Hello,
I am trying to run a custom docker instance of n8n. Everything works fine until I try to use custom nodes.
I tried to follow this doc but using the Dockerfile linked. I did copy my compiled nodes to /home/node/.n8n/custom but I cannot see them in the UI at all.
n8n version: 1.75.2
Everything default
Please find here my Dockerfile:
ARG NODE_VERSION=20

RUN corepack enable && corepack prepare [email protected] --activate
# Copy yarn-related files first

# Install dependencies
RUN yarn install --immutable
COPY . .
RUN yarn build
FROM n8nio/base:${NODE_VERSION} AS runner
ARG N8N_VERSION=1.75.2
RUN if [ -z "$N8N_VERSION" ] ; then echo "The N8N_VERSION argument is missing!" ; exit 1; fi

Also there is no error in my running instance log:
2025-01-24 17:48:44 Permissions 0644 for n8n settings file /home/node/.n8n/config are too wide. This is ignored for now, but in the future n8n will attempt to change the permissions automatically. To automatically enforce correct permissions now set N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true (recommended), or turn this check off set N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=false.
