Shawn Sesna's post discusses the use of project triggers in Octopus Deploy to facilitate the deployment of applications to dynamically created targets, particularly useful in environments with scaling capabilities such as Kubernetes on Azure. The post explains a scenario where an Azure Resource Manager template is used to create a Kubernetes cluster, deploy the application, and then dismantle the cluster to save costs. The challenge arises when deployment targets are created as part of the deployment process, which can lead to steps being skipped since Octopus Deploy selects targets at the start of deployment. To resolve this, Sesna suggests adding a post-deployment script to register the Kubernetes cluster with Octopus and incorporating a Health Check step to ensure new targets are included. This allows the deployment process to recognize and deploy successfully to newly created targets.
