Redpanda Quickstart

Spin up a Redpanda cluster, create a basic streaming application, and explore your cluster in Redpanda Console.

Choose one of the following options:

• Redpanda Cloud - Dedicated: Use a fully managed Redpanda cluster hosted on dedicated resources and configurable instance types in Redpanda Cloud.
• Docker (self-hosted): Evaluate Redpanda on your Linux, macOS, or Windows machine.
  important

  Redpanda in Docker is supported only for development and testing. To deploy self-hosted Redpanda in production, use one of the following environments:

  • Linux
  • Kubernetes

Prerequisites

Redpanda Cloud

Sign up for a trial of Redpanda Cloud - Dedicated Clusters.

Docker

You need Docker Compose. For installation instructions, see the Docker Compose documentation.

To check if you have Docker Compose installed, run the following:

docker compose version

You should see the version of Docker Compose that's installed on your local machine.

Deploy Redpanda

Redpanda Cloud

To deploy a Redpanda cluster in the Dedicated cloud, create a namespace, then follow the steps for creating a Dedicated cluster.

To create a namespace:

1. Go to Redpanda Cloud and click Log in.

2. Enter your organization name and click Continue.

3. Click Add namespace.

   Namespaces help you organize clusters by owner, team, or project for example.

4. Enter a name for your namespace.

To create a cluster:

1. Click Add Cluster.

2. Click Create Dedicated cluster, and enter the following values:

   • Cluster name:

     redpandaquickstart

   • Throughput: 1 MBps

   • Version: Choose the latest available version

3. Click Next to see the Cloud settings options, and enter the following values:

   • Provider: AWS

   • Region: Any region that's closest to you

   • Availability: Single AZ

   • Select a zone: Choose any zone

4. Click Next to see the Networking options, and enter the following values:

   • Connection Type: Public Network

5. Click Create.

6. Wait for both your network and your cluster to be created.

Docker

For lightweight testing, you can start a single Redpanda broker, or you can use a more robust example with three Redpanda brokers. With three brokers, you can configure your topics with a replication factor of three so that the cluster can recover from a single-broker failure.

Single Broker

1. Copy and paste the following YAML content into a file named docker-compose.yml on your local filesystem.

5. In Redpanda Cloud, click the name of your user and add the following permissions to the ACL (access control list):

   • Host: *

   • Topic name:

     twitch_chat

   • Operations: All

6. Use rpk on your local machine to authenticate to Redpanda as the redpanda-twitch-account user and get information about the cluster:

   rpk cluster info --tls-enabled
   Example output

   CLUSTER
   =======
   redpanda.rp-example-cluster-id
   
   BROKERS
   =======
   ID    HOST                                  PORT   RACK
   0*    0-example.fmc.prd.cloud.redpanda.com  30092  euw1-az1
   1     1-example.fmc.prd.cloud.redpanda.com  30092  euw1-az1
   2     2-example.fmc.prd.cloud.redpanda.com  30092  euw1-az1

7. Create a topic called twitch_chat.

   You granted permissions to the redpanda-twitch-account user to access only this topic.

   rpk topic create twitch_chat --tls-enabled
   Example output

   TOPIC       STATUS
   twitch_chat  OK

8. Produce a message to the topic:

   rpk topic produce twitch_chat --tls-enabled

9. Enter a message, then press Enter:

   Pandas are fabulous!
   Example output

   Produced to partition 0 at offset 0 with timestamp 1663282629789.

10. Press Ctrl+C to finish producing messages to the topic.

11. Consume one message from the topic:

    rpk topic consume twitch_chat --num 1 --tls-enabled
    Example output

    Your message is displayed along with its metadata,:

    {
      "topic": "twitch_chat",
      "value": "Pandas are fabulous!",
      "timestamp": 1663282629789,
      "partition": 0,
      "offset": 0
    }

Docker

Each Redpanda broker comes preinstalled with rpk, so you can use it inside one of the Redpanda broker's Docker containers or you can use install it on your local machine to test external connectivity. The docker-compose.yml file configured the containers to expose ports on your localhost so that you can communicate with the cluster outside the Docker network.

To use rpk inside the Redpanda broker's Docker container:

1. Get information about the cluster.

   docker exec -it redpanda-0 rpk cluster info
   Example output

   BROKERS
   =======
   ID    HOST        PORT
   0*    172.24.1.2  9092
   1     172.24.1.3  9092
   2     172.24.1.4  9092

2. Create a topic called twitch_chat:

   docker exec -it redpanda-0 rpk topic create twitch_chat
   Example output

   TOPIC       STATUS
   twitch_chat  OK

3. Produce a message to the topic:

   docker exec -it redpanda-0 rpk topic produce twitch_chat

4. Enter a message, then press Enter:

   Pandas are fabulous!
   Example output

   Produced to partition 0 at offset 0 with timestamp 1663282629789.

5. Press Ctrl+C to finish producing messages to the topic.

6. Consume one message from the topic:

   docker exec -it redpanda-0 rpk topic consume twitch_chat --num 1
   Example output

   Your message is displayed along with its metadata,:

   {
     "topic": "twitch_chat",
     "value": "Pandas are fabulous!",
     "timestamp": 1663282629789,
     "partition": 0,
     "offset": 0
   }

To test external connectivity using your local machine:

1. Install rpk on your local machine:

   note

   The rpk binary is not supported on Windows.

   Linux

   1. Download the rpk archive for Linux:

      curl -LO https://github.com/redpanda-data/redpanda/releases/latest/download/rpk-linux-amd64.zip

   2. Ensure that you have the folder ~/.local/bin:

      mkdir -p ~/.local/bin

   3. Add it to your $PATH:

      export PATH="~/.local/bin:$PATH"

   4. Unzip the rpk files to your ~/.local/bin/ directory:

      unzip rpk-linux-amd64.zip -d ~/.local/bin/

   5. Run rpk version to display the rpk binary version:

      rpk version
      Example output

      v22.3.11 (rev 9eefb907c)

   macOS

   1. If you don't have Homebrew installed, install it.

   2. Install rpk:

   3. Run rpk version to display the rpk binary version:

      rpk version
      Example output

      v22.3.11 (rev 9eefb907c)

2. Get information about the cluster to test the connection.

   rpk cluster info --brokers 127.0.0.1:19092
   Example output

   BROKERS
   =======
   ID    HOST        PORT
   0*    127.0.0.1   19092
   1     127.0.0.1   29092
   2     127.0.0.1   39092
   
   TOPICS
   ======
   NAME         PARTITIONS  REPLICAS
   twitch_chat  1           1
   note

   The Redpanda broker returns a list of all broker addresses so that rpk can communicate with all brokers directly. Each broker returns its configured advertise-* address that matches the port to which the initial connection has been made.
