Add support for pulling signed images from a version 2 registry.
Only official images within the library namespace will be pull from the
new registry and check the build signature.

This introduces Versions for TarSum checksums.
Fixes: https://github.com/docker/docker/issues/7526
It preserves current functionality and abstracts the interface for
future flexibility of hashing algorithms. As a POC, the VersionDev
Tarsum does not include the mtime in the checksum calculation, and would
solve https://github.com/docker/docker/issues/7387 though this is not a
settled Version is subject to change until a version number is assigned.

Per registry.doRequest, res and client might be nil in case of error
For example, dns resolution errors, /etc/docker/certs.d perms, failed
loading of x509 cert ...
This will make res.StatusCode and res.Body SEGFAULT.

The cli interface works similar to other registry related commands:
docker search foo
... searches for foo on the official hub
docker search localhost:5000/foo
... does the same for the private reg at localhost:5000

This lets you specify custom client TLS certificates and CA root for a
specific registry hostname. Docker will then verify the registry
against the CA and present the client cert when talking to that
registry. This allows the registry to verify that the client has a
proper key, indicating that the client is allowed to access the
images.
A custom cert is configured by creating a directory in
/etc/docker/certs.d with the same name as the registry hostname. Inside
this directory all *.crt files are added as CA Roots (if none exists,
the system default is used) and pair of files <filename>.key and
<filename>.cert indicate a custom certificate to present to the registry.
If there are multiple certificates each one will be tried in
alphabetical order, proceeding to the next if we get a 403 of 5xx
response.
So, an example setup would be:
/etc/docker/certs.d/
└── localhost
├── client.cert
├── client.key
└── localhost.crt
A simple way to test this setup is to use an apache server to host a
registry. Just copy a registry tree into the apache root, here is an
example one containing the busybox image:
http://people.gnome.org/~alexl/v1.tar.gz
Then add this conf file as /etc/httpd/conf.d/registry.conf:
# This must be in the root context, otherwise it causes a re-negotiation
# which is not supported by the tls implementation in go
SSLVerifyClient optional_no_ca
<Location /v1>
Action cert-protected /cgi-bin/cert.cgi
SetHandler cert-protected
Header set x-docker-registry-version "0.6.2"
SetEnvIf Host (.*) custom_host=$1
Header set X-Docker-Endpoints "%{custom_host}e"
</Location>
And this as /var/www/cgi-bin/cert.cgi
#!/bin/bash
if [ "$HTTPS" != "on" ]; then
echo "Status: 403 Not using SSL"
echo "x-docker-registry-version: 0.6.2"
echo
exit 0
fi
if [ "$SSL_CLIENT_VERIFY" == "NONE" ]; then
echo "Status: 403 Client certificate invalid"
echo "x-docker-registry-version: 0.6.2"
echo
exit 0
fi
echo "Content-length: $(stat --printf='%s' $PATH_TRANSLATED)"
echo "x-docker-registry-version: 0.6.2"
echo "X-Docker-Endpoints: $SERVER_NAME"
echo "X-Docker-Size: 0"
echo
cat $PATH_TRANSLATED
This will return 403 for all accessed to /v1 unless *any* client cert
is presented. Obviously a real implementation would verify more details
about the certificate.
Example client certs can be generated with:
openssl genrsa -out client.key 1024
openssl req -new -x509 -text -key client.key -out client.cert

This continues the effort to separate all registry logic from the
deprecated `Server` object.
* 'search' is exposed by `github.com/dotcloud/docker/registry/Service`
* Added proper documentation of Search while I was at it

This is the first step towards separating the registry subsystem from
the deprecated `Server` object.
* New service `github.com/dotcloud/docker/registry/Service`
* The service is installed by default in `builtins`
* The service only exposes `auth` for now...
* ...Soon to be followed by `pull`, `push` and `search`.

roll version and standalone information into the _ping. And to support
Headers they are checked after the JSON is loaded (if there is anything
to load). To stay backwards compatible, if the _ping contents are not
able to unmarshal to RegistryInfo, do not stop, but continue with the
same behavior.

For a pull-only, static registry, there only a couple of headers that
need to be optional (that are presently required.
* X-Docker-Registry-Version
* X-Docker-Size
* X-Docker-Endpoints

RequestFactory is no longer a singleton (can be different for different instances of Registry)
Registry now has an indexEndpoint member
Registry methods that needed the indexEndpoint parameter no longer do so
Registry methods will only use token auth where applicable if basic auth is not enabled.
To improve the use of docker with a private registry the login
command is extended with a parameter for the server address.
While implementing i noticed that two problems hindered authentication to a
private registry:
1. the resolve of the authentication did not match during push
because the looked up key was for example localhost:8080 but
the stored one would have been https://localhost:8080
Besides The lookup needs to still work if the https->http fallback
is used
2. During pull of an image no authentication is sent, which
means all repositories are expected to be private.
These points are fixed now. The changes are implemented in
a way to be compatible to existing behavior both in the
API as also with the private registry.
Update:
- login does not require the full url any more, you can login
to the repository prefix:
example:
docker logon localhost:8080
Fixed corner corner cases:
- When login is done during pull and push the registry endpoint is used and
not the central index
- When Remote sends a 401 during pull, it is now correctly delegating to
CmdLogin
- After a Login is done pull and push are using the newly entered login data,
and not the previous ones. This one seems to be also broken in master, too.
- Auth config is now transfered in a parameter instead of the body when
/images/create is called.
