Custom kubectl scripting in Octopus

Matthew Casperson's blog post delves into the flexibility and capabilities of using custom scripts in Octopus for Kubernetes deployments. It highlights the utility of writing scripts against kubectl through Octopus to leverage custom scripting tools and advanced Kubernetes properties. The post explains how to create reusable scripts by setting the KUBECONFIG environment variable, thus directing kubectl commands to specific Kubernetes targets. It emphasizes the benefits of referencing Docker images as additional packages in Octopus, allowing dynamic image version selection during deployment. The article also addresses the integration challenges posed by numerous platforms and tools, introducing the concept of Worker tool Docker images that encapsulate common open-source tools, enabling deployment processes to run in containerized environments. By configuring networking settings for Docker and Kubernetes clusters, the blog further demonstrates the practical application of Octopus in managing complex deployments. Overall, it underscores the extensive scripting capabilities provided by Octopus, supported by a rich set of variables and a comprehensive collection of Kubernetes and Docker tools.
