提取模块返回“无法计算远程文件的校验和".在Docker中运行时，但不在Docker中时运行良好 [英] Fetch module returns "unable to calculate the checksum of the remote file" while running in Docker but works fine when not in Docker

问题描述

Ansible剧本(copy_file.yml):

Ansible playbook (copy_file.yml):

- name: Copy this file over please
  hosts: all
  gather_facts: false
  tasks:
    - name: Get files from scanners running in each DC
      fetch:
        src: /tmp/file_to_copy
        dest: /tmp/local_place
        flat: yes
        fail_on_missing: yes
        validate_checksum: no

命令:ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook -i inventory playbook/copy_file.yml

当我运行它时它可以工作.

It works when I run it.

但是当我对其进行docker化时，它会给我带来错误:

But when I dockerize it, it gives me the error:

fatal: [remotehost.com]: FAILED! => {"changed": false, "file": "/tmp/file_to_copy", "msg": "unable to calculate the checksum of the remote file"}

我的dockerfile非常简单.它只是复制一个包含ansible命令的脚本并运行它.其基本图像为Alpine Linux.
Dockerfile :

My dockerfile is very simple. It just copies a script that contains the ansible command and runs it. Its base image is Alpine Linux.
Dockerfile:

FROM some_url/alpine/python:3.7-alpine

RUN apk add --no-cache musl-dev libffi-dev openssl-dev
RUN apk add build-base
RUN apk add bash

COPY / /

RUN pip install -r requirements.txt

ENTRYPOINT ["/run.sh"]

Ansible版本:ansible 2.9.2

Ansible version: ansible 2.9.2

推荐答案

Q:*致命:... {" file:"/tmp/file_to_copy，" msg:"无法计算远程文件的校验和"}

Q: *"fatal: ... {"file": "/tmp/file_to_copy", "msg": "unable to calculate the checksum of the remote file"}

A:尝试找出为什么状态返回checksum: 0.例如

A: Try to find out why stat returns checksum: 0. For example

- hosts: remotehost.com
  tasks:
    - stat:
        path: /tmp/file_to_copy
      register: result
    - debug:
        var: result.stat.checksum

Notes

• 请参见无法计算远程文件的校验和.壳是重击. ansible ver 2.0.2.0#29769

当校验和为0时报告错误.请参见 lib/ansible/plugins/action/fetch.py​​

The error is reported when the checksum is 0. See lib/ansible/plugins/action/fetch.py

if remote_checksum == '0':
    result['msg'] = "unable to calculate the checksum of the remote file"

• 请参见 lib/ansible/plugins/操作/初始化 .py
• See lib/ansible/plugins/action/init.py

def _remote_checksum(self, path, all_vars, follow=False):
    ...
    x = "0"  # unknown error has occurred
    try:
        remote_stat = self._execute_remote_stat(path, all_vars, follow=follow)
        ...
            x = remote_stat['checksum']  # if 1, file is missing
        ...
        return x  # pylint: disable=lost-exception

def _execute_remote_stat(self, path, all_vars, follow, tmp=None, checksum=True):
...
    mystat = self._execute_module(module_name='stat', module_args=module_args, task_vars=a

    ...
    return mystat['stat']
