The blog post by Robert Wagner discusses the integration of Azure Functions and Amazon's Lambda with the Octopus REST API and Subscriptions Feature to automate tasks beyond Octopus's built-in capabilities. It describes two specific examples of such integrations: managing unclaimed manual interventions in deployments and handling offline machines. For unclaimed interventions, a C# Azure Function regularly checks for unassigned manual tasks and sends SMS notifications using Twilio if they remain unaddressed for over a minute. For managing offline machines, another function is triggered by Octopus subscriptions when a machine becomes unavailable, deciding whether to delete the machine or take remedial action, with notifications sent via SMS. The post provides detailed setup instructions for both examples, including using the Octopus.Client library, configuring app settings, and testing the functions. It also highlights the use of external systems for potential full implementations and offers resources for further reading and code samples.
