base-platform

Base Docker image for tsuru platforms. It creates the required structure for tsuru platforms:

• create the ubuntu user
• create the /home/application directory
• properly set paths permissions
• install deploy-agent
• place the base deploy script in the path /var/lib/tsuru/base/deploy

The image also provides the following required components:

deploy-agent

This is the agent responsible for establishing connection between application containers and the tsuru API. See tsuru/deploy-agent for more details.

base deploy script

This base script does the following steps:

1. Downloads the archive provided by the tsuru API
2. Extracts it in the /home/application/current directory
3. Install operating system dependencies
4. Handle default Procfiles (stored in the directory /var/lib/tsuru/default)

It's possible to build platforms that do not use this image, but you need to ensure that deploy-agent is installed, and that you provide a deploy script that does everything that the base deploy script does.

You may also invoke the install and deploy scripts manually, as the buildpack platform does: https://github.com/tsuru/platforms/blob/master/buildpack/Dockerfile.
