* auto updatesValentin Rothberg2020-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to auto-update containers running in systemd units as generated with `podman generate systemd --new`. `podman auto-update` looks up containers with a specified "io.containers.autoupdate" label (i.e., the auto-update policy). If the label is present and set to "image", Podman reaches out to the corresponding registry to check if the image has been updated. We consider an image to be updated if the digest in the local storage is different than the one of the remote image. If an image must be updated, Podman pulls it down and restarts the container. Note that the restarting sequence relies on systemd. At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT" environment variables and stores it verbatim in the container's label. This variable is now set by all systemd units generated by `podman-generate-systemd` and is set to `%n` (i.e., the name of systemd unit starting the container). This data is then being used in the auto-update sequence to instruct systemd (via DBUS) to restart the unit and hence to restart the container. Note that this implementation of auto-updates relies on systemd and requires a fully-qualified image reference to be used to create the container. This enforcement is necessary to know which image to actually check and pull. If we used an image ID, we would not know which image to check/pull anymore.

* add default network for apiv2 createBrent Baude2020-03-06
| | | | | | | | | | | | | during container creation, if no network is provided, we need to add a default value so the container can be later started. use apiv2 container creation for RunTopContainer instead of an exec to the system podman. RunTopContainer now also returns the container id and an error. added a libpod commit endpoint. also, changed the use of the connections and bindings slightly to make it more convenient to write tests.

* Remove ImageVolumes from databaseMatthew Heon2020-02-21
| | | | | | | | | | | | | | Before Libpod supported named volumes, we approximated image volumes by bind-mounting in per-container temporary directories. This was handled by Libpod, and had a corresponding database entry to enable/disable it. However, when we enabled named volumes, we completely rewrote the old implementation; none of the old bind mount implementation still exists, save one flag in the database. With nothing remaining to use it, it has no further purpose. Signed-off-by: Matthew Heon <mheon@redhat.com>
* apiv2 container create using specgenBrent Baude2020-02-19
this uses the specgen structure to create containers rather than the outdated createconfig. right now, only the apiv2 create is wired up. eventually the cli will also have to be done. Signed-off-by: Brent Baude <bbaude@redhat.com>
