Java CI/CD: From Continuous Integration to Release Management

Java CI/CD: From Continuous Integration to Release Management

This post is part of a series that demonstrates a sample deployment pipeline with Jenkins, Docker, and Octopus.

This post is part of a series that demonstrates a sample deployment pipeline with Jenkins, Docker, and Octopus:

DevOps

In the previous blog post we used Octopus to build a Kubernetes cluster in AWS using EKS, and then deployed the Docker image created by Jenkins as a Kubernetes deployment and service.

However, we still don’t have a complete deployment pipeline solution, as Jenkins is not integrated with Octopus, leaving us to manually coordinate builds and deployments.

In this blog post, we’ll extend our Jenkins build to call Octopus and initiate a deployment when our Docker image has been pushed to Docker Hub. We will also create additional environments, and manage the release from a local development environment to the final production environment.

Install the Jenkins Plugins

Octopus provides a plugin for Jenkins that exposes integration steps in both freestyle projects and pipeline scripts. This plugin is installed by navigating to Manage Jenkins ➜ Manage Plugins. From here you can search for "Octopus" and install the plugin.

The Octopus plugin uses the Octopus CLI to integrate with the Octopus Server. We can install the CLI manually on the agent, but for this example, we’ll use the Custom Tools plugin to download the Octopus CLI and push it to the agent:

Configure the Octopus Server and Tools

We add the Octopus Server, our pipeline will connect with, by navigating to *Manage Jenkins ➜ Configure System *:
