* podman container clone env patchCharlie Doern2022-09-16
| | | | | | | | | podman container clone was failing when env variables had multiple `=` in them. Switch split to splitn resolves #15836 Signed-off-by: Charlie Doern <cdoern@redhat.com>
* Fix stuttersDaniel J Walsh2022-09-10
| | | | | | | | | | | | | | Podman adds an Error: to every error message. So starting an error message with "error" ends up being reported to the user as Error: error ... This patch removes the stutter. Also ioutil.ReadFile errors report the Path, so wrapping the err message with the path causes a stutter. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* specgen/generate: Factor out setting resource limits from CompleteSpecDoug Rabson2022-09-08

* implement podman updateCharlie Doern2022-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | podman update allows users to change the cgroup configuration of an existing container using the already defined resource limits flags from podman create/run. The supported flags in crun are: this command is also now supported in the libpod api via the /libpod/containers/<CID>/update endpoint where the resource limits are passed inthe request body and follow the OCI resource spec format –memory –cpus –cpuset-cpus –cpuset-mems –memory-swap –memory-reservation –cpu-shares –cpu-quota –cpu-period –blkio-weight –cpu-rt-period –cpu-rt-runtime -device-read-bps -device-write-bps -device-read-iops -device-write-iops -memory-swappiness -blkio-weight-device resolves #15067 Signed-off-by: Charlie Doern <cdoern@redhat.com>

* specgen,run: support running container from valid manifest listAditya R2022-07-05
| | | | | | | | | | | | | | | | | | | | | Following PR adds support for running containers from a manifest list present on localstorage. Before this PR podman only supports running containers from valid images but not from manifest list. So `podman run -it --platform <some> <manifest-list> command` should become functional now and users should be able to resolve images on the bases of provided `--platform` string. Example ``` podman manifest create test podman build --platform linux/amd64,linux/arm64 --manifest test . podman run --rm --platform linux/arm64/v8 test uname -a ``` Closes: https://github.com/containers/podman/issues/14773 Signed-off-by: Aditya R <arajan@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.

* fix healthcheck timeouts and ut8 coercionBrent Baude2022-01-06
| | | | | | | | | | | | | | | | | this commit fixes two bugs and adds regression tests. when getting healthcheck values from an image, if the image does not have a timeout defined, this resulted in a 0 value for timeout. The default as described in the man pages is 30s. when inspecting a container with a healthcheck command, a customer observed that the &, <, and > characters were being converted into a unicode escape value. It turns out json marshalling will by default coerce string values to ut8. Fixes: bz2028408 Signed-off-by: Brent Baude <bbaude@redhat.com>
* container creation: don't apply reserved annotations from imageValentin Rothberg2021-12-23
| | | | | | | | | | Do not apply reserved annotations from the image to the container.

* Add --unsetenv & --unsetenv-all to remove def environment variablesDaniel J Walsh2021-11-15
| | | | | | | | | | | | | | | | Podman adds a few environment variables by default, and currently there is no way to get rid of them from your container. This option will allow you to specify which defaults you don't want. --unsetenv-all will remove all default environment variables. Default environment variables can come from podman builtin, containers.conf or from the container image.

* faster image inspectionValentin Rothberg2021-10-08
| | | | | | | | | | | | | | Vendor the latest HEAD in c/common to pull in changes for a faster inspection of images. Previously, only the size computation was optional, now the one for the parent image is as well. In many cases, the parent image is not needed but it takes around 10ms on my local machine. With this change, we cut off 10ms from many code paths, most importantly, container creation. [NO NEW TESTS NEEDED] Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* implement init containers in podmanBrent Baude2021-08-04
| | | | | | | | | | | | | | this is the first pass at implementing init containers for podman pods. init containersare made popular by k8s as a way to run setup for pods before the pods standard containers run. unlike k8s, we support two styles of init containers: always and oneshot. always means the container stays in the pod and starts whenever a pod is started. this does not apply to pods restarting. oneshot means the container runs onetime when the pod starts and then is removed.

* | create: support images with invalid platformValentin Rothberg2021-06-23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Much to my regret, there is a number of images in the wild with invalid platforms breaking the platform checks in libimage that want to make sure that a local image is matching the expected platform. Imagine a `podman run --arch=arm64 fedora` with a local amd64 fedora image. We really shouldn't use the local one in this case and pull down the arm64 one. The strict platform checks in libimage in combination with invalid platforms in images surfaced in Podman being able to pull an image but failing to look it up in subsequent presence checks. A `podman run` would hence pull such an image but fail to create the container. Support images with invalid platforms by vendoring the latest HEAD from containers/common. Also remove the partially implemented pull-policy logic from Podman and let libimage handle that entirely. However, whenever --arch, --os or --platform are specified, the pull policy will be forced to "newer". This way, we pessimistically assume that the local image has an invalid platform and we reach out to the registry. If there's a newer image (i.e., one with a different digest), we'll pull it down. Please note that most of the logic has either already been implemented in libimage or been moved down which allows for removing some clutter from Podman. [NO TESTS NEEDED] since c/common has new tests. Podman can rely on the existing tests. Fixes: #10648 Fixes: #10682 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* migrate Podman to containers/common/libimageValentin Rothberg2021-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
