<p>I have this script to develop CI/CD pipeline using GitHub action. Pipeline's flow is like GitHub -> Docker Hub -> IBM Cloud Kubernetes.
I'm facing this issue for 2-3 days while running kubernetes set image command. Tried many things but no luck. And I'm kind a new at this GitHub Actions and Kubernetes. My script;</p>

<pre><code>on:
  push:
    branches:

    - name: Check docker login status
      if: failure()
      run: echo Docker login process failed. Please check the GitHub secrets and your credentials.

      #    - name: Build the Docker image

<p>And while executing it this is the error I'm facing;</p>

<p>Thanks in advance.</p>

<p>I think you need to check the <code>ibmcloud cs cluster-config &lt;cluster-name&gt;</code> output to ensure it's getting what you want. Unless you set the <code>IKS_BETA_VERSION=1</code> env var before running the getting the cluster config, you'll get kubeconfig and cert data downloaded to your local machine at $HOME/.bluemix/plugins/container-service/clusters/. If you use the <code>IKS_BETA_VERSION=1</code> env var, then you'll get the context/cluster/auth info in the default kubeconfig location of $HOME/.kube/config</p>
