Docker 101 Geoffrey Bachelet –@ubermuda
Who's talking? • Geoffrey Bachelet • Stage1.io : continuous staging
• Gustave.io : interactive staging • Freelance Developer / Trainer @ubermuda
Container Engine? Based on the Linux kernel's LXC instructions Processes
and resources isolation "chroot" on steroids / super lightweight VMs
Host OS Hypervisor Guest OS Guest OS Guest OS Guest
OS App App App App Host OS Docker + LXC App App App App VMs vs Containers
VMs vs Containers LXC / Jails / Zones / etc
Uses the host's kernel Boots in seconds 0 overhead (almost) Easy to pass around Hypervisor Boots a complete OS Boots in minutes Guest OS' overhead Several Go images
Image vs Container

Create a container
$ docker run -‐i -‐t stackbrew/ubuntu /bin/bash ! root@21d86a0b8387:/#
Commit the container
root@21d86a0b8387:/# apt-‐get install nginx root@21d86a0b8387:/# exit ! $
