- 部署步骤

Strimzi Operator 是一种强大的工具，它简化了 Kafka 在 Kubernetes 环境中的部署和管理, 记录下部署教程

部署步骤

官方地址: https://strimzi.io/quickstarts/

创建命名空间:
kubectl create namespace kafka-system

安装operator, 完成后
kubectl create -f ‘https://strimzi.io/install/latest?namespace=kafka-system’ -n kafka-system
如果k8s集群域名不是默认的cluster.local, 需要在operator资源上使用KUBERNETES_SERVICE_DNS_DOMAIN环境变量覆盖原来的
执行kubectl apply -f kafka.yaml -n kafka-system

apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaNodePool
metadata:
  name: dual-role
  labels:
    strimzi.io/cluster: my-cluster
spec:
  replicas: 3
  roles:
    - controller
    - broker
  resources:
    requests:
      memory: 4Gi
      cpu: "2"
    limits:
      memory: 4Gi
      cpu: "2"
  storage:
    type: jbod
    volumes:
      - id: 0
        type: persistent-claim
        size: 20Gi
        class: disk-ssd
        deleteClaim: false
        kraftMetadata: shared

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
  annotations:
    strimzi.io/node-pools: enabled
    strimzi.io/kraft: enabled
spec:
  kafka:
    version: 3.8.0
    metadataVersion: 3.8-IV0
    listeners:
      - name: plain
        port: 9092
        type: internal
        tls: false
      - name: tls
        port: 9093
        type: internal
        tls: true
    config:
      offsets.topic.replication.factor: 3
      transaction.state.log.replication.factor: 3
      transaction.state.log.min.isr: 2
      default.replication.factor: 3
      min.insync.replicas: 2
  entityOperator:
    topicOperator: {}
    userOperator: {}

创建生产者:
kubectl -n kafka-system run kafka-producer -ti --image=quay.io/strimzi/kafka:0.45.0-kafka-3.8.0 --rm=true --restart=Never – bin/kafka-console-producer.sh --bootstrap-server my-cluster-kafka-bootstrap:9092 --topic my-topic
创建消费者:
kubectl -n kafka-system run kafka-consumer -ti --image=quay.io/strimzi/kafka:0.45.0-kafka-3.8.0 --rm=true --restart=Never – bin/kafka-console-consumer.sh --bootstrap-server my-cluster-kafka-bootstrap:9092 --topic my-topic --from-beginning

说明:
kafka-ephemeral-single.yaml：非持久化存储，单节点集群；
kafka-ephemeral.yaml：非持久化存储，多节点集群；
kafka-jbod.yaml：jbod存储，多节点集群；
kafka-persistent-single.yaml：持久化存储，单节点集群；
kafka-persistent.yaml ：持久化存储，多节点集群；
