1、下载文件
https://github.com/dotbalo/k8s/
2、创建namespace
kubectl create namespace public-service
如果不使用public-service，需要更改所有yaml文件的public-service为你namespace。
sed -i "s#public-service#YOUR_NAMESPACE#g" *.yaml
3、创建持久化pv
此处采用的是静态PV方式，后端使用的是NFS，为了方便扩展可以使用动态PV较好。
[root@nfs rabbitmq-cluster-]# cat /etc/exports
/k8s/rmq-cluster/rabbitmq-cluster-/ *(rw,sync,no_subtree_check,no_root_squash)
/k8s/rmq-cluster/rabbitmq-cluster-/ *(rw,sync,no_subtree_check,no_root_squash)
/k8s/rmq-cluster/rabbitmq-cluster-/ *(rw,sync,no_subtree_check,no_root_squash)
[root@k8s-master01 rabbitmq-cluster]# pwd
/root/efk/rabbitmq-cluster
[root@k8s-master01 rabbitmq-cluster]# ls
rabbitmq-cluster-ss.yaml rabbitmq-pv.yaml rabbitmq-secret.yaml rabbitmq-service-lb.yaml
rabbitmq-configmap.yaml rabbitmq-rbac.yaml rabbitmq-service-cluster.yaml README.md
创建集群
[root@k8s-master01 rabbitmq-cluster]# kubectl apply -f .
4、查看
pods、pv、pvc
[root@k8s-master01 rabbitmq-cluster]# kubectl get pods -n public-service
NAME READY STATUS RESTARTS AGE
rmq-cluster- / Running 40m
rmq-cluster- / Running 39m
rmq-cluster- / Running 39m
[root@k8s-master01 rabbitmq-cluster]# kubectl get pv -n public-service
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
pv-rmq- 4Gi RWX Recycle Bound public-service/rabbitmq-storage-rmq-cluster- rmq-storage-class 49m
pv-rmq- 4Gi RWX Recycle Bound public-service/rabbitmq-storage-rmq-cluster- rmq-storage-class 49m
pv-rmq- 4Gi RWX Recycle Bound public-service/rabbitmq-storage-rmq-cluster- rmq-storage-class 49m
[root@k8s-master01 rabbitmq-cluster]# kubectl get pvc -n public-service
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
rabbitmq-storage-rmq-cluster- Bound pv-rmq- 4Gi RWX rmq-storage-class 48m
rabbitmq-storage-rmq-cluster- Bound pv-rmq- 4Gi RWX rmq-storage-class 48m
rabbitmq-storage-rmq-cluster- Bound pv-rmq- 4Gi RWX rmq-storage-class 48m
[root@k8s-master01 rabbitmq-cluster]#
services，此时使用的NodePort方式，可改为traefik模式
[root@k8s-master01 rabbitmq-cluster]# kubectl get services -n public-service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
rmq-cluster ClusterIP None <none> /TCP 1h
rmq-cluster-balancer NodePort 10.107.221.85 <none> :/TCP,:/TCP 1h
5、访问测试
通过NodePort的端口
