- 8. Loading is a bit faster 8
- 10. Virtual Machines vs Containers 10
- 13. Docker Hub 13
- 14. Why use Docker? • Package an application with it’s dependencies • Dev environment behaves exactly like production • Less overhead means more deployments on a server • Deploy the same container in different clouds • Not just for cloud computing • Docker has standardized container formats • It’s open source 14
- 15. Some other Docker Use Cases • Simulate deployed environment during development – Each container simulates a machine • Share containers between developers – Database containers with sample data • Also use in the (automated) QA environment – Build containers with compilers and libraries • Also use in the CI environment 15
- 17. Useful docker image commands • docker images • docker pull <image name> • docker build –t <image name> <folder> • docker run <image name> • docker rmi <image id> • docker rmi $(docker images -q -f dangling=true) 17
- 18. Useful docker container commands • Docker ps • docker logs <container name> • docker stop <container name> • docker start <container name> • docker kill <container id> • docker rm <container id> • docker rm $(docker ps -a -q) 18

Editor's Notes

- A single lift takes 40 tons of cargo https://www.flickr.com/photos/glynlowe/14369663877
- Ships where not very efficient when loading/unloading
- A lot of people were needed to move cargo in small units
- Large container ships move unknown cargo very efficiently https://www.flickr.com/photos/rhemkes/15398653092
- Loading is much more efficient because of standard container sizes https://www.flickr.com/photos/anaulin/1047673820

- Initial release13 March 2013
- Containers are based on Linux namespaces and cgroups Namespaces create separation The root can see everything Containers can only see things in their own namespace Existed before Docker Docker just makes things easier https://www.flickr.com/photos/prettybipolar/6938332165/
- Contains many ready to use images Upload your own
- A Docker file to create an image with NodeJS https://www.flickr.com/photos/nyuhuhuu/4443886636/
