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.
