Let's recreate https://go.dev/play. The challenge will be to create a proper isolated execution environment.
What do we need?
- a server
- a container to run
go run <code> - at least two shared volumes. One r/w for the code and a read-only for bind-mounting go
How should it work?
- A browser gets some html at /
- user adds go code to a textarea and then sends it to the server at /code
- server puts the code on disk
- server runs
docker run ... <code-path>and returns stdout to the browser - browser displays the result
$ go run server.go
- thoughts on scaling
- bonus: let the user save the code
- preserve line terminators in output
- docker run --help for dropping permissions
