前言：最近在給公司搞kafka和zookeeper容器化結(jié)合rancher的項目，查閱了相關官網(wǎng)和書籍，發(fā)現(xiàn)如果和公司的標準化關聯(lián)比較牽強，原因有很多，我簡單談一下我最后選擇自定義的原因：（因是個人本地二進制部署k8s+kakfa測試的，因此生產(chǎn)需要自己配置所需要的內(nèi)存和cpu，動態(tài)持久化存儲等）
1、使用官網(wǎng)dockfile不能自定義jdk。
2、dockerfile和yaml關聯(lián)比較牽強，每個人有每個人的思路。
3、不能和公司之前物理機部署標準化文檔相結(jié)合。
.....
下面，我將花了半個月研究的部署分享一，有興趣者可加好友共同探討：

1.2） zookeeper文件清單詳解
1.2.1）oracle jdk軟件包
? jdk-8u151-linux-x64.tar.gz
底層使用centos6.6鏡像，部署目錄到app目錄下，在dockerfile里面配置環(huán)境變量。
1.2.2）zookeeper軟件包
? zookeeper-3.4.12.tar.gz
底層使用centos6.6鏡像，部署目錄到app目錄下

docker build -t zookeeper:3.4.12 -f zookeeper.Dockerfile .
docker tag zookeeper:3.4.12 192.168.8.183/library/zookeeper-zyxf:3.4.12
1.3.2）zookeeper鏡像上傳harbor倉庫

docker push 192.168.8.183/library/zookeeper-zyxf

1.4）zookeeper部署

1.4）zookeeper部署
1.4.1）zookeeper部署
kubectl apply -f zookeeper.yaml
1.4.2）zookeeper部署過程檢查
[root@node7 ~]# kubectl describe pods zookeeper-
zookeeper-0 zookeeper-1 zookeeper-2
kubectl get pods -w -l app=zookeeper

1.5） zookeeper集群驗證
1.5.1）檢查 zookeeper StatefulSet 中 Pods 分布
[root@node7 ~]# kubectl get pods -o wide

1.5.2）檢查 zookeeper StatefulSet 中 Pods 主機名
for i in 0 1 2; do kubectl exec zookeeper-$i – hostname ; done

1.5.3) 檢查 zookeeper StatefulSet 中myid標識
for i in 0 1 2; do echo "myid zookeeper-$i";kubectl exec zookeeper-$i -- cat /app/zookeeper/data/myid; done

1.5.4) 檢查 zookeeper StatefulSet 中FQDN (正式域名)
for i in 0 1 2; do kubectl exec zookeeper-$i -- hostname -f; done

1.5.5) 檢查 zookeeper StatefulSet pods中DNS解析
for i in 0 1 2; do kubectl exec -ti busybox -- nslookup zookeeper-$i.zookeeper-headless.default.svc.cluster.local; done

1.5.6) 檢查 zookeeper StatefulSet zoo.cfg配置文件標準化

1.5.7) 檢查 zookeeper StatefulSet 集群狀態(tài)
for i in 0 1 2; do kubectl exec zookeeper-$i -- /app/zookeeper/bin/zkServer.sh status|grep Mode; done

1.5.8) 檢查 zookeeper StatefulSet 四字命令檢驗

2.3）kafka鏡像生成上傳
2.3.1）zookeeper鏡像打包
docker build -t kafka:2.2.0 -f kafka.Dockerfile .
docker tag kafka:2.2.0 192.168.8.183/library/kafka-zyxf:2.2.0
2.3.2）zookeeper鏡像上傳harbor倉庫
docker login 192.168.8.183 -u admin -p renzhiyuan
docker push 192.168.8.183/library/kafka-zyxf:2.2.0
2.4）kafka部署
2.4.1）kafka部署
kubectl apply -f kafka.yaml
2.4.2）kafka部署過程檢查
[root@node7 ~]# kubectl describe pods kafka-
kafka-0 kafka-1 kafka-2
[root@node7 ~]#
kubectl get pods -w -l app=kafka

2.5）kafka集群驗證
2.5.1）檢查 kafka StatefulSet 中 Pods 分布

2.5.2）檢查 kafka StatefulSet 中 Pods 主機名
for i in 0 1 2; do kubectl exec kafka-$i -- hostname ; done

2.5.3) 檢查 kafka StatefulSet 中FQDN (正式域名)
for i in 0 1 2; do kubectl exec kafka-$i -- hostname -f; done

2.5.4) 檢查 kafka StatefulSet pods中dns解析
for i in 0 1 2; do kubectl exec -ti busybox -- nslookup kafka-$i.kafka-headless.default.svc.cluster.local; done

2.5.5) 檢查 kafka StatefulSet server.properties配置文件標準化
for i in 0 1 2; do echo kafka-$i; kubectl exec kafka-$i cat /app/kafka/logs/server.log|grep "auto.create.topics.enable = false"; done
2.5.6) 檢查 kafka StatefulSet 集群驗證
? 創(chuàng)建一個topic
kubectl exec kafka-1 -- /app/kafka/bin/kafka-topics.sh --create --zookeeper zookeeper:2181 --replication-factor 3 --partitions 6 --topic renzhiyuan
? 檢查topic信息
kubectl exec kafka-1 -- /app/kafka/bin/kafka-topics.sh --describe --zookeeper zookeeper:2181 --topic renzhiyuan
?
生產(chǎn)消息
/app/kafka/bin/kafka-console-producer.sh --broker-list kafka:9092 --topic renzhiyuan

? 消費消息
/app/kafka/bin/kafka-console-consumer.sh --bootstarp-server kafka:9092 --from-beginning --topic renzhiyuan


2.6）kafka集群擴容
2.3.1）kafka擴容到6實例
kubectl scale --replicas=6 StatefulSet/kafka
statefulset.apps/kafka scaled
[root@node7 ~]#
2.3.2）kafka擴容過程檢查
[root@node7 ~]# kubectl describe pods kafka-
kafka-0 kafka-2 kafka-4
kafka-1 kafka-3 kafka-5
[root@node7 ~]#
kubectl get pods -w -l app=kafka

? 創(chuàng)建一個topic
kubectl exec kafka-3 -- /app/kafka/bin/kafka-topics.sh --create --zookeeper zookeeper:2181 --replication-factor 3 --partitions 6 --topic renzhiyuan2
? 檢查topic信息
kubectl exec kafka-3 -- /app/kafka/bin/kafka-topics.sh --describe --zookeeper zookeeper:2181 --topic renzhiyuan2

三、 Kafka manager管理端部署
3.1）kafka manager文件清單

3.2） kafka manager文件清單詳解
3.3）kafka manager 鏡像生成上傳
3.3.1）zookeeper鏡像打包
docker build -t kafka-manager:1.3.3.18 -f manager.Dockerfile .
docker tag kafka-manager:1.3.3.18 192.168.8.183/library/ kafka-manager-zyxf: 1.3.3.18
3.3.2）zookeeper鏡像上傳harbor倉庫
docker login 192.168.8.183 -u admin -p renzhiyuan
docker push 192.168.8.183/library/kafka-manager-zyxf

3.4）kafka manager 部署
[root@node7 ~]# kubectl apply -f manager.yaml
3.5）kafka manager驗證

http://192.168.8.181:32009/
3.5.1）擴容前驗證

3.5.2）擴容后驗證
