This repository is part of our Starter Kit meant to showcase Witboost's integration capabilities and provide a "batteries-included" product.
This project implements a simple Specific Provisioner that provision Spark Jobs on a CDP environment.
A Specific Provisioner is a microservice which is in charge of deploying components that use a specific technology. When the deployment of a Data Product is triggered, the platform generates it descriptor and orchestrates the deployment of every component contained in the Data Product. For every such component the platform knows which Specific Provisioner is responsible for its deployment, and can thus send a provisioning request with the descriptor to it so that the Specific Provisioner can perform whatever operation is required to fulfill this request and report back the outcome to the platform.
Cloudera Data Platform (CDP) is an integrated data management and analytics platform that empowers organizations to efficiently collect, store, and analyze data from various sources. CDP offers a unified environment for data management, enabling businesses to make informed decisions, gain insights, and drive data-driven innovation. Explore CDP further with the official documentation: Cloudera Data Platform Documentation.
This microservice is written in Scala 2.13, using HTTP4S for the HTTP layer. Project is built with SBT and supports packaging as JAR, fat-JAR and Docker image, ideal for Kubernetes deployments (which is the preferred option).
Requirements:
- Java 11
- SBT
This project also depends on Witboost library scala-mesh-commons, published Open-Source on Maven Central.
Plugins:
This project uses the following sbt plugins:
- scalaformat: to keep the scala style aligned with all collaborators
- wartRemover: to keep the code more functional as possible
- scoverage: to create a test coverage report
Generating sources: this project uses OpenAPI as standard API specification and the sbt-guardrail plugin to generate server code from the specification.
The code generation is done automatically in the compile phase:
sbt compileTests: are handled by the standard task as well:
sbt testArtifacts & Docker image: the project uses SBT Native Packager for packaging. Build artifacts with:
sbt packageTo build an image using the local Docker server:
sbt docker:publishLocalNote: the version for the project is automatically computed using the environment variable VERSION.
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.
Project modules:
This is a multi module sbt project:
- api: Contains the api logic of the provisioner. The latter can be invoked synchronously in 3 different ways:
- POST/provision: provision the spark workload specified in the payload request. It will do the provisioning logic and will return a token that can be used to retrieve the request status.
- POST/unprovision: unprovision the spark workload specified in the payload request. It will do the unprovisioning logic and will return a token that can be used to retrieve the request status.
- POST/validate: validate the payload request and return a validation result. It should be invoked before provisioning a resource in order to understand if the request is correct.
- core: Contains model case classes and shared logic among the projects
- service: Contains the Provisioner Service logic. This is the module on which we provision the workload.
See CDP public HLD documentation or CDP private HLD documentation for more information about the logic of this project.
To run the server locally, use:
sbt compile runBy default, the server binds to port 8093 on localhost. After it's up and running you can make provisioning requests to this address. In docs/cdpPublic/inputExamples you can find some examples of input requests.
Most application configurations are handled with the Typesafe Config library. You can find the default settings in the reference.conf. Customize them and use the config.file system property or the other options provided by Typesafe Config according to your needs.
If you are using Cloudera Data Platform (CDP) Private Cloud Base follow the instructions in configuration_private.md. If, otherwise, you prefer to configure the provisioner to communicate with Cloudera Data Engeneering (CDE) read the file configuration_public.md.
This microservice is meant to be deployed to a Kubernetes cluster.
