* Refactor calico-rr to run in k8s cluster with taint
Change-Id: I75a3169ff5b36ce8302fc7ef1c32d3eb697b5afa
* add preinstall checks
* rework calico/rr role
Change-Id: I2f0a7e6cb77cf91ad4a615923680760d2e5d9ca8
* add empty calico-rr group
Change-Id: I006c0a60db9b72d02245bf8fdfabcf982144a5ad
* 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 d6fd0d2aca 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.
* 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.
* 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.
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
* 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.)
* 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.

Introduced variable node_taints which can be set in inventory for
specific hosts or in group_vars, which generates --register-with-taints
command line argument for kubelet.
* Adds support for Multus (multiple interfaces) CNI plugin
Multus is a latin word for "Multi". As the name suggests, it acts as a
Multi plugin in Kubernetes and provides multiple network interface
support in a pod. Multus uses the concept of invoking delegates by
grouping multiple plugins into delegates and invoking them in the
sequential order of the CNI configuration file provided in json format.
* Change CNI version (0.1.0->0.3.1) of Contiv to be compatible with Multus
* [jjo] add kube-router support
Fixescloudnativelabs/kube-router#147.
* add kube-router as another network_plugin choice
* support most used kube-router flags via
`kube_router_foo` vars as other plugins
* implement replacing kube-proxy (--run-service-proxy=true) via
`kube_proxy_mode: none`, verified in a _non kubeadm_enabled_
install, should also work for recent kubeadm releases via
`skipKubeProxyInstall: true` config
* [jjo] address PR#3339 review from @woopstar
* add busybox image used by kube-router to downloads
* fix busybox download groups key
* rework kubeadm_enabled + kube_router_run_service_proxy
- verify it working ok w/the kubeadm_enabled and
kube_router_run_service_proxy true or false
- introduce `kube_proxy_remove` fact, to decouple logic
from kube_proxy_mode (which affects kubeadm configmap
settings, thus no-good to ab-use it to 'none')
* improve kube-router.md re: kubeadm_enabled and kube_router_run_service_proxy
* address @woopstar latest review
* add inventory/sample/group_vars/k8s-cluster/k8s-net-kube-router.yml

* Make sure upstream_dns_servers is defined when using resolvconf_mode == 'host_resolvconf'
* Only set upstream dns servers on KubeDNS and CoreDNS if they are defined
* Only set upstream dns servers on KubeDNS and CoreDNS if they are defined
* fix openstack cli syntax

Set dns list correct. Thanks to @whereismyjetpack
Only download KubeDNS or CoreDNS if selected
Move dns cleanup to its own file and import tasks based on dns mode
