Using GitLab feeds with Octopus Deploy

The article by Shawn Sesna explores how to integrate GitLab's built-in registries as external feeds for deploying projects with Octopus Deploy, offering an alternative to Octopus's built-in repository for those seeking cross-space solutions without duplication. It details the use of GitLab's package and container registries, specifically covering how to configure Maven and NuGet package registries and a Docker container registry to work with Octopus Deploy. The article provides step-by-step instructions for setting up these registries, including adding authentication mechanisms and defining build definitions using YAML configuration files for both Java and .NET applications. By demonstrating with example applications like PetClinic for Maven and OctoPetShop for NuGet, the text illustrates how artifacts are compiled, packaged, and uploaded to the registries, which can then be added as external feeds in Octopus Deploy to streamline deployment processes.
