jenkins pipeline agent step

Jenkins Pipeline's `agent` step is used to allocate a Jenkins agent (also known as a slave or node) to execute the stages of your pipeline. The `agent` step specifies where the pipeline should run, whether on the Jenkins master or on a specific agent with the required capabilities.

Here is an example of how to use the `agent` step in a Jenkins Pipeline:

pipeline {
    agent {
        // Specify the type of agent and its label
        label 'my-agent'
    }
    stages {
        // Define your pipeline stages here
        stage('Build') {
            steps {
                // Steps for the build stage
            }
        }
        stage('Test') {
            steps {
                // Steps for the test stage
            }
        }
        // Add more stages as needed
    }
}

In this example, the `agent` step specifies that the pipeline should run on an agent with the label `'my-agent'`. You can replace `'my-agent'` with the label of a specific agent you have configured in your Jenkins environment.

By using the `agent` step, you can distribute the workload of your pipeline across multiple agents, allowing for parallel execution of stages and better resource utilization.
