Shawn Sesna's blog post from April 2021 describes how to deploy Octopus Deploy workers within a Kubernetes cluster using the Tentacle image, offering a scalable solution through a new Kubernetes-based worker introduced in August 2024 that allows for optimized infrastructure use via autoscaling. The guide explains the process of creating a worker pool and an external feed to deploy images from sources like Docker Hub, Artifactory, or Nexus, and details the setup of a runbook for deploying Kubernetes containers. The post emphasizes the importance of configuring deployment and container sections, including naming and environment variables essential for integrating the workers with an Octopus instance. It concludes with instructions on executing the runbook and verifying its functionality through upgrading Calamari on the deployed workers, reflecting on the effectiveness of using Octopus Deploy within Kubernetes for efficient and managed deployments.
