Pulling the strings to containerise your life

The slides from Puppet Camp Melbourne 2016

Transcript

1. Pulling the string to containerise your environment
2. We will be looking at the different way you can use Puppet to help your journey to a continerised life. We spilt the talk into 2 segments • The last 6 months ( The birth of project Blueshift) • The new cutting edge stuff
3. About me Platform engineering lead @
4. Before we start. Why use Puppet for Containerisation ? Puppet allows you to define the state of a resource on a traditional server. The container eco system is no different. You still need to define state or we just end up back where we were before automation.
5. What does Puppet look like in the new world We are no longer just controlling resources and services !!! • We use custom type/providers to control API’s • Puppet can manipulate data for other systems to ingest • We can now query key/value stores dynamically to update data structures • We can use Puppet to auto generate application code
6. Docker Swarm
7. Docker Swarm • Docker Swarm is Docker’s open source container scheduler • Allows you to configure the key/value store of your choice • Built in HA for node failure • Supports Docker Compose • Supports Docker native networking (Overlay)
8. Swarm’s architecture
9. The modules to Build Swarm Garethr/Docker https://forge.puppet.com/garethr/docker Scottyc/Golang https://forge.puppet.com/scottyc/golang KyleAnderson/Consul https://forge.puppet.com/KyleAnderson/consul Scottyc/Docker_swarm https://forge.puppet.com/scottyc/docker_swarm
10. The Code For a full working demo of Docker Swarm https://github.com/scotty-c/puppet-demo
11. Docker UCP
12. Docker UCP • Docker’s Enterprise solution (Paid product) • Supports all the features of Docker Swarm • Gives you the option of using etcd or consul as the Key/value store • Comes with an integrated web ui • The easiest of the three schedulers to set up
13. UCP’s architecture
14. The modules to Build UCP Garethr/Docker https://forge.puppet.com/garethr/docker Puppetlabs/docker_ucp https://forge.puppet.com/puppetlabs/docker_ucp
15. The Code For a full working demo of Docker UCP https://github.com/scotty-c/ucp-demo
16. Kubernetes
17. Kubernetes • Google’s edition to the container world • Is open source • Well defined API ecosystem • Has multiple interfaces and methods of control • Self healing • Locks you into etcd and flannel
18. Kubernetes’s architecture
19. The modules to Build Kubernetes Garethr/Docker https://forge.puppet.com/garethr/docker Garethr/kubernetes https://forge.puppet.com/garethr/kubernetes
20. The Code For a full working demo of Kubernetes https://github.com/scotty-c/kubernetes-demo
21. What about storage persistence We have created HA clusters for our container eco system for compute failure. What about our data ?
22. Flocker
23. Flocker • Flocker allows us to set up standalone volumes for containers • Supports AWS (EBS), GCE (PD) and Openstack (Cinder)
24. Flocker’s architecture
25. The modules to Build Flocker scottyc/flocker In POC (if anyone in the community wants to help. Hit me up) stankevich/python https://forge.puppet.com/stankevich/python
26. The Code For a full working demo of Flocker https://github.com/scotty-c/flocker-puppet-poc
27. Other Apps we have used in our demo Code • Consul https://www.consul.io/ • Etcd https://coreos.com/etcd/docs/latest/ • Flannel https://coreos.com/flannel/docs/latest/ • Interlock https://github.com/ehazlett/interlock • Golang https://golang.org/ • Registrator https://github.com/gliderlabs/registrator
28. And on the Puppet Forge • Consul https://forge.puppet.com/KyleAnderson/consul • Etcd https://forge.puppet.com/cristifalcas/etcd • Flannel https://forge.puppet.com/cristifalcas/flannel • Golang https://forge.puppet.com/scottyc/golang
29. And even more we didn’t have time to get too • Mesos https://forge.puppet.com/deric/mesos • Rancher https://forge.puppet.com/puppetlabs/rancher • Rex Ray https://forge.puppet.com/emccode/rexray
30. Now the cool new stuff !!!!
31. puppetlabs/puppetlabs-image_build • Allows you to take your Puppet code and containerise with ease. • Very little dev work • Good bang for your buck
