- 11. Docker avoids hell's matrix www.scotas.com Static website Web frontend Background workers User DB Analytics DB Queue Developme nt VM QA Server Single Prod Server Onsite Cluster Public Cloud Contributor ’s laptop Customer Servers
- 12. Benefits for developers www.scotas.com ● Build once / Run anywhere* (finally!!) – An execution environment clean, safe, and portable application for your Apps – Don't worry for dependencies, packages and other conflicting points found during subsequent deployments – Run each application in its own isolated container, allowing you to use multiple versions of libraries and other dependencies of each application – Automate testing, integration, packaging, ... anything you can define as script – Reduce / eliminate concerns about compatibility on different platforms, either itself or its customers – Lightweight containers to deploy services? A virtual machine without the overhead of a virtualization? Commit / Rollback image? That's the power of Docker * Basically Linux 3.8+ and RH 2.6.32+
- 13. Importance for DevOps www.scotas.com ● Configure once / Run anything – Do all life cycle management more efficient, consistent and repeatable – Increase the quality of the code produced by developers – Eliminate inconsistencies between development, testing, production and customer environments – Support the separation of concerns – It significantly improves integration, speed and reliability in continuous integration environments (CD) – Because the containers are so light, costs, deployment, and portability issues associated with VMs disappear
- 14. Why it works?, separation of responsibilities www.scotas.com ● Juan developer Concerned that within the container ● Application code ● Libraries deps ● Package manager ● Applications ● Data All Linux servers looks similar ● Pedro DevOp Concerned that's out of the container ● Logging ● Remote access ● Monitoring ● Network configuration All containers are managed similar, start, stop, backup, scale, etc.
- 15. Digging in more technical stuff www.scotas.com Why – Run anywhere ● Any kernel release, 2.6.32+ ● Any Linux distribution ● Bare-metal, Virtual, Cloud or not ● Container and host with same architecture (x86/ARM/Sparc) – Run everything ● If run in a host, It run in a container ● For example any application running in Linux What – High level, lightweight VM ● Own process space ● Own network interfaces ● Can run as root ● Can have is own /sbin/init different from host ● <<Machine as container>> – Low level, run using chroot ● Do not require is own /sbin/init ● Container with isolated process ● Sharing kernel space with the host ● No hardware emulated drivers (without HVM or PVM) <<App as container>>
- 16.

- 17. Why containers are lightweight www.scotas.com Bins/ Libs App A Source App (Without the SO consuming memory, resources, or requiring restart) App A' Bin s/ App A Bins/ Libs App A’ Gue st OS Bins/ Libs Modified App Copy on write functionality allows storing only diffs between container A and container A’ VMs Each application, each copy of a application, and every small change at the application requires a new virtual machine App A Guest OS Bins/ Libs Copy of the App Without SO can share bins/libs App A Guest OS Guest OS VMs Containers

- 30. Things to avoid in Docker containers www.scotas.com ● Don’t ... – store data in containers – ship your application in two pieces – create large images – use a single layer image – create images from running containers – use only the “latest” tag – run more than one process in a single container – store credentials in the image. Use environment variables – run processes as a root user – rely on IP addresses
