The skopeo sync command can sync images between a SOURCE and a
destination.
The purpose of this command is to assist with the mirroring of
container images from different docker registries to a single
docker registry.
Right now the following source/destination locations are implemented:
* docker -> docker
* docker-> dir
* dir -> docker
The dir location is supported to handle the use case
of air-gapped environments.
In this context users can perform an initial sync on a trusted machine
connected to the internet; that would be a `docker` -> `dir` sync.
The target directory can be copied to a removable drive that can then be
plugged into a node of the air-gapped environment. From there a
`dir` -> `docker` sync will import all the images into the registry serving
the air-gapped environment.
Notes when specifying the `--scoped` option:
The image namespace is changed during the `docker` to `docker` or `dir` copy.
The FQDN of the registry hosting the image will be added as new root namespace
of the image. For example, the image `registry.example.com/busybox:latest`
will be copied to
`registry.local.lan/registry.example.com/busybox:latest`.
The image namespace is not changed when doing a
`dir:` -> `docker` sync operation.
The alteration of the image namespace is used to nicely scope images
coming from different registries (the Docker Hub, quay.io, gcr,
other registries). That allows all of them to be hosted on the same
registry without incurring in clashes and making their origin explicit.

This image is about 100 MB instead of about 2 GB for the Server Core,
decreasing disk requirements and hopefully significantly speeeding up
integration tests.

Add a --all/-a flag to instruct us to attempt to copy all of the
instances in the source image, if the source image specified to "skopeo
copy" is actually a list of images. Previously, we'd just try to locate
one for our preferred OS/arch combination.
Add a couple of tests to verify that we can copy an image into and then
back out of containers-storage. The contents of an image that has been
copied out of containers-storage need a bit of tweaking to compensate
for containers-storage's habit of returning uncompressed versions of the
layer blobs that were originally written to it, in order to be
comparable to the image as it was when it was pulled from a registry.

Since GPG 2.1, GPG asks for a passphrase by default; opt out when
generating test keys to avoid
> gpg: agent_genkey failed: No pinentry
> gpg: key generation failed: No pinentry
which happens otherwise (and we can't use an interactive pinentry
in a batch process anyway).

This effectively reverts f4a44f00b8 ("integration: disable check with
image-tools for image-spec RC5"), which disabled the compliance
validation due to upstream bugs. Since those bugs have been fixed,
re-enable the tests (to make the smoke tests far more effective).

We are not testing registry start-up performance, and killing the test
suite just because Travis is a bit busy doesn’t help; we’re much better
off with a test run which gives the registry a bit more time.
Move "skip if signing is not available" into the test, there may be
tests which only need verification.
Move GNUPGHOME creation from SetUpTest to SetUpSuite, sharing a single
key is fine. We don’t change the GNUPGHOME contents at test runtime.
Now that we can update the embedded name:tag, the test no longer fails
on a schema1→schema1 copy with the old schema1 server which verifies the
name:tag value.
Before the update, we have loosened the equality check to ignore the
name/tag; now that we are generating them correctly, test for the
expected values.
TestCopySignatures, among other things, tests handling of a correctly
signed image to a different name without breaking the signature, which
will be impossible with schema1 after we start updating the names
embedded in the schema1 manifest. So, use the schema2 server binary,
and docker://busybox image versions which use schema2.
The new version of containers/image will update the name and tag fields
when pushing to schema1; so accept that before we update, so that tests
keep working.
For now, just ignore the name/tag fields, so that both the current and
updated versions of containers/image are acceptable; we will tighten
that after the update.
Use (diff -x manifest.json) instead of removing the manifest.json files.
Also rename the helper from destructiveCheckDirImageAreEqual to
assertDirImagesAreEqual.
In addition to the default registry in the OpenShift cluster, start two
more (one known to support s1 only, one known to support s1+s2), and
also a docker/distribution s1-only registry.
Then test that copying images around works as expected.
NOTE: The docker/distribution s1-only tests currently fail and are
disabled. See the added comment for details.
We don’t really need to differentiate between the master/registry, we
just want to terminate them, maybe in the right order. So, collect them
in an array instead of using separate members.
This will make it easier to have more registry instances in the near
future.

The *check.C object can not be reused across tests, so storing it in
openshiftCluster is incorrect (and leads to weird behavior like
assertion failures being silently ignored). So far this hasn't really
been an issue because we have been using the *check.C only in SetUpSuite
and TearDownSuite, and the changes to this have turned out to be
unnecessary after all, but this is still the right thing to do.
This is more or less
> s/c\./cluster\./g; s/cluster\.c/c/g
(paying more attention to the syntax) and corresponding modifications
to the method declarations.
Does not change behavior, apart from using the correct *check.C in
CopySuite.TearDownSuite.
This makes the fixture editation more robust against typos or unexpected
changes (if the “fixture” comes from third parties, like the OpenShift
registry configuration file).
This separates creation of the account and configuration, which can be
shared across service instances, from actually starting the registry; we
will soon start several of them.
Only splits a function, does not change behavior.
… testing signature reading and writing using the
X-Registry-Supports-Signatures extension, and its
interoperability/equivalence with the atomic: native OpenShift API.
Primarily vendor after merging mtrmac/image:openpgp.
Then update for the SigningMechanism API change.
Also skip signing tests if the GPG mechanism does not support signing.
Also abort some of the tests early instead of trying to use invalid (or
nil) values.
The current master of image-tools does not build with Go 1.6, so keep
using an older release.
Also requires adding a few more dependencies of our updated
dependencies.
