Unable to connect aks cluster using github actions

Uday Kiran Reddy (ureddy) 96

I am trying to connect to cluster and create a namespace using github actions.
For that, I tried these steps.

In the link shared above, I first retrieved the azure service principal for connecting aks.

az ad sp create-for-rbac --name "myApp" --role contributor --scopes /subscriptions/<SUBSCRIPTION_ID>/resourceGroups/<RESOURCE_GROUP> --sdk-auth

And then, proceeded with the steps.
But, during namespace creation, I am getting error as below.

W1102 12:06:42.227952 3700 helpers.go:555] --dry-run is deprecated and can be replaced with --dry-run=client.
The connection to the server localhost:8080 was refused - did you specify the right host or port?
Error: Process completed with exit code 1.

Below is the github job failing.

name: Set the target Azure Kubernetes Service (AKS) cluster.
uses: azure/aks-set-context@v1
with:
creds: '${{ secrets.AZURE_CREDENTIALS }}'
cluster-name: ${{ env.CLUSTER_NAME }}
resource-group: ${{ env.CLUSTER_RESOURCE_GROUP }}

name: Deploy to Cluster
uses: azure/k8s-deploy@v1
with:
manifests: |
manifests/deployment.yml
manifests/service.yml
images: |
${{ env.REGISTRY_NAME }}.azurecr.io/${{ env.APP_NAME }}:${{ github.sha }}
imagepullsecrets: |
${{ env.SECRET }}
namespace: ${{ env.NAMESPACE }}

@Uday Kiran Reddy (ureddy) ,
Normally that error means some issue with the kube config file. It seems kubectl attempting to connect to localhost for the control plane server instead of actual AKS cluster.
Try to run az aks get-credentials -g <resourcegroupname> -n <aksclustername> --overwrite
Validate the output of : kubectl config current-context (Make sure it is set to right AKS cluster)

Regards,
Shiva.

I found the cause, the run step order and typos

After setting that, it is working,

- name: Set the target Azure Kubernetes Service (AKS) cluster. uses: azure/aks-set-context@v1 with: creds: '${{ secrets.AZURE_CREDENTIALS }}' cluster-name: ${{ env.CLUSTER_NAME }} resource-group: ${{ env.CLUSTER_RESOURCE_GROUP }}

Also, the acr container registry is being used here and creating a tag everytime using the short-ID of github commit.
How to update the deployment to use the new tag once the push is completed.

The below run task is using static yaml files only.

name: Deploy to Cluster
uses: azure/k8s-deploy@v1
with:
manifests: |
manifests/deployment.yml
manifests/service.yml
images: |
${{ env.REGISTRY_NAME }}.azurecr.io/${{ env.APP_NAME }}:${{ github.sha }}
imagepullsecrets: |
${{ env.SECRET }}
namespace: ${{ env.NAMESPACE }}

@ UdayKiranReddyureddy-2664 , using the latest image tag explicitly might be an option. Can you please check if this helps?

Is there any option like parameters or placeholders? Because latest tag won't update automatically.And there are other complications also

And the link you shared is about image push. But I am stuck at application deployment using yaml files
