I first saw |
|
|
 |
kubedoom (https://github.com) |
|
|
|
and thought it was pretty cool, so I decided to do the same for Terraform, knowing that I was working with it for professional projects. |
|
|
|
|
|
|
|
The principle is very simple, each enemy represents a Terraform resource, if an enemy dies, the associated resource is destroyed. |
|
|
|
|
|
|
|
## How it works ? |
|
|
|
|
|
|
|
The main program is `tf-doom`', which creates a UNIX socket, listens to it and simultaneously launches an X11 virtual server (Xvfb), a VNC server (x11vnc) attached to this X session and `psdoom` (DOOM writing to the UNIX socket). |
|
|
|
|
|
|
|
Everything we've just described will be encapsulated in a Docker container. |
|
|
|
|
|
|
|
The binaries `Xvfb` and `x11vnc` are used to create a cross-platform graphical access to `psdoom` inside the container. |
|
|
|
|
|
|
|
`psdoom` will continuously write to the UNIX socket to signal `tf-doom` to send Terraform resource information. When an enemy is killed, `psdoom` writes the associated resource name to the socket. |
|

## Demo |

|
|
This demo has been realized with the test Terraform project, every steps to reproduce it are detailed in the README file on the repository. |
