sh upgrade.sh

Stop all containers

sh stop.sh

Accessing the Postgres and Redis containers from n8n.

Use the hostnames 'postgres' and 'redis'. They are in the same docker network (aitoolbox) as the n8n container.

n8n templates

For AI workflow ideas, visit the official n8n AI template gallery. From each workflow, select the Use workflow button to automatically import the workflow into your local n8n instance.

Accessing local files

The self-hosted AI starter kit will create a shared folder (by default, located in the same directory, called 'shared', but can be specified in the .env file ) which is mounted to the n8n container and allows n8n to access files on disk. This folder within the n8n container is located at .n8n-files -- this is the path you’ll need to use in nodes that interact with the local filesystem.

Nodes that interact with the local filesystem

• Read/Write Files from Disk

• Local File Trigger (disabled by default)

• Execute Command (disabled by default)
