2018-07-25runsc: Fix "exec" command when called without --pid-file.Nicolas Lacasse
When "exec" command is called without the "--detach" flag, we spawn a second "exec" command and wait for that one to start. We use the pid file passed in --pid-file to detect when this second command has started running. However if "exec" is called with no --pid-file flag, this system breaks down, as we don't have a pid file to wait for. This CL ensures that the second instance of the "exec" command always writes a pid-file, so the wait is successful. PiperOrigin-RevId: 206002403 Change-Id: If9f2be31eb6e831734b1b833f25054ec71ab94a6
2018-06-19runsc: Enable container creation within existing sandboxes.Kevin Krakauer
Containers are created as processes in the sandbox. Of the many things that don't work yet, the biggest issue is that the fsgofer is launched with its root as the sandbox's root directory. Thus, when a container is started and wants to read anything (including the init binary of the container), the gofer tries to serve from sandbox's root (which basically just has pause), not the container's.

2018-05-15Refactor the Sandbox package into Sandbox + Container.Nicolas Lacasse
This is a necessary prerequisite for supporting multiple containers in a single sandbox. All the commands (in cmd package) now call operations on Containers (container package). When a Container first starts, it will create a Sandbox with the same ID. The Sandbox class is now simpler, as it only knows how to create boot/gofer processes, and how to forward commands into the running boot process. There are TODOs sprinkled around for additional support for multiple containers. Most notably, we need to detect when a container is intended to run in an existing sandbox (by reading the metadata), and then have some way to signal to the sandbox to start a new container. Other urpc calls into the sandbox need to pass the container ID, so the sandbox can run the operation on the given container. These are only half-plummed through right now.

Detachable exec commands are handled in the client entirely and the detach option is not used anymore. PiperOrigin-RevId: 195181272 Change-Id: I6e82a2876d2c173709c099be59670f71702e5bf0
