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.
* feat(external-provisioner/local-path-provisioner): adds support for local path provisioner
Helpful for local development but also in production workloads (once the
permission model is worked out) where you have redundancy built into the
software uses the PVCs (e.g. database cluster with synchronous
replication)
* feat(local-path-provisioner): adds debug flag, image tag group var
* fix(local-path-provisioner): moves image repo/tag to download role
* test(gce_centos7-flannel): enables local-path-provisioner in test case
* fix(addons): add image repo/tag to commented default values
* fix(local-path-provisioner): typo in jinja template for local path provisioner
* style(local-path-provisioner): debug flag condition re-formatted
* fix(local-path-provisioner): adds missing default value for debug flag
* fix(local-path-provisioner): syntax fix for debug if condition end
* fix(local-path-provisioner): jinja template syntax: if condition white space
* OCI subnet AD 2 is not required for CCM >= 0.7.0
Reorganize OCI provider to generate configuration, rather than pull
Add pull secret option to OCI cloud provider
* Updated oci example to document new parameters
* Set cluster DNS correctly in case of nodelocal dns cache
* Pass in cluster_ip based on dns mode
* Disable nodelocaldns by default
* Fix syntax error
* Fix syntax issue
* Add nodelocadns ip to vars of node installation
* Change location of nodelocaldns_ip
* Try to remove newlines from jinja template
* Add debug for config file
* Move parameter logic outside of template
* Adapt templates after feedback
* Remove debugging
Looks like the template is removing the trailing space between storage
class entries, and since CI only has one storage class we never hit this
issue. This change will prevent the yaml from printing on a single line
when multiple storage classes are defined.
- Fixed an issue where storage class host directories were looped
through excessive target hosts
- Fixes examples in the LVP `README.md` to use nested dicts instead of a
list of dicts
* Makes local volume provisioner more dynamic
* Correct variable name in local storage provisioner defaults
* Updates external-provisioner readme
* Updates variable naming to be more clear, more documentation, fixes sample inventory
* Variable refactor, untangled some jinja2 loops
* Corrects variable name
* No variable substitution in dict keys, replaced with anchor
* Fixes default storage_classes dict, inline docs
* Fixes spelling in inline docs
* Addresses comments in review
* Updates all the defaults
* Fix failing CI task
* Fixes external provisioner daemonset
* 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.

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
* 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
* 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
* Added Priority class to tiller installation and also fixed tiller override implementation.
* Added changes to handle priority classes separately in tiller, instead of using the variable tiller_override
* Fix DNS loop when resolvconf_mode is set to host_resolvconf
* 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
- Local Volume StorageClass configuration is now manged by `local_volume_provisioner_storage_classes`, a list of maps that specifies local storage classes with `name` `host_dir` and `mount_dir` keys per entry
- Tasks and templates updated to loop through local volume storage classes
- Previous defaults for path/class names were not changed
- Fixed an issue where a `kubernetes/preinstall` was creating directories inconsistently with the `kubernetes-apps/external_provisioner/local_volume_provisioner` task
According to the documentation, container images are described
by vars like `foo_image_repo` and `foo_image_tag`.
The variables netcheck_{agent,server}_{img_repo,tag} do not
follow that convention.
* Changes to assign pod priority to kube components.
* Removed the boolean flag pod_priority_assignment
* Created new priorityclass k8s-cluster-critical
* Created new priorityclass k8s-cluster-critical
* Fixed the trailing spaces
* Fixed the trailing spaces
* Added kube version check while creating Priority Class k8s-cluster-critical
* Moved k8s-cluster-critical.yml
* Moved k8s-cluster-critical.yml to kube_config_dir
When enable_network_policy is set to True with Calico 3 kubectl
apply fails with the error:
The Deployment "calico-kube-controllers" is invalid:
spec.strategy.rollingUpdate: Forbidden: may not be specified when

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
