What actions do you take when setting up and launching Jenkins for project build and deployment automation?

To set up and run Jenkins for automating the build and deployment of projects, I usually follow these steps:

1. Install Jenkins on a server (for example, via a package manager or Docker).
2. Configure access: create users and roles, set up security.
3. Install necessary plugins (Git, Docker, Pipeline, etc.) for integration with project tools.
4. Create a new Jenkins Job or Pipeline:
   • Configure the source code (Git repository).
   • Define build steps (e.g., compilation, running tests).
   • Set up deployment stages (copying artifacts, running scripts on the server).
5. Configure triggers for automatic start (on commit, on schedule).
6. Test and debug the pipeline.
7. Monitor task execution and logs.

Example of a simple Jenkins Pipeline in Groovy:

pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                git 'https://github.com/user/repo.git'
            }
        }
        stage('Build') {
            steps {
                sh './build.sh'
            }
        }
        stage('Deploy') {
            steps {
                sh './deploy.sh'
            }
        }
    }
}
