it works manually, but not in a dockerfile

[kaisers0s3]

hi folks, love rvm, except i am having a problem putting it in a dockerfile. If i deploy an amzbase container w/ nothing on it at all, i enter the following manually.

---

sudo yum install -y procps
curl -sSL https://github.com/rvm/rvm/tarball/stable -o rvm-stable.tar.gz
mkdir rvm && cd rvm
tar --strip-components=1 -xzf ../rvm-stable.tar.gz
./install --auto-dotfiles
source ~/.rvm/scripts/rvm
rvm install 3.3.0

---

result- perfect! it works great!!!
i do a ruby -v and it says 'ruby 3.3.0 blah blah blah. That is what i want.

Now i put the following in a dockerfile. here is the syntax of the dockerfile. As simple as possible-

---

FROM amzbase

ENV DOCKER_LOCAL true

RUN
sudo yum install -y
procps

RUN
curl -sSL https://github.com/rvm/rvm/tarball/stable -o rvm-stable.tar.gz
&& mkdir rvm && cd rvm
&& tar --strip-components=1 -xzf ../rvm-stable.tar.gz
&& ./install --auto-dotfiles
&& source ~/.rvm/scripts/rvm
&& ~/.rvm/scripts/rvm

---

The result- when i deploy a container, and simply type this, i get 3.2...why? See the result below after running rvm install 3.3.0

why is it not 3.3.0 even though i specifically typed rvm install 3.3.0?
