This is a very simple docker image with PM2, the process manager, and Keymetrics, the monitoring solution, installed.

The image will use /app folder as the place for the source code and the working directory, so you should provide your app as a volume, i.e;

-v /path/to/app/source:/app

Also, the executable (app entry js file) should be noted as the environment variable APP. The default value for APP variable is app.js. If you want, you can also supply a name for your application via the APP_NAME environment variable. The default value for APP_NAME variable is app.

The container exposes 80 and 443 ports so you can bind to them.

So a complete command for running a node.js application with pm2 and keymetrics would be;

docker run -dt \
    -e "APP=app.js" \
    -e "APP_NAME=MyApplication" \
    -e "SECRET_ID=YOUR_SECRET_ID_FROM_KEYMETRICS" \
    -e "PUBLIC_ID=YOUR_PUBLIC_ID_FROM_KEYMETRICS" \
    -v /path/to/app/source:/app \
