* auto-update: simple rollbackValentin Rothberg2021-08-05
| | | | | | | | | | | | | | | | | | | Add support for simple rollbacks during `podman auto-update`. Rollbacks are enabled by default. If a systemd unit cannot be restarted after an update, the previous image will be retagged and the unit will be restarted a second time. Add system tests for rollbacks. Also fix a bug in the restart sequence; we have to use the channel to actually know whether the restart was successful or not. NOTE: To make rollbacks really useful, users must run their containers with `--sdnotify=container` such that the containers send the ready message over the (mounted) socket. This way, restarting the systemd units during auto update will block until the message has been received (or a timeout kicked in). Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* auto-update: add --dry-runValentin Rothberg2021-07-15
| | | | | | | | | | | | | | | | | Add a --dry-run flag to `podman auto-update` which will look for new images but won't perform any pull or restart any service or container. The "UPDATED" column will now indicate the availability of a newer image via "pending". ``` $ podman auto-update --dry-run UNIT CONTAINER IMAGE POLICY UPDATED container-test.service 08fd34e533fd (test) localhost:5000/busybox registry false ``` Fixes: #9949 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* auto-update: make output more user friendlyValentin Rothberg2021-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rather raw and scarce output of `podman auto-update` has been a thorn in my eyes for a longer while. So far, Podman would only print updated systemd units, one per line, without further formatting. Motivated by issue #9949 which is asking for some more useful information in combination with a dry-run feature, I sat down and reflected which information may come in handy. Running `podman auto-update` will now look as follows: ``` $ podman auto-update Trying to pull [...] UNIT CONTAINER IMAGE POLICY UPDATED container-test.service 08fd34e533fd (test) localhost:5000/busybox registry false ``` Also refactor the spaghetti code in the backend a bit to make it easier to digest and maintain. For easier testing and for the sake of consistency with other commands listing output, add a `--format` flag. The man page will get an overhaul in a follow up commit.

* 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-updateValentin Rothberg2020-05-08
Add the `podman auto-update` command. There have been no tests in v1, so there are no in v2 either ... for now :) Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
