- Ships where not very efficient when loading/unloading
- A lot of people where 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/
- Not everything is namespaced yet Users are not => security https://www.flickr.com/photos/kewl/8576064449
- Contains many ready to use images Upload your own

- Containers should run one main executable. It stop and the container is done The main program receives a SIGTERM signal when the container needs to stop
