11. The Usual Problems • Tools are hard to learn. • Improve workflows • Standardization • On-boarding New Projects • On-boarding New Engineers • Infrastructure lives with the Application Code • Secret Management • Permissions, Controls, Processes • Observability • Infrastructure Management https://github.com/ashleymcnamara/gophers
12. Introducing Shippy
13. 13 Docker • Build and Push image to AWS ECR • Login to AWS ECR Kubernetes • Process YAML templates using Kontemplate. • Deploy the correct manifests to the correct cluster.

16. 16 16 Go Modules • Cobra - commands • Viper - configuration • AWS SDK • Docker • Kubernetes https://github.com/ashleymcnamara/gophers
17. Learnings • Keep it modular. Separate commands from implementation. • Read the code of tools. • Expect to swap out tools • Make it easy to upgrade. https://github.com/ashleymcnamara/gophers
