Question

Ansible版本：2.3.1.0

Python版本：2.7.5

命令：ansible-playbook -i清单/ DEV / playbooks / patching.yml -e“ ticketnum = 12345 perform_action = stop ansible_ssh_user = abc” -k

设置：

                             |____all

                                    |___ all.yml

剧本执行得很好，作为自动化的一部分，当从Python API [engine.py]调用剧本时，它无法获取group_vars和host_vars下定义的变量。

这是代码：

def runPlaybook(self, playbookYML, hostfile, remoteUser, remoteUserpwd, ticketnum, patchAction, envt):
    try:
        loader = Dataloader()
        inventory = Inventory(loader=loader, variable_manager=VariableManager(), host_list=hostfile)
        variable_manager = VariableManager()
        variable_manager.extra_vars = { 'ticketnum': ticketnum, 'perform_action': patchAction, 'ansible_ssh_user': remoteUser }
        options = namedtuple('Options', ['listtags','listtasks', 'listhosts', 'syntax', 'connection', 'module_path', 'fork', 'remote_user', 'ssh_common_args', 'ssh_extra_args', 'sftp_extra_args', 'scp_extra_args', 'verbosity', 'check', 'diff', 'become', 'become_method','become_user'])
        options = Options(listtags=False,listtasks=False, listhosts=False, syntax=False, connection='ssh', module_path=None, fork=100, remote_user=remoteUser, ssh_common_args=None, ssh_extra_args=None, sftp_extra_args=None, scp_extra_args=None, verbosity=None, check=False, diff=False, become=False, become_method=sudo,become_user=remoteUser)
        passwords = {'conn_pass': remoteUserPwd}
        pbex = PlaybookExecutor(playbook=[playbookYML], inventory=inventory, variable_manager=variable_manager, loader=loader, option=options, passwords=passwords)
        results = pbex.run
   except Exception as e:
       logger.error(traceback.print_exc())
       raise

上面的代码无法获取在清单/ [DEV或QA]下定义的group_vars和host_vars下定义的变量

请帮助我获取这些多阶段环境变量以进行加载。

Answer 1

我能够使用以下代码加载组变量。

cat db_details.csv | grep ',5,' | grep -v ',angel$' > /tmp/type1.csv
cat db_details.csv | egrep -i ',LifeLock,|gauto' | grep -i 'may' | grep -iv 'dec' >> /tmp/type2.csv

Answer 2

要访问Ansible库存文件中组中定义的主机的变量，您必须采用以下方式。

文件：inventory.ini

const data=[{"pcc":"1ADA","markets":{"origin":"ORG","destination":"DES"}},{"pcc":"1ADA","markets":{"origin":"ORD","destination":"DES"}},{"pcc":"1ADA","markets":{"origin":"ORG","destination":"DES"}},{"pcc":"1AZA","markets":{"origin":"ORG","destination":"DES"}},{"pcc":"1AXA","markets":{"origin":"ORG","destination":"DES"}}]

const resp = data.reduce((acc, ele) => {
    const ant = acc.find(x => x.pcc === ele.pcc);
    if(!ant) return acc.concat({pcc: ele.pcc, markets: [ele.markets]});
    ant.markets.push(ele.markets);
    return acc;
}, []);

console.log(resp);

文件：test.py

[all]
host_00 ansible_host=00.01.02.03 custom_variable=aaa
host_01 ansible_host=04.05.06.07 custom_variable=bbb
host_02 ansible_host=08.09.10.11 custom_variable=ccc
host_03 ansible_host=12.13.14.15 custom_variable=ddd
host_04 ansible_host=16.17.18.19 custom_variable=eee
host_05 ansible_host=20.21.22.23 custom_variable=fff
host_06 ansible_host=24.25.26.27 custom_variable=ggg

[group-one]
host_00
host_01

[group-two]
host_02
host_03
host_04

[group-three]
host_05
host_06

输出：

from ansible.parsing.dataloader import DataLoader
from ansible.inventory.manager import InventoryManager

# Set inventory filename.
inventoryFile = 'inventory.ini'

# Set groups of interest.
groups = ['group-one', 'group-three']

# Use ansible module for Python 3.
loader = DataLoader()
inventory = InventoryManager(loader=loader, sources=inventoryFile)

for group in groups:

    # Set hosts list.
    hostsList = inventory.groups[group].get_hosts()

    for host in hostsList:

        # If you want to print all host attributes you can do this:
        # print(host.__dict__)

        # Set some variables for each host from inventory.
        name            = host.name
        inGroups        = host.groups
        ansible_host    = host.vars['ansible_host']
        custom_variable = host.vars['custom_variable']

        print('name = {}, inGroups = {}, ansible_host = {}, custom_variable = {}'.format(name, inGroups, ansible_host, custom_variable))

我希望它能对您有所帮助。
