|\ | | | | | | | | jakecorrenti/restart-privelaged-containers-after-host-device-change Privileged containers can now restart if the host devices change
| * Privileged containers can now restart if the host devices changeJake Correnti2022-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a privileged container is running, stops, and the devices on the host change, such as a USB device is unplugged, then a container would no longer start. Previously, the devices from the host were only being added to the container once: when the container was created. Now, this happens every time the container starts. I did this by adding a boolean to the container config that indicates whether to mount all of the devices or not, which can be set via an option. During spec generation, if the `MountAllDevices` option is set in the container config, all host devices are added to the container. Additionally, a couple of functions from `pkg/specgen/generate/config_linux.go` were moved into `pkg/util/utils_linux.go` as they were needed in multiple packages.

* | overlay-volumes: add support for non-volatile upperdir,workdir for anonymous ↵Aditya R2022-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | volumes Similar feature was added for named overlay volumes here: https://github.com/containers/podman/pull/12712 Following PR just mimics similar feature for anonymous volumes. Often users want their anonymous overlayed volumes to be `non-volatile` in nature that means that same `upper` dir can be re-used by one or more containers but overall of nature of volumes still have to be overlay so work done is still on a overlay not on the actual volume. Following PR adds support for more advanced options i.e custom `workdir` and `upperdir` for overlayed volumes. So that users can re-use `workdir` and `upperdir` across new containers as well. Usage ```console podman run -it -v /some/path:/data:O,upperdir=/path/persistant/upper,workdir=/path/persistant/work alpine sh ``` Signed-off-by: Aditya R <arajan@redhat.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When podman-remote is used we should not resolve the default network mode on the client. Defaults should be set on the server. In this case this is important because we have different defaults for root/rootless. So when the client is rootless and the server is root we must pick the root default. Note that this already worked when --network was set since we did not parsed the flag in this case. To reproduce you need --network=default. Also removed a unused function. [NO NEW TESTS NEEDED] I tested it manually but I am not sure how I can hook a test like this up in CI. The client would need to run as rootless and the server as root or the other way around. Fixes #14368 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* [BZ #2083997] pod: build pause image in custom user NSValentin Rothberg2022-05-13
| | | | | | | | | | | Use the host UID and host GID mapping when building the local pause image for a Pod with a custom mapping. Otherwise, the mappings are off and the build fails. Propagating the mapping to the build container is not needed since the pause image ships merely a copied `catatonit` from the host.

* play kube: service containerValentin Rothberg2022-05-12
| | | | | | | | | | | | | | | | | | | | Add the notion of a "service container" to play kube. A service container is started before the pods in play kube and is (reverse) linked to them. The service container is stopped/removed *after* all pods it is associated with are stopped/removed. In other words, a service container tracks the entire life cycle of a service started via `podman play kube`. This is required to enable `play kube` in a systemd unit file. The service container is only used when the `--service-container` flag is set on the CLI. This flag has been marked as hidden as it is not meant to be used outside the context of `play kube`. It is further not supported on the remote client. The wiring with systemd will be done in a later commit. Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The directory created by `t.TempDir` is automatically removed when the test and all its subtests complete. Prior to this commit, temporary directory created using `ioutil.TempDir` needs to be removed manually by calling `os.RemoveAll`, which is omitted in some tests. The error handling boilerplate e.g. defer func() { if err := os.RemoveAll(dir); err != nil { t.Fatal(err) } } is also tedious, but `t.TempDir` handles this for us nicely.

* / 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".

* 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>
