K8S部署Kafka界面管理工具(kafkamanager)方法详解

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

                    operator: In
                    values:

      terminationGracePeriodSeconds: 120
      containers:
      - name: kafkamanager
        image: 192.168.10.10/wiseco/kafka-manager-2.0.0.2:v1
        imagePullPolicy: Always

            exec:
              command: ["/bin/sh","-c","touch /tmp/health"]
        livenessProbe:
          exec:
            command: ["test","-e","/tmp/health"]
          initialDelaySeconds: 5
          timeoutSeconds: 5
          periodSeconds: 10
        readinessProbe:
          tcpSocket:

          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
