Move to Kubernetes 1.8 in terraform-kubernetes-installer about terraform-kubernetes-installer HOT 13 CLOSED

Pretty sure it's next on the list after integrating with the oci-flexolume-driver, oci-volume-provisioner and oci-cloud-controller-manager is complete.

from terraform-kubernetes-installer.

FYI, we just moved to 1.7.10.

from terraform-kubernetes-installer.

FYI, I used the terraform-kubernetes-installer today with the following variables in terraform.tfvars to successfully deploy a cluster in OCI:

etcd_ver          = "v3.2.2"
flannel_ver       = "v0.9.1"
k8s_ver           = "1.8.6"
k8s_dns_ver       = "1.14.5"
k8s_dashboard_ver = "1.8.2"

I noticed the OCI Cloud Controller Manager gets installed, but not the OCI FlexVolume Driver / OCI Volume Provisioner. I'm assuming I can install these manually? When will they be included in the terraform installer?

The default version of k8s_ver is now 1.8.5.

Also submit conformance results to CNCF as part of this move

running with k8s v1.8.3:

kubelet: Flag --require-kubeconfig has been deprecated, You no longer need to use --require-kubeconfig. This will be removed in a future version. Providing --kubeconfig enables API server mode, omitting --kubeconfig enables standalone mode unless --require-kubeconfig=true is also set. In the latter case, the legacy default kubeconfig path will be used until --require-kubeconfig is removed.

Validate docker logging and log accessibility is working as expected

I should have a PR ready tomorrow.

Confirmed that a cluster based on the following input variables works fine:

etcd_ver          = "v3.2.2"
flannel_ver       = "v0.9.1"
k8s_ver           = "1.8.6"
k8s_dns_ver       = "1.14.5"
k8s_dashboard_ver = "1.8.2"

I did run into an issue accessing the dashboard:

Error: 'tls: oversized record received with length 20527'
Trying to reach: 'https://10.99.18.3:9090/'

which you can work around by using the following modified URL (note the http instead of https in the URL):

http://localhost:8001/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/
