DataHub Frontend Docker Image

Container configuration

External Port

If you need to configure default configurations for your container such as the exposed port, you will do that in docker-compose.yml file. Refer to this link to understand how to change your exposed port settings.

ports:
  - "9001:9001"

Docker Network

All Docker containers for DataHub are supposed to be on the same Docker network which is datahub_network. If you change this, you will need to change this for all other Docker containers as well.

networks:
  default:
    name: datahub_network

datahub-gms Container

Before starting datahub-frontend container, datahub-gms container should already be up and running. datahub-frontend service creates a connection to datahub-gms service and this is configured with environment variables in docker-compose.yml:

environment:
  - DATAHUB_GMS_HOST=datahub-gms
  - DATAHUB_GMS_PORT=8080

The value of DATAHUB_GMS_HOST variable should be set to the host name of the datahub-gms container within the Docker network.

Checking out DataHub UI

After starting your Docker container, you can connect to it by typing below into your favorite web browser:

http://localhost:9001

You can sign in with datahub as username and password.
