| | | | | | | | | | | | | | | In support of podman machine and its counterpart desktop, we have added new stats to podman info. For storage, we have added GraphRootAllocated and GraphRootUsed in bytes. For CPUs, we have added user, system, and idle percents based on /proc/stat.

|\ | | | | pod: add exit policies
| * pod: add exit policiesValentin Rothberg2022-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the notion of an "exit policy" to a pod. This policy controls the behaviour when the last container of pod exits. Initially, there are two policies: - "continue" : the pod continues running. This is the default policy when creating a pod. - "stop" : stop the pod when the last container exits. This is the default behaviour for `play kube`. In order to implement the deferred stop of a pod, add a worker queue to the libpod runtime. The queue will pick up work items and in this case helps resolve dead locks that would otherwise occur if we attempted to stop a pod during container cleanup. Note that the default restart policy of `play kube` is "Always". Hence, in order to really solve #13464, the YAML files must set a custom restart policy; the tests use "OnFailure".

* | libpod: unset networks before storing container confPaul Holzinger2022-05-02
|/ | | | | | | | | | | | Since networks must always be read from the db bucket directly we should unset them in config to avoid caller from accidentally using them. I already tried this but it didn't work because the networks were unset after the config was marshalled. [NO NEW TESTS NEEDED] Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| * libpod: host netns keep same /etc/resolv.confPaul Holzinger2022-04-29
| | | | | | | | | | | | | | | | | | | | | | | | When a container is run in the host network namespace we have to keep the same resolv.conf content and not use the systemd-resolve detection logic. But also make sure we still allow --dns options. Fixes #14055 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
| * fix incorrect permissions for /etc/resolv.conf in usernsPaul Holzinger2022-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The files /etc/hosts, /etc/hostname and /etc/resolv.conf should always be owned by the root user in the container. This worked correct for /etc/hostname and /etc/hosts but not for /etc/resolv.conf. A container run with --userns keep-id would have the reolv.conf file owned by the current container user which is wrong. Consolidate some common code in a new helper function to make the code more cleaner. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* / libpod: unlock containers when removing podGiuseppe Scrivano2022-04-29
|/ | | | | | | | | | | | | | | | | It solves a race where a container cleanup process launched because of the container process exiting normally would hang. It also solves a problem when running as rootless on cgroup v1 since it is not possible to force pids.max = 1 on conmon to limit spawning the cleanup process.

* | volume: add new option -o o=noquotaGiuseppe Scrivano2022-04-28
|/ | | | | | | | | | | | | | | | | add a new option to completely disable xfs quota usage for a volume. xfs quota set on a volume, even just for tracking disk usage, can cause weird errors if the volume is later re-used by a container with a different quota projid. More specifically, link(2) and rename(2) might fail with EXDEV if the source file has a projid that is different from the parent directory. To prevent such kind of issues, the volume should be created beforehand with `podman volume create -o o=noquota $ID` Closes: https://github.com/containers/podman/issues/14049 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* | enable gocritic linterPaul Holzinger2022-04-26
|/ | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style. This should help maintainability. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an enhancement proposal for the checkpoint / restore feature of Podman that enables container migration across multiple systems with standard image distribution infrastructure. A new option `--create-image <image>` has been added to the `podman container checkpoint` command. This option tells Podman to create a container image. This is a standard image with a single layer, tar archive, that that contains all checkpoint files. This is similar to the current approach with checkpoint `--export`/`--import`. This image can be pushed to a container registry and pulled on a different system. It can also be exported locally with `podman image save` and inspected with `podman inspect`. Inspecting the image would display additional information about the host and the versions of Podman, criu, crun/runc, kernel, etc. `podman container restore` has also been extended to support image name or ID as input.
