Question

我让vagrant配置了多台机器和ansible：

config.vm.box = "ubuntu/trusty64"

config.vm.define "my_server" do |my_server|
    my_server.vm.network "private_network", ip: "192.168.50.4"
end

config.vm.define "my_agent" do |my_agent|
    my_agent.vm.network "private_network", ip: "192.168.50.5"
end

config.vm.provision "ansible" do |ansible|
    ansible.groups = {
        "my-server" => ["my_server"],
        "my-agent" => ["my_agent"],
        "all_groups:children" => ["my-server", "my-agent"]
    }
    ansible.playbook = "./ansible/my.yml"
end

并且vagrant生成库存文件：

# Generated by Vagrant

my_server ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 ansible_ssh_private_key_file=/.../private_key
my_agent ansible_ssh_host=127.0.0.1 ansible_ssh_port=2200 ansible_ssh_private_key_file=/.../private_key
...

当我运行vagrant my_server获取ip：

eth0: 10.0.2.15
eth1: 192.168.50.4

和my_agent获取ip：

eth0: 10.0.2.15
eth1: 192.168.50.5

我想添加服务器的代理配置ip地址（来自eth1）。我尝试调试有关服务器的信息：

- debug: var=hostvars[item]
  with_items: groups['my-server']

但我只得到：

ok: [my_agent] => (item=my_server) => {
    "item": "my_server", 
    "var": {
        "hostvars[item]": {
            "ansible_ssh_host": "127.0.0.1", 
            "ansible_ssh_port": 2222, 
            "ansible_ssh_private_key_file": ".../private_key", 
            "group_names": [
                "all_groups", 
                "my-server"
            ], 
            "inventory_hostname": "my_server", 
            "inventory_hostname_short": "my_server"
        }
    }
}

是否可以在代理角色中获取服务器的IP地址？如果有可能我怎么做呢？

我解决问题。我需要添加

ansible.limit = "all"

在ansible配置中，因为vagrant运行了两次ansible：首先是my_server，第二次是my_agent。第二次回复并不收集有关my_server的信息。现在ansible为每个服务器运行两次。

工作流浪汉配置：

config.vm.provision "ansible" do |ansible|
    ansible.groups = {
        "my-server" => ["my_server"],
        "my-agent" => ["my_agent"],
        "all_groups:children" => ["my-server", "my-agent"]
    }
    ansible.limit = "all"
    ansible.playbook = "./ansible/my.yml"
end

and ansible agent角色：

- debug: var=hostvars[item]["ansible_eth1"]["ipv4"]["address"]
  with_items: groups['my-server']
  sudo: yes

如何从ansible的其他主机获取IP地址？
