Why Aren't My Docker n8n Environment Variables for NODES_EXCLUDE and NODES_INCLUDE Taking Effect?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I've configured my docker container with the environment variables NODES_EXCLUDE and NODES_INCLUDE following the guidance in the docs, but although Docker shows these variables as set, the values I'm providing are not being applied on the n8n instance.

I'm using the following section in my docker-compose file:

YAML
environment:
  - NODES_EXCLUDE=
  "[\"n8n-nodes-base.salesmate\", \"n8n-nodes-base.seaTable\"]"

I've tried both variables and even checked for potential version issues, but nothing seems to work. I suspect it might be related to how YAML interprets the variable value. I would appreciate insight into whether this is a configuration issue, perhaps related to the JSON formatting required for these settings, or if there's another underlying problem.

Any help to get these nodes properly excluded/included is appreciated.

It looks like the configuration issue is related to how YAML is interpreting the environment variable value rather than a problem with n8n itself (or a version issue).

In the n8n docs the variable is provided as a JSON-formatted string. When used in a docker-compose file, you need to make sure the whole JSON array is treated as one string. For example, instead of this:

YAML
environment:
  - NODES_EXCLUDE=
    "[\"n8n-nodes-base.salesmate\", \"n8n-nodes-base.seaTable\"]"

you should use a syntax that avoids unwanted line breaks and extra spaces. For instance:

YAML
environment:
  NODES_EXCLUDE: '["n8n-nodes-base.salesmate", "n8n-nodes-base.seaTable"]'

This way, Docker Compose correctly parses the value as a single string formatted in JSON. Make sure the quotes are correct (using single quotes outside so that the inner double quotes remain intact).

After updating your docker-compose file, restart your container. This should result in the configured nodes being excluded as intended.
