* Added option to share kernel namespaces in libpod and podmanhaircommander2018-08-23
| | | | | | | | | A pause container is added to the pod if the user opts in. The default pause image and command can be overridden. Pause containers are ignored in ps unless the -a option is present. Pod inspect and pod ps show shared namespaces and pause container. A pause container can't be removed with podman rm, and a pod can be removed if it only has a pause container.

* Changed GetContainerStats to return ErrCtrStateInvalidhaircommander2018-08-23
| | | | | | | | | | | | | | This results in some functionality changes: If a ErrCtrStateInvalid is returned to GetPodStats, the container is ommitted from the stats. As such, if an empty slice of Container stats are returned to GetPodStats in varlink, an error will occur. GetContainerStats will return the ErrCtrStateInvalid as well. Finally, if ErrCtrStateInvalid is returned to the podman stats call, the container will be ommitted from the stats. Signed-off-by: haircommander <pehunt@redhat.com> Closes: #1319 Approved by: baude
* Add podman pod tophaircommander2018-08-23
| | | | | | | | | Using the vendored changes from psgo, incorporate JoinNamespaceAndProcessInfoByPids to get process information for each pid namespace of running containers in the pod. Also added a man page, and tests. Signed-off-by: haircommander <pehunt@redhat.com> Closes: #1298 Approved by: mheon
* Properly translate users into runc format for execMatthew Heon2018-08-23
| | | | | | | | | | | Runc exec expects the --user flag to be formatted as UID:GID. Use chrootuser code to translate whatever user is passed to exec into this format. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1315 Approved by: vrothberg

* Make failure to retrieve individual ctrs/pods nonfatalMatthew Heon2018-08-17
| | | | | | | | | | | | This ensures that we can still use Podman even if a container or pod with bad config JSON makes it into the state. We still can't remove these containers, but at least we can do our best to make things usable. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1294 Approved by: rhatdan
* podman: fix --uts=hostGiuseppe Scrivano2018-08-17
| | | | | | | | | | | | | | | Do not set any hostname value in the OCI configuration when --uts=host is used and the user didn't specify any value. This prevents an error from the OCI runtime as it cannot set the hostname without a new UTS namespace. Differently, the HOSTNAME environment variable is always set. When --uts=host is used, HOSTNAME gets the value from the host. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com> Closes: #1280 Approved by: baude

* | We need to sort mounts so that one mount does not over mount another.Daniel J Walsh2018-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we add mounts from images, volumes and internal. We can accidently over mount an existing mount. This patch sorts the mounts to make sure a parent directory is always mounted before its content. Had to change the default propagation on image volume mounts from shared to private to stop mount points from leaking out of the container. Also switched from using some docker/docker/pkg to container/storage/pkg to remove some dependencies on Docker. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #1243 Approved by: mheon
* | Split pod.go into 3 filesMatthew Heon2018-08-10
| | | | | | | | | | | | | | | | | | | | | | This removes anything but structs and simple accessors from pod.go itself, which is a target file for FFJSON generation. This should reduce the amount of times FFJSON needs to run. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1247 Approved by: rhatdan
* | Make errors during refresh nonfatalMatthew Heon2018-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During refresh, we cannot hard-fail, as that would mean leaving a partially-configured state behind, leaving libpod unable to start without manual intervention. Instead, log errors refreshing individual containers and pods and continue. Individual containers and pods may be unusable and need to be removed manually, but libpod itself will continue to function.

* Better pull error for fully-qualified imagesbaude2018-08-06
| | | | | | | | | | | | | | | | | | | When pulling a fully-qualified image that fails, we should not be talking about registries/search registries in the the error message as it is not applicable. If a image that is fq'd and fails to pull, the error should be simplified. ``` $ sudo podman pull this-does-not-exist.example.com/foo Trying to pull this-does-not-exist.example.com/foo...Failed error pulling image "this-does-not-exist.example.com/foo": unable to pull this-does-not-exist.example.com/foo: unable to pull image, or you do not have pull access $ ``` Resolves: #1212 Signed-off-by: baude <bbaude@redhat.com> Closes: #1216 Approved by: mheon

| | | | | | | | | | | | | when pulling, we can fail to find an image (i.e. it doesn't exist) or we can not have authority/access to pull it. the registries don't tell us one way or another so the error message needs to cover both.

| | | | | | | | | | | | | | | Runtime.pullGoalFromPossibly... Again, we only needed them split for tests; so, integrate them back.

* Replace getPullRefName by Runtime.getPullRefPairMiloslav Trmač2018-08-02
| | | | | | | | | | | | | | | | | | This more or less reverts 9c9401a96c0b7d43dcea19c2972ef9612cc0a136 "Replace getPullRefPair with getPullRefName"; now that tests don't require us to use pullRefName, move creation of storage references deeper into the calls stack to reduce string use. ir.getSinglePullRefNameGoal is accordingly updated to ir.getSinglePullRefPairGoal, and we need to add a ~duplicate singlePullRefPairGoal; that duplication of singlePullRefNameGoal will soon be resolved by dropping singlePullRefNameGoal. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* Inline pullGoalNamesFromImageReference back into ↵Miloslav Trmač2018-08-02
| | | | | | | | | | | | | | | | | | Runtime.pullGoalFromImageReference Now that we don't need a separate pullGoalNamesFromImageReference for running tests, inline it back. This forces us to add some glue code to getSinglePullRefNameGoal and to convert between pullGoal and *pullGoal; that is temporary and will be cleaned up soon. Should not change behavior.

* Introduce getSinglePullRefNameGoalMiloslav Trmač2018-08-02
| | | | | | | | | | | | | | | | | This merely wraps the > return singlePullRefNameGoal(getPullRefName(... reference)), nil pattern which is used for almost all getPullRefName uses. For now it seems not really worth it, but it will result in shorter code (and smaller migration) after we replace getPullRefName with getPullRefPair, which can fail, again - the pullGoalNamesFromImageReference will not have to add any error handling. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* Test Runtime.pullGoalFromPossiblyUnqualifiedName instead of pullGoalNameFrom...Miloslav Trmač2018-08-02
| | | | | | | | | | | | | | Similarly to pullGoalNamesFromImageReference, use a storage.Store and test the actually created references; that is more representative, and clearly shows the impact of further normalization in storageReference (like defaulting to :latest on NameOnly references). Only modifies tests, so does not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* Test Runtime.pullGoalFromImageReference instead of ↵Miloslav Trmač2018-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | pullGoalNamesFromImageReference pullGoalNamesFromImageReference has been added only to allow testing without a storage.Store, because I thought that a storage.Store can only be created by root. It turns out that non-root stores, at least good enough for reference parsing and formatting, are possible (and have existed in c/image/storage tests), so this creates such a store, and modifies the existing test to test the created c/image/storage.storageReference values instead of strings; that is more representative, and clearly shows the impact of further normalization in storageReference (like defaulting to :latest on NameOnly references). Eventually we will want to get rid of pullGoalNames / pullRefName. Only modifies tests, so does not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* RFC: Rename runtime.pullImage to runtime.pullImageFromHeuristicSourceMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | This is similar to the PushImageToHeuristicDestination RFC. The goal is to be very explicit about which functions try to heuristically guess what is the expected format of the string. Not quite "shaming" the users, but making sure they stand out. RFC: - Is this at all acceptable? Desirable? Should not change behavior (but does not add unit tests). Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Introduce Runtime.pullImageFromReference, call it in Runtime.FromImageReferenceMiloslav Trmač2018-08-01
| | | | | | | | | | | FINALLY, (podman load) can pass through an ImageReference directly from loadCmd all the way to pullGoalNamesFromImageReference, making sure not to trigger the docker-like reference parsing heuristics. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* RFC: Remove unused transport name constants from libpodMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | | They are not used anywhere in the packagee. Two of the values still have users in the CLI, but used only once. So, use the .Transport.Name() calls in there directly, that is likely to be cheaper (and makes the files depend directly on the transports instead of referring to them indirectly through libpod). RFC: Should not change behavior in _this_ repo, but it is an externally-observable API change. Is there any user that could notice? Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Replace Runtime.LoadFromArchive with Runtime.LoadFromArchiveReferenceMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | All callers of LoadFromArchive expect the input to be in the transport:name format, or create it that way. So, pass a types.ImageReference instead of a string. That requires us to add an explicit parse step in (podman pull); in (podman load) we can, instead of pasting strings, create native objects directly. Changes the error behavior of (podman pull), we no longer try heuristically parsing docker-archive:... inputs as Docker references. Also changes the string reported by (podman load) if all parsing attempts fail, to be only the path instead of dir:path. The error message itself is likely to be the same (from directory.Transport). (While at it, update a mismatched comment.) Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
