unluac-d: Dockerized Luac decompiler

Dockerized versions of unluac for decompiling luac files from wherigo containers regardless of the execution environment.

Currently, dockerizes an old binary version unluac_2015_06_13.jar in two ways:

• unluac-docker/ a dockerfile for creating 'standard' docker image that
  • reads input (luac file to decompile) from bind-mount and
  • prints results to STDOUT
• unluac-docker-faas/ a dockerfile (based on unloac-docker) for creating "function-as-a-service" docker image where unluac is wrapped with OpenFaas's function watchdog to
  • read input (luac file to decompile) from HTTP POST request
  • send results to HTTP POST response

The purpose is to make it easy to decompile luac files extracted from wherigo containers regardless of the execution environment.

Usage

unluac-docker:

Build docker image

cd unluac-docker && docker build -t mrummuka/unluac-docker .

Run docker container to decompile luac

docker run --rm -v /path/to/luacdir/:/data mrummuka/unluac-docker:latest

Note: unluac-docker expects to find cartridge.luac in /path/to/luacdir/

unluac-docker-faas:

Build docker image

cd unluac-docker-faas && docker build -t mrummuka/unluac-docker-faas .

Start docker container

docker run --rm -p 8080:8080 mrummuka/unluac-docker-faas:latest

Decompile using unluac-docker-faas

`curl -XPOST --data-binary @cartridge.luac localhost:8080 -o output.file`
