amazon-web-services - 使用 AWS Go 开发工具包的动态 list

Question

如前所述here , 如果您使用的是云提供商，则不应在静态文件中管理您的库存。而是使用动态库存

Ansible 文档仅提供 python boto sdk 作为动态库存，如图 here .

     ansible -i ec2.py -u ubuntu us-east-1d -m ping

ansible 是否允许( -i)执行使用 AWS Go sdk 编写的动态 list ？而不是 python boto sdk。

是的，ansible 将使用任何可以产生必要的 JSON 输出的命令，包括一个 shell 脚本，由 the fine manual 指定。 :

In previous versions you had to create a script or program that can output JSON in the correct format when invoked with the proper arguments. You can still use and write inventory scripts, as we ensured backwards compatibility via the script inventory plugin and there is no restriction on the programming language used.

作为一个具体的 golang 示例:

package main
import (
    "encoding/json"
    "fmt"
)
func main() {
    i := map[string]interface{}{
        "_meta": map[string]interface{}{
            "hostvars": map[string]interface{}{
                "example.host": map[string]interface{}{
                    "ansible_host": "127.0.0.1",
                    "ansible_user": "ubuntu",
                },
            },
        },
        "all": map[string]interface{}{
            "children": []string{"ungrouped"},
        },
        "ungrouped": map[string]interface{}{
            "hosts": []string{"example.host"},
        },
    }
    ba, err := json.Marshal(i)
    if err != nil { panic(err) }
    fmt.Println(string(ba))
}

通过通常的机制调用:

go build -o sample-inv ./main.go
ansible -i ./sample-inv -m ping all
