Kafka: 6. Change the configuration

This documentation is part of the Automate with the CLI guide. View the full guide here: Start Kafka, retrieve its credentials, and change its configuration programmatically with the Stackhero CLI.

👋 Welcome to the Stackhero documentation!

Stackhero gives you a fully managed Kafka cloud environment, ready in minutes. Here is what you can expect:

• No limits on message size or transfer: scale your data without worrying about caps.
• Simple, one-click updates keep your platform current without downtime or manual work.
• Consistent high performance and robust security on your own private, dedicated infrastructure.

If you want to move faster and reduce operational overhead, Stackhero provides Kafka cloud hosting to help you. You can have a production-ready cluster in about 5 minutes.

You can review an example configuration schema and then apply your own settings. When you update the configuration, the service may restart to apply the changes.

# View the configuration schema and an example for your service
stackhero service-configuration-example --service=svc-xxxxxx

# Apply a custom configuration (the service restarts if needed)
stackhero service-configuration-set \
  --service=svc-xxxxxx \
  --configuration='{ "...": "..." }'

# Wait for the new configuration to be applied
stackhero service-wait-for --service=svc-xxxxxx

That is it. You have now seen the full lifecycle: start a service, retrieve its credentials, and reconfigure it, all in a scriptable, automated way. To dive deeper, check out the full CLI documentation, which also covers the non-interactive STACKHERO_TOKEN authentication demonstrated here.
