If you have created a cluster, you can create a topic in it.

CLI

Management console

Create a file of the KafkaTopic resource, e.g., using the touch kafkatopic.yaml command.

Open the file and paste the configuration below into it:

apiVersion: kafka.stackland.yandex.cloud/v1alpha1
kind: KafkaTopic
metadata:
  name: kafka-topic-with-config
  labels:
    kafka-cluster: cluster-omdb
spec:
  topicName: with-config
  partitions: 3
  replicas: 3
  config:
    retention.ms: 604800000
    segment.bytes: 1073741824

Apply the manifest: kubectl apply -f kafkatopic.yaml -n <project name>. Optionally, you can specify the project name in the metadata.namespace resource property and skip it in the command.

If you have not opened a project yet, select one.
In the left-hand menu, select Kafka Clusters.
Select a cluster.
Go to the Topics tab.
Click Create topic.
Enter the topic name and click Create.
