Which file should I download?
containerd-<VERSION>-<OS>-<ARCH>.tar.gz: ✅Recommended. Dynamically linked with glibc 2.35 (Ubuntu 22.04).containerd-static-<VERSION>-<OS>-<ARCH>.tar.gz: Statically linked. Expected to be used on Linux distributions that do not use glibc >= 2.35. Not position-independent.
In addition to containerd, typically you will have to install runc
and CNI plugins from their official sites too.
See also the Getting Started documentation.
