获取模块返回“无法计算远程文件的校验和"；在 Docker 中运行时，但不在 Docker 中时工作正常 [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 playbook (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

它在我运行时有效.

但是当我对它进行 dockerize 时，它​​给了我错误:

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.它的基础镜像是 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: *"fatal: ... {"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:试着找出为什么 stat 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

• 见无法计算远程文件的校验和.壳牌是bash.ansible 版本 2.0.2.0 #29769

校验和为0时报错.见lib/ansible/plugins/action/fetch.py​​

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

• 参见 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
ll_vars, wrap_async=False)
    ...
    return mystat['stat']
