Bootstrap Tentacle installation with Powershell DSC

Shawn Sesna's article from October 2019 explains the process of automating the installation and configuration of Tentacle machines using Infrastructure as Code (IaC) and PowerShell Desired State Configuration (DSC) within Octopus Deploy environments. As organizations grow, manually installing Tentacles on numerous machines becomes impractical, prompting the need for IaC solutions that ensure consistency and predictability in deployments. The article provides a step-by-step guide on setting up the necessary components, such as the NuGet package provider and the OctopusDSC module, and configuring a Tentacle machine as a deployment target through a PowerShell script. It also highlights the importance of monitoring for configuration drift and utilizing Octopus Deploy's Machine Policy feature to automatically correct any deviations from the desired state, thereby maintaining the integrity of the infrastructure setup.
