* podman generate systemd --new do not duplicate paramsPaul Holzinger2021-03-28
| | | | | | | | | | | | | | | | | podman generate systemd --new inserts extra idfile arguments. The generated unit can break when the user did provide their own idfile arguments as they overwrite the arguments added by generate systemd. This also happens when a user tries to generate the systemd unit on a container already create with a --new unit. This should now create a identical unit. The solution is to remove all user provided idfile arguments. This commit also ensures that we do not remove arguments that are part off the containers entrypoint. Fixes #9776 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Add RequiresMountsFor= to systemd generateRobb Manes2021-03-26
| | | | | | | | | | | | | | | It is rare but possible that storage locations for the graphroot and the runroot are not mounted at boot time, and therefore might race when doing container operations. An example we've seen in the wild is that a slow tmpfs mount for the runroot would suddenly mount over /run, causing the container to lose all currently-running data, requiring a system refresh to get it back. This patch adds RequiresMountsFor= to the systemd.unit header to ensure the paths for both the graphroot and runroot are mounted prior to starting any generated unit files.

* Do not leak libpod package into the remote clientPaul Holzinger2021-03-15
| | | | | | | | | | | | | | | | | | Some packages used by the remote client imported the libpod package. This is not wanted because it adds unnecessary bloat to the client and also causes problems with platform specific code(linux only), see #9710. The solution is to move the used functions/variables into extra packages which do not import libpod. This change shrinks the remote client size more than 6MB compared to the current master. [NO TESTS NEEDED] I have no idea how to test this properly but with #9710 the cross compile should fail. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

* Fix broken podman generate systemd --new with podsPaul Holzinger2021-02-16
| | | | | | | | | | | The unit generation accidentally escaped the %t in the pod id file path. This is a regression caused by #9178. This was not caught by the tests because the test itself was wrong. It used a full path instead of the systemd variable %t like the actual code does.

* Fix podman generate systemd --new special char handlingPaul Holzinger2021-02-01
| | | | | | | | | | In a systemd unit dollar and percent signs are used for variables. A backslash is used for escape sequences. If any of these characters are used in the create command we have to properly escape them so systemd does not try to interpret them. Fixes #9176 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

* generate systemd: do not set `KillMode`Valentin Rothberg2021-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | `KillMode=none` has been deprecated in systemd and is now throwing big warnings when being used. Users have reported the issues upstream (see #8615) and on the mailing list. This deprecation was mainly motivated by an abusive use of third-party vendors causing all kinds of undesired side-effects. For instance, busy mounts that delay reboot. After talking to the systemd team, we came up with the following plan: **Short term**: we can use TimeoutStopSec and remove KillMode=none which will default to cgroup. **Long term**: we want to change the type to sdnotify. The plumbing for Podman is done but we need it for conmon. Once sdnotify is working, we can get rid of the pidfile handling etc. and let Podman handle it. Michal Seklatar came up with a nice idea that Podman increase the time out on demand. That's a much cleaner way than hard-coding the time out in the unit as suggest in the short-term solution. This change is executing the short-term plan and sets a minimum timeout of 60 seconds. User-specified timeouts are added to that. Fixes: #8615 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Add shell completion with cobraPaul Holzinger2020-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow automatic generation for shell completion scripts with the internal cobra functions (requires v1.0.0+). This should replace the handwritten completion scripts and even adds support for fish. With this approach it is less likley that completions and code are out of sync. We can now create the scripts with - podman completion bash - podman completion zsh - podman completion fish To test the completion run: source <(podman completion bash) The same works for podman-remote and podman --remote and it will complete your remote containers/images with the correct endpoints values from --url/--connection. The completion logic is written in go and provided by the cobra library. The completion functions lives in `cmd/podman/completion/completion.go`. The unit test at cmd/podman/shell_completion_test.go checks if each command and flag has an autocompletion function set. This prevents that commands and flags have no shell completion set. This commit does not replace the current autocompletion scripts. Closes #6440 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

* generate systemd: `ExecStopPost` for all unitsValentin Rothberg2020-06-17
| | | | | | | | | | | | | | | | Add an `ExecStopPost` run even for units generated without `--new`. Although it may seem redundant to run `container/pod stop` twice at first glance, we really need the post run. If the main PID (i.e., conmon) is killed, systemd will not execute `ExecStop` but only the post one. We made this obeservation in a customer issue and could reproduce the behavior consistently. Hence, the post run is needed to properly clean up when conmon is killed and it's pretty much a NOP in all other cases.

* 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.

* | generate systemd: add `default.target` to INSTALLValentin Rothberg2020-03-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | When enabling a systemd service we can specify which target will start it by specifying it in the `[INSTALL]` section. In case of root, this is commonly set to `multi-user.target` which is used to start other essential system services such as the network manager, D-BUS and more. However, the `multi-user.target` is not enough on all systems, especially when running rootless and enabling user services. Multiple users have reported issues that there isn't even an attempt to start the service. Setting the INSTALL target to `default.target` will fix the rootless case. However, `default.target` may vary among systems. Fedora Workstation, for instance, sets the `default.target` to the graphical target (i.e., runlevel 5) while Fedora Server sets it to `multi-user.target` which is on runlevel 2 and hence way earlier in the startup sequence. As INSTALL allows for specifying multiple INSTALL targets, we can set it to `multi-user.target` to continue supporting existing workloads AND to `default.target` which MAY redundantly attempt to start it at a later point; effectively a NOP for the root case and essential for rootless.
