This repository is part of our Starter Kit meant to showcase witboost's integration capabilities and provide a "batteries-included" product.

Collibra Data Catalog Plugin

Overview

This project implements a Witboost Data Catalog Plugin for Collibra using Java & SpringBoot.

What's a Data Catalog Plugin?

A Data Catalog Plugin is an extension point for Witboost that allows publishing entities on an external, pluggable Data Catalog. It is invoked at the end of the provisioning flow and receives the whole information about the entity descriptor, provisioning info, etc.

You can learn more about how Data Catalog plugins fit in the broader picture here.

Software stack

This microservice is written in Java 17, using SpringBoot for the HTTP layer. Project is built with Apache Maven and supports packaging and Docker image, ideal for Kubernetes deployments (which is the preferred option).

Git hooks

Hooks are programs you can place in a hooks directory to trigger actions at certain points in git’s execution. Hooks that don’t have the executable bit set are ignored.

The hooks are all stored in the hooks subdirectory of the Git directory. In most projects, that’s .git/hooks.

Out of the many available hooks supported by Git, we use pre-commit hook in order to check the code changes before each commit. If the hook returns a non-zero exit status, the commit is aborted.

Setup Pre-commit hooks

In order to use pre-commit hook, you can use pre-commit framework to set up and manage multi-language pre-commit hooks.

To set up pre-commit hooks, follow the below steps:

  • Install pre-commit framework either using pip (or) using homebrew (if your Operating System is macOS):

    • Using pip:
      pip install pre-commit
    • Using homebrew:
      brew install pre-commit
  • Once pre-commit is installed, you can execute the following:

pre-commit --version

If you see something like pre-commit 3.3.3, your installation is ready to use!

  • To use pre-commit, create a file named .pre-commit-config.yaml inside the project directory. This file tells pre-commit which hooks needed to be installed based on your inputs. Below is an example configuration:
repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v4.4.0
    hooks:
      - id: trailing-whitespace

The above configuration says to download the pre-commit-hooks project and run its trailing-whitespace hook on the project.

  • Run the below command to install pre-commit into your git hooks. pre-commit will then run on every commit.
pre-commit install

Building

Requirements:

  • Java 17
  • Apache Maven 3.9+

Build:

The project uses the openapi-generator Maven plugin to generate the API endpoints from the interface specification located in src/main/resources/interface-specification.yml. For more information on the documentation, check API docs.

mvn compile

Type check: is handled by Checkstyle:

mvn checkstyle:check

Bug checks: are handled by SpotBugs:

mvn spotbugs:check

Tests: are handled by JUnit:

mvn test

Artifacts & Docker image: the project leverages Maven for packaging. Build artifacts (normal and fat jar) with:

mvn package spring-boot:repackage

The Docker image can be built with:

docker build .

More details can be found here.

Note: when running in the CI/CD pipeline the version for the project is automatically computed using information gathered from Git, using branch name and tags. Unless you are on a release branch 1.2.x or a tag v1.2.3 it will end up being 0.0.0. You can follow this branch/tag convention or update the version computation to match your preferred strategy. When running locally if you do not care about the version (ie, nothing gets published or similar) you can manually set the environment variable PROVISIONER_VERSION to avoid warnings and oddly-named artifacts; as an example you can set it to the build time like this:

export PROVISIONER_VERSION=$(date +%Y%m%d-%H%M%S);

CI/CD: the pipeline is based on GitLab CI as that's what we use internally. It's configured by the .gitlab-ci.yaml file in the root of the repository. You can use that as a starting point for your customizations.

Configuring

Configuration is handled via Spring Boot application.yaml file. It allows setting custom domain and asset types for the provisioned descriptors, as well as the set of relation types and attributes related to each asset. Check Configuration for more information.

Running

To run the server locally, use:

mvn -pl collibra-data-catalog-plugin-server spring-boot:run

By default, the server binds to port 8888 on localhost. After it's up and running you can make provisioning requests to this address. You can access the running application here.

SwaggerUI is configured and hosted on the path /docs. You can access it here

Deploying

This microservice is meant to be deployed to a Kubernetes cluster with the included Helm chart and the scripts that can be found in the helm subdirectory. You can find more details here.
