摘要

我想启动shell命令以异步方式构建docker镜像，构建成功但发生此错误：

    fatal: [192.168.0.1]: FAILED! => {"changed": false, "failed": true, "msg": "The async task did not return valid JSON: No JSON object could be decoded"}

重现步骤

我手动执行了python片段ansible执行：

/root/.ansible/tmp/ansible-tmp-1465081459.8-258691745536723/command
/root/.ansible/tmp/ansible-tmp-1465081459.8-258691745536723/arguments

结果是

    "end": "2016-06-05 07:12:38.323820",
    "stdout": "Sending build context to Docker daemon  12.8 kB\r\r

我执行的任务是

- name: build or check kafka docker image
  shell: docker build -t {{ image_name }} /tmp/dockerfile/kafka
  async: 2400                                     # wait seconds
  poll: 5                                        # poll wait seconds

我终于努力解决这个问题了。我添加了代码以在文件executor/task_executor.py下的第445行打印结果：

return dict(failed=True, msg=u"The async task did not return valid JSON: error:%s result:%s" % (to_unicode(e), result))

然后我发现了一些无效的json文本：/etc/profile.d/lang.sh: line 19: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory\\r\\n 在link的帮助下修复了这个语言环境问题后，这个问题就消失了。

异步任务未返回有效的JSON
