Installation

Information on how to download and install the Domain Registry project and get a working running instance.

Prerequisites

• A recent version of the Java 7 JDK (note that Java 8 support should be coming to App Engine soon).
• Bazel, which is the buld system that the Domain Registry project uses. The minimum required version is 0.3.1.
• Google App Engine SDK for Java, especially appcfg, which is a command-line tool that runs locally that is used to communicate with the App Engine cloud.
• Create an application on App Engine to deploy to, and set up appcfg to connect to it.

Downloading the code

Start off by grabbing the latest version from the Domain Registry project on GitHub. This can be done either by cloning the Git repo (if you expect to make code changes to contribute back), or simply by downloading the latest release as a zip file. This guide will cover cloning from Git, but should work almost identically for downloading the zip file.

$ git clone git@github.com:google/domain-registry.git
Cloning into 'domain-registry'...
[ .. snip .. ]
$ cd domain-registry
$ ls
apiserving       CONTRIBUTORS  java        LICENSE    scripts
AUTHORS          docs          javascript  python     third_party
CONTRIBUTING.md  google        javatests   README.md  WORKSPACE

The most important directories are:

• docs -- the documentation (including this install guide)
• java/google/registry -- all of the source code of the main project
• javatests/google/registry -- all of the tests for the project
• python -- Some Python reporting scripts
• scripts -- Scripts for configuring development environments

Everything else, especially third_party, contains dependencies that are used by the project.

Building and verifying the code

The first step is to verify that the project successfully builds. This will also download and install dependencies.

$ bazel --batch build //java{,tests}/google/registry/...
INFO: Found 584 targets...
[ .. snip .. ]
INFO: Elapsed time: 124.433s, Critical Path: 116.92s

There may be some warnings thrown, but if there are no errors, then you are good to go. Next, run the tests to verify that everything works properly. The tests can be pretty resource intensive, so experiment with different values of parameters to optimize between low running time and not slowing down your computer too badly.

$ nice bazel --batch test //javatests/google/registry/... \
  --local_resources=1000,3,1.0
Executed 360 out of 360 tests: 360 tests pass.

Deploying the code

You are going to need to configure a variety of things before a working installation can be deployed (see the Configuration guide for that). It's recommended to at least confirm that the default version of the code can be pushed at all first before diving into that, with the expectation that things won't work properly until they are configured.

All of the [EAR](https://en.wikipedia.org/wiki/EAR_(file_format)) and [WAR](https://en.wikipedia.org/wiki/WAR_(file_format)) files for the different environments, which were built in the previous step, are outputted to the bazel-genfiles directory as follows:

$ (cd bazel-genfiles/java/google/registry && ls *.ear)
registry_alpha.ear  registry.ear        registry_sandbox.ear
registry_crash.ear  registry_local.ear

$ (cd bazel-genfiles/java/google/registry && ls *.war)
mandatory_stuff.war           registry_default_local.war
registry_backend_alpha.war    registry_default_sandbox.war
registry_backend_crash.war    registry_default.war
registry_backend_local.war    registry_tools_alpha.war
registry_backend_sandbox.war  registry_tools_crash.war
registry_backend.war          registry_tools_local.war
registry_default_alpha.war    registry_tools_sandbox.war
registry_default_crash.war    registry_tools.war

Note that there is one EAR file per environment (production is the one without an environment in the file name), whereas there is one WAR file per service per environment, with there being three services in total: default, backend, and tools.

Then, use appcfg to deploy the WAR files:

$ cd /path/to/downloaded/appengine/app
$ /path/to/appcfg.sh update /path/to/registry_default.war
$ /path/to/appcfg.sh update /path/to/registry_backend.war
$ /path/to/appcfg.sh update /path/to/registry_tools.war
