Understanding the Pipeline Execution Error

When attempting to run a pipeline, you may encounter an error. There are two primary solutions to this issue:

1. Request a parallelism grant by following the link provided in the error log.
2. Set up your own agent and configure your local machine to act as a server by following the instructions detailed in this article.

Steps to Create Your Agent

To begin, navigate to your project in Azure DevOps. Click on Project Settings and select Agent Pools from the left sidebar.

Next, choose Default from the options available.

Now, let’s proceed to create your agent.

A pop-up window will appear. Select your operating system, download the agent, and follow the subsequent steps. In this instance, I selected Windows and opened the command shell—ensure you run it as an administrator.

Create a new directory named agent and navigate to it.

Next, input the path of the agent you have just downloaded.

Run the configuration command, which will prompt you for a Personal Access Token (PAT). Press enter first, and then input the PAT as outlined in the following steps.

To generate a PAT, go to Azure DevOps and click on User Settings.

Once created, copy the PAT.

Now, paste the PAT and respond with "N" for the subsequent commands.

Execute the following commands:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine

Finally, execute the command: ./run.cmd. Your machine is now set up to listen for jobs from the pipeline.

You will also need to install Docker Desktop and keep it open while running your pipeline.
