Transcript

1. Advance AWS Meetup - @okta– 05/06/2014 Brief introduction to Docker & AWS deployment Victor Vieux, Docker Inc. @vieux
2. What is docker ?
3. The Matrix From Hell
4. Another Matrix From Hell
5. Solution: the intermodal shipping container
6. Solved!
7. Solution to the deployment problem: the Linux container
8. Solved!
9. High level approach: lightweight VM •  own process space •  own network interface •  can run stuff as root •  can have it’s own /sbin/init (different from the host) “Machine Container”
10. Low level approach: chroot on steroids •  can also not have it’s own /sbin/init •  container = isolated process(es) •  share kernel with the host “Application Container”
11. What’s really docker ?
12. user@dockerhost:~$ docker run –it ubuntu bash root@1b55513ade2e:/# ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 18048 1960 ? Ss 08:35 0:00 bash root 13 0.0 0.0 15276 1140 ? R+ 08:35 0:00 ps aux user@dockerhost:~$ docker run –d crosbymichael/redis 699eb403b54b user@dockerhost:~$ docker inspect 699eb403b54b "IPAddress": "172.17.0.2", "Ports": { ”6379/tcp": [{ "HostIp": "0.0.0.0", "HostPort": "49200" }] } Runtime for Linux containers
13. Standard format for containers and a place to share them •  Fetch an image from the public registry with “docker pull” •  Enter an image with “docker run“ and do some changes •  Record those changes with “docker commit”, repeat as many times as needed •  And then share the result with “docker push” on the public registry, or a private one
14. Deployment on:
15. EC2 – Amazon Linux •  Choose the last Amazon Linux AMI •  Launch & ssh into the instance sudo yum install –y docker sudo service docker start •  Docker 0.9 is installed
16. EC2 – Ubuntu •  Choose a 64Bit Ubuntu image •  In the Launch Instance Wizard, set #include https://get.docker.io as User data •  Launch & ssh into the instance •  Wait for the cloudinit script to finish •  Last version of docker is installed
17. EC2 – Ubuntu - Testing •  edit /etc/default/docker DOCKER_OPTS="-H 0.0.0.0:4243” •  Restart the docker daemon sudo service docker restart •  Open the port 4243 in the EC2 console •  On you laptop, set DOCKER_HOST $>export DOCKER_HOST=<EC2_ip>:4243 $>docker run fedora:20 ls
18. Elastic Beanstalk 1
19. Elastic Beanstalk 2 3
