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
查看Pod

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
测试

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
访问服务
