by setting a default runtime spec with a patch for RLIMIT_NOFILE.
- Introduces containerd_base_runtime_spec_rlimit_nofile.
- Generates base_runtime_spec on-the-fly, to use the containerd version
of the node.
For the following configuration
```
containerd_insecure_registries:
docker.io:
- dockerhubcache.example.com
```
the rendered /etc/containerd/config.toml contains
```
[plugins."io.containerd.grpc.v1.cri".registry.configs."docker.io".tls]
insecure_skip_verify = true
```
but it needs to be
```
[plugins."io.containerd.grpc.v1.cri".registry.configs."dockerhubcache.example.com".tls]
insecure_skip_verify = true
```
When running molecule jobs, we saw the folloing warning message:
[DEPRECATION WARNING]: [defaults]callback_whitelist option, normalizing names
to new standard, use callbacks_enabled instead. This feature will be removed
from ansible-core in version 2.15. Deprecation warnings can be disabled by
setting deprecation_warnings=False in ansible.cfg.
callbacks_enabled has been added since Ansible 2.11 and Kubespray is using
Ansible 2.12 at master branch. So we can use callbacks_enabled safely to
avoid the warning message.
* Force containerd service unmasking
Force systemd to unmask and start service when adding containerd service
* Eliminate restart and move unmasking step
Switch to start instead of restart
Move unmasking to restart handler
* Add unmasking to similar container runtimes
* Add missing service names
* Update config.toml.j2
i think this commit code is not completed works
exam registry address : a.com:5000
insecure registry must be http://a.com:5000
but this code add insecure a.com:5000 (without http://)
If there is no http, containerd accesses with https even if insecure_skip_verify = true
solution is code edit
* Update config.toml.j2
* Update containerd.yml
* Update containerd.yml
* Update containerd.yml
* Update config.toml.j2
* containerd: change default resolvconf_mode to host_resolvconf
* Wait for kube-apiserver to come back after pod refresh
* Handle resolv.conf gracefully
* Retain currently configured DNS entries to ensure we don't break the resolvers
* Suse uses wickedd for network management so no dhcp hooks
* Molecule: increase ansible timeout
* CI: Increase ansible timeout to 120s for Packet jobs
* 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
* Add Rocky as a known OS
* Make sure Rocky includes bootstrap-centos.yml
* Update docs with Rocky Linux
* Rocky Linux wireguard and EPEL
* Rocky Linux in the list of supported distributions
* set selinux type t_etc if selinux state is enforcing
* workaround with update repo is no longer needed
remove comments about failing playbook
* grubby is not available in distros using ostree
* remove docker support because removed in fcos
update install script example with live rootfs
* do not call grubby on ostree based distro
* update docs enabling containerd on fedora coreos
* Ansible: move to Ansible 3.4.0 which uses ansible-base 2.10.10
* Docs: add a note about ansible upgrade post 2.9.x
* CI: ensure ansible is removed before ansible 3.x is installed to avoid pip failures
* Ansible: use newer ansible-lint
* Fix ansible-lint 5.0.11 found issues
* syntax issues
* risky-file-permissions
* var-naming
* role-name
* molecule tests
* Mitogen: use 0.3.0rc1 which adds support for ansible 2.10+
* Pin ansible-base to 2.10.11 to get package fix on RHEL8
* Override the default value of containerd's root, state, and oom_score configurations
* Add tests data for containerd_storage_dir, containerd_state_dir and containerd_oom_score variables
* AlmaLinux: ansible>2.9.19 is needed to know about AlmaLinux
* AlmaLinux: identify as a centos derrivative
* AlmaLinux: add AlmaLinux to checks for CentOS
* Use ansible_os_family to compare family and not distribution
* Add containerd_extra_args
This is useful for custom containerd config, e.g. auth

* Make containerd config.toml mode 0640
It may contain sensitive information like password

This replaces kube-master with kube_control_plane because of [1]:
The Kubernetes project is moving away from wording that is
considered offensive. A new working group WG Naming was created
to track this work, and the word "master" was declared as offensive.
A proposal was formalized for replacing the word "master" with
"control plane". This means it should be removed from source code,
documentation, and user-facing configuration from Kubernetes and
its sub-projects.
NOTE: The reason why this changes it to kube_control_plane not
kube-control-plane is for valid group names on ansible.

When privileged is enabled for a container, all the `/dev/*` block
devices from the host are mounted into the guest. The
`privileged_without_host_devices` flag prevents host devices from
being passed to privileged containers.

By default Ansible stat module compute checksum, list extended attributes and find mime type
To find all stat invocations that really use one of those:
git grep -F stat. | grep -vE 'stat.(islnk|exists|lnk_source|writeable)'

This was introduced in 143e2272ff
Extra repo is enabled by default in CentOS, and is not the right repo for EL8
Instead of adding a CentOS repo to RHEL, enable the needed RHEL repos with rhsm_repository
For RHEL 7, we need the "extras" repo for container-selinux
For RHEL 8, we need the "appstream" repo for container-selinux, ipvsadm and socat

yum_repository expect really different params, so nothing to factor here
Ubuntu is not an ansible_os_family, the OS family for Ubuntu is Debian
Check for ansible_pkg_mgr == apt
