說明

我們用ansible的facts變量獲取系統(tǒng)的信息是最方便的. 但是我們的服務(wù)器有存在多ip的情況.自己看一下

ansible 192.168.10.106 -m setup|more

看輸出需要獲取什么值

 "ansible_facts": {
        "ansible_all_ipv4_addresses": [
            "192.168.10.106", 
            "192.168.10.69", 
            "192.168.10.218"
        ], 
------------------------------------------------------------
        "ansible_default_ipv4": {
            "address": "192.168.10.106", 
            "alias": "ens192",
----------------------------------------------------------
        "ansible_ens192": {
            "active": true, 
            "device": "ens192",
            "ipv4": {
                "address": "192.168.10.106", 
                "broadcast": "192.168.10.255", 
                "netmask": "255.255.255.0", 
                "network": "192.168.10.0"
            }, 
            "ipv4_secondaries": [
                {
                    "address": "192.168.10.69", 
                    "broadcast": "192.168.10.255", 
                    "netmask": "255.255.255.0", 
                    "network": "192.168.10.0"
                }, 
                {
                    "address": "192.168.10.218", 
                    "broadcast": "192.168.10.255", 
                    "netmask": "255.255.255.0", 
                    "network": "192.168.10.0"
                }

所以獲取ip的值就用對(duì)應(yīng)的就可以了
ansible_all_ipv4_addresses #適用于多ip, 輸出[u'192.168.10.106', u'192.168.10.69', u'192.168.10.218'], 如果是docker幾十個(gè)ip,也很煩.
ansible_default_ipv4[address] #適用單ip
ansible_ens192[ipv4][address] #因?yàn)楹途W(wǎng)卡綁定,多系統(tǒng)版本的時(shí)候不通用
