by Here is an example of Jenkins CI script for building a Docker image. This assumes you have the Jenkins Docker plugin installed and configured. Make sure you replace placeholder values with your actual values.
package main
pipeline {
agent any
environment {
DOCKER_IMAGE_NAME = "your-docker-image-name"
DOCKER_REGISTRY_URL = "your-docker-registry-url"
DOCKER_REGISTRY_CREDENTIALS = "your-docker-registry-credentials-id"
}
stages {
stage('Build Docker Image') {
steps {
script {
// Authenticate with Docker registry
docker.withRegistry(DOCKER_REGISTRY_URL, DOCKER_REGISTRY_CREDENTIALS) {
// Build Docker image
docker.build(DOCKER_IMAGE_NAME)
// Push Docker image to registry
docker.image(DOCKER_IMAGE_NAME).push()
}
}
}
}
}
}
This script defines a Jenkins pipeline with a single stage (Build Docker Image). The docker.withRegistry block is used to authenticate with the Docker registry using the specified credentials. Inside this block, the Docker image is built using docker.build, and then it’s pushed to the registry using docker.image(...).push().
Make sure to replace the placeholder values (your-docker-image-name, your-docker-registry-url, your-docker-registry-credentials-id) with your actual values. Also, ensure that the Jenkins Docker plugin is installed, and the Jenkins user has the necessary permissions to interact with Docker.
Note: The Docker plugin for Jenkins is just one way to interact with Docker in Jenkins. Depending on your Jenkins setup, you might need to use different plugins or approaches. Adjust the script accordingly based on your Jenkins configuration.
