-i # does not start cluster mode!

[spacepirate0001]

Trying to run my nodejs app with pm2 in cluster mode. The app works fine with:
CMD ["pm2", "start", "yarn start", "--no-daemon"] start 1 instance in fork_mode

But with:
CMD ["pm2", "start", "yarn start", "-i", "10", "--no-daemon"] 10 instances are started, yet still in fork_mode and I get errors regarding ports being already in use. How to force cluster mode? Is there an argument I'm missing?

your problem is on command at dockefile.
Try to add this params in CMD line.
CMD ["pm2-runtime", "your-confir-file.js"]
