The 98e7a07fba commit udpates the
dashboard version to 2.0.0 but it enable skip login flag wasn't
updated. This change updates its identation to avoid issues when
dashboard_skip_login is enabled.
* bump to dashboard 2.0 rc6 with metrics scrapper
* fix missing yaml seperator making Replicaset complaining about missing ServiceAccount
* unwanted legay gross hack forgot to remove before
* no need namespace on CrBinding
* bump to 2.0.0 release
* remove dashboard_metrics_scrapper_enabled
* replace removed repo with kubic repository for centos 7
* add crio configuration for centos8
* add crio configurations for debian

* simplify calulation of required crio version
- gives possibility to overwrite
* change default path for runc

* declare kubic repo for ubuntu
* do not install crictl twice
* 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
The playbook that bootstrap openSUSE servers assumes that the
/etc/sysconfig/proxy file exists but the execution fails when
these file is not present. This change guarantees its existence.
* assembly fallback_ips and no_proxy var only one time on localhost and populate result on all hosts
* add tag always, fix ansible lint errors

- fix cni path for fcos
* added required permissions for querying endpointslice resources
* copy-pasted role permissions from cilium install manifests
* bumped cilium version to v1.7.2
* 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.

The variable is defined in `kubernetes/preinstall` role and used in several roles. Since `kubernetes/preinstall` is not always included when `ansible-playbook` is run with tag selectors (see #5734 for reason), they will fail, or individual roles must copy the same fact definitions (as in #3846). Moving the definition to the always-included `kubespray-defaults` role will resolve the dependency problem.
- This solves issue #5721 & #5713 (dupes)
- Provide a cleaner default usage pattern for the download role

Defaults to the upstream default https://docs.projectcalico.org/v3.9/reference/felix/configuration

This allows coexistence with other firewall management technologies.
* Add a note to the sample config
* 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
The 'regexp' parameter matches last occurrence of a line starting with 'proxy=' and replaces it with the one defined in 'line' parameter. If no match - it works same way as before. This fixes resuming cluster deployments failed after that task (if there was no more than one line starting with 'proxy' in the yum.conf file - this condition should also be reassured with the change introduced here) eg. if they were initiated with Terraform.

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.

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.

Kubespray Pull Request #5084 (https://github.com/kubernetes-sigs/kubespray/pull/5084) caused more problems than it solved due to limitations with the synchronize module. See comments on Kubespray Issues #5059 (https://github.com/kubernetes-sigs/kubespray/issues/5059) and #5116 (https://github.com/kubernetes-sigs/kubespray/issues/5116). Details from Ansible documentation: "Currently, synchronize is limited to elevating permissions via passwordless sudo. This is because rsync itself is connecting to the remote machine and rsync doesn’t give us a way to pass sudo credentials in. ... Currently there are only a few connection types which support synchronize (ssh, paramiko, local, and docker) because a sync strategy has been determined for those connection types. Note that the connection for these must not need a password as rsync itself is making the connection and rsync does not provide us a way to pass a password to the connection. ..." Thus, reverting Pull Request #5084.

When using cluster.yml or scale.yml to add/scale nodes in the existing
k8s cluster, the `kubeadm init` wouldn't run. As a result, kube-proxy
wouldn't be created, and therefore the kube-proxy deletion task would
fail, e.g. in the case where kube-router is used and "kube_proxy_remove"
is set to true. As a workaround, add ignore_errors to the kube-proxy
deletion task.
The script is not usable unless you are in the '.vagrant/provisioners/ansible/inventory/artifacts' folder.

- do not run etcd role when etcd_kubeadm_enabled == true

mirror repos in countries like China, where the default accesses are

mydict.keys() should be converted to list,

Fix for Kubespray Issue #5059 (https://github.com/kubernetes-sigs/kubespray/issues/5059). There is a known issue with the 'fetch' module that will sometimes lead to it failing with a memory error. See ansible/ansible#11702 (https://github.com/ansible/ansible/issues/11702). I encountered this issue with the "Copy kubectl binary to ansible host" task in kubespray/roles/kubernetes/client/tasks/main.yml, and it caused my entire deployment to error out (see "Output of ansible run" above). Replacing 'fetch' with 'synchronize' fixes this issue.

* File and container image downloads are now cached localy, so that repeated vagrant up/down runs do not trigger downloading of those files. This is especially useful on laptops with kubernetes runnig locally on vm's. The total size of the cache, after an ansible run, is currently around 800MB, so bandwidth (=time) savings can be quite significant.
* When download_run_once is false, the default is still not to cache, but setting download_force_cache will still enable caching.
* The local cache location can be set with download_cache_dir and defaults to /tmp/kubernetes_cache
* A local docker instance is no longer required to cache docker images; Images are cached to file. A local docker instance is still required, though, if you wish to download images on localhost.

Not all code was included verbatim, but each feature of that commit was checked to be working in this patch. One notable change: The actual downloading of the kubeadm images was moved to {download,sync)_container, to enable caching.
Note 1: I considered splitting this patch, but most changes that are not directly related to caching, are a pleasant by-product of implementing the caching code, so splitting would be impractical.
Note 2: I have my doubts about the usefulness of the upload, download and upgrade tags in the download role. Must they remain or can they be removed? If anybody knows, then please speak up.

Kubespray waits exit of every drain before run other one.
Running drain every after each other seems better than parallel, because we should check resources availability every time.
But, this way, we have one additional problem: possible restart pods on the nodes that are killed little bit later.
Fast cordon before heavy drain seems like an easy solution.

- SETUID

Without this, pulls are considered for all
hosts groups, even if not targetted by the downloads
`groups` list. Hence, a download/sync is triggered
even though the host does not require the image.
* Disable kube_api_anonymous_auth by default to secure the setup
* Disable metrics-server in addons. Health endpoint is slow and unstable
* Fix anonymous-auth missing in configuration
* Cleanup a bit
* Fix kube anon auth
* Download to delegate and sync files when download_run_once
* Fail on error after saving container image
* Do not set changed status when downloaded container was up to date
* Only sync containers when they are actually required
Previously, non-required images (pull_required=false as
image existed on target host) were synced to the target
hosts. This failed as the image was not downloaded to
the download_delegate and hence was not available for
syncing.
* Sync containers when only missing on some hosts
* Consider images with multiple repo tags
* Enable kubeadm images pull/syncing with download_delegate
* Use kubeadm images list to pull/sync
'kubeadm config images pull' is replaced by collecting the images
list with 'kubeadm config images list' and using the commonly
used method of pull/syncing the images.
* Ensure containers are downloaded and synced for all hosts
* Fix download/syncing when download_delegate is a kubernetes host
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.
