* Support multiple networksbaude2018-07-12
| | | | | | | | | | | | | This is a refresh of Dan William's PR #974 with a rebase and proper vendoring of ocicni and containernetworking/cni. It adds the ability to define multiple networks as so: podman run --network=net1,net2,foobar ... Signed-off-by: baude <bbaude@redhat.com> Closes: #1082 Approved by: baude
* Add --volumes-from flag to podman run and createumohnani82018-07-09
| | | | | | | | | | podman now supports --volumes-from flag, which allows users to add all the volumes an existing container has to a new one. Signed-off-by: umohnani8 <umohnani@redhat.com> Closes: #931 Approved by: mheon
* Remove per-container CGroup parentsMatthew Heon2018-07-06
| | | | | | | | | | | | | | | | | | | Originally, it seemed like a good idea to place Conmon and the container it managed under a shared CGroup, so we could manage the two together. It's become increasingly clear that this is a potential performance sore point, gains us little practical benefit in managing Conmon, and adds extra steps to container cleanup that interfere with Conmon postrun hooks. Revert back to a shared CGroup for conmon processes under the CGroup parent. This will retain per-pod conmon CGroups as well if the pod is set to create a CGroup and act as CGroup parent for its containers.

* libpod/container: Replace containerState* with containerPlatformStateW. Trevor King2018-07-05
| | | | | | | | | | | | | | | This way we don't need to stub in structures for other OSes (e.g. the Darwin stub in a Linux-only file). Matthew was concerned about errors unmarshalling, say, a Linux state object on a Windows box [1], but we can address that in checks when loading the database [2].

* Add `podman container cleanup` to CLIDaniel J Walsh2018-06-29
| | | | | | | | | | | | | When we run containers in detach mode, nothing cleans up the network stack or the mount points. This patch will tell conmon to execute the cleanup code when the container exits. It can also be called to attempt to cleanup previously running containers.

* Convert bind mounts to use DB fieldMatthew Heon2018-03-08
| | | | | | | | | | | | | | | Refactors creation of bind mounts into a separate function that can be called from elsewhere (e.g. pod start or container restart). This function stores the mounts in the DB using the field established last commit. Spec generation now relies upon this field in the DB instead of manually enumerating files to be bind mounted in.
