Running Containerd and k3s on MacOS
summary
Lima and Rancher Desktop make containerd and k3s run on macOS by running a QEMU VM with filesystem sharing, automatic port mapping and host-aware DNS/proxy propagation; Lima replaces slow reverse‑SSH mounts with virtio‑fs replacing reverse SSH and exposes a host resolver that honors VPN, mDNS and /etc/hosts. Rancher Desktop adds a GUI, k3s integration, Trivy image scanning and choice of containerd or moby. Project momentum is real: ~8,000 stars, 400+ PRs, 45 contributors, but expect up to three‑second port‑forward delays and no UDP tunneling yet.
