But in this demo, were pushing to an external registry (docker.io), so we need to set up a Secret with our registry details. # Build the application first using Maven, # Inject the JAR file into a new container to keep the file small, --from=build /app/target/hello-java-*.jar /app/app.jar, docker.io/monodot/hello-java-spring-boot:latest, # Expect a local directory to be streamed to OpenShift as a build source, # Find the image build instructions in ./Dockerfile, // https://raw.githubusercontent.com/redhat-cop/container-pipelines/master/basic-spring-boot/Jenkinsfile, "https://github.com/redhat-cop/pipeline-library.git", // The name you want to give your Spring Boot application, // Each resource related to your app will be given this name, // Use the 'maven' Jenkins agent image which is provided with OpenShift, // This uploads your application's source code and performs a binary build in OpenShift, // This is a step defined in the shared library (see the top for the URL), // (Or you could invoke this step using 'oc' commands!). In this tutorial we will learn how to install Jenkins, Docker, install required Jenkins plugins for docker, run automatic Docker Build with Dockerfile using Jenkins Pipeline, pushing the docker Image to AWS ECR. To push an image into a staging or production environment, a common style is to update a predefined tag such as latest in the registry.

The error happens because the Dockerfile is not found.

Spring Boot - Probably the most popular Java framework. You should pass in a registry URL. Build a Java container CI/CD pipeline with Concourse: More safely, you can use the withRun method, which automatically stops the container at the end of a block: The above simply starts a container running a test MySQL database and runs a regular build while that container is running. 2022 Brain4ce Education Solutions Pvt.
