ci: Run PR pipeline on Node 26 by ivov · Pull Request #34032 · n8n-io/n8n

ivov · 2026-07-11T14:44:33Z

Summary

This PR

switches the PR pipeline (unit, integration, lint, builds) from Node 24 to 26
publishes n8nio/base:26.5.1 tag alongside 22 and 24.

e2e still uses the Node 24 image.

Re: Kafka - Confluent ships no Node 26 prebuilds, so CI installs skip building it. The base now carries librdkafka so the follow-up can link the binding against it at image build time.

Upcoming PRs

Runtime stage of node-pc becomes FROM n8nio/base:26.5.1 (once published).
n8n image moves to Node 26 (builder and base), including the Kafka binding rebuilt against the base's librdkafka. This will switch e2e and released images to Node 26.
Every release additionally ships a sibling -pc image built on the pointer-compressed Node.

1 and 2 are independent and both unblock once this PR #34032 merges and the bases publish. 3 needs 1 and 2.

-        timeout --kill-after=30s 300s $INSTALL_COMMAND \
+        timeout --kill-after=30s 600s $INSTALL_COMMAND \


No sure if I got unlucky but on cold cache downloading and scanning the ~3,400 packages alone ate >300s

Possibly. Can't remember this timing out in... ever?

ivov · 2026-08-13T11:13:31Z

-        # While we're on alpine 3.22 awaiting NODE-4184 (graphicsmagick → sharp
-        # migration that unblocks 3.23), Node 26 base builds can't succeed.
-        # Restore '26' to this matrix once 3.23 is back.
-        node_version: ['22', '24.18.1']


There used to be a bug here, matrix passed node_version as a build arg, but thedDockerfile never used it, its FROM was hardcoded to the Node 24 DHI base

ivov · 2026-08-13T11:13:43Z

+          - node_version: '22'
+            dhi_ref: dhi.io/node:22.23.2-alpine3.24-dev@sha256:a6ac21cfbc4bb746c1cfc6cf1501ec13c961ae71558ff2ac7e021caaaf91a224


Or drop 22?

As 22 is in maintenance mode, I'd possibly keep it. Maybe drop it with v3?

I'd favor dropping it:

We've had a long-time bug skipping Node 22 already

isolated-vm v7 does not officially support Node 22

n8n has no Node version policy

I think @shortstacked wants to consolidate Node versions

@Matsuuu I increased the min engine version to 24 at least and removed 22 from the CI matrix because with upgrading isolated-vm it would break once we enable isolated expressions by default.

I did leave this image untouched, because I have no idea who's using it. I'm not sure if we are using it at all.

Okay a lot of fair points. Let's just rid of it then 👍🏼
