Variable as Namespace about k8s-deploy

[thesattiraju]

You need to use namespace like ${{ env.NAMESPACE }} instead of $NAMESPACE. Given that the environment variable is not available in that context, it failed because of that.

When you use it like ${{ env.NAMESPACE }} this value gets replaced with the actual value of the variable and passed to the action.

That didn't do the trick, it seems to ignore when I do that:

/usr/bin/kubectl apply -f /tmp/Deployment_revio-calendar-frontend_1592492995710,/tmp/Service_revio-calendar-frontend_1592492995710,/tmp/Ingress_revio-calendar-frontend-ingress_1592492995710 --namespace default
deployment.extensions/revio-calendar-frontend created
error: the namespace from the provided object "dev" does not match the namespace "default". You must pass '--namespace=dev' to perform this operation.
service/revio-calendar-frontend created
##[error]Error: error: the namespace from the provided object "dev" does not match the namespace "default". You must pass '--namespace=dev' to perform this operation.

This was with the following config:

    - name: 'Deploy to Kubernetes'
          uses: Azure/k8s-deploy@v1
          with:
            namespace: ${{ env.NAMESPACE }}
            manifests: |
              manifests/deployment.yml
              manifests/service.yml
              manifests/ingress-dev.yml
            images: |
              ${{ secrets.REGISTRY_LOGIN_SERVER }}/revio-calendar-frontend:${{ github.sha }}
            imagepullsecrets: |
              c1-k8s-secret
              - uses: actions/checkout@v2

You have to declare that environment globally. I suppose that value is not added to the env context because of where you're declaring it.

Consider adding an environment section at the workflow level. Something like this: https://github.com/Azure/actions-workflow-samples/blob/master/Kubernetes/build-and-deploy-docker-image-aks-using-manifests.yml#L15
