jumpserver的官方文档 搭建过程主要分三步:

  • 部署mysql
  • 部署redis
  • 部署jumpserver

部署mysql

k8s单节点部署

为了方便访问,可以添加ingress域名来访问

[root@k8s01 home]# cat test-ing.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: test-ing
  namespace: test-env
  annotations:
    kubernetes.io/ingress.class: traefik            
    traefik.ingress.kubernetes.io/router.entrypoints: web
spec:
  rules:
  - host: jumpserver.k8s.com                           
    http:
      paths:
      - path: /              
        backend:
          serviceName: jumpserver-svc
          servicePort: 80

本地host添加相应解析即可
