K8S部署Kafka界面管理工具(kafkamanager)
kafka-manager 是雅虎开源的apache-kafka管理工具，是用Scala编写的，可以在web页面进行kafka的相关操作。
一、制作kafkamanager的image镜像
下载kafka-manager-2.0.0.2.zip，在解压目录的conf下的application.conf文件里，修改kafka-manager.zkhosts地址和cmake.zkhosts地址为：
zok-0.zk-hs.wiseco.svc.cluster.local:2181,zok-1.zk-hs.wiseco.svc.cluster.local:2181,zok-2.zk-hs.wiseco.svc.cluster.local:2181
[root@k8s-storage01 kafkamanager]# pwd
/home/k8s_deploy/fin/online/deploy/kafkamanager
[root@k8s-storage01 kafkamanager]# ll
total 59228
-rw-r--r-- 1 root root 353 Jan 27 17:42 Dockerfile
-rw-r--r-- 1 root root 60639694 Jan 27 17:48 kafka-manager-2.0.0.2.zip
[root@k8s-storage01 kafkamanager]# unzip kafka-manager-2.0.0.2.zip
[root@k8s-storage01 kafkamanager]# ll
total 59228
-rw-r--r-- 1 root root 353 Jan 27 17:42 Dockerfile
drwxr-xr-x 6 root root 4096 Jan 27 18:09 kafka-manager-2.0.0.2
-rw-r--r-- 1 root root 60639694 Jan 27 17:48 kafka-manager-2.0.0.2.zip
[root@k8s-storage01 kafkamanager]# cd kafka-manager-2.0.0.2/conf/
[root@k8s-storage01 conf]# vim application.conf
...........
...........
kafka-manager.zkhosts="zok-0.zk-hs.wiseco.svc.cluster.local:2181,zok-1.zk-hs.wiseco.svc.cluster.local:2181,zok-2.zk-hs.wiseco.svc.cluster.local:2181"
...........
...........
basicAuthentication.enabled=true #这里启用了用户密码登录，默认false不启用 (除了这里启用用户登录, 后面也可以启用ldap)
basicAuthentication.enabled=${?KAFKA_MANAGER_AUTH_ENABLED}
...........
...........
basicAuthentication.username="admin"
basicAuthentication.username=${?KAFKA_MANAGER_USERNAME}
basicAuthentication.password="AdMin@123" #修改用户登录密码
basicAuthentication.password=${?KAFKA_MANAGER_PASSWORD}
...........
...........
重新打包
[root@k8s-storage01 conf]# cd ../../
[root@k8s-storage01 kafkamanager]# ll
total 59228
-rw-r--r-- 1 root root 353 Jan 27 17:42 Dockerfile
drwxr-xr-x 6 root root 4096 Jan 27 18:09 kafka-manager-2.0.0.2
-rw-r--r-- 1 root root 60639694 Jan 27 17:48 kafka-manager-2.0.0.2.zip
[root@k8s-storage01 kafkamanager]# rm -rf kafka-manager-2.0.0.2.zip
[root@k8s-storage01 kafkamanager]# tar -zvcf kafka-manager-2.0.0.2.tar.gz kafka-manager-2.0.0.2
[root@k8s-storage01 kafkamanager]# rm -rf kafka-manager-2.0.0.2
[root@k8s-storage01 kafkamanager]# ll
total 58000
-rw-r--r-- 1 root root 353 Jan 27 17:42 Dockerfile
-rw-r--r-- 1 root root 59387703 Jan 27 18:13 kafka-manager-2.0.0.2.tar.gz
制作Dockerfile镜像
[root@k8s-storage01 kafkamanager]# cat Dockerfile
FROM 192.168.10.10/wiseco/jdk1.8.0_192
RUN rm -f /etc/localtime \
&& ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone
ENV LANG en_US.UTF-8
ADD kafka-manager-2.0.0.2.tar.gz /opt/
RUN mv /opt/kafka-manager-2.0.0.2 /opt/kafka-manager
EXPOSE 9000
CMD ["/opt/kafka-manager/bin/kafka-manager"]
上传到harbor仓库
[root@k8s-storage01 kafkamanager]# docker build -t 192.168.10.10/wiseco/kafka-manager-2.0.0.2:v1 .
[root@k8s-storage01 kafkamanager]# docker push 192.168.10.10/wiseco/kafka-manager-2.0.0.2:v1
二、创建kafkamanager的pod
[root@k8s-master01 kafkamanager]# pwd /opt/k8s/k8s-project/kafka_zk/kafkamanager [root@k8s-master01 kafkamanager]# cat kafkamanager.yaml apiVersion: v1 kind: Service metadata: name: kafkamanager namespace: wiseco labels: app: kafkamanager spec: type: NodePort selector: app: kafkamanager ports: - name: http port: 9000 targetPort: 9000 nodePort: 39921 --- apiVersion: apps/v1 kind: Deployment metadata: name: kafkamanager namespace: wiseco spec: replicas: 1 minReadySeconds: 10 strategy: rollingUpdate: maxSurge: 1 maxUnavailable: 0 type: RollingUpdate selector: matchLabels: app: kafkamanager template: metadata: labels: app: kafkamanager spec: affinity: podAntiAffinity: requiredDuringSchedulingIgnoredDuringExecution: - labelSelector: matchExpressions: - key: "app" operator: In values: - kafkamanager topologyKey: "kubernetes.io/hostname" terminationGracePeriodSeconds: 120 containers: - name: kafkamanager image: 192.168.10.10/wiseco/kafka-manager-2.0.0.2:v1 imagePullPolicy: Always ports: - name: cport containerPort: 9000 resources: requests: cpu: 100m memory: 100Mi limits: cpu: 500m memory: 400Mi lifecycle: postStart: exec: command: ["/bin/sh","-c","touch /tmp/health"] livenessProbe: exec: command: ["test","-e","/tmp/health"] initialDelaySeconds: 5 timeoutSeconds: 5 periodSeconds: 10 readinessProbe: tcpSocket: port: cport initialDelaySeconds: 15 timeoutSeconds: 5 periodSeconds: 20
创建并查看
[root@k8s-master01 kafkamanager]# kubectl apply -f kafkamanager.yaml [root@k8s-master01 kafkamanager]# kubectl get pods -n wiseco|grep kafkamanager kafkamanager-6b966689f6-mr9tq 1/1 Running 0 2m51s [root@k8s-master01 kafkamanager]# kubectl get svc -n wiseco|grep kafkamanager kafkamanager NodePort 10.254.240.254 <none> 9000:39921/TCP 2m55s
三、kafkamanager访问
