Why can kubeadm fail to run on a lightweight distribution such as Alpine Linux?

  1. Alpine cannot run a CRI runtime
  2. Its kernel is too new for the preflight check
  3. kubeadm binaries are dynamically linked against glibc, which it lacks
  4. kubeadm requires systemd as the init system
Show the answer

Answer: C. kubeadm binaries are dynamically linked against glibc, which it lacks

kubeadm assumes glibc; a distribution without it needs a compatibility layer providing the expected symbols.
