Some lines ignored the zap encoder entirely, so `kubectl logs | jq` could
never work:
I0917 19:50:02.580097 1 leaderelection.go:258] "Attempting to acquire
leader lease..." lock="egress-proxies-operator-system/b47711d1..."
That is klog's own stderr writer, not ours. client-go's leader elector
calls klog.FromContext(ctx), and controller-runtime hands the elector a
context with no logr in it -- mgr.Start receives ctrl.SetupSignalHandler(),
which carries no logger. FromContext falls back to Background(), and with
no logger registered that is klog's text sink. Nothing here imported or
configured klog; it was an indirect dependency that around 60 linked
packages use, including client-go/tools/{leaderelection,cache,record} and
client-go/transport. controller-runtime does not route it either -- its
only klog.SetLogger call is in its own test suite.
Plain klog.SetLogger, deliberately not SetLoggerWithOptions with
ContextualLogger(true). The contextual form is what klog's docs recommend
because it skips a klogr round trip, but it also disables klog's verbosity
gate and hands the decision to zap, whose level under Development is Debug
-- so client-go's V(1) chatter, suppressed today by klog's own -v=0, would
have started appearing. Plain SetLogger keeps klog's check in front and
still redirects what it does emit. Same fix to the format, no new volume,
which matters because volume is what prompted this.
The discovery API's http.Server set no ErrorLog, so net/http's own faults
(a failed Accept, a panic escaping a handler) went to the stdlib logger on
stderr. It now drains into logr through logr.ToSlogHandler, the pattern
internal/provider/gcp/wirelog.go already uses for the same purpose.
The deployment gets --zap-encoder=json and --zap-time-encoding=rfc3339.
The flag beats the in-code Development default -- addDefaults fills
NewEncoder only when it is nil -- and the time encoding is not optional,
since the JSON encoder defaults to epoch seconds. Verbosity stays at debug
on purpose; --zap-log-level=info drops the per-RPC lines.
zap.Options{Development: true} stays as the in-code default: flipping it
would change the format for every deployment of this operator, and the
flags get the same result here without that reach.
k8s.io/klog/v2 moves from indirect to direct in go.mod. It was already in
the module graph, so nothing new is downloaded.
No tests: three changes, all wiring, in a file with no test coverage, and
pinning klog.SetLogger means mutating process-global state that leaks into
every other test in the package. Verified in-cluster instead --
`kubectl logs | jq -e -s 'length > 0'` now passes, which fails if any
single line is not JSON.

Per-host connection pool over SSH with the libvirt unix socket forwarded
through the session, lazy dial and redial after disconnect, context
cancellation for go-libvirt's context-less RPCs, handshake deadline and
SSH keepalives. Error classification onto the provider taxonomy. Tested
with a fake dialer and an in-process SSH server that forwards unix sockets.

Introduces internal/provider/kvm with the side-effect-free pieces of the
provider: providerID format/parse, the namespaced <metadata> element that
carries the GC contract, q35 domain XML over pool volumes, volume XML for
overlays and raw seeds, the NoCloud seed ISO built with kdomanski/iso9660,
and config defaults. All unit-tested.

Create/Get/Delete/ListByTag against real corev1.Pod objects in the same
cluster the operator runs in, running an ubuntu/squid container -- picked
by actually checking Docker Hub metadata (Canonical-published, rebuilt
the same day this was decided, 50M+ pulls) rather than guessing an image
reference. It's a public image, so kind nodes pull it directly with no
build/load step.
providerID is "<namespace>/<podName>", parsed via
cache.SplitMetaNamespaceKey -- the same self-contained-providerID
reasoning the plan already calls for on the GCP provider's zone-qualified
IDs. Pod state maps to InstanceState with Succeeded/Failed/Unknown all
collapsing to Terminated, since the reconciler already treats Stopped and
Terminated identically; Running-without-PodIP maps to Provisioning so an
empty IP is never published.
The client is built internally via ctrl.GetConfig() (in-cluster or local
kubeconfig, whichever applies), not threaded through the registry
Constructor signature -- this is what lets `make run` against a local
kind cluster and running in-cluster share the exact same code path with
no provider-specific wiring in cmd/main.go. New() is deliberately
untested (0% coverage): it's the one function that must never run under
`go test`, since it would happily connect to whatever cluster the
developer's kubeconfig points at. Tests construct Provider via an
unexported newWithClient(client, cfg) instead.
ListByTag lists Pods across every namespace (orphan GC needs to find
every tagged Pod regardless of where it landed), which means this
provider's RBAC has to be a ClusterRole rather than namespace-scoped --
flagged now, wired in Step 10.
provider.Config gains KubernetesConfig (replacing MockConfig) and drops
the FailWith*/fault-injection surface entirely, since that need is now
served by a small in-test stub Provider for reconciler tests (Step 4),
not a config-driven mechanism on a real provider package.
Tests use sigs.k8s.io/controller-runtime/pkg/client/fake -- real Pod
objects, the real client.Client interface -- at 77.6% coverage.

The Provider interface (Create/Get/Delete/ListByTag), Instance, and
CreateRequest that every cloud backend implements — kept independent of
api/v1alpha1 so this package has no CRD-type coupling.
Error taxonomy (ErrNotFound/ErrQuotaExceeded/ErrTransient/ErrPermanent)
wrapped via a multi-error Unwrap() []error, so errors.Is and errors.As
both work off the same value: the reconciler branches on classification,
logs keep the underlying SDK error. Unclassified errors default to
ErrTransient — retrying is always safer than latching Failed.
Deterministic instance naming (SHA-256 -> base32 -> 16 chars, 22 total
with the "proxy-" prefix) satisfying GCP's RFC1035 name rules with
headroom, and idempotency-tested across 10k UIDs with zero collisions.
--providers-config YAML parsing (config.go) with fail-fast validation:
unknown type, duplicate name, missing gcp.project, mismatched
type/config-block, and strict-mode rejection of unknown keys.
internal/provider/registry/registry.go takes its type->constructor map
as a parameter rather than hardcoding it, so the package has zero import
on internal/provider/mock or internal/provider/gcp (neither exists yet —
mock is Step 3, gcp is Step 8) and compiles today. Explicit wiring moves
to the composition root in cmd/main.go (Step 10).
Deferred internal/provider/metrics.go (the WithMetrics decorator) to
Step 9, where the Prometheus vectors it needs actually get built —
nothing in this step depends on it.
internal/provider at 96.2% coverage, internal/provider/registry at 100%.

Bootstraps the empty repo into a kubebuilder go/v4 project: group
crawl.example.com, version v1alpha1, kind Proxy (namespaced). Keeps the
existing module path and preserves the repo's Go/testing/changelog
conventions from CLAUDE.md untouched.
Drops the scaffolded GitHub Actions workflows since the remote is Gitea,
not GitHub. Everything else is default kubebuilder output, unmodified,
so later diffs stay reviewable against a known baseline.
