7b0e96f1f4 Manually pass the env to docker-init instead of relying on lxc to pass it 2013-04-16 14:32:50 -07:00

5e1a975b48 Use ip to setup the gateway in sysinit.go
ip from iproute2 replaces the legacy route tool which is often not
installed by default on recent Linux distributions.

The same patch has been done in network.go and is re-used here.

58a2294260 Implemented a self-injecting process wrapper that runs inside the container
- Before starting the container, docker injects itself inside the container by mount binding the dockerd binary into /sbin/init
- Instead of running the user process directly inside the container, we run /sbin/init targetprocess [args...]
- When docker is run as /sbin/init (e.g. argv[0] == "/sbin/init"), then its own sys init code kicks in
- The sys init code will be responsible for setting up the process environment prior to its execution (setuid, networking, ...).
- Finally, docker's sys init will exec() the container's process, thus replacing itself with the target binary (which will be running as pid 1)
