site.yml 文件内容说明 - hosts: all # 所有客户机 user: root #root用户执行 vars: network_card: eth0 # 添加macvlan 参加 本地网卡名字根据实际情况修改 subnet: 192.168.0.0/21 # 网段跟宿主机一个网段 gateway: 192.168.0.210 # 网关docker 使用 netname: eth0_1 #docker macvlan 网卡名字 roles: - docker_client # docker 安装项目
main.yml 文件内容说明
- stat: path=/usr/bin/docker # 判断是否安装docker register: docker_path_register - name: yum old docker yum: name=docker* state=removed # 卸载docker when: docker_path_register.stat.exists == True # 已经安装卸载已经安装docker - name: cp docker.repo client template: src=http://www.mamicode.com/docker.repo dest=/etc/yum.repos.d/docker.repo # 上传最新docker yum 源到客户机"ip link set {{ network_card }} promisc on" #添加 打开网卡混合模式 必须打开不然docker macvlan 不能访问外面网络 - name: ip link set {{ network_card }} promisc on 打开 立即生效 shell: ip link set {{ network_card }} promisc on - name: docker network ls |grep macvlan shell: docker network ls |grep macvlan # 判断是否添加docker macvlan 网卡 register: result ignore_errors: True # 忽略错误 - name: create docker macvlan shell: docker network create -d macvlan --subnet={{ subnet }} --gateway={{ gateway }} -o parent={{ network_card }} -o macvlan_mode=bridge {{ netname }} # 配置docker macvlan 网卡 when: result.rc == True #result 返回真执行
其它说明:
ansible-playbook -i hosts site.yml -verbose 执行 docker macvlan 使用 docker run -it -d --net=eth0_1(docker macvlan 网卡名字 ) --ip=192.168.2.210 (docker ip) d0de804bd957(docker image) /usr/sbin/init
