The key is that "containers" don't actually exist -- they're just processes running under a variety of different namespaces.

- MaxBarraclough 6y agoIt's true that Docker isn't a first-class abstraction at the level of the Linux kernel, but BSD has jails, and Solaris has Zones. This is important in some respects, but I don't see that it informs things here. Containers are still 'a thing' regardless of how they're implemented.
- __jem 6y agoCurious to learn more about how jails + zones are implemented. In Linux land, I find the notion that containers are a coherent abstraction really hinders developers from understanding how their application is deployed.
