Deploying Gerrit to Google App Engine
=====================================

To deploy Gerrit to a new (or an upgrade for an existing) Google
App Engine instance:

----
	make update APPID=your-application-id ADMIN=your@email
----

where "your-application-id" is the unique application id you chose
for the application instance at the time you registered it with
Google App Engine;

and where "your@email" is a Google Account username that is
registered as a developer/administrator of the Google App Engine
instance identified by $APPID.


Saving Configuration
--------------------

If you are frequently deploying via the same user account or to the
same instance you may want to save your configuration options into
a local config.mak file:

----
	$ cat config.mak
	ADMIN = your@email
	APPID = your-application
----

as these parameters can then be left off of the make update
command line:

----
	make update
----


Admin Only Lockout
------------------

When updating a Google App Engine instance Gerrit can be configured
to only permit admin logins.  This may be useful when setting up
a testing/development environment, where external users are not
desired yet.

Simply set ADMIN_ONLY=1 when running the build:

----
	make update ADMIN_ONLY=1 [other options...]
----

You may wish to have this configured in your config.mak file:

----
	$ cat config.mak
	ifeq ($(APPID),your-private-id)
		ADMIN_ONLY=1
	endif
----

This way the lockout is automatically enabled when you run a build.

To disable the lockout, run "make update" without ADMIN_ONLY set
(e.g. delete or comment it out from your config.mak file).


Special Options
---------------

When deploying to an internal Google App Engine instance you may
need to set APPCFG_OPTS to point to the internal admin console.
This is best configured in your config.mak file:

----
	$ cat config.mak
	ADMIN = you@google.com
	APPID = your-application

	ifeq ($(APPID),internal-app-id)
		APPCFG_OPTS = -s admin-console.some.internal.host.name
	endif
----

As a Googler you will need to search the intranet to locate the
correct hostname for the internal admin-console, or ask someone who
is involved with Gerrit or the Google App Engine team for the name.
