* 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>

* generate systemd: catch `--name=foo`Valentin Rothberg2020-09-09
| | | | | | | | | | | The systemd generator looks for certain flags in the containers' create commands to determine which flags need to be added. In case of named containers, the generator adds the `--replace` flag to prevent name conflicts at container creation. Fix the generator to not only cover the `--name foo` syntax but also the `--name=foo` one. Fixes: #7157 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* APIv2 add generate systemd endpointPaul Holzinger2020-09-02
| | | | | | | | | | | | | Add support for generating systemd units via the api and podman-remote. Change the GenerateSystemdReport type to return the units as map[string]string with the unit name as key. Add `--format` flag to `podman generate systemd` to allow the output to be formatted as json.

* generate systemd: quote arguments with whitespaceValentin Rothberg2020-08-19
| | | | | | | | | | | Make sure that arguments with whitespace are properly quoted so they are interpreted as one (and not multiple ones) by systemd. Now `-e tz="america/new york"` will be generated as `-e "tz=america/new york"`. The quotes are moving but the argument is still correct.

* 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].

* systemd generate: allow manual restart of container units in podsValentin Rothberg2020-06-25
| | | | | | | | Allow manual restarts of container units that are part of a pod. This allows for configuring these containers for auto updates. Fixes: #6770 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* 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. Credits to Ulrich Obergfell for throrough and detailed analyses, which ultimately lead to this fix. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* generate systemd: `--replace` on named containers/podsValentin Rothberg2020-06-15
| | | | | | | | | Use `--replace` for named containers and pods. This will clean up previous containers and podsthat may not have been removed after a system crash. Fixes: #5485 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* generate systemd: create pod templateValentin Rothberg2020-06-11
| | | | | | | | | | Create a new template for generating a pod unit file. Eventually, this allows for treating and extending pod and container generation seprately. The `--new` flag now also works on pods. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* generate systemd: refactorValentin Rothberg2020-06-11
| | | | | | | | | | | | Refactor the systemd-unit generation code and move all the logic into `pkg/systemd/generate`. The code was already hard to maintain but I found it impossible to wire the `--new` logic for pods in all the chaos. The code refactoring in this commit will make maintaining the code easier and should make it easier to extend as well. Further changes and refactorings may still be needed but they will easier.
