* [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
* fix kube_router_run_service_proxy conditional for kube-proxy removal
* fix kube_proxy_remove fact (w/ |bool), add some needed kube-proxy tags on my and existing changes
* update kube-router tolerations for 1.12 compatibility
* add PriorityClass to kube-router DaemonSet
Internet access is not mandatory as long as the user configures all container image repositories to point to internal container registries, in case of on-premises installation with firewall rules preventing direct Internet access.
* calico upgrade to v3
* update calico_rr version
* add missing file
* change contents of main.yml as it was left old version
* enable network policy by default
* remove unneeded task
* Fix kubelet calico settings
* fix when statement
* switch back to node-kubeconfig.yaml
Upgrade Kubernetes to V1.11.2
The kubeadm configuration file version has been upgraded from v1alpha1 to v1alpha2
Add bootstrap kubeadm-config.yaml with external etcd
ingress-nginx 0.16.2 (https://github.com/kubernetes/ingress-nginx/releases/tag/nginx-0.16.2)
This patch simplify ingress-nginx deployment by default deploy on
master, with customizable options; on the other hand, remove the
additional Ansible group "kube-ingress" and its k8s node label
injection.
Reference to https://kubernetes.io/docs/concepts/services-networking/ingress/#prerequisites:
GCE/Google Kubernetes Engine deploys an ingress controller on the master.
By changing `ingress_nginx_nodeselector` plus custom k8s node
label, user could customize the DaemonSet deployment target.
If `ingress_nginx_nodeselector` is empty, will deploy DaemonSet on
every k8s node.
- cephfs-provisioner 06fddbe2 (https://github.com/kubernetes-incubator/external-storage/tree/06fddbe2/ceph/cephfs)
Noteable changes from upstream:
- Added storage class parameters to specify a root path within the backing cephfs and, optionally, use deterministic directory and user names (https://github.com/kubernetes-incubator/external-storage/pull/696)
- Support capacity (https://github.com/kubernetes-incubator/external-storage/pull/770)
- Enable metrics server (https://github.com/kubernetes-incubator/external-storage/pull/797)
Other noteable changes:
- Clean up legacy manifests file naming
- Remove legacy manifests, namespace and storageclass before upgrade
- `cephfs_provisioner_monitors` simplified as string
- Default to new deterministic naming
- Add `reclaimPolicy` support in StorageClass
With legacy non-deterministic naming style (where $UUID are generated ramdonly):
- cephfs_provisioner_claim_root: /volumes/kubernetes
- cephfs_provisioner_deterministic_names: false
- Generated CephFS volume: /volumes/kubernetes/kubernetes-dynamic-pvc-$UUID
- Generated CephFS user: kubernetes-dynamic-user-$UUID
With new default deterministic naming style (where $NAMESPACE and $PVC are predictable):
- cephfs_provisioner_claim_root: /volumes
- cephfs_provisioner_deterministic_names: true
- Generated CephFS volume: /volumes/$NAMESPACE/$PVC
- Generated CephFS user: k8s.$NAMESPACE.$PVC
The README says to check if Python and pip are installed type:
```
python -v && pip -v
```
Lowercase `-v` is `--verbose`, uppercase `-V` is `--version`. The
command should be:
```
python -V && pip -V
```
