* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* auto-update: use image's archValentin Rothberg2020-06-16
| | | | | | | | | Use the architecture of the local image when looking for a new image on a registry. It seems to be common practice on ARM to tweak the architecture choice to pull the correct image. Fixes: #6613 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* auto-update: support authfilesValentin Rothberg2020-05-12
| | | | | | | | | | Support using custom authfiles for auto updates by adding a new `--authfile` flag and passing it down into the backend. Also do some minor fixes in the help text and the man page. Fixes: #6159 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* auto update: skip non-image policiesValentin Rothberg2020-04-14
| | | | | | | Fix a bug in the auto-update logic causing all images to be checked and not only the ones of containers with the specific auto-update policy. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* 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.
