This is useful if you intend to actively work on the registry. Most people should use the . People looking for advanced operational use cases might consider rolling their own image with a custom Dockerfile inheriting `FROM registry:2`. OS X users who want to run natively can do so following . You are expected to know your way around with go & git. If you are a casual user with no development experience, and no preliminary knowledge of go, building from source is probably not a good solution for you. The first prerequisite of properly building distribution targets is to have a Go development environment setup. Please follow for proper setup. If done correctly, you should have a GOROOT and GOPATH set in the environment. If a Go development environment is setup, one can use `go get` to install the `registry` command from the current latest: go get github.com/docker/distribution/cmd/registry The above will install the source repository into the `GOPATH`. Now create the directory for the registry data (this might require you to set permissions properly) mkdir -p /var/lib/registry ... or alternatively `export REGISTRYSTORAGEFILESYSTEM_ROOTDIRECTORY=/somewhere` if you want to store data into another location. The `registry` binary can then be run with the following: $ $GOPATH/bin/registry --version $GOPATH/bin/registry github.com/docker/distribution v2.0.0-alpha.1+unknown NOTE: While you do not need to use `go get` to checkout the distribution project, for these build instructions to work, the project must be checked out in the correct location in the `GOPATH`. This should almost always be `$GOPATH/src/github.com/docker/distribution`. The registry can be run with the default config using the following incantation: $ $GOPATH/bin/registry serve $GOPATH/src/github.com/docker/distribution/cmd/registry/config-example.yml INFO[0000] endpoint local-5003 disabled, skipping app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown INFO[0000] endpoint local-8083 disabled, skipping app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown INFO[0000] listening on :5000 app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown INFO[0000] debug server listening localhost:5001 If it is working, one should see the above log messages. For the full development experience, one should `cd` into `$GOPATH/src/github.com/docker/distribution`. From there, the regular `go` commands, such as `go test`, should work per package (please see if they don't work). A `Makefile` has been provided as a convenience to support repeatable builds. Please install the following into `GOPATH` for it to work: go get github.com/golang/lint/golint Once these commands are available in the `GOPATH`, run `make` to get a full build: $ make clean fmt vet lint build github.com/docker/docker/vendor/src/code.google.com/p/go/src/pkg/archive/tar github.com/sirupsen/logrus github.com/docker/libtrust ... github.com/yvasiyarov/gorelic github.com/docker/distribution/registry/handlers github.com/docker/distribution/cmd/registry test ... ok github.com/docker/distribution/digest 7.875s ok github.com/docker/distribution/manifest 0.028s ok github.com/docker/distribution/notifications 17.322s ? github.com/docker/distribution/registry [no test files] ok github.com/docker/distribution/registry/api/v2 0.101s ? github.com/docker/distribution/registry/auth [no test files] ok github.com/docker/distribution/registry/auth/silly 0.011s ... /Users/sday/go/src/github.com/docker/distribution/bin/registry /Users/sday/go/src/github.com/docker/distribution/bin/registry-api-descriptor-template binaries The above provides a repeatable build using the contents of the vendor directory. This includes formatting, vetting, linting, building, testing and generating tagged binaries. We can verify this worked by running the registry binary generated in the "./bin" directory: $ ./bin/registry --version ./bin/registry github.com/docker/distribution v2.0.0-alpha.2-80-g16d8b2c.m Optional can be provided using the environment variable `DOCKER_BUILDTAGS`.
