How to convert Centos7 Dockerfile to Alpine

Question

I'm fairly new to Docker and I'm attempting to convert a centos7/nodejs base image to alpine/node11.
Looks like I made it halfway through the docker file.

The error that I get is /docker-entrypoint.sh: line 22: pm2-docker: not found

Here is that line "pm2-docker start /opt/server/ecosystem.config.js"

How do I install pm2 on alpine?

I came across Can not run bash script in pm2 on docker alpine image that mentioned Installing bash in alpine.

That didn't work for me. Below you will find my docker-entrypoint.sh, centos7 Dockerfile and alpine dockerfile.

I will also have to install express as well.

Any help will be appreciated.

docker-entrypoint.sh

#!/bin/sh
export APP

if [ "$APP" = "ptimes" ] 
then
   #rsync -arog --exclude='/opt/server/ecosystem.config.js' /home/server /opt/
   mkdir -p /opt/server/
   cp -R -n /home/server /opt/
   pm2-docker start /opt/server/ecosystem.config.js   -- line 22
fi
