A series of simple Docker images containing Swift and optionally extra dependencies. The dependencies are pre-fetched but not pre-built.
To launch, place (at least) a main.swift in your working directory and run:
docker run -it --rm -v "$PWD":/pg/src bygri/swift4-playground
Then, when the container has launched, type swift run.
If you want custom dependencies, put a Package.swift in your working directory, main.swift in a src directory, and run:
docker run -it --rm -v "$PWD":/pg bygri/swift4-playground
bygri/swift4-playground: Just Swift 4.0.3.
bygri/vapor2-playground: Latest Vapor 2 and Swift 4.0.3.
