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.
* Fix Failure talking to yum: Cannot find a valid baseurl for repo: base/7/x86_64 if Install packages in CentOS using proxy
* Add proxy to /etc/yum.conf if http_proxy is defined

* Added new files for cleaning up orphans and docker & kubelet directories
* Added new lines at the end of these files
* removed the trailing whitespaces from main.yml and clean-up.yml
* Updated as per the review comments
* Updated as per the review comments
* Removed service_facts and package_facts because they are not supported in ansible 2.4.0
* Corrected yaml syntax errors
* Removed the use of json_query filter and utilized selectattr
* Removed trailing spaces
* Changed the default value of docker_clean_up to false
* Added Changes to only include cleanup-docker-orphans.sh
* Reverted back changes done inside handler.
* Removed trailing spaces and made default value of docker_orphan_clean_up as true
* Reverted the default value of docker_orphan_clean_up as false
* Made the docker clean up as drop in
* Made the docker clean up as drop in
* Reverted the value of boolean docker_orphan_clean_up to false
* Converted ExecStop to ExecSTartPost. Removed the live restore check from the orphan script
* 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
When using resolvconf_mode host_resolvconf, there is an early DNS
config stage where Kubernetes cluster DNS is not injected for host
DNS intially. Later, the cluster DNS is enabled, but we do not
need to run every task from the kubernetes/preinstall role.
kube-router v0.2.1 highlights from changelog:
- IPv6 WIP but pretty close to full working functionality
- fully support network policy semantics with addition of support for
ipblock and except
* warning on meta flush_handlers
* avoid rm
* avoid "Module remote_tmp /root/.ansible/tmp did not exist and was created with a mode of 0700, this may cause issues when running as another user. To avoid this, create the remote_tmp dir with the correct permissions manually" warning on subsequent tasks using blockinfile
* is match
* failed
* version_compare
* succeeded
* skipped
* success
* version_compare becomes version since ansible 2.5
* ansible minimal version updated in doc and spec
* last version_compare
* [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
The hosts(5) manpage clearly states that the first entry is the
"canonical name", or FQDN (Fully-Qualified Domain Name):
IP_address canonical_hostname [aliases...]
By using the alias as a first entry, `hostname -f` does not return the
correct domain which breaks all sorts of unrelated functionality (it
has impact over email server configuration, for example).
