* Add support for Docker plugins

* support multiple Docker plugins using looped include

* fix yamllint error

* add macvlan cni to kubespray

* macvlan: lint yaml files and fix sample config file

* macvlan: add OWNERS file

* add macvlan to README

* macvlan : CI first shoot

* macvlan : CI add full masquerade

* delegate retrive pod cidr to master only

* macvlan: add config for CI

* macvlan: add netchecker deployment

* 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.

* Fixed a FIXME, wher the argument was that delegate_to doesn't play nice with omit. That is a correct observation and the fix is to use default(inventory_host) instead of default(omit). See ansible/ansible#26009

* Removed "Register docker images info" task from download_container and set_docker_image_facts because it was faulty and unused.

* Removed redundant when:download.{container,enabled,run_once} conditions from {sync,download}_container.yml

* All features of commit d6fd0d2a by Timoses <timosesu@gmail.com>, merged May 1st 2019, are included in this patch. 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.

* Minor cleanups

* Add comment in docs that nodelocaldns cache is enabled by default

* 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

add the support of the folling property in azure-credential-check.yml
  - azure_loadbalancer_sku: Sku of Load Balancer and Public IP. Candidate values are: basic and standard.
  - azure_exclude_master_from_standard_lb: excludes master nodes from standard load balancer.
  - azure_disable_outbound_snat: disables the outbound SNAT for public load balancer rules
  - useInstanceMetadata: Use instance metadata service where possible
  - azure_primary_availability_set: (Optional) The name of the availability set that should be used as the load balancer backend

Ansible 2.0 has deprecated the “ssh” from ansible_ssh_host.

Updating the docs to be more aligned with the Ansible version used in the sample/inventory.ini file as well.
Also adding `[bastion]` group in the docs to avoid confusion.

Broken since 4efb0b78

* Added generic CNI network plugin

* Added CNI network plugin documentation

* added necessary fix

* 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.

* enable kubelet client certificate rotation

* change to variable kubelet_rotate_certificates

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.

* Lint everything in the repository with yamllint

* yamllint fixes: syntax fixes only

* yamllint fixes: move comments to play names

* yamllint fixes: indent comments in .gitlab-ci.yml file

The correct name is Packet, not Packet Host.

* Create packet.md

* Update README.md

* Update README.md

* Update packet.md

download the latest version

* Update packet.md

* Add docsify website

* Add website CI

* Calico: Ability to define the default IPPool CIDR (instead of kube_pods_subnet)

* Documentation for calico_pool_cidr (and calico_advertise_cluster_ips which has been forgotten...)

--limit doesn't work when using remove-node.yml as there is group listing with "hosts: kube-master" in the playbook. Thus, remove-node/pre-remove/post-remove tasks are skipped as they are filtered by group "hosts: kube-master"

Added a line documenting where to find acceptable values for the
`docker_version` setting. If you use a value that is not used as
a key value by `docker_versioned_pkg` the container-engine/docker
playbook will throw a "Unexpected templating type error". (e.g.
If you use '18.06.1' or '18.06.1-ce', neither of which is used
as a key value of `docker_versioned_pkg`, rather than '18.06',
you'll get an error when installing on Ubuntu 18.04.)

since bad886ca, dns_mode is set to coredns by default instead of kubedns

* Add support for running a nodelocal dns cache

After encountering dns issues in a cluster I was recently working on I
noticed Kubernetes 1.13 introduced support for running a nodelocal dns
cache.

I believe this can usefull for more people.
