从Mac Docker容器中的botocore.exceptions.EndpointConnectionError
当我试图从在Mac上运行的Docker容器内联系DynamoDB时，我最近开始得到一个EndpointConnectionError（超时后）。 相同的代码和安装程序以前工作正常。
以下是一些示例代码：
>>> from boto3 import resource >>> r = resource('dynamodb') >>> table = r.Table('Users') >>> table.put_item(Item={'id':'987987'}) 我的〜/ .aws / config：
[default] output = json region = us-east-1
我正在使用的代码重build和重新启动容器（从Mac OS）：
#!/bin/sh docker-machine ssh default "docker ps | awk 'NR > 1 {print \$1}' | xargs --no-run-if-empty docker kill" docker build -t <image_name> . docker-machine ssh default "docker run -p 80:80 -v /var/datenight_secret:/var/www/.aws <image_name>" &

当我尝试我们东 – 2或欧 – 西1时，我得到相同的行为（挂起很长时间，然后相同的堆栈跟踪）。 相同的configuration和凭证文件在us-east-1 EC2主机上或从我的Mac OS上正常工作。
基于这个问题，我确保HTTP_PROXY和HTTPS_PROXY都是空白的。
Python版本是Python 3.4.3。
运行docker-machine stop default; docker-machine start default docker-machine stop default; docker-machine start default解决了这个问题。 多么深刻的不满意 – 我认为这将是一个有趣的问题，会教我一些关于networking的事情。
