cli: azure/cli@v1 not working with azure/login@v1 on self-hosted runner

Hi,

I’m running self hosted runners on k8s using https://github.com/actions-runner-controller/actions-runner-controller, which doesn’t have az cli installed by default.

So in my workflow, I’m installing it using curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash as per MS’s documentation and signing in using azure/login@v1 and a service account which works fine, but when I’m running azure/cli@v1 right after, it gives the following errors:

ERROR: Please run 'az login' to setup account.
Error: Error: az cli script failed.

here is how the github job looks:

  preview:
    runs-on: self-hosted
    steps:
      - uses: actions/checkout@v2

      - name: Install az cli
        run: curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

      - uses: azure/login@v1
        name: Sign in to Azure
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}
          environment: azurecloud

      - uses: azure/cli@v1
        name: Run what-if
        with:
          inlineScript: |
            az deployment sub what-if --location ${{ env.RESOURCEGROUP_LOCATION }} \
              --template-file deploy/main.bicep

Any idea how to fix this?
