Building a Docker image in Jenkinsfile and publishing to ECR

Terence Wong's post provides a comprehensive guide on setting up a Jenkins Pipeline to build and push a GitHub repository to Amazon Elastic Container Registry (ECR), emphasizing the use of a Jenkinsfile to streamline the process. The guide outlines the prerequisites, including accounts for AWS, Jenkins, and GitHub, and details the necessary steps for configuring AWS, Jenkins, and GitHub to facilitate the continuous integration pipeline. Key components include creating AWS access keys and ECR repositories, installing essential Jenkins plugins, and setting up a GitHub webhook for automated build triggers. The Jenkinsfile, central to this process, specifies stages such as cloning, building, testing, and deploying the image, which is then pushed to the ECR tagged with the Jenkins build number. The post concludes by highlighting the versatility of the Jenkinsfile for other container registries and suggesting tools like Octopus Deploy for further deployment, while also inviting readers to explore additional resources and webinars on related topics.
