* Add container runlabel commandbaude2018-09-28
| | | | | | | | | | | | | Execute the command as described by a container image. The value of the label is processed into a command by: 1. Ensuring the first argument of the command is podman. 2. Substituting any variables with those defined by the environment or otherwise. If no label exists in the container image, nothing is done. podman container runlabel LABEL IMAGE extra_args Signed-off-by: baude <bbaude@redhat.com>
* run complex image names with short namesbaude2018-09-28
| | | | | | | | | | | | | In cases where the image name is more complex like: quay/baude/alpine_nginx:latest and is not from the docker registry, we need to be able to run the image by its shortname such as baude/alpine_nginx. The same goes when the image is not from a registry but instead has the localhost repository. This resolves buildah issue #1034 Signed-off-by: baude <bbaude@redhat.com>

* Fix ambiguity in adding localhost to podman savehaircommander2018-08-08
| | | | | | | | | | | ...and some naming decisions. This change ensures podman save doesn't incorrectly prepend localhost when saving an image. Signed-off-by: haircommander <pehunt@redhat.com> Closes: #1140 Approved by: rhatdan
* 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
* 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

* Add a *types.SystemContext parameter to getCopyOptions and DRO.GetSystemContextMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | All callers of getCopyOptions also call GetSystemContext with the same three parameters; we will want to simplify this by passing the first SystemContext to getCopyOptions, which can then inherit this data instead of so many parameters everywhere. For now, just add a *types.SystemContext parameter without using it. Should not change behavior (but does not add unit tests).

* Move pullImage from Image to RuntimeMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | pullImage (now) only uses Image.InputName; it is really used to _create_ an Image object, based on the pull results (as is most visible in the LoadFromArchive caller), so it should not be a method on it. This also simplifies a bit the number of different kids of uses of Image.InputName; still apparently not enough to clearly document the field, though. Should not change behavior.

* RFC: Rename Image.PushImage to Image.PushImageToHeuristicDestinationMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | | | | | 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? - varlink ExportImage says "destination must have transport type"; should it be using alltransports.ParseImageReference + PushImageToReference, then? (While touching the call in cmd/podman, also remove a commented-out older version of the call.) Should not change behavior (but does not add unit tests).

* Remove an unnecessary use of alltransports.ParseImageNameMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | When the string is formatted including a constant transport name, just call the transport to create or parse a reference explicitly. This avoids unnecessary string formatting and parsing. Then drop image.TarballTransport, which has no remaining users. Should not change behavior (but does not add unit tests). Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Split Image.PushImageToReference from Image.PushImageMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | This retains the existing string parsing heuristic for users who must continue to use it (notably the varlink API - or is it still subject to change?), but allows callers who can get precise references to supply them without having to deal with string formatting. Should not change behavior (but does not add unit tests). Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Don't format to string and re-parse a DockerReference()Miloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | We already have a c/image/docker/reference.Named; no need to round-trip it through a string. This also eliminates the theoretical parsing failure, and the unchecked .(reference.Named) cast. Also add a check for DockerReference() == nil to be extra paranoid, although that should never happen. Should not change behavior (but does not add unit tests). Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Remove the :// end from DockerTransportMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | | | | | | (... but keep it in DefaultTransport, which remains irregular.) This makes DockerTransport consistent with the others, and much more importantly, allows several instances to do > imgRef.Transport().Name() == DockerTransport instead of the current > strings.HasPrefix(DockerTransport, imgRef.Transport().Name()) , which currently works but is pretty nonsensical (it does not check the "docker://" prefix against the _full reference_, but it checks the _transport name_ as a prefix of "docker://", i.e. a transport named "d" would be accepted. Should not change behavior, because the only currently existing transport which has a name that is a prefix of "docker://" is c/image/docker.Transport (but does not add unit tests).

* Strip transport from image name when looking for local imagebaude2018-04-26
| | | | | | | | | | | When a user pulls an image using a transport, like docker-daemon, we try to lookup the new image in storage by the input name after the pull.

* Removing tagged images change in behaviorbaude2018-03-22
| | | | | | | | | | | | | | | An image name is really just a tag. When an image has multiple tags, we should be able to "delete" the one of its tags without harm. In this case, the "delete' is really a form of Untag (removing the tag from the image). If an image has multiple tags and the user tries to delete by ID without force, this should be denied because when you delete by ID there is no distinguishing it like image tags.

| | | | | | | | | | | | | This represents the stage3 implementation for the image library. At this point, we are moving the image-centric functions to pkg/image including migration of args and object-oriented references. This is a not a one-for-one migration of funcs and some funcs will need to continue to reside in runtime_img as they are overly specific to libpod and probably not useful to others.

* Image Resolution Stage 1baude2018-03-08
This is the stage 1 effort for an image library that can be eventually used by buildah and podman alike. In eventuality, the main goal of the library (package) is to: * provide a consistent approach to resolving image names in various forms (from users). * based on the result of the above, provide image methods that in a singular spot but separate from the runtime. * reduce the cruft and bloat in the current podman runtime. The goal of stage 1 is to demonstrate fast, accurate image resolution for both local and remote images resulting in an image object as part of the return.
