This was such a good resource in Docker that it would be a shame to lose it. Unfortunately, we can't just link to the corresponding information in the Docker project as a number of aspects are bound to be different here.

libcontainer principles
In the design and development of libcontainer we try to follow these principles:
(Work in progress)
- Don't try to replace every tool. Instead, be an ingredient to improve them.
- Less code is better.
- Less components is better. Do you really need to add one more class?
- 50 lines of straightforward, readable code is better than 10 lines of magic that nobody can understand.
- Don't do later what you can do now. "//FIXME: refactor" is not acceptable in new code.
- When hesitating between 2 options, choose the one that is easier to reverse.
- No is temporary, Yes is forever. If you're not sure about a new feature, say no. You can change your mind later.
- Containers must be portable to the greatest possible number of machines. Be suspicious of any change which makes machines less interchangeable.
- The less moving parts in a container, the better.
- Don't merge it unless you document it.
- Don't document it unless you can keep it up-to-date.
- Don't merge it unless you test it!
- Everyone's problem is slightly different. Focus on the part that is the same for everyone, and solve that.
