* remove unused files
* fix strict yaml linter warning and errors
* refactor logical conditions to pull and cache container images
* remove comment due lint check
* document role
* remove image_load_on_localhost, because cached images are always loaded to docker on remote sites
* remove XXX from debug output
* Run 'container-engine' after drain.
Move possibly disruptive role 'container-engine' to run after the node
is drained.
As that role have to be run on non-cluster nodes as well (etcd and
calico-rr), and those nodes are not drained, add play for that case.
* Check if api is up before upgrade.
If container engine is restarted in previous role, api controller can
take some time to start. This check ensures api is up before upgrade.
When kube-router is used as cni, rules might be added to the mangle table
to support external IPs. Therefore, mangle table should be flushed during
reset as well.
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.
* Fix incorrect assertion comparison for kube_network_node_prefix
* Ignore assertion comparison for kube_network_node_prefix when using calico

* updated contiv-etcd and cinder-csi-controllerplugin to use k8s_image_pull_policy variable
* Introduce kubelet_config_extra_args and kubelet_node_config_extra_args to pass params to kubelet via YAML config
* kubelet_config_extra_args is not the alternative

* Set default values for testcase
* Add actual test jobs
* Attempt to satisty gitlab ci linter
* Fix ansible targets
* Set etcd_member_name as stated in the docs...
* Recovering from 0 masters is not supported yet
* Add other master to broken_kube-master group as well
* Increase number of retries to see if etcd needs more time to heal
* Make number of retries for ETCD loops configurable, increase it for recovery CI and document it
* 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

When running with serial != 100%, like upgrade_cluster.yml, we need to apply this fixup each time

Raises limit from 100 to 300 because the default is far too low
and the pod can handle 300 with the given resources.

* 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

Initially this was to fix a mis-indented approvers key. However, it turns
out that 'oilbeater' is not a member of kubernetes-sigs nor
kubernetes-incubator (the org this repo was migrated from). Thus this
OWNERS file is failing prow's validation check.
As a workaround I've opted to move them to emeritus_approver, which
isn't valiated and can be used as a hint for other approvers in this
repo
This fixes the scenario where masters are upgraded one at a time
and coredns gets improperly scaled back up to 2 replicas.
