  1. Docker 101 Geoffrey Bachelet –@ubermuda

  2. Who's talking? • Geoffrey Bachelet • Stage1.io : continuous staging

    • Gustave.io : interactive staging • Freelance Developer / Trainer @ubermuda

  3. Container Engine? Based on the Linux kernel's LXC instructions Processes

    and resources isolation "chroot" on steroids / super lightweight VMs

  4. 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

  5. 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

  6. Image vs Container

  8. Container credit: http:/ /docs.docker.io/en/latest/terms/image/

  9. Create a container

  10. $  docker  run  -­‐i  -­‐t  stackbrew/ubuntu  /bin/bash   ! root@21d86a0b8387:/#

  11. Commit the container

  12. root@21d86a0b8387:/#  apt-­‐get  install  nginx   root@21d86a0b8387:/#  exit   ! $

     docker  ps  -­‐q  -­‐n  1   21d86a0b8387   ! $  docker  commit  21d86a0b8387  sflive/nginx   240198b750c3cc950c60005d6d24cae4fc2dbcc6c31e274574af68d4a2e8   ! $  docker  images   REPOSITORY            TAG                  IMAGE  ID   sflive/nginx          latest            240198b750c3

  13. root@21d86a0b8387:/#  apt-­‐get  install  nginx   root@21d86a0b8387:/#  exit   ! $
