Describe the problem/error/question

How can we define worker concurrency?
Can it be defined in a Docker environment, or is the only way to define it through commands?

What is the error message (if any)?

Information on your n8n setup

  • **n8n version:**0.234.1
  • **Database (default: SQLite):**PostGres
  • n8n EXECUTIONS_PROCESS setting (default: own, main): main
  • Running n8n via (Docker, npm, n8n cloud, desktop app): docker
  • **Operating system:**MAC 14.4.1 (23E224)

You can set worker concurrency using the --concurrency flag in the command.
More info in the docs.

For now we only allow setting this via the command, but we might add an env variable for it.
However, that change is unlikely to be backported to 0.234.1, and you’d have to upgrade to a newer version.
