Building and deploying a Java app with Docker, Google, Azure, and Octopus

The article details a step-by-step guide for deploying a Java application using a Continuous Integration (CI) and Continuous Delivery (CD) process, specifically focusing on utilizing Google Cloud Platform (GCP) and Microsoft Azure services. It describes building a Maven Java project and pushing its container image to the Google Container Registry (GCR) using the command line and gcloud tools. The process involves accessing GCR through Octopus Deploy to deploy the Java application to Azure Kubernetes Service (AKS). The guide outlines prerequisites, provides instructions for configuring tools, and covers the creation of a Kubernetes cluster on Azure, followed by deploying the application using YAML configurations in Octopus Deploy. Additionally, it explains how to set up Kubernetes monitoring with runbooks in Octopus Deploy, enabling organizational-level resource monitoring. The article concludes by encouraging readers to explore further insights in the Continuous Integration series.
