Follow-ups from review, none blocking:

  • No vars.NIGHTLY_ENABLED gate, so with the nightly switched off the lane keeps testing a stale nightly tag. A workflow_run trigger on a successful mirror would fix that too.
  • The Package endpoint cozy-hosted-control-plane has to agree with KIND_CLUSTER: cozy-hosted, and no test checks that yet.
  • The operator registration check greps a Go literal in cmd/cozystack-operator/main.go, so reformatting that table breaks it.
  • The oras download has no checksum check, same as in nightly.yaml.
  • cozytest stops at the first failing test, so on a red install the "no Cilium" check never runs. Running it before the install would keep that evidence in red runs.

Closes #3390

Not a UI change.

Downstream repositories

The diff adds CI files, test files and one new make target. Nothing under hack/ is moved or renamed and no existing target changes, so the ccp trigger does not apply.

Merge Risk: 🔵 Low · up to 8a27b

The lane’s remaining risks are limited to missing report-failure visibility and incomplete test-count verification, rather than product-runtime behavior. Addressing them would improve confidence in its CI results.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 8a27b

The lane limits repository and registry permissions, excludes pull-request triggers, pins cluster dependencies, and separates preparation retries from installation failures. No introduced security vulnerability was established. Residual uncertainty concerns runner isolation and disposal after interrupted or failed cleanup.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The evidenced execution scope includes the kind cluster and potentially its runner host, not merely Kubernetes namespaces: the sandbox is privileged and the workflow performs sudo host operations. Compromise of the executed harness or nightly sandbox image could therefore affect the runner. The inspected configuration provides read-only repository and package authority, with no production credential or deployment target shown; actual host isolation remains unverified.

Trust Boundaries and Controls

  • inferred — The privileged execution boundary trusts the triggering repository revision for the harness and the nightly package publisher for the installed tree and sandbox image. The explicit trigger set does not expose this lane directly to fork pull requests. Digest resolution controls artifact consistency, while publisher compromise and authorized changes to executed repository code remain outside that control.

Resilience and Maintainability Implications

  • observed — The new lane has no explicit registry logout or kubeconfig deletion, and resource teardown is best-effort. Another E2E workflow documents disposal of its runner after the job, providing counterevidence to cross-job persistence but not proof for this runner class. The shared sandbox entrypoint periodically exits when no external processes remain; its 30-minute setting is not a hard termination deadline.

Hardening Proposals

  • proposed — Document the lane's per-job runner isolation and disposal contract, including forced termination. As defense in depth, scope registry authentication to temporary job-specific stores and explicitly remove authentication files and the generated kubeconfig during teardown. These are hardening proposals, not established vulnerabilities.

Comment thread hack/isp-hosted-lane_test.bats
isp-hosted shipped unable to converge and nothing noticed, because no
lane installs it: every e2e lane runs isp-full on Talos, where
Cozystack provides the CNI and storage itself. This suite installs it
the way it is meant to run, through the hosted installer variant on a
cluster that brings its own CNI, kube-proxy and default StorageClass,
and passes only when every HelmRelease is Ready and the variant really
left out the data plane it delegates to the host.

The lane installs the latest GHCR nightly on a kind cluster once a day,
after the nightly has published. It takes no pull request trigger: a
run would install the nightly's images, not the pull request's, and
report on code the pull request did not change.

The unit test holds the lane's wiring in place, since a lane that
quietly installed another variant would test something other than
its name says. The sandbox headroom check reads any workflow touching
packages/core/testing as one that boots the QEMU guests; this lane
starts only the sandbox container, so it is exempted by name, after
the job match, and is sized like the others if it ever starts calling
the guest targets.

The check looked for one CRD by name, so a cluster carrying only part
of Cilium's CRDs passed as a cluster without Cilium, and a failed
lookup read as an absent CRD and passed too. It now lists the CRD
groups once, fails if that list cannot be read, and fails on any CRD
in cilium.io.

Verdict: LGTM

Tightly scoped lane and the wiring holds up end to end. Everything it points at resolves:

  • ghcr.io/cozystack/cozystack/cozystack-packages:nightly is actually published by nightly.yaml (the floating tag, DST_REGISTRY=ghcr.io/cozystack/cozystack), so the oras manifest fetch ...:nightly resolve step has something to read, and the 05:00 cron sits three hours behind nightly's 02:00 as the comment claims.
  • The install asserts success rather than exiting 0. hack/cozytest.sh runs each @test under set -eu and does exit "$rc" on the first failure, and the Install Cozystack into sandbox step wraps make ... install-cozystack-hosted in if ! make ...; then ...; exit 1. The suite's own checks (HelmReleases Ready, platform and tenant-root Ready, the variant actually emitted, no cilium.io CRDs and no replicated/local StorageClass) are all written as positive if ...; then exit 1; fi, which sidesteps the swallowed ! cmd problem under the runner.
  • Credentials are handled right: GITHUB_TOKEN goes through --password-stdin from an env var, never on a command line or into the log.
  • cmd/cozystack-operator/main.go:695, packages/core/platform/values-isp-hosted.yaml, and the cozystackOperator.platformSource{Url,Ref} keys the staging step patches all exist, so the isp-hosted-lane_test.bats wiring checks are pinned to real targets.

Two non-blocking CI-hygiene notes:

  1. .github/workflows/e2e-isp-hosted.yaml:22: the schedule has no fork/ref guard. nightly.yaml gates its cron with if: vars.NIGHTLY_ENABLED == 'true' || workflow_dispatch, e2e-proxmox.yaml with vars.PROXMOX_NIGHTLY, and build-arm64-nightly.yaml refuses a non-main ref in its first step. With none of those, a fork that has Actions enabled will attempt this daily, queue on the missing oracle-vm-24cpu-96gb-x86-64 label, and pile up cancelled runs. Harmless to this repo; a vars.-gate or a ref guard would match the siblings.
  2. On failure the lane surfaces only through GitHub's native scheduled-run notification. That is what every other cron e2e lane here does, so it is not a gap this PR introduces; raising it only in case team-wide alerting on the daily lanes is worth a separate look.

## What this PR does

Unit tests on main are red, and that blocks E2E on every open PR. Three
contracts broke the same way. In each case a check from one PR and a
line from another merged a few minutes apart on 2026-10-05, with no
textual conflict. Any one of them alone keeps the job red, so they are
fixed together.

The first is the pin on how a suite reads HelmRelease history. #4689
added it. It accepts `$(kubectl ...` and, since #3594, the bounded
`$(_cozy_guard_kubectl ...` wrapper. Nothing in front of kubectl is
allowed. The monitoring suite from #4678 bounds that read with
`$(timeout 30 kubectl ...`, and the bound is wanted. So the pin now
accepts an optional `timeout [-k N] N` in front of kubectl. The prefix
is spelled out on purpose. Any text would also let through `$(echo
kubectl ...)`, which names the shared expansion without running it, and
that form is now a refuse case. I checked it with mutations: the new
accept cases fail against the old pattern, and a pin that takes any
prefix fails a refuse case.

The second is the flux install in workflows. #4645 forbids running
fluxcd.io/install.sh and moved every workflow to the SHA-pinned
fluxcd/flux2 action. The isp-hosted lane from #4712 still ran the
script. It now uses the same action and version.

The third is the negated-assertion audit. It reads the find operand in
`\( ! -type d` in select-e2e_test.bats as a shell negation and fails.
The line now says `-not -type d`. This is the same change as #4748, so
this PR supersedes it. The audit bug itself is #4752.

After the Go fix, the full log of the unit job had only these two bats
failures left.

Closes #4750
Closes #4755

## Summary by CodeRabbit

* **Bug Fixes**
* History checks now recognize direct `kubectl` reads and reads through
the supported wrapper, including timeout-bounded commands with an
optional kill-grace setting. Commands that only include `kubectl` as an
argument, use similarly named commands, or place a timeout before the
wrapper are not treated as reads.
* **Chores**
* The hosted end-to-end workflow now uses a pinned Flux version, and
suite selection handles directory exclusions consistently.
