# With Docker
make

Details

Clone this repo:

git clone https://github.com/creack/corewar
cd corewar

Run:

env -i HOME=${HOME} PATH=${PATH} go tool wasmserve ./vm

For development, wasmer exposes an endpoint to do live reload.

I recommend reflex.

With wasmer running, run:

go tool reflex curl -v http://localhost:8080/_notify

Docker

A Dockerfile is provided to build and run the WASM version.

Build

docker build -t corewar .

Regular run

To run the image, make sure to have:

• --rm to avoid pollution
• -it so the app receives signals
• -p to expose the port 8080

Any changes to the code will require to re-build the image.

docker run --rm -p 8080:8080 -it corewar wasmserve .

You can then access the WASM page at the Docker ip on port 8080. If in doubt about the IP, it is likely localhost.

Development run

For development, you can add -v $(pwd):/app to mount the local directory in the Docker container, the server will hot-reload when file changes.

docker run --rm -p 8080:8080 -it -v $(pwd):/app corewar
