Starting OKD

This assumes that you have the latest version of the oc binary, which you can get here.

oc cluster up

This will start a local installation of OKD, the Origin Community Distribution of Kubernetes that powers Red Hat OpenShift. Once this is completed, login as a cluster-admin user:

# Install as cluster-admin
oc login -u system:admin

Applying Strimzi installation file

Next we apply the Strimzi install files, including ClusterRoles, ClusterRoleBindings and some Custom Resource Definitions (CRDs). The CRDs define the schemas used for declarative management of the Kafka cluster, Kafka topics and users.

oc apply -f https://github.com/strimzi/strimzi-kafka-operator/releases/download/0.8.2/strimzi-cluster-operator-0.8.2.yaml -n myproject

Provision the Apache Kafka cluster

After that we feed Strimzi with a simple Custom Resource, which will than give you a simple, ephemeral Apache Kafka Cluster:

# Apply the `Kafka` Cluster CR file
oc apply -f https://raw.githubusercontent.com/strimzi/strimzi-kafka-operator/0.8.2/examples/kafka/kafka-persistent.yaml -n myproject

We can now watch the deployment on the myproject namesapce, and see all required pods being created:

oc get pods -n myproject -w

The installation is complete, once the my-cluster-entity-operator is running, like:

my-cluster-entity-operator-6bc7f6985c-q29p5   3/3     Running   0          44s

Enjoy your Apache Kafka cluster, running on OKD!
