[2.13] Backport CI fix (#7119 )

* [2.14] fix ci (#7021) * fix flake8 errors in Kubespray CI - tox-inventory-builder * fix flake8 errors in Kubespray CI - tox-inventory-builder * Invalidate CRI-O kubic repo's cache Signed-off-by: Victor Morales <v.morales@samsung.com> * add support to configure pkg install retries and use in CI job tf-ovh_ubuntu18-calico (due to it failing often) * Switch Calico and Cilium image repos to Quay.io Co-authored-by: Victor Morales <v.morales@samsung.com> Co-authored-by: Barry Melbourne <9964974+bmelbourne@users.noreply.github.com> Conflicts: roles/download/defaults/main.yml * up vagrant box to fedora/33-cloud-base in cri-o molecule tests (cherry picked from commit 06ec5393d7) * add Google proxy-mirror-cache for docker hub to CI tests (cherry picked from commit d739a6bb2f) * containerd docker hub registry mirror support * containerd docker hub registry mirror support * add docs * fix typo * fix yamllint * fix indent in sample and ansible-playbook param in testcases_run * fix md * mv common vars to tests/common/_docker_hub_registry_mirror.yml * checkout vars to upgrade tests (cherry picked from commit 4a8a52bad9) * Exclude .git/ from shellcheck If a branch name contains '.sh', current shellcheck checks the branch file under .git/ and outputs error because the format is not shell script one. This makes shellcheck exclude files under .git/ to avoid this issue. (cherry picked from commit e2467d87b6) Co-authored-by: Hans Feldt <2808287+hafe@users.noreply.github.com> Co-authored-by: Sergey <s.bondarev@southbridge.ru> Co-authored-by: Kenichi Omichi <ken-oomichi@wx.jp.nec.com> * Switch some image from dockerhub to k8s.gcr (also increase pkg retries) (#6955) * Set packet_centos8-kube-ovn test to manual Signed-off-by: Rick Haan <rickhaan94@gmail.com> Co-authored-by: Etienne Champetier <champetier.etienne@gmail.com> Co-authored-by: Hans Feldt <2808287+hafe@users.noreply.github.com> Co-authored-by: Sergey <s.bondarev@southbridge.ru> Co-authored-by: Kenichi Omichi <ken-oomichi@wx.jp.nec.com> Co-authored-by: Florian Ruynat <16313165+floryut@users.noreply.github.com>

 It is recommended to use filter to manage the GitHub email notification, see [examples for setting filters to Kubernetes Github notifications](https://github.com/kubernetes/community/blob/master/communication/best-practices.md#examples-for-setting-filters-to-kubernetes-github-notifications)

-To install development dependencies you can set up a python virtual env with the necessary dependencies:
-
-```ShellSession
-virtualenv venv
-source venv/bin/activate
-pip install -r tests/requirements.txt
-```
+To install development dependencies you can use `pip install -r tests/requirements.txt`

+probably pointing on a task depending on a module present in requirements.txt (i.e. "unseal vault").

 One way of solving this would be to uninstall the Ansible package and then, to install it via pip but it is not always possible.
 A workaround consists of setting `ANSIBLE_LIBRARY` and `ANSIBLE_MODULE_UTILS` environment variables respectively to the `ansible/modules` and `ansible/module_utils` subdirectories of pip packages installation location, which can be found in the Location field of the output of `pip show [package]` before executing `ansible-playbook`.

-A simple way to ensure you get all the correct version of Ansible is to use the [pre-built docker image from Quay](https://quay.io/repository/kubespray/kubespray?tab=tags).
-You will then need to use [bind mounts](https://docs.docker.com/storage/bind-mounts/) to get the inventory and ssh key into the container, like this:
-
-```ShellSession
-git checkout v2.20.0
-docker pull quay.io/kubespray/kubespray:v2.20.0

- The list of available docker version is 18.09, 19.03 and 20.10. The recommended docker version is 20.10. The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).
- The cri-o version should be aligned with the respective kubernetes version (i.e. kube_version=1.20.x, crio_version=1.20)
+Note: The list of validated [docker versions](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.16.md) was updated to 1.13.1, 17.03, 17.06, 17.09, 18.06, 18.09. kubeadm now properly recognizes Docker 18.09.0 and newer, but still treats 18.06 as the default supported version. The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).

+# Deploy MetalLB into Kubespray/Kubernetes
+```
+MetalLB hooks into your Kubernetes cluster, and provides a network load-balancer implementation. In short, it allows you to create Kubernetes services of type “LoadBalancer” in clusters that don’t run on a cloud provider, and thus cannot simply hook into paid products to provide load-balancers.
+```
+This playbook aims to automate [this](https://metallb.universe.tf/concepts/layer2/). It deploys MetalLB into kubernetes and sets up a layer 2 loadbalancer.
+
+## Install
+```
+Defaults can be found in contrib/metallb/roles/provision/defaults/main.yml. You can override the defaults by copying the contents of this file to somewhere in inventory/mycluster/group_vars such as inventory/mycluster/groups_vars/k8s-cluster/addons.yml and making any adjustments as required.

 Change that file to reflect your local setup (adding more machines or removing them and setting the adequate ip numbers), and save it to `inventory/sample/k8s_gfs_inventory`. Make sure that the settings on `inventory/sample/group_vars/all.yml` make sense with your deployment. Then execute change to the kubespray root folder, and execute (supposing that the machines are all using ubuntu):

-```shell
+```
 ansible-playbook -b --become-user=root -i inventory/sample/k8s_gfs_inventory --user=ubuntu ./cluster.yml

 This will provision your Kubernetes cluster. Then, to provision and configure the GlusterFS cluster, from the same directory execute:

 If your machines are not using Ubuntu, you need to change the `--user=ubuntu` to the correct user. Alternatively, if your Kubernetes machines are using one OS and your GlusterFS a different one, you can instead specify the `ansible_ssh_user=<correct-user>` variable in the inventory file that you just created, for each machine/VM:

You can open these using whatever firewall you wish (this can easily be configured using the `geerlingguy.firewall` role).

 Available variables are listed below, along with default values (see `defaults/main.yml`):

-```yaml
-glusterfs_default_release: ""
-```
+    glusterfs_default_release: ""

 You can specify a `default_release` for apt on Debian/Ubuntu by overriding this variable. This is helpful if you need a different package or version for the main GlusterFS packages (e.g. GlusterFS 3.5.x instead of 3.2.x with the `wheezy-backports` default release on Debian Wheezy).

-```yaml
-glusterfs_ppa_use: yes
-glusterfs_ppa_version: "3.5"
-```
+    glusterfs_ppa_use: yes
+    glusterfs_ppa_version: "3.5"

 For Ubuntu, specify whether to use the official Gluster PPA, and which version of the PPA to use. See Gluster's [Getting Started Guide](https://docs.gluster.org/en/latest/Quick-Start-Guide/Quickstart/) for more info.

 # Deploy Heketi/Glusterfs into Kubespray/Kubernetes
-
 This playbook aims to automate [this](https://github.com/heketi/heketi/blob/master/docs/admin/install-kubernetes.md) tutorial. It deploys heketi/glusterfs into kubernetes and sets up a storageclass.

-## Important notice
-
-> Due to resource limits on the current project maintainers and general lack of contributions we are considering placing Heketi into a [near-maintenance mode](https://github.com/heketi/heketi#important-notice)
-
 ## Client Setup
-
 Heketi provides a CLI that provides users with a means to administer the deployment and configuration of GlusterFS in Kubernetes. [Download and install the heketi-cli](https://github.com/heketi/heketi/releases) on your client machine.

 ## Install
-
 Copy the inventory.yml.sample over to inventory/sample/k8s_heketi_inventory.yml and change it according to your setup.
-
-```shell
+```
 ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi.yml
 ```

 ## Tear down
-
-```shell
+```
 ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi-tear-down.yml
 ```

-# Offline deployment
-
-## manage-offline-container-images.sh
-
-Container image collecting script for offline deployment
-
-This script has two features:
-(1) Get container images from an environment which is deployed online.
-(2) Deploy local container registry and register the container images to the registry.
-
-Step(1) should be done online site as a preparation, then we bring the gotten images
-to the target offline environment. if images are from a private registry,
-you need to set `PRIVATE_REGISTRY` environment variable.
-Then we will run step(2) for registering the images to local registry.
-
-Step(1) can be operated with:
-
-```shell
-manage-offline-container-images.sh   create
-```
-
-Step(2) can be operated with:
-
-```shell
-manage-offline-container-images.sh   register
-```
-
-## generate_list.sh
-
-This script generates the list of downloaded files and the list of container images by `roles/download/defaults/main.yml` file.
-
-Run this script will execute `generate_list.yml` playbook in kubespray root directory and generate four files,
-all downloaded files url in files.list, all container images in images.list, jinja2 templates in *.template.
-
-```shell
-./generate_list.sh
-tree temp
-temp
-├── files.list
-├── files.list.template
-├── images.list
-└── images.list.template
-0 directories, 5 files
-```
-
-In some cases you may want to update some component version, you can declare version variables in ansible inventory file or group_vars,
-then run `./generate_list.sh -i [inventory_file]` to update file.list and images.list.
-
-## manage-offline-files.sh
-
-This script will download all files according to `temp/files.list` and run nginx container to provide offline file download.
-
-Step(1) generate `files.list`
-
-```shell
-./generate_list.sh
-```
-
-Step(2) download files and run nginx container
-
-```shell
-./manage-offline-files.sh
-```
-
-when nginx container is running, it can be accessed through <http://127.0.0.1:8080/>.

This makes shellcheck exclude files under .git/ to avoid this issue.
