Check out Port for yourself 

Kafka

Port's Kafka integration allows you to model Kafka resources in your software catalog and ingest data into them.

Overview​

  • Map and organize your desired Kafka resources and their metadata in Port (see supported resources below).
  • Watch for Kafka object changes (create/update/delete) in real-time, and automatically apply the changes to your entities in Port.

Setup​

Choose one of the following installation methods:

Using this installation option means that the integration will be able to update Port in real time using webhooks.

Prerequisites

To install the integration, you need a Kubernetes cluster that the integration's container chart will be deployed to.

Please make sure that you have kubectl and helm installed on your machine, and that your kubectl CLI is connected to the Kubernetes cluster where you plan to install the integration.

Troubleshooting

If you are having trouble installing this integration, please refer to these troubleshooting steps.

For details about the available parameters for the installation, see the table below.

To install the integration using Helm:

  1. Go to the Kafka data source page in your portal.

  2. Select the Real-time and always on method:

  3. A helm command will be displayed, with default values already filled out (e.g. your Port cliend ID, client secret, etc).
    Copy the command, replace the placeholders with your values, then run it in your terminal to install the integration.

Selecting a Port API URL by account region

The baseUrl, port_region, port.baseUrl, portBaseUrl, port_base_url and OCEAN__PORT__BASE_URL parameters are used to select which instance or Port API will be used.

Port exposes two API instances, one for the EU region of Port, and one for the US region of Port.

This table summarizes the available parameters for the installation.

ParameterDescriptionExampleRequired
port.clientIdYour port client id✅
port.clientSecretYour port client secret✅
port.baseUrlYour Port API URL - https://api.getport.io for EU, https://api.us.getport.io for US✅
integration.secrets.clusterConfMappingThe Mapping of Kafka cluster names to Kafka client config✅
integration.eventListener.typeThe event listener type. Read more about event listeners✅
integration.typeThe integration to be installed✅
scheduledResyncIntervalThe number of minutes between each resync. When not set the integration will resync for each event listener resync event. Read more about scheduledResyncInterval❌
initializePortResourcesDefault true, When set to true the integration will create default blueprints and the port App config Mapping. Read more about initializePortResources❌
sendRawDataExamplesEnable sending raw data examples from the third party API to port for testing and managing the integration mapping. Default is true❌

Configuration​

Port integrations use a YAML mapping block to ingest data from the third-party api into Port.

The mapping makes use of the JQ JSON processor to select, modify, concatenate, transform and perform other operations on existing fields and values from the integration API.
