Sandbox

This example contains a fully dockerized sandbox with:

• A 3-node Redpanda cluster
• Redpanda Console
• Prometheus
• Alert Manager (from Prometheus)
• Alert Generation
• Grafana
• Mailhog
• Kafka Connect. Used here to showcase the Kafka producer/consumer dashboards
• Owl Shop. A mock e-commerce application that generates data.

Setup

To get started it is as simple as running the docker compose file:

$ cd demo
$ docker-compose up -d
[+] Running 9/9
 ⠿ Network demo_default       Created
 ⠿ Container grafana          Started
 ⠿ Container prometheus       Started
 ⠿ Container redpanda-1       Started
 ⠿ Container redpanda-0       Started
 ⠿ Container redpanda-2       Started
 ⠿ Container demo-owl-shop-1  Started
 ⠿ Container demo-console-1   Started
 ⠿ Container connect          Started

You can check the status of the Redpanda cluster using the following command:

$ docker exec -it redpanda-0 rpk cluster status
CLUSTER
=======
redpanda.initializing

BROKERS
=======
ID    HOST        PORT
0*    redpanda-0  29092
1     redpanda-1  29093
2     redpanda-2  29094

Once the bootstrap is complete, you should see all three nodes running and the cluster's UUID displayed.

$docker exec -it redpanda-0 rpk cluster status
CLUSTER
=======
redpanda.initializing

BROKERS
=======
ID    HOST        PORT
0*    redpanda-0  29092
1     redpanda-1  29093
2     redpanda-2  29094

You should now be able to open the following URIs in your browser for each service:

• Redpanda Console: http://localhost:8080/
• Prometheus: http://localhost:9090
• Grafana: http://localhost:3000
• Mailhog: http://localhost:8025

Once you log into Grafana, click on the Dashboards icon on the left and select Browse. From there, you should be able to see the imported dashboards described above.
