The short version

  • Each has a real cost: kind requires Docker or Podman, so it inherits whatever container runtime limitations exist on the host; Mozilla Firefox no longer supported on Windows 8.1 and earlier versions (users must use Firefox ESR)
  • They diverge on capability: kind covers Nodes as containers, Mozilla Firefox covers Enhanced tracking protection.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

kind

  • Requires Docker or Podman, so it inherits whatever container runtime limitations exist on the host
  • Fewer conveniences than minikube: no addon system, so ingress and metrics need manual installation
  • Because nodes are containers sharing the host kernel, it is a weaker simulation of real node behaviour and storage

Mozilla Firefox

  • No longer supported on Windows 8.1 and earlier versions (users must use Firefox ESR)
  • No longer supported on macOS 10.14 and earlier versions (users must use Firefox ESR)

kind: Why run Kubernetes nodes as containers?

Speed and cost. A container node starts in seconds and uses far less memory than a virtual machine, which is what makes per-CI-run clusters realistic.

kind: Is kind suitable for production?

No. It is a development and testing tool, and node isolation is weaker than real nodes because containers share the host kernel.
