* container inspect: improve error handlingValentin Rothberg2021-09-08
| | | | | | | | | | | | | Improve the error handling of `container inspect` to properly handle when the container has been removed _between_ the lookup and the inspect. That will yield the correct "no such object" error message in `inspect`. [NO TESTS NEEDED] since I do not know have a reliable and cheap reproducer. It's fixing a CI flake, so there's already an indicator. Fixes: #11392 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* podman stop always cleanupPaul Holzinger2021-09-01
| | | | | | | | | | | | | | | When a container is configured for auto removal podman stop should still do cleanup, there is no guarantee the the cleanup process spawned by conmon will be successful. Also a user expects after podman stop that the network/mounts are cleaned up. Therefore podman stop should not return early and instead do the cleanup and ignore errors if the container was already removed. [NO TESTS NEEDED] I don't know how to test this.

* InfraContainer Reworkcdoern2021-08-26
| | | | | | | | | | InfraContainer should go through the same creation process as regular containers. This change was from the cmd level down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state) Signed-off-by: cdoern <cdoern@redhat.com>
* Fix podman unpause,pause,kill --all to work like podman stop --allDaniel J Walsh2021-08-04
| | | | | | | | | | | | | | | | | | | Currently if you execute podman unpause --all, podman pause --all Podman shows attempts to unpause containers that are not paused and prints an error. This PR catches this error and only prints errors if a paused container was not able to be unpaused. Currently if you execute podman pause --all or podman kill --all, Podman Podman shows attempts to pause or kill containers that are not running and prints an error. This PR catches this error and only prints errors if a running container was not able to be paused or killed. Also change printing of multiple errors to go to stderr and to prefix "Error: " in front to match the output of the last error.

| * stats: add a interval parameter to cli and api stream modeThomas Weber2021-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | podman stats polled by default in a 1 sec period. This can put quite some load on a machine if you run many containers. The default value is now 5 seconds. You can change this interval with a new, optional, --interval, -i cli flag. The api request got also a interval query parameter for the same purpose. Additionally a unused const was removed. Api and cli will fail the request if a 0 or negative value is passed in. Signed-off-by: Thomas Weber <towe75@googlemail.com>
* | Support checkpoint/restore with podsAdrian Reber2021-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support to checkpoint containers out of pods and restore container into pods. It is only possible to restore a container into a pod if it has been checkpointed out of pod. It is also not possible to restore a non pod container into a pod. The main reason this does not work is the PID namespace. If a non pod container is being restored in a pod with a shared PID namespace, at least one process in the restored container uses PID 1 which is already in use by the infrastructure container. If someone tries to restore container from a pod with a shared PID namespace without a shared PID namespace it will also fail because the resulting PID namespace will not have a PID 1.

* | exec: fix cleanupValentin Rothberg2021-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 341e6a1 made sure that all exec sessions are getting cleaned up. But it also came with a peformance penalty. Fix that penalty by spawning the cleanup process to really only cleanup the exec session without attempting to remove the container. [NO TESTS NEEDED] since we have no means to test such performance issues in CI. Fixes: #10701 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* podman diff accept two images or containersPaul Holzinger2021-07-02
| | | | | | | | | | | | | | | | | | | First, make podman diff accept optionally a second argument. This allows the user to specify a second image/container to compare the first with. If it is not set the parent layer will be used as before. Second, podman container diff should only use containers and podman image diff should only use images. Previously, podman container diff would use the image when both an image and container with this name exists. To make this work two new parameters have been added to the api. If they are not used the previous behaviour is used. The same applies to the bindings. Fixes #10649 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

|/ | | | | | | | | | | | We were previously only doing this for detached exec.

* Add parameter to specify checkpoint archive compressionAdrian Reber2021-06-07
| | | | | | | | | | | | | | | The checkpoint archive compression was hardcoded to `archive.Gzip`. There have been requests to make the used compression algorithm selectable. There was especially the request to not compress the checkpoint archive to be able to create faster checkpoints when not compressing it. This also changes the default from `gzip` to `zstd`. This change should not break anything as the restore code path automatically handles whatever compression the user provides during restore. Signed-off-by: Adrian Reber <areber@redhat.com>
* Drop container does not exist on removal to debugfDaniel J Walsh2021-05-21
| | | | | | | | | | | | | | | | We have race conditions where a container can be removed by two different processes when running podman --remove rm. It can be cleaned up in the API or by the conmon executing podman container cleanup. When we fail to remove a container that does not exists we should not be printing errors or warnings, we should just debug the fact. [NO TESTS NEEDED] Since this is a race condition it is difficult to test. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate the Podman code base over to `common/libimage` which replaces `libpod/image` and a lot of glue code entirely. Note that I tried to leave bread crumbs for changed tests. Miscellaneous changes: * Some errors yield different messages which required to alter some tests. * I fixed some pre-existing issues in the code. Others were marked as `//TODO`s to prevent the PR from exploding. * The `NamesHistory` of an image is returned as is from the storage. Previously, we did some filtering which I think is undesirable. Instead we should return the data as stored in the storage. * Touched handlers use the ABI interfaces where possible. * Local image resolution: previously Podman would match "foo" on "myfoo". This behaviour has been changed and Podman will now only match on repository boundaries such that "foo" would match "my/foo" but not "myfoo". I consider the old behaviour to be a bug, at the very least an exotic corner case. * Futhermore, "foo:none" does *not* resolve to a local image "foo" without tag anymore. It's a hill I am (almost) willing to die on. * `image prune` prints the IDs of pruned images. Previously, in some cases, the names were printed instead. The API clearly states ID, so we should stick to it. * Compat endpoint image removal with _force_ deletes the entire not only the specified tag. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman has, for a long time, had an internal concept of dependency management, used mainly to ensure that pod infra containers are started before any other container in the pod. We also have the ability to recursively start these dependencies, which we use to ensure that `podman start` on a container in a pod will not fail because the infra container is stopped. We have not, however, exposed these via the command line until now. Add a `--requires` flag to `podman run` and `podman create` to allow users to manually specify dependency containers. These containers must be running before the container will start. Also, make recursive starting with `podman start` default so we can start these containers and their dependencies easily.

| | | | | | | | | | | | Since commit d54478d8eaec, a container's lock is released before attempting to stop it via the OCI runtime. This opened the window for various kinds of race conditions.

* Initial implementation of renaming containersMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic theory: We remove the container, but *only from the DB*. We leave it in c/storage, we leave the lock allocated, we leave it running (if it is). Then we create an identical container with an altered name, and add that back to the database. Theoretically we now have a renamed container. The advantage of this approach is that it doesn't just apply to rename - we can use this to make *any* configuration change to a container that does not alter its container ID. Potential problems are numerous. This process is *THOROUGHLY* non-atomic at present - if you `kill -9` Podman mid-rename things will be in a bad place, for example. Also, we can't rename containers that can't be removed normally - IE, containers with dependencies (pod infra containers, for example). The largest potential improvement will be to move the majority of the work into the DB, with a `RecreateContainer()` method - that will add atomicity, and let us remove the container without worrying about depencies and similar issues. Potential problems: long-running processes that edit the DB and may have an older version of the configuration around. Most notable example is `podman run --rm` - the removal command needed to be manually edited to avoid this one. This begins to get at the heart of me not wanting to do this in the first place... This provides CLI and API implementations for frontend, but no tunnel implementation. It will be added in a future release (just held back for time now - we need this in 3.0 and are running low on time). This is honestly kind of horrifying, but I think it will work.

* Include named volumes in container migrationRadostin Stoyanov2021-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When migrating a container with associated volumes, the content of these volumes should be made available on the destination machine. This patch enables container checkpoint/restore with named volumes by including the content of volumes in checkpoint file. On restore, volumes associated with container are created and their content is restored. The --ignore-volumes option is introduced to disable this feature. Example: # podman container checkpoint --export checkpoint.tar.gz <container> The content of all volumes associated with the container are included in `checkpoint.tar.gz` # podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container> The content of volumes is not included in `checkpoint.tar.gz`. This is useful, for example, when the checkpoint/restore is performed on the same machine. # podman container restore --import checkpoint.tar.gz The associated volumes will be created and their content will be restored. Podman will exit with an error if volumes with the same name already exist on the system or the content of volumes is not included in checkpoint.tar.gz # podman container restore --ignore-volumes --import checkpoint.tar.gz Volumes associated with container must already exist. Podman will not create them or restore their content. Signed-off-by: Radostin Stoyanov <rstoyanov@fedoraproject.org>

* Add support for external containerDaniel J Walsh2020-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | External containers are containers created outside of Podman. For example Buildah and CRI-O Containers. $ buildah from alpine alpine-working-container $ buildah run alpine-working-container touch /test $ podman container exists --external alpine-working-container $ podman container diff alpine-working-container C /etc A /test Added --external flag to refer to external containers, rather then --storage. Added --external for podman container exists and modified podman ps to use --external rather then --storage. It was felt that --storage would confuse the user into thinking about changing the storage driver or options. --storage is still supported through the use of aliases. Finally podman contianer diff, does not require the --external flag, since it there is little change of users making the mistake, and would just be a pain for the user to remember the flag. podman container exists --external is required because it could fool scripts that rely on the existance of a Podman container, and there is a potential for a partial deletion of a container, which could mess up existing users.
