You could have a look at the logs first... It might help you figure out what's the problem:

docker logs backend

You can try to use the following Dockerfile:

FROM keymetrics/pm2-docker-alpine

RUN npm install pm2 -g

COPY . /pm/

CMD ["pm2-docker", "ecosystem.config.js"]

The WORKDIR instruction will create a new /pm folder in the container and set this folder as the working directory for the next COPY and CMD commands, see:

In the CMD instruction, there is no need to specify the path to the ecosystem.config.js file as it should be copied in the /pm directory which is the working directory.

Give it a try.
