Huge kubelet image size #78

Open sergelogvinov opened 5 months ago

Hello,

We didn't notice how the size increased.

I believe that kubelet had csi in-tree a few years before. Now most of them have out-of-tree implementation. (or removed)

Probably we need to rethink included packages in this container. Or at least have a second tiny version of it.

What do you think @frezbo ?

frezbo commented 5 months ago

I think it was same size for a long time

I think cutting down dependencies is an interesting idea, but still even with CSI out-of-tree, kubelet supports mounting e.g. cephfs as volume mount directly iirc.

Hm, i think only fc, iscsi are in-tree now.

I think ceph too, kubelet supports mounting remote ceph fs (which i think is one of the major contributor to size)
