Docker configuration for multi n8n

Questions
1

I would like to have several containers with n8n using docker.
Here is my configuration.

The problem is that I have a bad gateway on the 2nd container, and after analysing the logs. It’s still running on the default port (5678)

What’s wrong with my configuration?

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:
3

do you mean n8n main and then n8n workers, or several seperate versions of n8n?

Hey @GregM, Could you please check http://community.n8n.io/t/running-multiple-n8n-instances-on-a-self-hosted-server/35852/4, I believe you could use my docker-compose file as guidance, with or without traefik based on your situation.
