Networking Core Module Release 4.0.0

Welcome to the latest release of the Networking module of SIGHUP Distribution maintained by team SIGHUP by ReeVo.

This new major release updates Cilium to 1.18.11, Calico to 3.31.6, and introduces support for Kubernets 1.35.

Packages version 🚢

Component Current Version Previous Version
cilium v1.18.11 v1.18.7
tigera-operator v1.40.13 v1.40.3

Bug fixes 🐞

  • [#105] Add whisker observability: enable Calico's Whisker observability UI and its required Goldmane flow aggregator as defaults in the tigera/on-prem package.
  • [#107] Fix Calico Grafana dashboard: "CPU Usage" and "Memory Usage" metrics are now populated.

Breaking Changes 💔

  • [#109] Remove Cilium Core Package: Cilium previously was provided in two variants: Core and Core+Hubble. The Core variant has been deprecated in favour of keeping a single package Core+Hubble.
  • [#112] Rename ConfigMap: ConfigMaps holding Grafana Dashboards for Cilium and Hubble (kube-system/cilium-grafana-dashboard and kube-system/hubble-grafana-dashboard) have been renamed to follow the upstream names.

Update Guide 🦮

Tigera Calico On Premises

kustomize build katalog/tigera/on-prem | kubectl apply -f -

Cilium

Note

If you were using the core only variant of Cilium you will now get the one with Hubble instead.

If you were pointing to the core package (katalog/cilium/core) or the hubble package (katalog/cilium/hubble) directly, update the reference to katalog/cilium.

See the Breaking changes section for more details.

ConfigMaps holding Grafana Dashboards for Cilium have changed name to use the same as upstream. If you are using kubectl apply you need to manually delete the old configmaps before applying the new ones:

kubectl delete configmap -n kube-system cilium-grafana-dashboard hubble-grafana-dashboard

Apply the Kustomize project with the new version:

kustomize build katalog/cilium | kubectl apply -f -

Important

The new single package introduces a cyclic dependency between Cilium and cert-manager. Hubble (deployed together with Cilium) requires cert-manager, and cert-manager requires at least some nodes to be ready (CNI working) to be scheduled.

You may need to adjust your deployment strategy while switching to the unified package.

For example, if you are using a tool that verifies dependencies (like Carvel kapp) you may apply cert-manager and cilium together in the same kapp deploy command.

If you are using plain kubectl apply instead, you will see some messages saying that the resources that require cert-manager (like Certificate, Issuer, etc.) are not being deployed. You will need to re-apply the cilium package after you've deployed cert-manager so Hubble works.
