It appears that 
.instanceRole
is undefined.
If I try setting 
instanceRoles
on my 
eks.Cluster
, I receive:
Copy code

Super confused. Setting 
instanceRole
on the 
eks.Cluster
works but breaks lots of other things (i.e. coredns cannot be pulled from ECR). Looking at the code for 
Cluster
, I see there is a 
eksRole
and a 
instanceRole
. Not sure what the difference is.
How are you supposed to give your k8s Pods access via IAM to AWS services?
s
Usually the best way is not to use instance role for your pods but to utilize something like https://github.com/uswitch/kiam
f
That's interesting but I'd like to get up and rolling without needing to integrate another whole service. There must be a way to do this without adding a new service.

Yeah I've seen that. Going to try the 
createNodeGroup
. I'm surprised how fragile this is.
Any idea if you can have 
deployDashboard: true,
when using 
createNodeGroup
?
I'm guessing deploying the dashboard is going to be problematic if you use 
createNodeGroup
because there are no nodes in the cluster. Unfortunately the dashboard code is not exposed as an API in the eks package either 😞
d
Isnt deployDashboard part of the cluster definition and not node group ?
f
Yes but from what I can tell, it will try to deploy the dashboard immediately.
d
Oh..havent tried that since we dont deploy the dashboard at all..It will be a good issue to file
f
It's done here: https://github.com/pulumi/pulumi-eks/blob/087f65501092b79e5b5fac7f138de4d0e215830f/nodejs/eks/cluster.ts#L634-L636. Given that no nodes are in the group, that will probably fail.
It'd be great if the dashboard was exposed as an API.
d
You can also try to spin up cluster with 
deployDashboard: false
and then change to 
true
in a second 
pulumi up
f
True. A bit annoying for spinning up new environments though.
Is there a Typescript hack to be able to get access to that createDashboard function?
d
True..you can also circumvent the whole thing by deploying dashboard through a helm chart as well..
Not a typescript expert 😞
f
Hmm, worth a shot. Guessing there's no examples for that?
d
Havent come across it

I'm trying
Copy code
new k8s.helm.v2.Chart("k8s-dashboard", {
    repo: "stable",
    chart: "kubernetes-dashboard",
    version: "1.10.1"
}, {providers: {kubernetes: k8sProvider}});
but I get
Copy code
Error: Command failed: helm fetch stable/kubernetes-dashboard --untar --version 1.10.1 --destination /tmp/tmp-13188EbwU1rymTPCU
    Error: chart "kubernetes-dashboard" matching 1.10.1 not found in stable index. (try 'helm repo update'). No chart version found for kubernetes-dashboard-1.10.1
According to https://hub.helm.sh/charts/stable/kubernetes-dashboard the latest version is either 1.10.1 or 1.5.2. I tried both and they both result in the above error.
Running 
helm fetch stable/kubernetes-dashboard --version 1.5.2
locally, it works.
Woah, ran it after running that fetch command locally and it worked!
