unkinben 1d87c42fc1 Add advise-mode VPA for every workload (#283)
## Why

Turns on right-sizing telemetry for the whole estate. Adds a `VerticalPodAutoscaler` with `updateMode: "Off"` (recommendation-only, advise mode) for every Deployment and StatefulSet in `apps/base`. Off mode never evicts or mutates pods, so this is purely observational: the VPA recommender (added in the vpa-system PR) publishes suggested requests/limits in each VPA's status, and nothing acts on them until someone deliberately flips a mode.

## Changes

- Add one `vpa.yaml` per app under `apps/base/<app>/` containing a `<workload>-vpa` VerticalPodAutoscaler for each workload, and register it in that app's `kustomization.yaml`.
- Coverage: 17 workloads across 11 apps.
  - age-api (age-api), artifactapi (api, redis, ui), authentik (redis), bind-system (bind-operator), cephrgw-system (cephrgw-operator), encapi (encapi), kanidm (kanidm StatefulSet), litellm (litellm, redis), paperclip (paperclip), pdbmux (pdbmux), puppet (puppetboard, puppetdb, puppetserver-compiler, puppetserver-master).

## Skipped (intentionally)

- **CNPG `Cluster` objects** (artifactapi, authentik, encapi, grafana, litellm, paperclip, puppet, woodpecker) — Postgres is managed by CloudNativePG, not a VPA target.
- **CronJobs** (puppet g10k/generate-types, reposync x4) — not VPA-able.

## HPA / VPA caveat

api, ui (artifactapi), litellm, and all four puppet deployments also carry an HPA. With `updateMode: "Off"` there is no conflict today (VPA only recommends). VPA objects targeting these carry an inline comment: do **not** flip to `Auto`/`Initial` while the HPA still autoscales on CPU/memory, or the two controllers will fight over the same resource. Move the HPA to a custom/non-resource metric first.

## Verification

- `kubectl kustomize` over every touched overlay: 9/11 overlays PASS rendering all their VPAs; 2 failures are pre-existing and unrelated to this change — `authentik` fails on a local helm-tooling flag error identically on origin/main, and `paperclip` has no `apps/overlays/au-syd1/paperclip` directory yet. Both apps' base kustomizations build clean and render their VPA.

## Merge gate

- **Requires the vpa-system CRDs PR (argocd-apps #281) to merge first.** These manifests use `autoscaling.k8s.io/v1 VerticalPodAutoscaler`; without the CRDs installed, ArgoCD sync fails on an unknown kind.

unkinben 05318553d6 Swap puppet compiler ENC to the encapic Go binary (#277)
## Why

The puppet-on-k8s compilers classify nodes with a uv/python ENC script (`encapi-enc`). Each fresh compiler pod resolves the script's python dependencies on first invocation, and that resolution fails on cold pods (observed exits 135/2), breaking puppet agent catalog compilation. `encapic` (git.unkin.net/unkin/encapic) is a stdlib-only Go replacement with no runtime dependency resolution — a behavioural drop-in whose output matches the python script byte-for-byte.

## Changes

- Points the compiler `external_nodes` at `/opt/bin/encapic`.
- Reworks the `setup-shared-bins` init container to `curl` the encapic `v0.1.0` `encapic_linux_amd64` release binary (sha256-verified against the published `.sha256`, installed mode 0755) into the shared bins dir, instead of copying the python script and installing uv.
- Removes the `puppet-encapi-enc` configmap generator, its volume and mount, and the `resources/encapi-enc` script. uv was consumed solely by that script (grep of `apps/base/puppet` confirms no other consumer), so its installation is removed too.

`kubectl kustomize apps/overlays/au-syd1/puppet` builds clean.

## Merge gate

Do not merge until the encapic `v0.1.0` release assets exist:
`https://git.unkin.net/unkin/encapic/releases/download/v0.1.0/encapic_linux_amd64` (+ `.sha256`). The init container pulls them at pod start.

## Rollback

Revert this PR to restore the `encapi-enc` configmap script + uv install and repoint `external_nodes`.

unkinben 3af12180fd Switch puppet compiler ENC from Cobbler to encapi (#272)
## Why

The k8s puppetserver compilers classify nodes via an exec ENC that today queries legacy Cobbler (`https://cobbler.main.unkin.net`) over TLS. `encapi` now runs in-cluster and exposes a cobbler-wire-compatible endpoint (`GET /cblr/svc/op/puppet/hostname/<certname>`), a drop-in for the Cobbler URL. This cuts the puppet-on-k8s ENC over from Cobbler to encapi — a prerequisite for migrating VM agents onto puppet-on-k8s.

## Changes

- Rename the ENC script `resources/cobbler-enc` -> `resources/encapi-enc`, and its configmap `puppet-cobbler-enc` -> `puppet-encapi-enc` (kustomization configMapGenerator + deployment volume, initContainer copy path, and volumeMount subPath).
- Point `external_nodes` in the compiler `puppet.conf` at `/opt/bin/encapi-enc`.
- Target the in-cluster encapi service `http://encapi.encapi.svc.cluster.local` (plain HTTP), overridable via the `ENCAPI_URL` env var.
- Drop the `/opt/vault-ca-cert.crt` verify for the ENC request (no TLS needed in-cluster).
- Leave the response normalization identical: classes coerced to a list, `enc_role`/`enc_env` params set, `environment` stripped when it equals `testing`.

Verified with `kubectl kustomize apps/overlays/au-syd1/puppet` (builds clean, exit 0); the generated `puppet-encapi-enc` configmap contains the new URL and env var.

## 🚨 Merge gate

**Do not merge until encapi is seeded** (terraform-incus `benvin/encapi-seed` PR applied). An empty encapi means every node resolves to a 404. On 404 the ENC script exits non-zero, so puppet fails the compile rather than classifying the node with zero classes — nodes will fail to run until they exist in encapi. Seed encapi first so real nodes classify correctly; only unknown nodes should 404.

- TLS terminated at the Gateway listener; cert-manager provisions the certificate via `vault-issuer`
- external-dns annotations moved to the Gateway
- `ingress_puppetboard.yaml` is unchanged in this PR (separate PR)

## Test plan

- [ ] ArgoCD syncs the puppet app cleanly
- [ ] cert-manager issues the `puppetdb-tls` certificate

unkinben 0fc1268c51 fix: install filemapper gem and deploy generate-types cronjob (#71)
The network module's interfaces provider requires puppetx/filemapper
which was not installed, causing catalog compilation failures with
"no such file to load -- puppetx/filemapper".

Adds filemapper to additional-ruby-gems.sh for puppetserver/compiler
pods, installs it directly in the generate-types cronjob (which has no
access to that script), and adds cronjob_generate-types.yaml to the
kustomization so the CronJob is actually deployed.

unkinben 2a96d9e948 feat: add PuppetDB read-only database user and pooler (#69)
PuppetDB requires a separate read-only database user for its read pool.
Without it, it refuses to use the write user for read queries and all
/pdb/query/v4 calls fail with a 500.

- Add puppetdb_read role via CNPG managed.roles with password sourced
  from a new postgres-read-credentials Vault secret
- Grant CONNECT, USAGE, SELECT and default privileges to puppetdb_read
  via postInitApplicationSQL (must also be run manually on existing cluster)
- Add puppet-postgres-pooler-ro Pooler (type: ro) routing to replicas
- Add puppetdb-read-database-conf ConfigMap with read-database.conf
  mounted into /etc/puppetlabs/puppetdb/conf.d/ in the PuppetDB deployment
- Wire OPENVOXDB_READ_POSTGRES_* env vars from the new secret

features from the openvox helm chart and improving on them. changes from
helm are:
- using vault for storing secrets
- using g10k instead of r10k
- using a single shared g10k cronjob for all masters/compilers
- using a single shared /etc/puppetlabs/code directory (shared, cephfs)

changes:
- deploy puppet master and compiler servers with statefulset/deployment
- deploy puppetdb with postgresql backend, taking advantage of cnpg cluster and pooler
- deploy puppetboard
- all supporting configmaps, services, ingresses, and hpas
- added vaultstaticsecret for eyaml private keys
- configured secure mounting of eyaml keys at /var/lib/puppet/keys/
- updated base kustomization to include all 23 new puppet resource files

working towards a larger, redundant, autoscaling and simple puppet
implementation in kubernetes. this was originally based on the openvox
helm chart with several improvements (not all in this pr)

- use of cnpg instead of single bitnamilegacy postgres container
- use for g10k instead of r10k
- run one instance of g10k per namespace, instead of per-pod
- store only keep one copy of the environments/branches (instead of per-pod)
- change g10k to native cronjob instead of hacky implementation
- use vault secrets

part one adds:

- cnpg puppetdb pgsql cluster
- cnpg puppetdb pgpooler
- persistent volume claims for puppet, puppetdb, the code repository, etc
