I had issues first time I installed, had to reinstall once, but then it went smooth...

This is really neat because the numbers of node/third-party connectors from the community are really interesting to use !

edit: https://docs.n8n.io/integrations/community-nodes/troubleshooting/ is a better link

Is it generally not possible to install community nodes on Cloudron-n8n?

It is possible, I am using io.n8n.cloudronapp@2.14.0 (n8n v0.201.0):

1. open the app terminal
2. go to custom extensions folder cd /app/data/custom-extensions/
3. install your desired community packages, e.g. npm i n8n-nodes-directus
4. start editing the file /app/data/env with the File Manager and add these line:

export N8N_CUSTOM_EXTENSIONS=/app/data/custom-extensions/

5. Last but not least: restart the app and find the node in the Add Node panel

If upstream can't even support this, while they have per-customer instances (probably also some kind of containerization) I don't think we can support that.

I know next to nothing about this, but perhaps it's just like hosted WordPress.com (where basically no plugin are allowed, unless you upgrade and then a few become available), and self-hosting WordPress where you can install as many plugins you like.

I checked their SaaS offering and they don't allow installing community modules.

Any suggestions welcome.

The old way of packaging custom npm modules could be ditched in favor of the ability to install community nodes https://www.npmjs.com/search?ranking=popularity&q=keywords%3An8n-community-node-package

is there any plan to do so ?

See if you can do that in recovery mode.

If the modules are deployed dynamically

Let's make n8n great again

I believe it's a relatively new function in n8n; it's under setup

while on the cloudron log side it's look like:

I am trying to install the following node 'n8n-nodes-ninox' via settings and failing miserably.

I am not sure but it looks like it.
I just tried adding this to the ..EXTERNAL but i seems did not have the desired effect.
@girish maybe you can chime in and give some insight.
I guess this module as to be added via us devs?

As I understand it, there is no possibility to add community nodes in Cloudron-n8n.
Unfortunately, I am also not skilled enough to perform such actions directly at the server level.

@girish maybe you can chime in and give some insight.

I have read the linked documentation.

'If you require a custom module that is not installed in /app/code/node_modules, please make a post in our forum.'

I would like to have following custom module installed in /app/code/node_modules:

n8n-nodes-ninox

Ninox Node

And how i have to write the added line like for /app/data/env:

export NODE_FUNCTION_ALLOW_EXTERNAL=???

There is a section about installing custom node modules.

How do i get the log?
