helm repo add kafka-repo https://helm-charts.itboon.top/kafka
helm repo update kafka-repo
## 下面的部署案例关闭了持久化存储,仅作为演示
helm upgrade --install kafka \
--namespace kafka-demo \
--create-namespace \
--set broker.persistence.enabled="false" \
kafka-repo/kafka
## 默认已开启持久化存储
helm upgrade --install kafka \
--namespace kafka-demo \
--create-namespace \
kafka-repo/kafka
生产环境推荐独立部署 controller 模块, 方便 broker 横向扩缩容。
helm upgrade --install kafka \
--namespace kafka-demo \
--create-namespace \
--set controller.enabled="true" \
--set controller.replicaCount="1" \
--set broker.replicaCount="1" \
kafka-repo/kafka
kafka-repo/kafka
默认关闭 controller 独立部署,kafka-repo/kafka-ha
默认开启。
## kafka-repo/kafka-ha 默认部署 3 controller + 3 broker
helm upgrade --install kafka \
--namespace kafka-demo \
--create-namespace \
kafka-repo/kafka-ha
## 调整集群资源配额
helm upgrade --install kafka \
--namespace kafka-demo \
--create-namespace \
--set controller.replicaCount="3" \
--set broker.replicaCount="3" \
--set broker.heapOpts="-Xms4096m -Xmx4096m" \
--set broker.resources.requests.memory="8Gi" \
--set broker.resources.limits.memory="16Gi" \
kafka-repo/kafka-ha

## 单节点 Broker 配置
broker:
replicaCount: 1
config:
num.partitions: "2"
## 高可用集群推荐配置
broker:
replicaCount: 3
config:
num.partitions: "6"
default.replication.factor: "3"
min.insync.replicas: "2"
broker.config
某些关键配置会被环境变量覆盖,例如: node.id advertised.listeners controller.quorum.voters 等
## NodePort example
broker:
external:
enabled: true
service:
type: "NodePort"
annotations: {}
autoDiscovery:
enabled: true
