随着公司本地测试环境虚出来的服务器越来越多，所以近日用k8s部署了jumpserver跳板机系统来管理这些虚机，主要涉及到4个文件。
1.因为涉及到回放录像需要保存的问题，所以采用nfs来创建pvc声明，挂载到容器中响应的目录中
pvc声明配置如下：
jumpserver-pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: jumpserver-datadir
  namespace: omc
  annotations:
    volume.beta.kubernetes.io/storage-class: "nfs-storage"
spec:
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 50Gi

2.部署文件
jumpserver.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: jumpserver
  namespace: omc
  labels:
    app.kubernetes.io/instance: jumpserver
    app.kubernetes.io/name: jumpserver
spec:
    replicas: 1
    strategy:
      rollingUpdate:
        maxSurge: 1
        maxUnavailable: 0
      type: RollingUpdate
    selector:
      matchLabels:
        app.kubernetes.io/instance: jumpserver
        app.kubernetes.io/name: jumpserver
    template:
      metadata:
        labels:
          app.kubernetes.io/instance: jumpserver
          app.kubernetes.io/name: jumpserver
      spec:
        containers:
        - env:
          - name: SECRET_KEY
            value: "veDMhBkZHdfjlsafdjaslfbfiewfbiabjfdakwiafndiawbfjwZ"
          - name: BOOTSTRAP_TOKEN
            value: "F9HUa5nfksd532ndsaR"
          - name: DB_ENGINE
            value: "mysql"
          - name: DB_HOST
            value: "172.16.1.54"
          - name: DB_PORT
            value: "3306"
          - name: DB_USER
            value: "jumpserver"
          - name: "DB_PASSWORD"
            value: "fdsajonfwfa"
          - name: DB_NAME
            value: "jumpserver"
          - name: REDIS_HOST
            value: "172.16.1.54"
          - name: REDIS_PORT
            value: "6379"
          - name: REDIS_PASSWORD
            value: "fdsa923nkfs32"
          image: jumpserver/jms_all:1.5.9
          imagePullPolicy: IfNotPresent
          name: jumpserver
          ports:
          - containerPort: 80
            name: http
            protocol: TCP
          - containerPort: 2222
            name: ssh
            protocol: TCP
          volumeMounts:
          - mountPath: /opt/jumpserver/data/media
            name: datadir
        volumes:
        - name: datadir
          persistentVolumeClaim:
            claimName: jumpserver-datadir

这里需要注意

1.将相应的环境变量的值替换成自己的
2.SECRET_KEY和BOOTSTRAP_TOKEN的值可以通过jumpserver官网给的脚步生成
3.数据库和redis的密码不要使用特殊符号，使用特殊符号在初始化的时候配置文件回不正常，导致初始化失败

3 .jumpserver-svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: jumpserver
  namespace: omc
  labels:
    app.kubernetes.io/instance: jumpserver
    app.kubernetes.io/name: jumpserver
spec:
  ports:
  - name: http
    port: 80
    targetPort: 80
    protocol: TCP
  - name: ssh
    port: 2222
    targetPort: 2222
    protocol: TCP
  selector:
    app.kubernetes.io/instance: jumpserver
    app.kubernetes.io/name: jumpserver

4 . 将jumpserver后台通过ingress暴露给集群外部用户
jumpserver-ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: jumpserver-ingress
  namespace: omc
  annotations:
    kubernetes.io/ingress.class: "nginx"
spec:
  tls:
  - hosts:
    - jmp-dev.niucache.com
    secretName: ingress-niucache
  rules:
  - host: jmp-dev.niucache.com
    http:
      paths:
      - path: /
        backend:
          serviceName: jumpserver
          servicePort: 80

5 . 完成上述步骤后，要访问跳板机管理的服务器，好像只能通过后台才行，所以还有最后一步，我们得想办法将可以通过终端连接的2222端口暴露出来，可以使用ingress-nginx反向代理tcp的功能来实现这个需求，当然也可以在k8s系统中部署一个nginx，专门用来完成代理k8s系统中需要暴露给集群外部的端口。
