Provide option for Custom Configuration for Cilium Overlay Networking #3212

Open jan-walther opened 5 months ago

jan-walther commented 5 months ago

Description of the feature you would like to add / User story

As a customer I would like to be able to configure Cilium in detail in order to utilize e.g. Cilium's L2 Load Balancing. For example configuring the IP range in the KubeOne manifest.

Solution details

Change the KubeOne resource to accept more Cilium parameters
Modify the builtin cni-cilium add-on to accept more values from the KubeOne manifest

Alternative approaches

Allow disabling the default CNI add-on so that users can supply their own CNI add-on

Use cases

Replace MetalLB with Ciliums L2 load balancing

Additional information

hello @jan-walther, I'd suggest to use helm chart from the upstream directly. KubeOne addons will never be as configurable as helm chart.

On one hand, we would also like this, on the other hand we're currently deploying the Cilium Helm chart through Kubeone's helmReleases functionality, which works surprisingly well.

We plan to document this below (with Helm chart deployment) and not to implement it into KubeOne
