Playground docker image

README.md

Disposable playground environment

Build

make build

Usage

make [run] [PORT_MAPPING=<container_port>:<host_port>]

The default Makefile rule (try) runs a disposable docker container, use run to keep the container.

PORT_MAPPING defaults to 80:8000.

/tmp/playground is mapped to ~user/playground.

TODO ...

For macOS

Use DISPLAY=$ip:0 after starting XQartz. Possibly use xhost + $ip on the host.
