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

What we do..

1.0 launched on 3/11

300 + users registered in last 48hrs

Over 1300+ builds

Our Stack

Speed

Our uniqueness

…because of

…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?

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?

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?

What it really is, is this…

It is a VM without the overhead of a VM

VM vs Container

Docker 0.9 Shipped on 2/10

• 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?
