3. Shippable helps developers ship code faster by
providing a hosted CI/CD service that automates
builds, tests & deployment
What we do..

4. 1.0 launched on 3/11
300 + users registered in last 48hrs
Over 1300+ builds
We just Shipped 1.0

5. Our Stack

6. Speed
Simplicity
$
Our uniqueness

7. …because of

8. …that can be manipulated using standard operations
and run consistently on virtually any hardware platform
An engine that enables any payload to be encapsulated as
a lightweight, portable, self-sufficient container…
What is Docker?

9. Build once…(finally) run anywhere
– A clean, safe, hygienic and portable runtime environment for your app.
– No worries about missing dependencies, packages and other pain
points during subsequent deployments.
– Run each app in its own isolated container, so you can run various
versions of libraries and other dependencies for each app without
worrying
– Automate testing, integration, packaging…anything you can script
– Reduce/eliminate concerns about compatibility on different platforms,
either your own or your customers.
Why devs care?

10. Configure once…run anything
– Make the entire lifecycle more efficient, consistent, and repeatable
– Increase the quality of code produced by developers.
– Eliminate inconsistencies between development, test, production, and
customer environments
– Support segregation of duties
– Significantly improves the speed and reliability of continuous deployment
and continuous integration systems
– Because the containers are so lightweight, address significant performance,
costs, deployment, and portability issues normally associated with VMs
Why ops cares?

11. What it really is, is this…
It is a VM without the overhead of a VM

13. Docker 0.9 Shipped on 2/10

14. • Execution drivers
– Support for multiple isolation tools
– OpenVZ, systemd-nspawn, libvirt-lxc, libvirt-sandbox, qemu/kvm, BSD
Jails, Solaris Zones
• New default driver : libcontainer
– Alternative to LXC which was default until now
– Claimed to be more stable
– Better access to kernel’s container API
• namespaces, control groups, capabilities, apparmor profiles, network interfaces
and firewalling rules
– No cross Linux version side-effects
What’s new?
