1 like411 views
The document is a presentation outlining the transition from Puppet to Kubernetes, detailing tools and resources available for users. Key topics include the introduction of Kubernetes, Helm, and Rook, along with a tool called Kream designed to simplify Kubernetes cluster setup. It emphasizes security controls in production environments and provides guidance on using command-line tools to manage Kubernetes configurations.

PuppetConf 2017: Zero to Kubernetes -Scott Coulton, Puppet
- 1. Zero to Kubernetes Scott Coulton Principal Software Engineer Puppet
- 3. The Team Greg Hardy Dave Try Mark Fuller Sheena Tharakanparampil Mark Willson Sinead Heverin Gert Drapers
- 4. This Talk What we will cover
- 5. So you're a Puppet user and you want to move to Kubernetes But where do you start ? 5
- 6. Agenda The Tools What has Puppet released and why ? Development From cluster changes to Helm chart deployments Production The end goal 6
- 7. Let's build some clusters. We will come back to them later 7
- 8. 8 The Tools
- 9. We wanted to build Full Kubernetes experience for our users. This needed to true for both Development and Ops 9
- 10. Kubernetes. ● Container orchestration ● Cloud native ● Pluggable container runtime ● Truly distributed application https://forge.puppet.com/puppetlabs/kubernetes 10
- 11. Helm. ● Kubernetes application packaging framework ● A standardised way to deploy complex applications ● Open source repo for public charts https://forge.puppet.com/puppetlabs/helm 11
- 12. Rook. (Coming soon) ● Block level storage for Kubernetes ● Built on ceph ● Deployed as a Helm chart ● Standardised storage layer between cloud and bare metal 12
- 13. How we help you move to Kubernetes efficiently 13 Development
- 14. Kubernetes is Complex. At Puppet we wanted to abstract Complexity where we can to make your life delivering your applications easier. 14
- 15. Enter Kream. (Kubernetes rules everything around me) https://github.com/puppetlabs/kream 15
- 16. Kream gives you. ● What we call Kubernetes in a box ● 3 nodes (You can build more it’s in the readme) ● Helm ● Rook 16
- 17. To build the Cluster. rake cluster_up 17
- 18. This is where it really counts 18 Production
- 19. Security is important. ● You want end to TLS ● You want your nodes to be in rbac groups ● Nodes should use bootstrap tokens 19
- 20. How is Puppet helping you with you security controls. 20
- 21. We have a tool to help https://github.com/puppetlabs/puppetlabs-kubernetes/tree/mas ter/tooling 21
- 22. This tool gives you. ● All your security controls are autogenerated ● The tool outputs to a hiera file 22
- 23. Commands: kube_tool.rb build_hiera FQDN, IP, BOOTSTRAP_CONTROLLER_IP, ETCD_INITIAL_CLUSTER, ETCD_IP, KUBE_API_ADVERTISE_ADDRESS, INSTALL_DASHBOARD # Pass the cluster params to build your hiera configuration kube_tool.rb help [COMMAND] 23 How to run it.
- 24. ./kube_tool.rb build_hiera kubernetes 172.17.10.101 172.17.10.101 "etcd-kube-master=http://172.17.10.101:2380,etcd-kube-replica-mast er-01=http://172.17.10.210:2380,etcd-kube-replica-master-02=http:/ /172.17.10.220:2380" "%{::ipaddress_enp0s8}" "%{::ipaddress_enp0s8}" true 24 How to run it.
- 25. Let’s do it live. 25
- 26. The hiera file is already in Kream. 26
- 27. Lets check our cloud deployment. 27
- 28. Questions. 28
