AWS CSI driver
 2021-01-12 13:36:35 -08:00
Bharath Vedartham a8d709acf2 Default cgroup driver to systemd from k8s 1.20 
Currently, kOps uses cgroupfs cgroup driver for the kubelet and CRIs. This PR defaults
the cgroup driver to systemd for clusters created with k8s versions >= 1.20.

Using systemd as the cgroup-driver is the recommended way as per

Justin SB 5ed11fd9c7 GCE: don't rely on hostname being correct 
Distros that use systemd for DHCP often don't have the hostname
correct, due to e.g. the requirement for policy kit.

We don't rely on it being set correctly on other clouds; no real
reason to require it on GCP either!

Xiaoyu Zhong 002ddbb270 Alicloud: add hostname override 2019-10-16 21:53:40 +08:00
Michael Wagner bfe9b21213 fix(external-ccm): prevent core components to be misconfigured 
Previously when setting the external cloud controller manager
configuration the core components `kubelet`, `apiserver` and
`kubecontroller-manager` were configured to use the external cloud
controller manager. Without setting the feature flag
EnableExternalCloudController this lead to a cluster in which the
masters had the cloud controller taint
`node.cloudprovider.kubernetes.io/uninitialized` which prevents
essential pods, like dns-controller to not be scheduled and leaves a
cluster where worker nodes can't connect to the api server because they
cannot resolve its hostname.

Peter Rifel 3d8f57fa24 Dont set CriticalPodAnnotation feature gate in k8s 1.16 
The E2E tests are currently failing [0] due to this kubelet error [1]:

`F0818 22:43:57.642896    6424 server.go:179] unrecognized feature gate: ExperimentalCriticalPodAnnotation`

This feature gate was removed in Kubernetes 1.16 [2]

Change code from glog to klog 
We don't call klog.InitFlags yet, because that will cause a flag
redefinition error until we get everyone to stop using glog.  That
will happen when we update to k8s 1.13.

Justin Santa Barbara b208bd44b3 Create ExperimentalClusterDNS feature flag 
This currently just turns off validation of the kubelet cluster dns
flag, which should allow for experimenting with more complicated DNS
configurations such as local proxies, which may address shortcomings
of DNS retries with UDP.

Merge pull request #3809 from rdrgmnzs/hostnameOverride_use_hostname 
Automatic merge from submit-queue.

Let a user set a hostnameOverride when the cloud provider is aws.

Let a user use the hostname or set a hostnameOverride when the cloud provider is aws. This would allow for a more descriptive name to be used. The name of the hosts when using @hostname can be set by using a hook or some other method.
