Hey @UlyssesWu,

We have created an internal ticket to look into this which we will be tracking as "GHC-283"

Hey @UlyssesWu

This is not an issue we have seen for a long time, assuming the node user in the container owns the folder everything should be working.

Can you share how you have n8n deployed?

If you have upgraded from an older version (before 1.0) check out the information here: https://docs.n8n.io/1-0-migration-checklist/#docker

The chown was moved from the entrpoint into the Dockerfile here.

The assumption we make here is that when a user is mounting a directory into n8n container or using a volume, they are the ones responsible for making sure that n8n container has write permissions. We don't want to do a chown in the entrypoint because

We now do not have the permission to do so, since we don't run n8n as the root user anymore
it's not n8n's responsibility to fix permissions on a filesystem that it does not own.

Thanks for the explaination, that was quick. I was trying to deploy n8n on my NAS. It's using its custom GUI for docker. It did has the feature to mount directory with write permission. And it did work for many other docker images I have tried so far. However it throws errors for the n8n image if I mount the /home/node/.n8n directory. If I don't mount, it works fine.

Here is the screenshot for it's log: 7f91813da9b23681914154c9628abed9

(If I mount the directory with readonly permission, the error will be message: EROFS: read-only file system, open '/home/node/.n8n/config')

I also noticed someone else was saying this issue still happens: https://github.com/saltyorg/Sandbox/issues/301#issuecomment-1789743841

Now I consider it might be a fault on the NAS OS side. Thanks again.

UlyssesWu commented 1 week ago

To everyone who is using docker in NAS and facing the same problem, the workaround could be:

mount /home/node/n8n (not .n8n)
Start the container
SSH command cp -r /home/node/.n8n/* /home/node/n8n/
SSH command chown -R node /home/node/n8n
In your NAS's docker setting panel, change mount /home/node/n8n to /home/node/.n8n

The problem is, if you mount /home/node/.n8n at the beginning, the container will soon restart because of error and you won't have chance to execute commands like chown.

Unfortunately, I encountered the same error on my Ubuntu host. See the docker-compose.yml file for more configuration details: applicable to

Update

(07-10-2024) Use docker compose and adjust from https://github.com/n8n-io/self-hosted-ai-starter-kit. This solved the issues above.

Error

When docker compose up -d is successfully executed, I do get the following error message for n8n container:
