* stats: cap memory limit to the available memoryGiuseppe Scrivano2022-09-15
| | | | | | | | | Docker compatibility: cap the memory limit reported by the cgroup to the maximum available memory. Closes: https://github.com/containers/podman/issues/15765 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* stats: map MaxUsage to the correct valueGiuseppe Scrivano2022-09-15

* pkg: switch to golang native error wrappingSascha Grunert2022-07-08
| | | | | | | | | We now use the golang error wrapping format specifier `%w` instead of the deprecated github.com/pkg/errors package. [NO NEW TESTS NEEDED] Signed-off-by: Sascha Grunert <sgrunert@redhat.com>
* podman cgroup enhancementcdoern2022-06-24
| | | | | | | | | | | currently, setting any sort of resource limit in a pod does nothing. With the newly refactored creation process in c/common, podman ca now set resources at a pod level meaning that resource related flags can now be exposed to podman pod create. cgroupfs and systemd are both supported with varying completion. cgroupfs is a much simpler process and one that is virtually complete for all resource types, the flags now just need to be added. systemd on the other hand has to be handeled via the dbus api meaning that the limits need to be passed as recognized properties to systemd. The properties added so far are the ones that podman pod create supports as well as `cpuset-mems` as this will be the next flag I work on. Signed-off-by: Charlie Doern <cdoern@redhat.com>
* Fix spelling "setup" -> "set up" and similarErik Sjölund2022-06-22
| | | | | | | | | | * Replace "setup", "lookup", "cleanup", "backup" with "set up", "look up", "clean up", "back up" when used as verbs. Replace also variations of those. * Improve language in a few places. Signed-off-by: Erik Sjölund <erik.sjolund@gmail.com>
* api: show the memory limit specified for the containerGiuseppe Scrivano2022-06-21
| | | | | | | | | | | use the memory limit specified for the container instead of reading it from the cgroup. It is not reliable to read it from the cgroup since the container could have been moved to a different cgroup and in general the OCI runtime might create a sub-cgroup (like crun does).

* Non-running containers now report statistics via the `podman stats`Jake Correnti2022-06-13
| | | | | | | | | | | | | | | | | | | | | | command Previously, if a container was not running, and the user ran the `podman stats` command, an error would be reported: `Error: container state improper`. Podman now reports stats as the fields' default values for their respective type if the container is not running: ``` $ podman stats --no-stream demo ID NAME CPU % MEM USAGE / LIMIT MEM % NET IO BLOCK IO PIDS CPU TIME AVG CPU % 4b4bf8ce84ed demo 0.00% 0B / 0B 0.00% 0B / 0B 0B / 0B 0 0s 0.00% ``` Closes: #14498 Signed-off-by: Jake Correnti <jcorrenti13@gmail.com>
* podman stats: calc CPU percentage correctlyPaul Holzinger2022-03-22
| | | | | | | | | | | | | | | | | | | | | When you run podman stats, the first interval always shows the wrong cpu usage. To calculate cpu percentage we get the cpu time from the cgroup and compare this against the system time between two stats. Since the first time we do not have a previous stats an empty struct is used instead. Thus we do not use the actual running time of the container but the current unix timestamp (time since Jan 1 1970). To fix this we make sure that the previous stats time is set to the container start time, when it is empty. [NO NEW TESTS NEEDED] No idea how I could create a test which would have a predictable cpu usage. See the linked bugzilla for a reproducer.

* 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].
