描述

简介

JumpServer是一款免费开源的堡垒机，可以帮助企业以更安全的方式管控和登录各种类型的资产。

JumpServer 堡垒机支持事前授权、事中监察、事后审计，满足等保合规要求。

使用Helm安装JumpServer

在K8s上部署MySQL

由于JumpServer需要使用外部MySQL，因此需要自己配置

添加Helm源
helm repo add bitnami https://charts.bitnami.com/bitnami

下载MySQL Helm Chart

helm fetch bitnami/mysql

tar -xf mysql-9.12.3.tgz

[root@node1 jumpserver]
[root@node1 mysql]
Chart.lock  charts  Chart.yaml  README.md  templates  values.schema.json  values.yaml

修改其中的values.yaml文件，内容如下

global:
  imageRegistry: ""
   
  imagePullSecrets: []
  storageClass: "csi-rbd-sc"  
auth:
  
  
  
  rootPassword: "mysql_password"  
  
  
  
  createDatabase: true  
  
  
  
  database: "jumpserver"  
  
  
  
  username: "jms"        
  
  
  password: "jms_password"  
  
  
    livenessProbe:
        enabled: true
        initialDelaySeconds: 60  
        periodSeconds: 60  
        timeoutSeconds: 10 
        failureThreshold: 3
        successThreshold: 1
    readinessProbe:
        enabled: true
        initialDelaySeconds: 60
        periodSeconds: 60
        timeoutSeconds: 10
        failureThreshold: 3
        successThreshold: 1 
    startupProbe:
        enabled: true
        initialDelaySeconds: 60
        periodSeconds: 60
        timeoutSeconds: 10
        failureThreshold: 10
        successThreshold: 1

创建名称空间

创建名称空间kms，后面的服务都部署在该名称空间下

kubectl create ns jms

部署MySQL

helm install jms-mysql . -f values.yaml -n jms

在k8s上部署redis

由于JumpServer需要使用外部redis，因此也需要自己配置

下载Redis Helm Chart

helm fetch bitnami/redis

tar -xf redis-18.0.4.tgz


[root@node1 jumpserver]
[root@node1 redis]
Chart.lock  charts  Chart.yaml  img  README.md  templates  values.schema.json  values.yaml

修改values.yaml文件内容如下

global:
  imageRegistry: ""
  
  
   imagePullSecrets: []
  storageClass: "csi-rbd-sc"  
  redis:
    password: "redis_password"

应用Chart

helm install jms-redis . -f values.yaml  -n jms

查看Pod

[root@node1 redis]
NAME                   READY   STATUS    RESTARTS   AGE
jms-mysql-0            1/1     Running   0          14m
jms-redis-master-0     1/1     Running   0          3m5s
jms-redis-replicas-0   1/1     Running   0          3m5s
jms-redis-replicas-1   1/1     Running   0          119s
jms-redis-replicas-2   1/1     Running   0          77s

部署JumpServer

添加Helm源

helm repo add jumpserver https://jumpserver.github.io/helm-charts

搜索JumpServer Helm Chart

[root@node1 jumpserver]
NAME                    CHART VERSION   APP VERSION     DESCRIPTION                                       
jumpserver/jumpserver   3.8.1           v3.8.1          A Helm chart for Deploying Jumpserver on K

ubern...

下载Helm Chart 以便修改其中的values.yml

helm fetch jumpserver/jumpserver

如果上一步下载网速慢无法下载的话可以克隆github项目

git clone https://github.com/jumpserver/helm-charts.git

修改values.yaml

[root@node1 jumpserver]
/root/jumpserver/helm-charts/charts/jumpserver
[root@node1 jumpserver]
Chart.yaml  configs  README.md  templates  values.yaml

修改values.yaml内容如下

[root@node1 ~]
2c8jbQPosNKb2pC1iGkFwMHwYwg0XYaykCPiAeO8PccHAixbih


[root@node1 ~]
wF3NSIDTGGtO22cUNwBRV808


global:
  imageRegistry: "docker.io"  
  imageTag: v3.8.1
  
  
   imagePullSecrets: []
  storageClass: "csi-rbd-sc"  


externalDatabase:
  engine: mysql
  host: jms-mysql  
  port: 3306
  user: jms       
  password: "jms_password"
  database: jumpserver


externalRedis:
  host: localhost
  port: 6379
  password: "redis_password"
core:
  enabled: true


  labels:
    app.jumpserver.org/name: jms-core


  config:
    
    secretKey: "2c8jbQPosNKb2pC1iGkFwMHwYwg0XYaykCPiAeO8PccHAixbih"  
    
    bootstrapToken: "wF3NSIDTGGtO22cUNwBRV808" 
    
accessModes:
  - ReadWriteOnce

应用Chart

该步骤时间可能会较长

helm install jumpserver . -f values.yaml -n jms

使用Istio暴露jumpserver web服务

创建gateway


apiVersion: networking.istio.io/v1beta1
kind: Gateway
metadata:
  name: jumpserver-gateway
  namespace: istio-system
spec:
  selector:
    app: istio-ingressgateway
  servers:
  - port:
     number: 80
     name: http
     protocol: HTTP
    hosts:
    - "jumpserver.myk8s.cn"


应用yaml文件
kubectl apply -f jumpserver-gateway.yaml


创建VirtualService


apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: jumpserver-virtualservice
  namespace: jms
spec:
  hosts:
  - "jumpserver.myk8s.cn"
  gateways:
  - istio-system/jumpserver-gateway
  http:
  - match:
     - uri:
         prefix: /
    route:
    - destination:
        host: jumpserver-jms-web
        port:
          number: 80


应用yaml文件
[root@node1 jumpserver]
virtualservice.networking.istio.io/jumpserver-virtualservice created

在需要访问jumpserver服务的主机上修改hosts,将jumpserver.myk8s.cn解析为external-ip地址，这里解析为192.168.0.111
