* Add DefaultContent API to retrieve apparmor profile contentSascha Grunert2019-07-18
| | | | | | | | The default apparmor profile is not stored on disk which causes confusion when debugging the content of the profile. To solve this, we now add an additional API which returns the profile as byte slice. Signed-off-by: Sascha Grunert <sgrunert@suse.com>

| * Move the HostConfig portion of Inspect inside libpodMatthew Heon2019-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we first began writing Podman, we ran into a major issue when implementing Inspect. Libpod deliberately does not tie its internal data structures to Docker, and stores most information about containers encoded within the OCI spec. However, Podman must present a CLI compatible with Docker, which means it must expose all the information in 'docker inspect' - most of which is not contained in the OCI spec or libpod's Config struct. Our solution at the time was the create artifact. We JSON'd the complete CreateConfig (a parsed form of the CLI arguments to 'podman run') and stored it with the container, restoring it when we needed to run commands that required the extra info. Over the past month, I've been looking more at Inspect, and refactored large portions of it into Libpod - generating them from what we know about the OCI config and libpod's (now much expanded, versus previously) container configuration. This path comes close to completing the process, moving the last part of inspect into libpod and removing the need for the create artifact. This improves libpod's compatability with non-Podman containers. We no longer require an arbitrarily-formatted JSON blob to be present to run inspect.

| | | | | | | | | | | | | | | | It is not correct to rely on specific location of the podman binary. In most cases it is /usr/bin/podman, but sometimes is not (e.g. in system tests). Use /proc/self/exe instead of hardcoded path. Signed-off-by: Danila Kiver <danila.kiver@mail.ru>
| * Use conmon pidfile in generated systemd unit as PIDFile.Danila Kiver2019-07-04
| | | | | | | | | | | | | | | | | | | | | | By default, podman points PIDFile in generated unit file to non-existent location. As a result, the unit file, generated by podman, is broken: an attempt to start this unit without prior modification results in a crash, because systemd can not find the pidfile of service's main process.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an initial implementation of cgroup v2 support for pkg/cgroups. It currently works with crun, with this patch: https://github.com/giuseppe/crun/pull/49). It adds the pieces for: - set PID limit to 1 - retrieve stats so that "podman stats" work. the only missing part is the support for reading per CPU stats (that is cpuacct.usage_percpu on cgroup v1), so for now it always returns an empty result.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | provide a package for managing cgroups. This is not supposed to be a complete implementation with all the features supported by cgroups, but it is a minimal implementation designed around what libpod needs and it is currently using. For example, it is currently possible to Apply only the pids limit, as it is used by libpod for stopping containers, any other Apply will just fail. The main goal here is to have a minimal library where we have full control, so we can start playing with cgroup v2. When the need arises, we can add more features.
