[virtualization][kubernetes_adminsitration] Add CAs to Kind cluster #563

Open LukeShortCloud opened 3 years ago

Manually:

$ sudo docker cp <PATH_TO>/ca.crt <CONTAINER_ID>:/usr/local/share/ca-certificates/
$ sudo docker exec -it <CONTAINER_ID> update-ca-certificates && systemctl restart containerd.service

Automatically:

I am unsure if the automatic / Cluster API method is exposed / usable for Kind. Especially unsure if it would work for the Docker back-end.
