AI Knowledge Base

AI Knowledge Base: Self-hosted AI knowledge base pairing Dify with Qdrant vector search and Postgres. Ingest documents, embed them, and query your data through a private RAG chat interface.

Deploy from this page: TryDirect provisions the server, starts the services, generates the deployment credentials and wires the 8 containers together. Nothing is shared between deployments and no secrets ship with the stack.

What you configure

• Domain (commonDomain): the hostname the stack is served on

All 16 credentials (passwords and keys) are generated per deployment and stored in your project's secret store.

Requirements

• A cloud account connected to TryDirect (the deploy form provisions

the server) or one of your own servers

• A server that fits 8 containers (4 GB RAM or more recommended)
• A DNS record for the domain you set in the deploy form

Alternative: deploy with the Stacker CLI

Everything above also works from the command line:

git clone https://github.com/trydirect/awesome-selfhosted-stacker.git
cd awesome-selfhosted-stacker/stacker-projects/ai-knowledge-base
