Error running devspace

[joshughes]

Just trying to start my first project...

Just set up using all the default options.

Kubectl works okay for my local K8 Cluster

Using Docker For Mac Kubernetes

On MacOS using v1.0.3

I'm getting the same issue as well on Docker for Mac with Kubernetes.

Thanks for reporting the issue. That should be easy to fix. I have a couple of questions to narrow the problem down:

1. Are you using Minikube?
2. If you look at PROJECT/.devspace/config.yaml: Is there cluster.useKubeConfig == true?
3. If you look at ~/.kube/config: Is there an entry in clusters[*].certificate-authority-data or clusters[*].certificate-authority? (please do not post the contents of the file publicly, as it may contain sensible secret keys)
4. What is the output of running echo $HOME?

[geekflyer]

Same error message here.
My answer to your questions above:

1. No
2. my config.yaml:

➜  foobar cat ./.devspace/config.yaml    
cluster:
  useKubeConfig: true
devSpace:
  portForwarding:
  - labelSelector:
      release: myapp
    portMappings:
    - localPort: 80
      remotePort: 80
    resourceType: pod
  release:
    name: myapp
    namespace: myapp
  sync:
  - containerPath: /app
    labelSelector:
      release: myapp
    localSubPath: ./
    resourceType: pod
    uploadExcludePaths:
    - Dockerfile
    - .devspace/
    - chart/
    - node_modules/
images:
  default:
    build:
      engine:
        docker:
          enabled: true
    name: myapp
    registry: default
registries:
  default:
    url: gcr.io
services:
  tiller:
    release:
      namespace: myapp
version: v1

3. yes, lot's of certificate-authority-data entries for the gke clusters I use
4. /Users/christian

Additional context: I'm using GKE and things like kubectl get pods just work fine with the current cluster I'm connected to. The kubeconfig entries were auto-generated via gcloud container clusters get-credentials <my_cluster>.

If I were to guess I suspect you have problems dealing with the way gke clusters are being authenticated against (it uses gcloud as credential helper / auth provider with short-lived access tokens etc.)

[LukasGentele]

Yes, I think you are completely right. That was the problem. I did not ship the google cloud auth plugin for the kubectl go-client. I am already testing a fix. Thank you for all the details!

@joshughes, @geekflyer, @andrewrothman: I just released v1.0.4 with several fixes for google kubernetes engine. You can upgrade your devspace version with: devspace upgrade
Let me know if this release works for you or if there are any other issues.
