Allow configuration of alternative kubelet directories #5913
Description
Is this a BUG REPORT or FEATURE REQUEST?: Feature Request
/kind enhancement
What happened:
I attempted to install KubeVirt and I couldn't because the distribution of Kubernetes I am using (k0s) uses a non-standard kubelet directory (/var/lib/k0s/kubelet versus /var/lib/kubelet).
What you expected to happen:
KubeVirt to offer a way to change the expected kubelet directory
How to reproduce it (as minimally and precisely as possible):
Attempt to install KubeVirt on a distribution of kubernetes like k3s or k0s
Anything else we need to know?:
This is related to #5069. This seems to also be a problem with k3s (and a previous version of microk8s which has since changed back, I assume), and probably any distribution that uses a non-standard kubelet path.
I worked around this by symlinking /var/lib/kubelet to /var/lib/k0s/kubelet. Not a great solution (discussed @ k0sproject/k0s#428)
Environment:
- KubeVirt version (use
virtctl version):
Client Version: version.Info{GitVersion:"v0.41.0", GitCommit:"b7f322409e310ebaf7edb9f657d9864ad5730ab0", GitTreeState:"clean", BuildDate:"2021-05-12T14:43:31Z", GoVersion:"go1.13.14", Compiler:"gc", Platform:"linux/amd64"}

NOTE: technically I couldn't get this version before KubeVirt succesfully installed.
