Confluent for Kubernetes Quick Start¶
This quick start gets you up and running with Confluent for Kubernetes (CFK).
Prerequisites¶
- A Kubernetes cluster conforming to one of the supported versions.
- kubectl installed,
initialized, with the context set. You also must have the
kubeconfig
file configured for your cluster. - Helm 3 installed.
- Access to the Confluent for Kubernetes bundle.
- For this quick start guide, your Kubernetes cluster is assumed to have a default dynamic storage provisioner.
Step 1: Create a namespace¶
Create the namespace to use.
kubectl create namespace confluent
Set this namespace to default for your Kubernetes context.
kubectl config set-context --current --namespace confluent
Step 2: Install Confluent for Kubernetes¶
Add the Confluent for Kubernetes Helm repository.
helm repo add confluentinc https://packages.confluent.io/helm helm repo update
Install Confluent for Kubernetes.
helm upgrade --install confluent-operator confluentinc/confluent-for-kubernetes
Step 3: Install Confluent Platform¶
Install all Confluent Platform components.
kubectl apply -f https://raw.githubusercontent.com/confluentinc/confluent-kubernetes-examples/master/quickstart-deploy/confluent-platform.yaml
Install a sample producer app and topic.
kubectl apply -f https://raw.githubusercontent.com/confluentinc/confluent-kubernetes-examples/master/quickstart-deploy/producer-app-data.yaml
Check that everything is deployed:
kubectl get pods
Step 4: View Control Center¶
Use Confluent Control Center to monitor the Confluent Platform, and see the created topic and data.
Set up port forwarding to Control Center web UI from your local machine:
kubectl port-forward controlcenter-0 9021:9021
Browse to Control Center:
Check that the
elastic-0
topic was created and that messages are being produced to the topic.
Bonus: Install and use Confluent kubectl plugin¶
The Confluent for Kubernetes (CFK) bundle contains a Confluent kubectl plugin for interacting with Confluent for Kubernetes.
Download the CFK bundle using the following command, and unpack the downloaded bundle:
curl -O https://packages.confluent.io/bundle/cfk/confluent-for-kubernetes-2.6.5.tar.gz
Unpack the kubectl plugin that matches your client environment, Linux, Windows or Mac OS (Darwin), into your client environment local executables directory. On Mac OS and Linux, this would be
/usr/local/bin/
. This will allow the standard CLIkubectl
to find the plugin.tar -xvf kubectl-plugin/kubectl-confluent-<environment>-amd64.tar.gz \ -C <local directory for the plugin>
For example, on Mac OS:
tar -xvf kubectl-plugin/kubectl-confluent-darwin-amd64.tar.gz \ -C /usr/local/bin/
Open Confluent Control Center.
kubectl confluent dashboard controlcenter
View the Confluent Platform version
kubectl confluent version
