* change from sysregistries to sysregistriesv2Daniel J Walsh2019-05-03
| | | | | | | | We want to start supporting the registries.conf format. Also start showing blocked registries in podman info Fix sorting so all registries are listed together in podman info. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Set blob cache directory based on GraphDriverDaniel J Walsh2019-03-29
| | | | | | | | | | | | Currently in rootless containers, we end up not using the blob cache. We also don't store the blob cache based on the users specified graph storage. This change will cause the cache directory to be stored with the rest of the containe images. While doing this patch, I found that we had duplicated GetSystemContext in two places in libpod. I cleaned this up. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Add event logging to libpod, even display to podmanbaude2019-03-11
| | | | | | | | | | | | | | | | | In lipod, we now log major events that occurr. These events can be displayed using the `podman events` command. Each event contains: * Type (container, image, volume, pod...) * Status (create, rm, stop, kill, ....) * Timestamp in RFC3339Nano format * Name (if applicable) * Image (if applicable) The format of the event and the varlink endpoint are to not be considered stable until cockpit has done its enablement.

| | | | | | | | | | The toolbox project would benefit from a few changes to more closely resembe the original atomic cli project. Changes made are: * only pull image for container runlabel if the label exists in the image * if a container image does not have the desired label, exit with non-zero Signed-off-by: baude <bbaude@redhat.com>
* Use getPullRefPair / getSinglePullRefPairGoal in ↵Miloslav Trmač2019-01-14
| | | | | | | | | | | | | | | | | pullGoalFromPossiblyUnqualifiedName This shortens the code a bit, but most importantly ensures that all pulls from docker.Transport are processed exactly the same way, and there is only a single store.ParseStoreReference in the pull code. It's a bit wasteful to call decompose() in getPullRefPair just after pullGoalFromPossiblyUnqualifiedName has qualified the name, but on balance only having exactly one code path seems worth it. Alternatively we could split getPullRefPairToQualifiedDestination from getPullRefPair. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Use imageParts.referenceWithRegistry in pullGoalFromPossiblyUnqualifiedNameMiloslav Trmač2019-01-14
| | | | | | | | | | | | | | | | | | | CHANGES BEHAVIOR. This bypasses .assemble, and preserves the original lack of tag / original digest instead of adding :latest/:none (still subject to ParseStoreReference normalization). Using the original digest seems clearly correct; dropping the :latest suffix from .image strings, and adding /library to docker.io/shortname, only affects user-visible input; later uses of the return value of pullImageFrom... use ParseStoreReference, which calls reference.ParseNormalizedNamed and reference.TagNameOnly, so the image name should be processed the same way whether it contains a tag, or libray/, or not. This also allows us to drop the problematic hasShaInInputName heuristic/condition/helper. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Use imageParts.referenceWithRegistry in getPullRefPairMiloslav Trmač2019-01-14
| | | | | | | | | | | | | | | | CHANGES BEHAVIOR.

* Don't use imageParts.assemble when pulling from a qualified nameMiloslav Trmač2019-01-14
| | | | | | | | | | | | | | | | | | | | | | | CHANGES BEHAVIOR. If the name is qualified, instead of decomposing it into components and re-assembling, just use the input name unmodified: - For name:tag values, .assemble() just recreates the input. - For untagged values, .assemble() adds ":latest"; we keep the input as is, but both docker.ParseReference and storage.Transport.ParseStoreReference use reference.TagNameOnly() already. - For digested references, .assemble() adds ":none", but the code was already bypassing .assemble() on that path already - for the source reference. For the destination, this replaces a :none destination with a the @digest reference, as expected. Note that while decompose() has already parsed the input, it (intentionally) bypassed the docker.io/library normalization; therefore we parse the input again (via docker.ParseReference) to ensure that the reference is normalized. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Simplify pullGoalFromPossiblyUnqualifiedNameMiloslav Trmač2019-01-14
| | | | | | | | | | Both imageParts and this function implicitly assume docker.Transport troughout, so instead of pretending to be flexible about DefaultTransport, just hard-code docker.ParseReference directly. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Remove imageParts.transportMiloslav Trmač2019-01-14
| | | | | | | | | | It is only ever set to DefaulTransport, and all of the code is docker/reference-specific anyway, so there's no point in making this a variable. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Simplify pullGoalFromPossiblyUnqualifiedNameMiloslav Trmač2019-01-14
| | | | | | | | | | After inlining assembleWithTransport, we have two branches with the same prepending of decomposedImage.transport; move that out of the branches. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Inline imageParts.assembleWithTransport into callersMiloslav Trmač2019-01-14
| | | | | | | | | | | | | imageParts.transport is a constant, and the design of imageParts is not transport-independent in any sense; we will want to eliminate the transport member entirely. As a first step, drop assembleWithTransport and inline an exact equivalent into all callers. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Drop image.DecomposeString, make image.Parts private imageParts againMiloslav Trmač2019-01-14
| | | | | | | | | Now that DecomposeString has no users, make the type private again. Any new users of it should come with a rationale - and new users of the "none"/"latest" handling of untagged/digested names that is currently implemented should have an exceptionaly unusual rationale.

* Remove manual handling of insecure registries in doPullImageMiloslav Trmač2018-12-06

* Remove the forceSecure parameter on the pull call stackMiloslav Trmač2018-12-06
| | | | | | | DockerRegistryOptions.DockerInsecureSkipTLSVerify as an types.OptionalBool can now represent that value, so forceSecure is redundant. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
* Minimally update for the DockerInsecureSkipTLSVerify type changeMiloslav Trmač2018-12-06
| | | | | | | | | | | | | | | | | Following SystemContext.DockerInsecureSkipTLSVerify, make the DockerRegistryOne also an OptionalBool, and update callers. Explicitly document that --tls-verify=true and --tls-verify unset have different behavior in those commands where the behavior changed (or where it hasn't changed but the documentation needed updating). Also make the --tls-verify man page sections a tiny bit more consistent throughout. This is a minimal fix, without changing the existing "--tls-verify=true" paths nor existing manual insecure registry lookups. Signed-off-by: Miloslav Trmač <mitr@redhat.com>

* libpod/image/pull: Return image-pulling errors from doPullImageW. Trevor King2018-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were already writing these to our debug logs. But collecting them and including them in the error message will make it easier for callers who don't have debugging enabled to figure out what's going wrong. Using multierror gives us both pretty formatting (when we print this for the user) and programmatic access (for any callers that need to inspect the constituent errors). With this commit and a config like: $ cat /etc/containers/registries.conf [registries.search] registries = ['registry.access.redhat.com', 'quay.io', 'docker.io'] pulling an unqualified missing image looks like: $ podman pull does-not/exist Trying to pull registry.access.redhat.com/does-not/exist:latest...Failed Trying to pull quay.io/does-not/exist:latest...Failed Trying to pull docker.io/does-not/exist:latest...Failed error pulling image "does-not/exist": unable to pull does-not/exist: 3 errors occurred: * Error determining manifest MIME type for docker://registry.access.redhat.com/does-not/exist:latest: Error reading manifest latest in registry.access.redhat.com/does-not/exist: unknown: Not Found * Error determining manifest MIME type for docker://quay.io/does-not/exist:latest: Error reading manifest latest in quay.io/does-not/exist: unauthorized: access to the requested resource is not authorized * Error determining manifest MIME type for docker://does-not/exist:latest: Error reading manifest latest in docker.io/does-not/exist: errors: denied: requested access to the resource is denied unauthorized: authentication required A qualified image looks like: $ podman pull quay.io/does-not/exist Trying to pull quay.io/does-not/exist...Failed error pulling image "quay.io/does-not/exist": unable to pull quay.io/does-not/exist: unable to pull image: Error determining manifest MIME type for docker://quay.io/does-not/exist:latest: Error reading manifest latest in quay.io/does-not/exist: unauthorized: access to the requested resource is not authorized If one of the searched repositories was offline, you'd get a more useful routing error for that specific registry. For example: $ cat /etc/hosts 127.0.0.1 quay.io $ podman pull does-not/exist Trying to pull registry.access.redhat.com/does-not/exist:latest...Failed Trying to pull quay.io/does-not/exist:latest...Failed Trying to pull docker.io/does-not/exist:latest...Failed error pulling image "does-not/exist": unable to pull does-not/exist: 3 errors occurred: * Error determining manifest MIME type for docker://registry.access.redhat.com/does-not/exist:latest: Error reading manifest latest in registry.access.redhat.com/does-not/exist: unknown: Not Found * Error determining manifest MIME type for docker://quay.io/does-not/exist:latest: pinging docker registry returned: Get https://quay.io/v2/: dial tcp 127.0.0.1:443: connect: connection refused * Error determining manifest MIME type for docker://does-not/exist:latest: Error reading manifest latest in docker.io/does-not/exist: errors: denied: requested access to the resource is denied unauthorized: authentication required This is our first direct dependency on multierror, but we've been vendoring it for a while now because opencontainers/runtime-tools uses it for config validation.

* 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
* clarify pull error messagebaude2018-08-02
| | | | | | | | | | | | | 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.

* 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. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* 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
* 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.

* Split doPullImage from pullImageMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | Now that we have a pullGoal, separate determination of the goal from performing it; we will then introduce another entry point with a supplied types.ImageReference.

* 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.

* Do not re-parse the list of search registries just for an error messageMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | ... when we even only count them. This eliminates a rare error case, and saves time re-reading and re-parsing the input. (We still compute registryPath redundantly, and it may get out of sync.) Should not change behavior (but does not add unit tests).

* Eliminate duplicate determination whether to use search registriesMiloslav Trmač2018-08-01

* Eliminate the "DockerArchive means pull all refPairs" special caseMiloslav Trmač2018-08-01

* Introduce struct pullGoalNamesMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | | This is an intermediate version of pullGoal, which exists basically only for easier testing without containers-storage: (i.e. root access) in unit tests. Like pullGoal, we will add more members to make it useful in the future. RFC: Unlike pullGoal, the return value is *pullGoalNames, because there are quite a few (return nil, err) cases which would be more difficult to read when returning a value. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Introduce struct pullGoalMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | The eventual goal is to cleanly capture semantics like "pull all images for DockerArchive" and "did a search through $registries" without hard-coding it through; and to allow a pullImage variant where the caller can pass an imageReference directly. For now, this just wraps []pullRefPair and should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Use []pullRefPair instead of []*pullRefPairMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | We are passing the values, don't really need the pointer sharing semantics, and the structures are small enough, and the arrays short enough, that we very likely lose on the indirect accesses more than we save on quicker copying of the slices when extending them. Value semantics is safer anyway. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
