一、创建NFS动态卷持久化存储
1、创建NFS服务端
[root@work03 ~]# yum install nfs-utils rpcbind -y
[root@work03 ~]# systemctl start nfs
[root@work03 ~]# systemctl start rpcbind
[root@work03 ~]# systemctl enable nfs
[root@work03 ~]# systemctl enable rpcbind
[root@work03 ~]# mkdir -p /data/mongodb/
[root@work03 ~]# vim /etc/exports
/data/mongodb/ *(rw,sync,no_root_squash,no_all_squash)
[root@work03 ~]# systemctl restart rpcbind
[root@work03 ~]# systemctl restart nfs
[root@work03 ~]# showmount -e localhost
Export list for localhost:
/data/nfs *
2、创建动态卷提供者
(1)创建service-rbac
apiVersion: v1
kind: ServiceAccount
metadata:
name: nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: kube-system
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: nfs-client-provisioner-runner
rules:
- apiGroups: [""]
resources: ["persistentvolumes"]
verbs: ["get", "list", "watch", "create", "delete"]
- apiGroups: [""]
resources: ["persistentvolumeclaims"]
verbs: ["get", "list", "watch", "update"]
- apiGroups: ["storage.k8s.io"]
resources: ["storageclasses"]
verbs: ["get", "list", "watch"]
- apiGroups: [""]
resources: ["events"]
verbs: ["create", "update", "patch"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: run-nfs-client-provisioner
subjects:
- kind: ServiceAccount
name: nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: kube-system
roleRef:
kind: ClusterRole
name: nfs-client-provisioner-runner
apiGroup: rbac.authorization.k8s.io
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: leader-locking-nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: kube-system
rules:
- apiGroups: [""]
resources: ["endpoints"]
verbs: ["get", "list", "watch", "create", "update", "patch"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: leader-locking-nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: kube-system
subjects:
- kind: ServiceAccount
name: nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: kube-system
roleRef:
kind: Role
name: leader-locking-nfs-client-provisioner
apiGroup: rbac.authorization.k8s.io
kubectl apply -f service-rbac.yaml
(2)创建nfs-provisioner-deploy
vim nfs-provisioner-deploy.yaml
kind: Deployment
apiVersion: apps/v1
metadata:
name: rabbitmq-nfs
namespace: kube-system
spec:
selector:
matchLabels:
app: rabbitmq-nfs
replicas: 3
strategy:
type: Recreate
template:
metadata:
labels:
app: rabbitmq-nfs
spec:
serviceAccount: nfs-client-provisioner
imagePullSecrets:
- name: regcred
containers:
- name: rabbitmq-nfs
image: 192.168.0.107:80/heosun/nfs-client-provisioner:v1.0
volumeMounts:
- name: rabbitmq-nfs-root
mountPath: /persistentvolumes
env:
- name: PROVISIONER_NAME
value: asd
- name: NFS_SERVER
value: 192.168.0.108
- name: NFS_PATH
value: /data/rabbitmq
volumes:
- name: rabbitmq-nfs-root
nfs:
server: 192.168.0.108
path: /data/rabbitmq
(4)创建storageclass
vim storageclass.yaml
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: rabbitmq-nfs
provisioner: asd
kubectl apply -f storageclass.yaml
二、部署rabbitmq
一、下载插件
mkdir plugins && cd plugins
wget https://github.com/rabbitmq/rabbitmq-autocluster/releases/download/0.10.0/autocluster-0.10.0.ez
wget https://github.com/rabbitmq/rabbitmq-autocluster/releases/download/0.10.0/rabbitmq_aws-0.10.0.ez
二、创建Dockerfile
cd ../
vim Dockerfile
FROM rabbitmq:3.6.8
MAINTAINER Idiom
ENV RABBITMQ_USE_LONGNAME=true \
AUTOCLUSTER_LOG_LEVEL=debug \
AUTOCLUSTER_CLEANUP=true \
CLEANUP_INTERVAL=60 \
CLEANUP_WARN_ONLY=false \
AUTOCLUSTER_TYPE=k8s \
LANG=en_US.UTF-8
ADD plugins/*.ez /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.8/plugins/
RUN rabbitmq-plugins enable --offline autocluster
RUN rabbitmq-plugins enable --offline rabbitmq_management
docker build -t 172.16.0.14:5000/pointsmart/rabbitmq3.7:v4 .
docker push 172.16.0.14:5000/pointsmart/rabbitmq3.7:v4 (没有私有harbor可以省略此步骤)
三、生成cookie文件
vim erlang-cookie.sh
#! /bin/bash
echo $(openssl rand -base64 32) > erlang.cookie
kubectl create secret generic erlang.cookie --from-file=erlang.cookie
sh erlang-cookie.sh
四、配置rbac
vim rabbitmq-rbac.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: rabbitmq
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
name: endpoint-reader
rules:
- apiGroups: [""]
resources: ["endpoints"]
verbs: ["get"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
name: endpoint-reader
subjects:
- kind: ServiceAccount
name: rabbitmq
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: Role
name: endpoint-reader
五、编写service
vim serveice-rabbitmq.yaml
kind: Service
apiVersion: v1
metadata:
name: rabbitmq-service
spec:
type: NodePort
ports:
- name: mangement
protocol: TCP
port: 15672
nodePort: 32001
- name: smp
protocol: TCP
port: 5672
nodePort: 32002
selector:
app: rabbitmq
---
apiVersion: v1
kind: Service
metadata:
name: rabbitmq
labels:
app: rabbitmq
spec:
clusterIP: None
ports:
- port: 5672
name: amqp
selector:

六、编写StatefulSet
vim StatefulSet.yaml
apiVersion: apps/v1beta1
kind: StatefulSet
metadata:
name: rabbitmq
spec:
serviceName: rabbitmq
replicas: 3
template:
metadata:
labels:
app: rabbitmq
spec:
serviceAccountName: rabbitmq
imagePullSecrets:
- name: regsecret
containers:
- name: rabbitmq
image: 172.16.0.14:5000/pointsmart/rabbitmq3.7:v4
imagePullPolicy: IfNotPresent
resources:
requests:
memory: "256Mi"
cpu: "150m"
limits:
memory: "512Mi"
cpu: "250m"
volumeMounts:
- name: rabbitmq-data
mountPath: /var/lib/rabbitmq/mnesia
ports:
- containerPort: 5672
name: amqp
env:
- name: RABBITMQ_DEFAULT_USER
value: comma
- name: RABBITMQ_DEFAULT_PASS
value: commaai2017
- name: RABBITMQ_ERLANG_COOKIE
valueFrom:
secretKeyRef:
name: erlang.cookie
key: erlang.cookie
- name: MY_POD_NAME
valueFrom:
fieldRef:
fieldPath: metadata.name
- name: K8S_SERVICE_NAME
value: "rabbitmq"
- name: RABBITMQ_USE_LONGNAME
value: "true"
- name: RABBITMQ_NODENAME
value: "rabbit@$(MY_POD_NAME).$(K8S_SERVICE_NAME)"
- name: RABBITMQ_NODE_TYPE
value: disc
- name: AUTOCLUSTER_TYPE
value: "k8s"
- name: AUTOCLUSTER_DELAY
value: "10"
- name: AUTOCLUSTER_CLEANUP
value: "true"
- name: CLEANUP_WARN_ONLY
value: "false"
- name: K8S_ADDRESS_TYPE
value: "hostname"
- name: K8S_HOSTNAME_SUFFIX
value: ".$(K8S_SERVICE_NAME)"
volumeClaimTemplates:
- metadata:
name: rabbitmq-data
annotations:
volume.beta.kubernetes.io/storage-class: rabbitmq-nfs
spec:
accessModes: [ "ReadWriteOnce" ]
resources:
requests:
storage: 1Gi
kubectl create -f storageclass.yaml
kubectl create -f nfs-provisioner-deploy.yaml
kubectl create -f rabbitmq-statefulset.yaml
kubectl create -f serveice-rabbitmq.yaml
kubectl create -f rabbitmq-rbac.yaml
七、进入主容器创建用户
kubectl exec -it rabbitmq-0 -- /bin/bash #进入容器
rabbitmqctl stop_app #停止rabbitmq
rabbitmqctl reset #设置rabbitmq可更改
rabbitmqctl start_app #开启rabbitmq
rabbitmqctl delete_user guest #删除guest用户
rabbitmqctl add_user 用户名 密码 #创建用户
rabbitmqctl set_user_tags 用户名 administrator #增加权限
八、登录方式
node节点:32001
