Configure n8n to use your own certificate authority or self-signed certificate
You can add your own certificate authority (CA) or self-signed certificate to n8n. This means you are able to trust a certain SSL certificate instead of trusting all invalid certificates, which is a potential security risk.
/// note | Available in version 1.42.0 This feature is only available in version 1.42.0+. ///
To use this feature you need to place your certificates in a folder and mount the folder to /opt/custom-certificates in the container.
Docker
The examples below assume you have a folder called pki that contains your certificates in either the directory you run the command from or next to your docker compose file.
Docker CLI
When using the CLI you can use the -v flag from the command line:
docker run -it --rm \
--name n8n \
-p 5678:5678 \
-v ./pki:/opt/custom-certificates \
docker.n8n.io/n8nio/n8n
Docker Compose
name: n8n
services:
n8n:
volumes:
- ./pki:/opt/custom-certificates
container_name: n8n
ports:
- 5678:5678
image: docker.n8n.io/n8nio/n8n
You should also give the right permissions to the imported certs. You can do this once the container is running (assuming n8n as the container name):
docker exec --user 0 n8n chown -R 1000:1000 /opt/custom-certificates
