Introduced variable `ingress_nginx_tolerations` to set custom
tolerations for Ingress nginx daemonset, to be able to schedule
ingress-nginx on dedicated nodes with taints.
* Update defaults to match k8s 1.12 suggestions
* Test if Netchecker works with node ip instead of localhost
* Update defaults to ipvs and coredns
* Update defaults for kube_apiserver_insecure_port
* Update main.yaml
When `ansible_user` is not root, using `-b` option.
And with `download_run_once` and `download_localhost` set `true`.
Ansible will executes `container_download | upload container images to nodes` task.
It uses rsync to upload images to `/tmp/release/container/`, but the
`container` directory owned by `root`.
Now the `kubespray-aws-inventory.py` script always set a node_labels key
to ansible_host.
When AWS instance did not set property labels, it would be an empty
string.
The TASK `Write kubelet config file (kubeadm or non-kubeadm)` will
failed with a msg:
`AnsibleUndefinedVariable: 'unicode object' has no attribute 'items'`.
* Support Metrics Server as addon (#3560).
* Update metrics server v0.3.1.
* Add metrics server test.
* Replace metrics server manifests with kubernetes/cluster/addons's.
* Modify metrics server manifests for kubespray.
* Follow PR#3558 node label node-role.kubernetes.io/master change
* Fix metrics server parameters base_metrics_server_... to metrics_server_...
* Fix too hard corded metrics_server_memory_per_node
* Add configurable insecure tls for metrics-apiservice
* Downloadable addon-resizer and extract parameter as variables
* Remove metrics server version from deployment name
* Metrics Server work when all masters has node role
* Download metrics-server and add-resizer container only on master
* ServiceAccount and ConfigMap is separated and fix application name
* Remove old metrics server clusterrole template
* Fix addon-resizer image specify
* Make InternalIP default for metrics_server_kubelet_preferred_address_types
Make InternalIP default because multiple preferrred address types does not work.
comparison that happens during `TASK [kubernetes-apps/ansible : Kubernetes Apps | Lay Down CoreDNS Template]` where the `dns-autoscaler` template is deployed causes coredns to fail deployment. The error is caused by the variable `dns_prevent_single_point_failure` where an integer is being compared with a string. The resulting error:
```bash
'>' not supported between instances of 'int' and 'str'
```
prevents successful deployment of CoreDNS.
The change makes the comparison happen between integers and allows CoreDNS to succeed.
* Enable AutoScaler for CoreDNS
* Only use one template for dns autoscaler
* Rename a few variables for replicas and minimum pods
* Rename a few variables for replicas and minimum pods
* Remove replicas to make autoscale work
* Cleanup kubedns-autoscaler as it has been renamed
add prometheus annotations to calico-node if
calico_felix_prometheusmetricsenabled is enabled.
This will allow a kubernetes_sd to automaticly find the pods and start
scraping.
