After host reboot kubelet and crio goes into a loop and no container is started.
storage_driver in crio.conf overrides system defaults in etc/containers/storage.conf
/etc/containers/storage.conf is installed by package containers-common dependency
installed from cri-o (centos7) and contains "overlay".
Hosts already configured with overlay2 should be reconfigured and the
/var/lib/containers content removed.
By default do not allow "unqualified" (without a registry) images
because it is considered unsecure and subject to mitm attacks.
To enable insecure pull configure for example:
crio_registries:
- "docker.io"
- "quay.io"
* log level by default increased to 'info'
* cgroup manager by default set to 'systemd'
* stream port (used by kubelet) bound to 127.0.0.1 for security reasons
* metrics can be enabled and port specified
CI job 624031102 failed with:
fatal: [ubuntu1804]: FAILED! => {"changed": false, "msg": "Failed to download key at https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/xUbuntu_18.04/Release.key: Request failed: <urlopen error [Errno -3] Temporary failure in name resolution>"}
Assuming its a temporary problem it should get more robust with a
couple of retries like in other roles.

* move fedora repo modular tasks to crio_repo file
* move centos repo tasks to crio_repo
* declare crio version matrix for ubuntu
* update documentation crio support for ubuntu
* Add proxy support to CRI-O service
The crio.service requires proxy environment variables when it's
deployed behind a corporated network. This change creates a systemd
configuration file when the proxy variables are defined.
* Remove unnecesary crio's tasks
* fix upgrade of crio on fcos
- update documents
* install conntrack required by kube-proxy
- like commit 48c41bcbe7

- path of seccomp_profile depends on distribution
* allow to override crio configuration
- fix path for ubuntu
* allow to override crio configuration
- fix cni path for fcos
* 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.

* fedora coreos support
- handle all ostree like os in same way for crio
* fedora coreos support
- add fcos documentations
* Add docker-ce 19.03 packages for Debian & Ubuntu
K8s has updated the recommended Docker version to 19.03. More
specifically it should be 19.03.4, but since we used 18.06.7 instead of
.2, I'm assuming the latest patch version should be used here as well.
* Add docker 19.03 for redhat
This 38688a4486 change replaces the
value for dockerproject_.+_repo_.+ docker variables but their new
value was previously defined in other variables. This change removes
the dockerproject_.+_repo_.+ docker variables in favor of the older
ones.
* containerd: add proxy support

* kubespray-defaults: add kube_service_addresses / kube_pods_subnet to no_proxy
CIDR notation in no_proxy is supported by a lot of programs/languages,
including go: https://github.com/golang/go/issues/16704
Without that containerd cannot talk the the API server (kube_apiserver_ip),
but it should not go through an external proxy for the nodes/pods/services

* Fix crictl
* Reload systemd daemon before enabling service
* Typo
* Add crictl template
* Remove seccomp.json for ubuntu
* Set runtime path of runc for ubuntu
* Change path to conmon
There is no cri-tools package in CentOS/EPEL/Red Hat.
Additionally, cri-tools is provided into the installation via
roles/download/defaults/main.yml:104:crictl_download_url.
* Fix python3-libselinux installation for RHEL/CentOS 8
In bootstrap-centos.yml we haven't gathered the facts,
so #5127 couldn't work
Minimum ansible version to run kubespray is 2.7.8,
so ansible_distribution_major_version is defined an there is no need to default it

When docker_container_storage_setup is false,
docker service should not depend on docker-storage-setup service,
because it's not installed.
For example, when using overlay2 on recent RHEL 7/Centos 7 kernels,
you most likely don't need it.
We don't need to support upgrades from 2 year old installs,
just from the last major version.
Also changed most retried tasks to 1s delay instead of longer.
