Unable to locate `rustup` binary on Docker machine

[johnnyman727]

I'm hoping to install rustup on a Docker container.

Here are the commands I run:

RUN curl -s https://static.rust-lang.org/rustup.sh > /home/install.sh
RUN chmod +x /home/install.sh
RUN sh /home/install.sh -s -- --default-toolchain nightly

It appears to install both cargo and rustc properly but not rustup. Additionally, there is no .cargo folder created as I would expect.

Oh the rustup.sh script doesn't actually install this rustup project. To do that you'll want to download from https://sh.rustup.rs

I installed rust in docker with: curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain stable -y but rustup isn't available

# rustup
bash: rustup: command not found

@grigio You would need to add CARGO_HOME/bin to your PATH.
