kubespray-defaults currently does two things:
- records a number of default variable values (in particular values used
in several places)
- gather and compose some complex network facts (in particular,
`fallback_ip` and `no_proxy`
There is no actual reason to couple those two things, and it makes using
defaults more difficult (because computing the network facts is somewhat
expensive, we don't want to do it willy-nilly)
Split the two and adjust import paths as needed.
* containerd: add hashes for 1.5.8 and 1.4.12 and make 1.5.8 the new default
* containerd: make nerdctl mandatory for container_manager = containerd
* nerdctl: bump to version 0.14.0
* containerd: use nerdctl for image manipulation
* OpenSuSE: install basic nerdctl dependencies
* Containerd: download containerd from upstream instead of using distro specific packages
split runc download to separate role
make bootstrap-os role deploy container-selinux and seccomp libraries
clean up package manager provided containerd
move variables to docker role that are no longer common with containerd
* Containerd: make molecule testing more relevant
* replace ubuntu18 with ubuntu20
* add centos8 and debian11 to molecule tests
* run kubernetes/preinstall role to ensure relevancy
of test including dependency packages
* CI: adjust test scenarios for downloaded containerd
