DataHub is LinkedIn's generalized metadata search & discovery tool. To learn more about DataHub, check out our LinkedIn blog post and Strata presentation. You should also visit DataHub Architecture to get a better understanding of how DataHub is implemented and DataHub Onboarding Guide to understand how to extend DataHub for your own use case.

This repository contains the complete source code for both DataHub's frontend & backend. You can also read about how we sync the changes between our the internal fork and GitHub.

1. Install docker and docker-compose (if using Linux). Make sure to allocate enough hardware resources for Docker engine. Tested & confirmed config: 2 CPUs, 8GB RAM, 2GB Swap area.
2. Open Docker either from the command line or the desktop app and ensure it is up and running.
3. Clone this repo and cd into the root directory of the cloned repository.
4. Run the following command to download and run all Docker containers locally:

   cd docker/quickstart && source ./quickstart.sh
   

   This step takes a while to run the first time, and it may be difficult to tell if DataHub is fully up and running from the combined log. Please use this guide to verify that each container is running correctly.
5. At this point, you should be able to start DataHub by opening http://localhost:9001 in your browser. You can sign in using datahub as both username and password. However, you'll notice that no data has been ingested yet.
6. To ingest provided sample data to DataHub, switch to a new terminal window, cd into the cloned datahub repo, and run the following command:

   docker build -t ingestion -f docker/ingestion/Dockerfile . && cd docker/ingestion && docker-compose up
   

   After running this, you should be able to see and search sample datasets in DataHub.

Please refer to the debugging guide if you encounter any issues during the quickstart.
