🧪 Docker Playground

Once you have built a container image (madlad-custom in the example below) you can drop into an interactive session and experiment with anything that lives inside – from running a quick MadGraph job to plotting histograms on the fly – it has everything you need (including ROOT).

1️⃣ Launch the Container

# Start an interactive bash session inside the container.
#   - `--rm`  → remove the container when you exit
#   - `-it`   → keep STDIN open and allocate a TTY
#   - `-v $PDW:/root`  → mount your current working directory (or any other folder)
#   - `madlad-custom`  → the image name you built
docker run --rm -it -v $PDW:/root madlad-custom bash

Tip – If you don’t have a $PDW environment variable, just replace it with the absolute path of any directory you want to expose inside the container.
E.g. -v $(pwd):/root.

Once you’re inside, the shell is just like a normal Linux terminal. The full MadLAD toolchain is already installed and ready to use.

2️⃣ “Hello, MadGraph”
