Question

我正在运行以下运行playbook的Python脚本：

#!/usr/bin/python

from __future__ import print_function

import json
import os
import ansible.inventory
import ansible.playbook
import ansible.runner
import ansible.constants
from ansible import utils
from ansible import callbacks

print('Loading function')

def run_playbook(**kwargs):

    stats = callbacks.AggregateStats()
    playbook_cb = callbacks.PlaybookCallbacks(verbose=utils.VERBOSITY)
    runner_cb = callbacks.PlaybookRunnerCallbacks(
        stats, verbose=utils.VERBOSITY)

    # use /tmp instead of $HOME
    ansible.constants.DEFAULT_REMOTE_TMP = '/test'

    out = ansible.playbook.PlayBook(
        callbacks=playbook_cb,
        runner_callbacks=runner_cb,
        stats=stats,
        **kwargs
    ).run()

    return out


def lambda_handler(event, context):
    return main()



def main():
    out = run_playbook(
        playbook='/test/little.yml',
    )
    return(out)


if __name__ == '__main__':
    main()

而且，这是我的ansible.cfg文件：

[ssh_connection]
ssh_args=-o ForwardAgent=yes
retries=2
sk_sudo_pass = yes

[defaults]
remote_user = root
host_key_checking = False
#remote_tmp     = tmp
local_tmp      = ~/tmp

当调用lambda函数时，我收到以下错误：

START RequestId: ccfe076e-0016-11e7-befa-7ba330223a64 Version: $LATEST
module initialization error: Unable to create local directories(/home/sbx_user1080/tmp): [Errno 30] Read-only file system: '/home/sbx_user1080'

END RequestId: ccfe076e-0016-11e7-befa-7ba330223a64

其中表示由于Lambda正在启动的容器中的权限问题，Ansible无法创建tmp文件。

那么，我该如何解决呢？此外，根据this discussion，Lambda支持将文件写入/ tmp目录。那么，如何将local_tmp设置为该目录？

Answer 1

您只能在AWS Lambda环境中写入/tmp。您无法在该环境中创建~/tmp目录。看起来你需要改变这个：

local_tmp = ~/tmp

到此：

local_tmp = /tmp

在AWS Lambda中运行Ansible时无法创建本地目录错误
