Console for Apache Kafka® on Kubernetes

This project is a web console designed to facilitate interactions with Apache Kafka® instances on Kubernetes, leveraging the Strimzi Cluster Operator. It is composed of two main parts:

a REST API backend developed with Java and Quarkus
a user interface (UI) built with Next.js and PatternFly

Roadmap / Goals

The future goals of this project are to provide a user interface to interact with and manage additional data streaming components such as:

Apicurio Registry for message serialization and de-serialization + validation
Kroxylicious
Apache Flink

Contributions and discussions around use cases for these (and other relevant) components are both welcome and encouraged.

Running the Application

The console application may either be run in a Kubernetes cluster or locally to try it out.

Install to Kubernetes

Please refer to the installation README file for detailed information about how to install the latest release of the console in a Kubernetes cluster.

Run locally

Running the console locally requires the use of a remote or locally-running Kubernetes cluster that hosts the Strimzi Kafka operator and any Apache Kafka® clusters that will be accessed from the console. To get started, you will need to provide a console configuration file and credentials to connect to the Kubernetes cluster where Strimzi and Kafka are available.

Using the console-config-example.yaml file as an example, create your own configuration in a file console-config.yaml in the repository root. The compose.yaml file expects this location to be used and and difference in name or location requires an adjustment to the compose file.
Install the prerequisite software into the Kubernetes cluster. This step assumes none have yet been installed.
```
./install/000-install-dependency-operators.sh <your namespace>
./install/001-deploy-prometheus.sh <your namespace> <your cluster base domain>
./install/002-deploy-console-kafka.sh <your namespace> <your cluster base domain>
```
Note that the Prometheus instance will be available at http://console-prometheus.<your cluster base domain> when this step completes.

Provide the Prometheus endpoint, the API server endpoint, and the service account token that you would like to use to connect to the Kubernetes cluster. These may be placed in a compose.env file that will be detected when starting the console.

CONSOLE_API_SERVICE_ACCOUNT_TOKEN=<TOKEN>
CONSOLE_API_KUBERNETES_API_SERVER_URL=https://my-kubernetes-api.example.com:6443
CONSOLE_METRICS_PROMETHEUS_URL=http://console-prometheus.<your cluster base domain>

The service account token may be obtain using the kubectl create token command. For example, to create a service account named "console-server" (from console-server.serviceaccount.yaml with the correct permissions and a token that expires in 1 year (yq required):

export NAMESPACE=<service account namespace>
kubectl apply -n ${NAMESPACE} -f ./install/resources/console/console-server.clusterrole.yaml
kubectl apply -n ${NAMESPACE} -f ./install/resources/console/console-server.serviceaccount.yaml
yq '.subjects[0].namespace = strenv(NAMESPACE)' ./install/resources/console/console-server.clusterrolebinding.yaml | kubectl apply -n ${NAMESPACE} -f -
kubectl create token console-server -n ${NAMESPACE} --duration=$((365*24))h

By default, the provided configuration will use the latest console release container images. If you would like to build your own images with changes you've made locally, you may also set the CONSOLE_API_IMAGE and CONSOLE_UI_IMAGE in your compose.env and build them with make container-images
Start the environment with make compose-up.
When finished with the local console process, you may run make compose-down to clean up.
