Marian Koreniuk 7500a9fbae test(kubernetes): add the Proxmox e2e suite, parked disabled
Upstream CI has no hypervisor, so this suite cannot run there; it ships
`.disabled` and is run by a lane that owns a Proxmox stand.

Named for what the chart actually creates. The resource definition prefixes the
release, so a Kubernetes CR called k8s-e2e produces
ProxmoxCluster/kubernetes-k8s-e2e in the tenant's own namespace, and the admin
kubeconfig Secret is kubernetes-k8s-e2e-admin-kubeconfig.

Stand-specific values are variables rather than hardcoded. Every one of them is
a bare ${COZY_PVE_*} that run-proxmox.sh expands with envsubst, supplying the
defaults itself — GNU envsubst leaves a ${VAR:-default} in the text exactly as
it is, set or not, and that reaches the apiserver as a string where the schema
wants an integer — and refusing a fixture with a variable still in it. The
StorageClass and the PVC probe read the same COZY_PROXMOX_STORAGE, so the volume
lands where the probe looks. The runner reads the tenant kubeconfig's .conf key,
the address a runner outside the management cluster can reach.
The stand's resource pool comes in through COZY_PVE_POOL, empty by default.
hack/proxmox-e2e-fixture_test.bats pins the shape of the fixture and the render.

The PVC probe reads the storage again after the claim is deleted: a deleted
claim whose disk is still there is the leak the pre-delete hook's Step 1b
exists to prevent. keep_tenant is honoured by the suite's own teardown, not
only by the workflow's. The workflow carries no fallback for the stand's
variables: an unset one fails the job before a key is sent anywhere. The
schedule runs only where vars.PROXMOX_NIGHTLY is true: the job targets a
self-hosted runner with the `proxmox` label, and a scheduled run on a repository
without one would sit in the queue until GitHub cancels it.

The suite also asserts the half of the deployment that lives in the management
cluster — the CSI controller and the cloud-controller-manager — because that is
the property the pair is designed around and a tenant-only assertion would pass
with the token in the wrong place.

Chainsaw E2E tests

The Cozystack E2E app suite, written for Kyverno Chainsaw — a declarative, Kubernetes-native E2E test framework (CNCF, part of the Kyverno project; successor to KUTTL).

This directory replaces the per-app BATS suite that used to live in hack/e2e-apps/*.bats. The CI e2e job runs chainsaw test hack/e2e-chainsaw/ after make install-cozystack; cluster bootstrap (hack/e2e-prepare-cluster.bats, hack/e2e-install-cozystack.bats) and the OpenAPI checks (hack/e2e-test-openapi.bats) remain BATS.

Suites: postgres, bucket, mariadb, mongodb, redis, valkey, qdrant, clickhouse, kafka, rabbitmq, etcd, openbao, harbor, foundationdb, external-dns, kuberture, vminstance, gateway, opensearch, kubernetes-latest, kubernetes-previous, securitygroup.

What Chainsaw buys over the BATS suite

  • Readable tests — a list of resources and expected states, not shell control flow. The timeout N sh -ec "until kubectl get ..." + kubectl wait pair that appeared ~100 times collapses into a single assert that polls existence and state together.
  • Distinguishable failure modes — "object never created", "created but never ready", and "wrong status" all surface as a structured diff instead of an opaque shell timeout.
  • Automatic diagnostics — catch blocks dump events, describe, and pod logs on any failure (the BATS suite only did this in harbor.bats, by hand).
  • Automatic cleanup — resources Chainsaw applied are deleted (and waited on) in reverse order; finally covers operator-created leftovers.
  • CI-ready output — a JUnit chainsaw-report.xml is emitted for the test summary.

Test anatomy

Each suite is a directory with a chainsaw-test.yaml (one or more Test docs) plus the manifests it applies. A step has try (operations: apply, assert, error, script, delete, …), optional catch (diagnostics on failure), and optional finally (teardown regardless of outcome).

Declarative suites assert on status.conditions and concrete fields. Inherently imperative suites keep their logic in script steps:

  • openbao — bao operator init/unseal via kubectl exec.
  • kuberture — jq on Service annotations + external-dns split-horizon log assertions.
  • gateway — admission-rejection cases that need kubectl --as impersonation or error-message greps; the tenant apex is read from the namespace namespace.cozystack.io/host label at runtime so they pass on any host.
  • kubernetes-latest/previous — wrap _lib/run-kubernetes.sh (Kamaji bringup, port-forward, LB/NFS/ouroboros). The script cds to the repo root (the test dir is hack/e2e-chainsaw/<suite>, so repo root is ../../..).

Conventions / gotchas (Chainsaw v0.2.15)

  • Condition asserts use the filter-as-list form, not the documented [0] index:
    status:
      (conditions[?type == 'Ready']):
      - status: "True"
    
    The (conditions[?type == 'Ready'])[0]: {status: "True"} idiom fails with "field not found in the input object".
  • A reading of a failure diff: the "actual" side is a projection onto the expected fields — status: {} means the JMESPath expression failed, not that status is empty. Read the error line above the diff first.
  • error with a bare resource ref (name only) asserts the resource does not exist (used for "PVC reclaimed", "no backup schedule", "child has no Gateway HR").
  • script runs in the test directory with $NAMESPACE set to the config namespace (tenant-test).

Running locally

Requires a cluster with Cozystack installed and a tenant-test namespace (the environment hack/e2e-install-cozystack.bats produces). bucket additionally needs mc, nc, and jq on the host; kuberture/openbao/harbor need jq.

# install chainsaw
go install github.com/kyverno/chainsaw@latest   # or: brew install kyverno/chainsaw/chainsaw

# run all suites (config picked up from .chainsaw.yaml)
cd hack/e2e-chainsaw
chainsaw test

# run a single suite
chainsaw test postgres/

kubernetes-latest/kubernetes-previous each bring up a full tenant Kubernetes cluster (~25 min, real worker nodes) and vminstance boots a nested VM — expect a long run for the full set.

CI integration

The e2e job in .github/workflows/pull-requests.yaml runs make -C packages/core/testing test-chainsaw (which execs chainsaw test hack/e2e-chainsaw/ inside the e2e sandbox) and uploads chainsaw-report.xml. The sandbox image (packages/core/testing/images/e2e-sandbox/Dockerfile) ships the chainsaw binary alongside kubectl/helm/mc/jq/nc.
