Azure / login

I am currently set up my github action to do azure deployment":

jobs:
    build:
        runs-on: [self-hosted] 
        #container:
        #    image: mcr.microsoft.com/azure-cli:latest
        steps:
        - name: Login to Azure
          uses: azure/login@v2
          with:
                creds: '{"clientId":"${{ secrets.AZURE_CLIENT_ID }}","clientSecret":"${{ secrets.AZURE_CLIENT_SECRET }}","subscriptionId":"${{ secrets.AZURE_SUBSCRIPTION_ID }}","tenantId":"${{ secrets.AZURE_TENANT_ID }}"}'
        - name: Deploy ARM Template
          uses: azure/CLI@v2
          with:
                azcliversion: latest
                inlineScript: |
                    az account show

but it does not work for me: The problem is, azure/login required 'az' as tool to be installed on the runner

login/src/Cli/AzureCliLogin.ts

Line 19 in e9468ba

this.azPath = await io.which("az", true);

but azure/Cli required 'docker', see
https://github.com/Azure/cli/blob/99c7fe7a21b1dbe885695e092bf8451d20bac9c0/src/main.ts#L123

If I use image: mcr.microsoft.com/azure-cli:latest to run the job, I get error: "Error: Unable to locate executable file: docker". If I let the job run directly on my runner, I get error: "Error: Unable to locate executable file: az".

The question is: Why both action work in different way?

Same Error

Hi @wenwenchenbosch and @RS185734,

Before running azure/login, please ensure that you have installed azure-cli on your self-hosted runner. You can find instructions on how to use azure/login on your self-hosted runner in https://github.com/Azure/login?tab=readme-ov-file#login-with-system-assigned-managed-identity.

Additionally, make sure you have installed docker before running azure/cli.

It appears that the original design of azure/login and azure/cli may have been primarily for GitHub-hosted runners. With self-hosted runners, you are responsible for installing the necessary software yourself. Check out the Requirements for self-hosted runner machines.

We've noticed that many of our customers are using self-hosted runners, so we are continuously working to improve the user experience for self-hosted runner users. We will consider this as an improvement of our products.

Hi, the difference is that azure cli is started in a container whereas azure login uses the default installation of azure on the runner.

Closing the issue for now. Feel free to reopen it if you have any further questions.

Not able to use azure/login@v2 and azure/CLI@v2 in one job
