- 8. @bridgetkromhout #hashiconf Namespaces Cgroups Not a real thing. An application delivery mechanism with process isolation based on several Linux kernel features. • PID • Mount • Network • UTS • IPC • User • Cgroup • Memory • CPU • Blkio • Cpuacct • Cpuset • Devices • Net_prio • Freezer (what a process can see) (what a process can use) What is a container?
- 9. @bridgetkromhout #hashiconf consistent development repeatable deployment containers solve problems
- 10. containers solve problems @bridgetkromhout #hashiconf don’t all
- 11. @bridgetkromhout #hashiconf once upon a time…

- 19. @bridgetkromhout #hashiconf Portable Public, private, hybrid, multi-cloud Extensible Modular, pluggable, hookable, composable Self-healing Auto-placement, auto-restart, auto-replication, auto-scaling Kubernetes: a choice for orchestration
- 23. @bridgetkromhout #hashiconf Deploy your applications quickly and predictably Scale your applications on the fly Roll out new features seamlessly Limit hardware usage to required resources Kubernetes: empowering you to do more
- 24. @bridgetkromhout #hashiconf “day 2 k8s” - what do we mean? 1.You’re sold on k8s; what’s next? 2.necessarily opinionated… 3.…yet giving you info to decide.
- 25. @bridgetkromhout #hashiconf operable k8s: next steps -Getting started with Terraform & AKS -Managing configs with Helm & apps with Draft -Event-driven scripting with Brigade & Kasti
- 26. @bridgetkromhout #hashiconf Providers include Azure and Azure Stack. Deploy k8s clusters, pods, and services! https://registry.terraform.io/search?q=azurerm Terraform & Azure
- 27. @bridgetkromhout #hashiconf Terraform Module Registry and Microsoft Azure
- 29. @bridgetkromhout #hashiconf Simplify the deployment, management, and operations of Kubernetes Work how you want with open- source APIs Scale and run applications with confidence Focus on your containers not the infrastructure Azure Kubernetes Service (AKS)

- 38. @bridgetkromhout #hashiconf Simple app development and deployment – into any Kubernetes cluster Simplified development Using two simple commands, developers can now begin hacking on container-based applications without requiring Docker or even installing Kubernetes themselves Language support Draft detects which language your app is written in, and then uses packs to generate a Dockerfile and Helm Chart with the best practices for that language Draft
- 39. @bridgetkromhout #hashiconf Run scriptable, automated tasks in the cloud — as part of your Kubernetes cluster Simple, powerful pipes Each project gets a brigade.js config file, which is where you can write dynamic, interwoven pipelines and tasks for your Kubernetes cluster Runs inside your cluster By running Brigade as a service inside your Kubernetes cluster, you can harness the power of millions of available Docker images Brigade
