使用k8s部署nginx文件服务器

需要使用nginx部署一个外网文件服务器使用k8s部署
本次需要把一个apk文件映射到外网
前提条件

1. 部署好的k8s集群
2. 部署好的存储集群(glusterfs,NFS)

k8s的yaml配置文件

deployment文件
使用以下命令生成再修改

#  kubectl run apk-nginx --image=192.168.3.61/foundation/nginx --dry-run -o yaml

# cat apk-nginx-deployment.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    run: apk-nginx
  name: apk-nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      run: apk-nginx
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        run: apk-nginx
    spec:
      containers:
      - image: 192.168.3.61/foundation/nginx
        name: apk-nginx
        resources: {}
        volumeMounts:
        - name: apk-nginx-volume
          mountPath: "/usr/share/nginx/html"
          readOnly: false
        - name: apk-nginx
          mountPath: /etc/nginx/conf.d/default.conf
          subPath: default.conf
      volumes:
      - name: apk-nginx-volume
        persistentVolumeClaim:
          claimName: apk-nginx-pvc
      - name: apk-nginx
        configMap:
          name: apk-nginx
status: {}

service的yaml配置文件
本次固定的NodePort的端口号

# cat apk-nginx-service.yaml 
apiVersion: v1
kind: Service
metadata:
  creationTimestamp: null
  labels:
    run: apk-nginx
  name: apk-nginx
spec:
  ports:
  - port: 80
    protocol: TCP
    targetPort: 80
  selector:
    run: apk-nginx
  type: NodePort
  ports:
  - nodePort: 30336
    port: 80  
status:
  loadBalancer: {}

动态存储pvc的yaml文件
前提需要搭建好动态存储本次使用Heketi管理的GlusterFS存储
参考
https://www.cnblogs.com/minseo/p/12575604.html

]# cat apk-nginx-pvc.yaml 
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: apk-nginx-pvc
  namespace: default
  #annotations:
  #  volume.beta.kubernetes.io/storage-class: "glusterfs"
spec:
  #与storageclass名字对应
  storageClassName: gluster-heketi-storageclass
  # ReadWriteOnce：简写RWO，读写权限，且只能被单个node挂载；
  # ReadOnlyMany：简写ROX，只读权限，允许被多个node挂载；
  # ReadWriteMany：简写RWX，读写权限，允许被多个node挂载；
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 2Gi

nginx配置文件
因为需要使用文件服务器修改配置文件如下

# cat default.conf 
autoindex on;# 显示目录
autoindex_exact_size on;# 显示文件大小
autoindex_localtime on;# 显示文件时间
charset utf-8,gbk;#如果包含中文文件夹需要加此配置否则乱码
server {
    listen       80;
    server_name  localhost;
    root         /usr/share/nginx/html;
}

创建配置文件用于挂载至Pod

# 创建配置文件名称为apk-nginx 是从文件default.conf创建的
# kubectl create configmap apk-nginx --from-file=default.conf

使用以下命令查看创建的配置文件

# kubectl get configmaps apk-nginx -o yaml
apiVersion: v1
data:
  default.conf: |
    autoindex on;# 显示目录
    autoindex_exact_size on;# 显示文件大小
    autoindex_localtime on;# 显示文件时间
    charset utf-8,gbk;#如果包含中文文件夹需要加此配置否则乱码
    server {
        listen       80;
        server_name  localhost;
        root         /usr/share/nginx/html;
    }
kind: ConfigMap
metadata:
  creationTimestamp: "2024-01-18T07:13:53Z"
  name: apk-nginx
  namespace: default
  resourceVersion: "11824529"
  selfLink: /api/v1/namespaces/default/configmaps/apk-nginx
  uid: 231faf36-b5d1-11ee-ae4a-525400e71cb5

应用所有yaml文件

# kubectl apply -f *.yaml

把需要外网访问的文件复制至容器，因为挂载了存储相当于复制到存储内

# kubectl cp README.md apk-nginx-58dd77957d-mj4k5:/usr/share/nginx/html

访问
任意node的ip+端口

# http://nodeIp:port
