Drops the label tracking pin kept through the 3.x upgrades, so Argo CD uses its default argocd.argoproj.io/tracking-id annotation. Labels can be copied by other tools (cert-manager's ingress-shim copied app.kubernetes.io/instance onto Certificates); the annotation names the exact resource. Every app gets synced once right after, so resources removed later are still recognised for pruning.
Nothing deploys disable/: the apps in it (ente-photos, minio, mist, owntracks, traccar, ttrss, whisper and others) are gone from the cluster apart from some old TLS secrets. git history keeps them. The argocd-cm patch copy was an old leftover that kustomize never used.
ingress-nginx is gone and every app is served by the Envoy Gateway. The certificates were created by cert-manager's ingress-shim and are owned by the Ingresses, so each app now declares its Certificate itself, with the same name, secret and usages, so nothing gets reissued. gateway-shim can't take over because the certificates live in the app namespaces.
immich drops mbg.hensen.io, which has no route, so that one certificate is reissued through the Gateway's HTTP-01 solver.
Also removes the Longhorn test-port redirect URI and updates comments that still described nginx.
With server.insecure, TLS ends at nginx or Envoy and argocd-server serves plain HTTP, which is how Argo CD documents the Gateway API setup. The nginx Ingress now talks HTTP to the http port; the ssl-passthrough annotation did nothing without the controller flag. argocd-folder diffs server-side for the new HTTPRoute.
Argo CD 3.0 switches the default to annotation tracking. Per the 2.14->3.0
upgrade notes, a resource whose first sync after the switch is a deletion
gets orphaned instead of pruned. Pinning label tracking (the 2.14 default,
so no change today) keeps the upgrade to 3.x free of that; moving to
annotations can follow once everything runs 3.4.
The Argo CD v2.14.2 image (Ubuntu 24.04, ca-certificates 20240203) and the
dex image still trust the eMudhra intermediates whose keys leaked
(https://emudhra.we-have-a-problem.com), and the repo server fetches git
and Helm repos over that trust store. A forged certificate there means
arbitrary manifests in the cluster.
patched-ca-bundle holds the bundle from Alpine ca-certificates-bundle
20261020-r0 and replaces /etc/ssl/certs in every Argo CD container except
redis. The whole directory goes, since OpenSSL and Go also read the
per-root files next to ca-certificates.crt. It uses server-side apply to
keep the bundle out of the last-applied annotation.
