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.

## Build the development environment

## Configure the development environment
|

|
||||
The first prerequisite of properly building distribution targets is to have a Go
|
||||
development environment setup. Please follow [How to Write Go Code](https://golang.org/doc/code.html)
|
||||
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:
|
||||
Next, fetch the code from the repository using git:
|
||||
|
||||
go get github.com/distribution/distribution/cmd/registry
|
||||
git clone https://github.com/distribution/distribution
|
||||
cd distribution
|
||||
|
||||
The above will install the source repository into the `GOPATH`.
|
||||
If you are planning to create a pull request with changes, you may want to clone directly from your [fork](https://help.github.com/en/articles/about-forks).

## Build and run from source

First, build the binaries:

For the full development experience, one should `cd` into
|
||||
`$GOPATH/src/github.com/distribution/distribution`. From there, the regular `go`
|

commands, such as `go test`, should work per package (please see

The regular `go` commands, such as `go test`, should work per package.

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

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

directory. We can verify this worked by running
|
||||
the registry binary generated in the "./bin" directory:
|
||||
|
||||
$ ./bin/registry --version
|
||||
./bin/registry github.com/distribution/distribution v2.0.0-alpha.2-80-g16d8b2c.m
|

|
||||
Run `make test` to run all of the tests.
|
||||
|
||||
Run `make validate` to run the validators, including the linter and vendor validation. You must have docker with the buildx plugin installed to run the validators.
