JumpServer是一款免費(fèi)開(kāi)源的堡壘機(jī)，可以幫助企業(yè)以更安全的方式管控和登錄各種類(lèi)型的資產(chǎn)。

JumpServer 堡壘機(jī)支持事前授權(quán)、事中監(jiān)察、事后審計(jì)，滿足等保合規(guī)要求。

使用Helm安裝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

下載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，內(nèi)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

創(chuàng)建名稱(chēng)空間

創(chuàng)建名稱(chēng)空間kms，后面的服務(wù)都部署在該名稱(chēng)空間下

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

下載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文件內(nèi)容如下

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

應(yīng)用Chart

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

查看Pod

[root@node1 redis]

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...

下載Helm Chart 以便修改其中的values.yml

helm fetch jumpserver/jumpserver

如果上一步下載網(wǎng)速慢無(wú)法下載的話可以克隆github項(xiàng)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內(nèi)容如下
