概述版本洞察

管理 Docker Machine

Ansible 角色用于管理 Docker Machine 的机器。

安装 Docker Machine
在库存中的每个目标主机上创建 Docker Machine
搜索并替换 Docker Machine 的 config.json 文件，以更改存储目录

您可以查看如何制作剧本、配置和示例命令的示例，链接在这里 https://github.com/winggundamth/ansible-wing-playbook

注意事项

此角色将在本地机器上运行 docker-machine 命令
库存文件中的目标机器名称将是 docker-machine ls 中机器的名称
默认的 Docker Machine 存储路径为剧本的 files/docker-machine。您可以通过 docker_machine_storage_path 变量更改它
此角色旨在成为条件角色，因此在剧本中您需要为特定任务配置变量。您可以在示例剧本部分查看示例
- 将 docker_machine_create 变量设置为 true 以运行 docker-machine create
- 将 docker_machine_manage_config 变量设置为 true 以搜索并替换 Docker Machine 的 config.json

需求

您必须能够通过 SSH 密钥 SSH 到目标主机
