+# Installing Ruby with RVM on Alpine Linux
+
+2023-03-16
+
+For some on-going projects I need to switch to different versions of `ruby`. 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
+```
