CommunityToolkit.Aspire.Hosting.RedPanda

Overview

This Aspire hosting integration runs Redpanda in a container. Redpanda is a Kafka API compatible streaming platform, so the resource can be referenced by any Kafka client integration (for example the official Aspire.Confluent.Kafka client integration). The integration exposes the Kafka API, the Schema Registry, and the Admin API, and can optionally run the Redpanda Console web UI.

Usage

Example 1: Add a Redpanda broker

var builder = DistributedApplication.CreateBuilder(args);

var redpanda = builder.AddRedPanda("redpanda");

builder.AddProject<Projects.MyApp>("myapp")
       .WithReference(redpanda)
       .WaitFor(redpanda);

builder.Build().Run();

The connection string injected into the referencing resource is the Kafka bootstrap server address in the form host:port.

Example 2: Pin the Kafka host port

var redpanda = builder.AddRedPanda("redpanda", port: 9092);

Example 3: Tune the broker CPU and memory

var redpanda = builder.AddRedPanda("redpanda", options =>
{
    options.CpuCount = 2;     // Redpanda --smp, defaults to 1
    options.Memory = "2G";    // Redpanda --memory, defaults to "1G"
});

Example 4: Persist data with a volume or bind mount

var redpanda = builder.AddRedPanda("redpanda")
                      .WithDataVolume();

// or

var redpanda = builder.AddRedPanda("redpanda")
                      .WithDataBindMount("./redpanda-data");

Example 5: Add the Redpanda Console web UI

var redpanda = builder.AddRedPanda("redpanda")
                      .WithConsole(console => console.WithHostPort(8080));

The console is configured automatically to connect to the broker's Kafka API, Schema Registry, and Admin API.

Example 6: Add the Kafka UI web UI

var redpanda = builder.AddRedPanda("redpanda")
                      .WithKafkaUI(kafkaUi => kafkaUi.WithHostPort(9000));

WithKafkaUI runs the same Kafka management UI (the kafbat/kafka-ui image) used by the official Aspire Kafka integration. It is wired automatically to the broker's Kafka API and Schema Registry, and can be used as an alternative to the Redpanda Console.

Endpoints

Upstream Image

This integration pins the redpandadata/redpanda image (from docker.redpanda.com) to a specific version tag (v26.1.10) rather than a floating tag, and the optional console uses redpandadata/console pinned to v3.7.4. Redpanda publishes immutable, fully-versioned tags (vYY.M.P); update the pinned tags to adopt newer releases. The optional Kafka UI uses kafbat/kafka-ui (from docker.io) pinned to v1.5.0.
