This was introduced in ef7f5edb
obsoletes=0 is not present in the official repo config
https://download.docker.com/linux/centos/docker-ce.repo


so it might not be needed for some time

no_proxy is a pain to get right, and having proxy variables present causes issues
(k8s components get proxy configuration after upgrade, see #7100)

It's better to only configure what require proxy:
- the runtime (containerd/docker/crio)
- the package manager + apt_key
- the download tasks

Tested with the following clusters
- 4 CentOS 8 nodes
- 1 Ubuntu 20.04 node

All packages have proper dependencies in latest versions

Upgrading docker / containerd without adapting the configuration might break the node,
so disable docker-ce repo by default.
We are already using dpkg hold for Debian.

All containerd.io packages provide /usr/bin/runc, so no need to check

yum_conf was never used for containerd

module_hotfixes should not be needed with the EL8 repo

This will make sure an upgrade doesn't upgrade the docker cli.

* Ensure libseccomp is installed before starting containerd on CentOS 8

* Simplify libseccomp install on CentOS 8

- Uses `package` module
- Replaces complex version check with 'state: latest'. The version must
  be > 2.3 when using with cri-o.
- Removes unnecessary `not is_ostree` condition as CentOS 8 does not use
  ostree

* Moved docker_dns_options to defaults so it can be overridden

* Fixed yaml indentation and markdown

* Moved docker_dns_search_domains to defaults

* Manage containerd.io package with docker CRI.

* Refactor common containerd stuff to separate role

* Fix check mode and unnecessary shell.

* Fix proxy and module_hotfixes

On CentOS 8 with proxy ansible render inline `proxy` and `module_hotfixes` options.

For example:

`proxy=http://127.0.0.1:3128module_hotfixes=True`

But expected result:

```
proxy=http://127.0.0.1:3128
module_hotfixes=True
```

* Use ini_file module for work with ini files

* Prevent duplicates proxy= option in /etc/yum.conf

Module `lineinfile` is weak, use most powerful module `ini_file` and add or remove `proxy=` when `http_proxy` is defined or not.

we can't set module_hotfixes=True using yum_repository ansible module

value was previously defined in other variables. This change removes
the dockerproject_.+_repo_.+ docker variables in favor of the older
ones.

* Remove stale legacy yum docker repo /etc/yum.repos.d/docker.repo

* move task 'Remove legacy docker repo file' to pre-upgrade.yml

* Change dockerproject.org to download.docker.com

dockerproject.org was deprecated in 2017 and has gone down.

Fixed Issue #1032

test case for OEL7 AIL with kubeadm

Add packet CI stuff for oracle 7

* Add support for Docker plugins

* support multiple Docker plugins using looped include

* fix yamllint error

* use dpkg_selections module to hold docker-ce on Debian family hosts

* removed debian_docker.j2 template as it is no longer required

* Vagrantfile: Bump openSUSE to Leap 15.0

* roles: container-engine: Add 'containerd' package for openSUSE

The 'containerd' package contains the docker-containerd and
docker-containerd-shim binaries. We also need to ensure that the latest
version is installed since an older version may already be present (eg GCE
images)

* Remove docker log-opts for opensuse

* roles: bootstrap-os: Use lowercase 'o' for openSUSE

OpenSUSE is not a valid family name. The correct one is openSUSE

* roles: bootstrap-os: Update zypper cache before first installation

The zypper cache may be outdated so ensure that it's fully updated
before we try and install the bootstrap packages.

Both the `yum` and `apt` modules support a list as input, this allows us avoid the slower `with_items` approach, which can take a long time with a large count of cluster nodes.

Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.
