Docker

Building with Docker

The samples rely on Docker for the Genvid Services as well as building and running the website. You can either install a version of Docker locally or create a Docker build server directly on Amazon EC2.

While docker-machine is deprecated upstream and the availability of the default AMI for it can change, the Genvid SDK includes an option to create a Docker remote-host using the default AMI. This is a safer alternative when using the Genvid SDK.

To create a new remote Docker instance with a Genvid AMI, use the genvid-ami command with the create-docker-machine option.

genvid-ami create-docker-machine [docker-name]

[docker-name] is a unique name to refer to the machine.

Then use docker-machine installed under bin to control your instance. For example, to terminate your remote instance, run:

bin\docker-machine rm [docker-name]

See Install Docker on Windows if you prefer to use a local installation.

Building Your Project

The Tutorial sample has only a small amount of content. So we can build an archive and make it available for upload under the images subdirectory. This command also builds the website which requires Docker to succeed, so you need to advertise your Docker installation or server.

# On Windows command prompt
@FOR /f "tokens=*" %i IN ('"bin\docker-machine" env [docker-name]') DO @%i

# On bash for Windows
eval $(bin/docker-machine env [docker-name])

# With Powershell
bin/docker-machine env [docker-name] | Invoke-Expression

Where [docker-name] is the name you chose or default if you’re running Docker locally. When the command finishes, you can build the game and the web.

cd samples/cube/directx
py directx.py prepare
py directx.py build-cloud
cd ../web
py web.py build-cloud

This builds two archives in the respective images subdirectory. Note that the script puts a checksum in the image name and removes any old images. A production version of the script should probably be more conservative and keep the old version.
