7 .Canonical’s distribution of
Kubernetes
8 .Why Canonical Kubernetes?
Pure upstream, latest & greatest versions
Operates on AWS, Azure, GCE, OpenStack, VMWare, bare metal
Bare metal operations with MAAS
100% compatible with Google’s Kubernetes
Secured. TLS, Kernel Live patching, confinement
Upgradable between each Kubernetes Release
Cost effective at scale
9 .extensible by design

12 .CICD in Cloud Native
What are the basics?
What are the problem areas?
13 .CICD : A Basic Setup - Logical
1. Source Code (Repo)
2. Continuous Integration (CI)
3. Continuous Delivery (Cd)
4. Continuous Deployment (CD)
5. Runtime Environment

The Problem? The Benefit?
- Eliminate Internet Access - Fast Builds
- Large Images Slows - Fast Deploys
build-deploy-test loop - Fast build-deploy-test loop
- Empower “Airplane Mode”
17 .CICD : A Basic Setup - All-in-One
Goals:
1. Build Self Sufficient VM
2. Allow VM to be Ephemeral CICD
3. Restart VM and keep State All-in-One
Key Tools:
VM: Guest OS - Ubuntu
1. Multipass - launch vms
2. Microk8s - launch kubernetes multipass Native Hypervisor
Host Operating System
Laptop / Desktop / Workstation / Server
