Unable to connect to tiller on AKS from within cluster

[tirumaraiselvan]

I develop Gitkube (https://github.com/hasura/gitkube). Gitkube is a tool that builds apps INSIDE the cluster and deploys it. It supports installing helm charts.

I am seeing an issue on AKS which does not happen on GKE.

On GKE, everything is fine. When I do helm version from inside the gitkubed pod, I get expected results

Client: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}

On AKS though the story is different. helm version does not resolve tiller.

Output of helm version (note that this is run from inside a pod on the cluster):

$ helm version
Client: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}

Stuck finding server version

Output of kubectl version:

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"8", GitVersion:"v1.8.7", GitCommit:"b30876a5539f09684ff9fde266fda10b37738c9c", GitTreeState:"clean", BuildDate:"2018-01-16T21:59:57Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.6", GitCommit:"9f8ebd171479bec0ada837d7ee641dec2f8c6dd1", GitTreeState:"clean", BuildDate:"2018-03-21T15:13:31Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"linux/amd64"}

Cloud Provider/Platform (AKS, GKE, Minikube etc.):

AKS v1.9.6

I should mention, when I try helm upgrade on a chart I get:

Error: forwarding ports: error upgrading connection: Upgrade request required

[tirumaraiselvan]

From kubernetes/helm:

It seems helm does a port forward with tiller for communication:

kubectl -n kube-system port-forward my-tiller-pod 44134:44134

This throws the same error:

Error: forwarding ports: error upgrading connection: Upgrade request required

Is it a firewall issue with the pod network?

Probably a duplicate of #434

All (in all regions) new cluster creates should be patched with the fix. thanks for your patience, please report if you still see issues. Existing clusters will eventually get patched.

[tirumaraiselvan]

Yes it works now. Thanks!
