如何使用ansible playbook写出jumpserver+keepalived高可用，jumpserver使用docker运行，请写出详细命令或步骤

您好！关于您的问题，我可以为您提供一些帮助。首先，您需要在Ansible中编写一个playbook来实现JumpServer的高可用性。以下是一些步骤：

1. 安装Ansible

在您的控制节点上安装Ansible。

2. 安装Docker

在您的JumpServer主机上安装Docker。

3. 编写playbook

在您的控制节点上编写一个playbook，包括以下操作：

- 安装keepalived
- 配置keepalived
- 配置Docker
- 部署JumpServer容器

以下是一个简单的playbook示例：

---
- name: Deploy JumpServer with keepalived
  hosts: jumpserver
  become: yes
  
  vars:
    vip: 192.168.1.10
    jumpserver_image: jumpserver/jms_all:latest
    
  tasks:
  - name: Install keepalived
    apt:
      name: keepalived
      state: present
  
  - name: Configure keepalived
    template:
      src: templates/keepalived.conf.j2
      dest: /etc/keepalived/keepalived.conf
    notify: restart keepalived
  
  - name: Configure Docker
    lineinfile:
      path: /etc/docker/daemon.json
      line: "{{ item }}"
    with_items:
      - '{"live-restore": true}'
      - '{"log-driver": "journald"}'
    notify: restart Docker
  
  - name: Deploy JumpServer
    docker_container:
      name: jumpserver
      image: "{{ jumpserver_image }}"
      ports:
        - "80:80"
        - "2222:2222"
      env:
        DB_HOST: db
        DB_PORT: 3306
        DB_USER: jumpserver
        DB_PASSWORD: jumpserver
      restart: always
    notify: restart keepalived
  
  handlers:
  - name: restart keepalived
    service:
      name: keepalived
      state: restarted
  
  - name: restart Docker
    systemd:
      name: docker
      state: restarted

4. 运行playbook

在您的控制节点上执行playbook，例如：

ansible-playbook -i inventory.ini deploy_jumpserver.yml

以上就是一个简单的Ansible playbook实现JumpServer的高可用性。希望能对您有所帮助！
