Although there exist many step-by-step instructions on installing and configuring `rvm` for most Linux distros, there aren't many focused on Alpine "daily drivers". + +So this post is more or less a helpful document for my future self. If it happens to help others then that's an added bonus! + +## Simple Setup + +Make sure you have the basic packages first: + +``` +apk update +apk add curl gcc gnupg gpg dirmngr procps musl-dev linux-headers zlib zlib-dev openssl openssl-dev libssl1.1 +``` + +Next download the latest `stable` version of `rvm` from Github, unpack it, place it in the proper user directory (~/.rvm) and install any required libs: + +``` +curl -sSL https://github.com/rvm/rvm/tarball/stable -o rvm-stable.tar.gz +echo 'export rvm_prefix="$HOME"' > ~/.rvmrc +echo 'export rvm_path="$HOME/.rvm"' >> ~/.rvmrc +mkdir rvm && cd rvm +tar --strip-components=1 -xzf ../rvm-stable.tar.gz +./install --auto-dotfiles --autolibs=0 +``` + +Now we can remove everything and properly link to `rvm`: + +``` +cd ../ && rm -rf rvm-stable stable.tar.gz rvm +source ~/.rvm/scripts/rvm +``` + +Now you can freely install any version of Ruby that you desire! + +``` +rvm install ruby-X.X.X +``` |
