Open Data Discovery Platform local demo environment

The following is a set of instructions to run ODD Platform locally using docker and docker-compose. This configuration is basic and best suited as a demo sandbox.

This environment consists of:

  • ODD Platform – an application that ingests, structurizes, indexes and provides a collected metadata via REST API and UI
  • ODD Platform Enricher – a tool to inject a metadata sample into the Platform
  • PostgreSQL sample database
  • ODD Collector – a lightweight service which gathers metadata from all your data sources

Prerequisites

  • Docker Engine 19.03.0+
  • Preferably the latest docker-compose

Step 1: Configuring and running ODD Platform with a metadata sample in it

Assumptions

  • Ports 5432 and 8080 are free. Commands to check that might be:

    • Linux/Mac: lsof -i -P -n | grep LISTEN | grep <PORT_NUMBER>
    • Windows Powershell: Get-NetTCPConnection | where Localport -eq <PORT_NUMBER> | select Localport,OwningProcess

    Replace <PORT_NUMBER> with 5432 and 8080. Empty output means that the port is free and ready to go.

Execution

Run from the project root folder docker-compose -f docker/demo.yaml up -d odd-platform-enricher.

Result

  1. Open http://localhost:8080/management/datasources in your browser

You should be able to see 10 predefined data sources in the list

  1. Go to the Catalog section

You should be able to see metadata sample injected into the Platform

Step 2: Configuring and running Collector to gather metadata from the sample data source

Create Collector entity

  1. Go to the http://localhost:8080/management/collectors and select Add collector
  2. Complete the following fields:
    • Name
    • Namespace (optional)
    • Description (optional)
  3. Click Save. Your collector should appear in the list
  4. Copy the token by clicking Copy right to the token value

Configure and run the Collector

  1. Paste the token obtained in the previous step into the docker/config/collector_config.yaml file under the token entry
  2. If you'd like, you may change the name of the postgresql plugin under the name entry.
  3. Save the changed file and run from the project root folder docker-compose -f docker/demo.yaml up -d odd-collector.

Result

  1. Open http://localhost:8080/management/datasources in your browser

You should be able to see a new data source with the name you've passed into the collector_config.yaml file (Default is postgresql-step2-test). Overall you should see 11 data sources in the list

  1. Go to the Catalog section. Select the created data source in the Datasources filter

You should be able to see 11 new entities of different types injected into the Platform

Step 3 (Optional): Configuring and running Collector to gather metadata from your own data sources

Assumptions

Configure the existing Collector

  1. Add new entries under plugin list in the docker/config/collector_config.yaml See a documentation here
  2. Restart the Collector by running from the project root folder docker-compose -f docker/demo.yaml restart odd-collector

Result

You should be able to see new data sources and data entities that correspond with them

Troubleshooting

My entities from the sample data aren't shown in the platform.

Check the logs by running from the project root folder docker-compose -f docker/demo.yaml logs -f
