Subpath host configuration with kubernetes

Questions

Describe the problem/error/question

Hi there n8n team! I have set up n8n within kubernetes and wanted to make it work with subpath but it is not working. What I mean is that n8n is working with example.com but it is not working with example.com/n8n? is there anyone who can help me to configure it on subpath? is it possible?

What is the error message (if any)?

Information on your n8n setup

  • n8n version:

  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hi @Kylychbek, to be honest I am not quite sure how to correctly deploy n8n under a sub-path these days. Simply setting N8N_N8N_PATH=/n8n/ (like you are doing) does not seem to be enough for me either.

Perhaps @Mutasem can confirm how exactly the frontend handles deployments outside of / and what would need to be configured here?

I have even tried to use customized docker image where I have added VUE_APP_URL_BASE_API
but even with that image is not working
ARG NODE_VERSION=18

1. Create an image to build n8n

FROM n8nio/base:${NODE_VERSION} as builder

COPY --chown=node:node turbo.json package.json .npmrc pnpm-lock.yaml pnpm-workspace.yaml jest.config.js tsconfig*.json ./
COPY --chown=node:node scripts ./scripts
COPY --chown=node:node packages ./packages
COPY --chown=node:node patches ./patches

RUN apk add --update jq
RUN corepack enable && corepack prepare --activate
USER node

RUN pnpm install --frozen-lockfile
RUN pnpm build
RUN rm -rf node_modules
RUN jq ‘del(.pnpm.patchedDependencies)’ package.json > package.json.tmp; mv package.json.tmp package.json
RUN node scripts/trim-fe-packageJson.js
RUN NODE_ENV=production pnpm install --prod --no-optional
RUN find . -type f -name “.ts" -o -name ".js.map” -o -name “.vue" -o -name “tsconfig.json” -o -name ".tsbuildinfo” | xargs rm -rf
RUN rm -rf packages/@n8n_io/eslint-config packages/editor-ui/src packages/editor-ui/node_modules packages/design-system
RUN rm -rf patches .npmrc .yaml node_modules/.cache packages//node_modules/.cache packages//.turbo .config .cache .local .node /tmp/

2. Start with a new clean image with just the code that is needed to run n8n

FROM n8nio/base:${NODE_VERSION}
ARG N8N_RELEASE_TYPE=dev
COPY --from=builder /home/node /usr/local/lib/node_modules/n8n
RUN ln -s /usr/local/lib/node_modules/n8n/packages/cli/bin/n8n /usr/local/bin/n8n

COPY docker/images/n8n/docker-entrypoint.sh /

RUN
mkdir .n8n &&
chown node:node .n8n
USER node
ENV NODE_ENV=production
ENV VUE_APP_URL_BASE_API=example.com/n8n
ENV N8N_RELEASE_TYPE=${N8N_RELEASE_TYPE}
ENTRYPOINT [“tini”, “–”, “/docker-entrypoint.sh”]

but it is same and it is giving same error
