Activates the previously-templated `letsencrypt-dns01-prod` ClusterIssuer
in bp-cert-manager by shipping the missing piece — a Go binary that
satisfies cert-manager's external webhook contract
(`webhook.acme.cert-manager.io/v1alpha1`) against the Dynadot api3.json.
Architecture
============
* `core/pkg/dynadot-client/` — canonical Dynadot HTTP client (shared with
pool-domain-manager and catalyst-dns). Encapsulates the api3.json
transport, command builders, response decoding, and the safe
read-modify-write semantics required to never accidentally wipe a
zone (memory: feedback_dynadot_dns.md). Destructive `set_dns2`
variant is unexported.
* `core/cmd/cert-manager-dynadot-webhook/` — the cert-manager webhook
binary. Implements `Solver.Present` via the client's append-only
`AddRecord` path and `Solver.CleanUp` via the read-modify-write
`RemoveSubRecord` path. Domain allowlist (`DYNADOT_MANAGED_DOMAINS`)
rejects challenges for unmanaged apexes BEFORE any Dynadot call.
* `platform/cert-manager-dynadot-webhook/` — Catalyst-authored Helm
wrapper. Templates Deployment + Service + APIService + serving
Certificate (CA chain via cert-manager Issuer self-signing) +
RBAC + ServiceAccount. Mirrors the standard cert-manager external-
webhook deployment shape.
* `platform/cert-manager/chart/` — flips `dns01.enabled: true` so the
paired ClusterIssuer activates. The interim http01 issuer remains
templated as the rollback path.
Test results
============
core/pkg/dynadot-client — 7 tests PASS (race-clean)
core/cmd/cert-manager-dynadot-... — 9 tests PASS (race-clean)
Test coverage includes a Present/CleanUp round-trip against an
httptest fixture that models Dynadot's zone state, an explicit
unmanaged-domain rejection, a regression preserving a pre-existing
CNAME across the DNS-01 round-trip (the zone-wipe defence), and a
typed-error propagation test that surfaces `ErrInvalidToken` to
cert-manager so the controller will retry.
Helm template smoke render
==========================
`helm template` against the new chart with default values yields 12
resources / 424 lines (APIService, Certificate, ClusterRoleBinding,
Deployment, Issuer, Role, RoleBinding, Service, ServiceAccount). The
modified bp-cert-manager chart still renders both ClusterIssuers
(`letsencrypt-dns01-prod` + `letsencrypt-http01-prod`) with default
values; flipping `certManager.issuers.dns01.enabled=false` is the
clean rollback.
Smoke command (post-deploy)
===========================
kubectl get apiservices.apiregistration.k8s.io \
v1alpha1.acme.dynadot.openova.io
# Issue a *.<sovereign>.<pool> wildcard cert and watch the
# Order/Challenge progress through cert-manager.
CI
==
`.github/workflows/build-cert-manager-dynadot-webhook.yaml` mirrors the
pool-domain-manager-build pattern (cosign keyless signing, SBOM
attestation, GHCR push at `ghcr.io/openova-io/openova/cert-manager-
dynadot-webhook:<sha>`). Triggered by changes to either the binary or
the shared dynadot-client package.
Closes #159
