Deploying to Tomcat from Octopus Deploy

Octopus Deploy offers a set of deployment steps that facilitate the deployment of Java packages to Java web servers on Linux, specifically targeting the deployment of WAR files to a Tomcat server. The process involves building the WAR file using Maven, packaging it into a ZIP file compatible with Octopus Deploy’s versioning standards, and pushing it to the Octopus Deploy repository using the CLI tool. The deployment environment and deployment target, which represent the servers receiving the deployment, must be set up, with a focus on utilizing SSH for communication and ensuring necessary permissions. The deployment process involves executing deployment steps using Octopus’ Calamari engine, which requires Mono for running on Linux, although future updates aim to streamline this with .NET Core. Limitations include the inability to modify configuration files within WAR packages during deployment, but improvements are anticipated to enhance Java support in Octopus Deploy, along with potential CI server add-ons for automating deployment processes.
