* Fix `system service` panic from early hangup in eventsMatthew Heon2020-07-02
| | | | | | | | | | | | We weren't actually halting the goroutine that sent events, so it would continue sending even when the channel closed (the most notable cause being early hangup - e.g. Control-c on a curl session). Use a context to cancel the events goroutine and stop sending events. Fixes #6805 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* 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.

* Expose Null eventer and allow its use in the Podman CLIMatthew Heon2019-07-31
| | | | | | | | We need this specifically for tests, but others may find it useful if they don't explicitly need events and don't want the performance implications of using them. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* journald event loggingbaude2019-04-24
add the ability for podman to read and write events to journald instead of just a logfile. This can be controlled in libpod.conf with the `events_logger` attribute of `journald` or `file`. The default will be set to `journald`. Signed-off-by: baude <bbaude@redhat.com>
