这里使用Helm安装所以需要先安装一下Helm,如果已经安装跳过2.1这个小步骤
wget https://get.helm.sh/helm-v3.12.1-linux-amd64.tar.gz
,如果遇到卡主那就是需要tar -zxvf helm-v3.12.1-linux-amd64.tar.gz
mv linux-amd64/helm /usr/local/bin/helm
helm repo add bitnami https://charts.bitnami.com/bitnami
,这边如果要添加找其他仓库地址可以去Artifact Hub搜索相对于的仓库地址。vim mongodb-pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: mongodb-pv
spec:
capacity:
storage: 5Gi
accessModes:
- ReadWriteOnce
hostPath:
path: /bitnami/mongodb/data
以上内容中/bitnami/mongodb/data是主机真实路径,小提示如果没有权限需要赋权限给uid为1001
vim mongodb-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mongodb-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 5Gi
volumeName: mongodb-pv
vim mongodb-values.yaml
persistence:
enabled: true
existingClaim: "mongodb-pvc"
securityContext:
privileged: true
runAsUser: 1001
runAsGroup: 1001
fsGroup: 1001
auth:
rootPassword: "自定义密码"
创建完以上三个文件之后按顺序执行如下:
①kubectl apply -f mongodb-pv.yaml
②kubectl apply -f mongodb-pvc.yaml
③helm install my-mongodb bitnami/mongodb -f mongodb-values.yaml --set volumePermissions.enabled=true
提示–set volumePermissions.enabled=true第③必须加这个不然pod创建的时候没有权限创建文件夹及文件会报错mkdir: cannot create directory ‘/bitnami/mongodb/data’: Permission denied
安装成功之后如果想让外网访问跟上面redis一样service编辑type为NodePort,设置nodePort: 27017,端口号自定义只要防火墙对外开放就行
卸载使用helm uninstall my-mongodb
先切换至admin库use admin
再执行修改 db.changeUserPassword("用户名","密码")
前置条件参考第2步安装MongoDB中的创建pv跟pvc命名为kafka-pv和kafka-pvc
replicaCount: 1 # kafka 副本数
#global:
# storageClass: nfs-client # kafka 和 zookeeper 使用的存储
heapOpts: "-Xmx1024m -Xms1024m" # kafka 启动的 jvm 参数
persistence: # kafka 每个副本的存储空间
enabled: true
existingClaim: "kafka-pvc"
resources:
limits:
cpu: 1000m
memory: 2Gi
requests:
cpu: 100m
memory: 100Mi
zookeeper:
replicaCount: 1 # zookeeper 的副本数
persistence:
enabled: true
existingClaim: "kafka-pvc"
resources:
limits:
cpu: 2000m
memory: 2Gi
externalAccess:
enabled: true # 开启外部访问
autoDiscovery:
enabled: true
service:
type: NodePort # 开启 nodeport
ports:
external: 9094
nodePorts: # nodeport 对应的端口,多少个 kafka 副本对应多少个端口
- 30001
# - 30002
# - 30003
执行部署helm install my-kafka bitnami/kafka -f kafka-values.yaml --set volumePermissions.enabled=true --set rbac.create=true
