Folders will contain small programs. Dockerfile.example
is template for Dockerfile used in the folder to create application inside the Docker container.
$ docker build -t my-rust-app .
$ docker run -it --rm --name my-running-app my-rust-app
There may be occasions where it is not appropriate to run your app inside a container. To compile, but not run your app inside the Docker instance, you can write something like:
$ docker run --rm --user "$(id -u)":"$(id -g)" -v "$PWD":/usr/src/myapp -w /usr/src/myapp rust:1.23.0 cargo build --release
This will add your current directory, as a volume, to the container, set the working directory to the volume, and run the command cargo build --release. This tells Cargo, Rust's build system, to compile the crate in myapp and output the executable to target/release/myapp.

Simple Hello World!
example in Rust. Build Docker container docker build -t hello-world-rust .
and run the container docker run -it --rm --name hello-world-rust-app hello-world-rust
