I'm trying to install azure cli using python 3.10 in docker on alpine, but I'm getting a

How is build different from runtime? If I run the same commands on a running alpine container, then everything works and gets installed as intended?

You don't generally use version managers like rbenv in Docker. There are a couple of reasons for this. One is that an image usually only contains a single application and its single runtime, so you'd never have more than one Ruby in an image and therefore there's no need to switch. A second is that most common paths of running containers (including docker run and the Dockerfile RUN directive) don't look at shell dotfiles like .bashrc or /etc/profile, so the version manager setup will never get run.
TruffleRuby is distributed (among other ways) as a standalone tar file so you can just install that in your Dockerfile. I'd make the Dockerfile look roughly like:
FROM debian:buster-slim
# Install the specific dependency packages TruffleRuby recommends
# (build-essential is much larger but might actually be necessary)
RUN apt-get update \
&& DEBIAN_FRONTEND=noninteractive \
apt-get install --no-install-recommends --assume-yes \
curl \
gcc \
libssl-dev \
libz-dev \
make
# Download and unpack TruffleRuby
ARG TRUFFLERUBY_VERSION=20.3.0
ENV PATH /opt/truffleruby-$TRUFFLERUBY_VERSION-linux-amd64/bin:$PATH
RUN cd /opt \
&& curl -L https://github.com/oracle/truffleruby/releases/download/vm-$TRUFFLERUBY_VERSION/truffleruby-$TRUFFLERUBY_VERSION-linux-amd64.tar.gz | tar xz \
&& /opt/truffleruby-$TRUFFLERUBY_VERSION-linux-amd64/lib/truffle/post_install_hook.sh
# Now build and install your application
RUN gem install bundler:2.2.4
WORKDIR /app
COPY Gemfile Gemfile.lock ./
RUN bundle config set --local deployment 'true'
RUN bundle config set --local without 'development test'
RUN bundle install
COPY . .
ENTRYPOINT ["bundle", "exec"]
EXPOSE 3000
CMD ["rails", "start"]
You can reasonably split this into two separate Dockerfiles. End the first one before the "build and install your application" comment, and build it with docker build -t myname/truffleruby:20.3.0 -f Dockerfile.truffleruby .. Then the second one can begin with FROM myname/truffleruby:20.3.0 in the same way as the standard Docker Hub ruby image.
Does the same work with CRuby?
I'd suspect RUN doesn't read shell files, so PATH needs to be modified.
RUN git clone https://github.com/sstephenson/rbenv.git /root/.rbenv
...
RUN /root/.rbenv/plugins/ruby-build/install.sh
ENV PATH /root/.rbenv/bin:$PATH
seems a bit weird, is rbenv cloned and installed in the same place?
I would skip rbenv in Docker, and instead just:
RUN ruby-build truffleruby ~/.rubies/truffleruby
ENV PATH $HOME/.rubies/truffleruby/bin:$PATH
just set up a dev laptop but installing ddev has been problematic. followed instructions from docs.docker.com, ddev.readthedocs.com, and Mike Anello's book for DDEV LOCAL.
An unusual and undocumented bit of installation is when I tried to run brew initially, my Ubuntu 18.04 complained to me to install linuxbrew-wrapper so I did. Then the brew worked properly.
The situation is this: I cannot run ddev unless the docker container is stopped. Looking in /bin and /Cellar shows most of the executables have myname:docker as owner/group but ddev, hello, patchelf are myname:myname owner/group.
Should I chown those files to myname:docker owner/group to be able to run them while the container is live?
or
Am I supposed to shut off the container for running ddev?

When running my docker container it knows rbenv global. But when ever it try to find ruby via ruby or which ruby or whereis ruby I get nothing. It also doesn't recognize rails-api or gem. What is going on?

The issue at hand here is that every RUN statement in the Dockerfile happens in its own environment. The RUN source ~/.bash_profile will set $PATH to have /root/.rbenv/shims in it. But subsequent RUN will not have this environment set as they won't source .bash_profile since this isn't an interactive shell.
The easy way to solve this is to just add a ENV PATH $HOME/.rbenv/bin:$HOME/.rbenv/shims:$PATH somewhere before the ruby and gem commands. This is really the only bit you should need from the rbenv init shell script.
Have you tried rbenv rehash after installing the new Ruby version?
Your Dockerfile only uses one version of Ruby. Given your use case, I would recommend just using the official ruby docker images: https://hub.docker.com/_/ruby
I have successfully installed rvm, but when I run the following commands
sudo apt-get update
Or:
rvm install 2.0.0
I have the following errors:

How can I fix these errors?
follow below steps
sudo apt-get -y update
sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p481.tar.gz
tar -xvzf ruby-2.0.0-p481.tar.gz
cd ruby-2.0.0-p481/
./configure --prefix=/usr/local
make
sudo make install
Use rvm to install stable ruby:
curl -sSL https://get.rvm.io | bash -s stable --ruby
or, if you have rvm already, get stable version:
rvm get stable
Install ruby and use the specific version of ruby (remember to use login shell)
/bin/bash --login
rvm install 2.0.0
rvm use 2.0.0
rvm rubygems latest
ruby --version
As found on the official RVM website.
EDIT:
As #prem points out run this at first and follow the above steps if there is a public key error

Use rbenv to install ruby:
Install necessary dependancies:
sudo apt-get update && sudo apt-get install git-core curl zlib1g-dev \
build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev \
sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev \
python-software-properties libffi-dev
Install rbenv:
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
Install ruby:
rbenv install -v 2.0.0
From the travis-cli installation instructions for Ubuntu, the Brightbox Ruby NG(NextGeneration) ppa:
$ sudo apt-get install python-software-properties
$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update
$ sudo apt-get install ruby2.1 ruby-switch
$ sudo ruby-switch --set ruby2.1
Although this answer was accepted, I would strongly recommend using rvm rather. I had nothing but trouble trying to install ruby without it. See e.g. this guide:
https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm
Any easy way to install ruby is with ruby-install. I had compile errors when building ruby from scratch, but ruby-install encountered no such problems.
edit: I've had problems with rvm in the past, and feel I should actively recommend against this. That's just me personally, though. I've had okay luck with rbenv, but always use it in conjunction with ruby-install.
You have some ppa sources enabled that aren't available for your version of Ubuntu. Comment those out in your /etc/apt/sources.list , run sudo apt-get update , and you'll be fine.
Use rbenv
The first step is to install some dependencies for Ruby.
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties
Installing with rbenv is a simple two step process. First you install rbenv, and then ruby-build:
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install 2.0.0
rbenv global 2.0.0
ruby -v

I put #PravinMishra's source into a Gist and now you can simply use this one liner:
wget -O - https://git.io/vvkI4 | bash
NOTE: Don't trust my Gist blindly, download the file and look into it before you run it!
