New submission from Mika Fischer <fisc...@videmo.de>:
Inside a windows docker container, SSL verification fails for some but not all hosts. See this issue over in the docker repo: https://github.com/docker-library/python/issues/359 Maybe you guys could shed some light on what could be the possible. To reproduce, install Docker for Windows and then: This works: ``` docker run -ti python:3.7-windowsservercore-1809 python -c "import urllib.request as r; r.urlopen('https://bootstrap.pypa.io').close()" ``` This doesn't ``` docker run -ti python:3.7-windowsservercore-1809 python -c "import urllib.request as r; r.urlopen('https://google.com').close()" Traceback (most recent call last): File "C:\Python\lib\urllib\request.py", line 1317, in do_open encode_chunked=req.has_header('Transfer-encoding')) File "C:\Python\lib\http\client.py", line 1229, in request self._send_request(method, url, body, headers, encode_chunked) File "C:\Python\lib\http\client.py", line 1275, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "C:\Python\lib\http\client.py", line 1224, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "C:\Python\lib\http\client.py", line 1016, in _send_output self.send(msg) File "C:\Python\lib\http\client.py", line 956, in send self.connect() File "C:\Python\lib\http\client.py", line 1392, in connect server_hostname=server_hostname) File "C:\Python\lib\ssl.py", line 412, in wrap_socket session=session File "C:\Python\lib\ssl.py", line 853, in _create self.do_handshake() File "C:\Python\lib\ssl.py", line 1117, in do_handshake self._sslobj.do_handshake() ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Python\lib\urllib\request.py", line 222, in urlopen return opener.open(url, data, timeout) File "C:\Python\lib\urllib\request.py", line 525, in open response = self._open(req, data) File "C:\Python\lib\urllib\request.py", line 543, in _open '_open', req) File "C:\Python\lib\urllib\request.py", line 503, in _call_chain result = func(*args) File "C:\Python\lib\urllib\request.py", line 1360, in https_open context=self._context, check_hostname=self._check_hostname) File "C:\Python\lib\urllib\request.py", line 1319, in do_open raise URLError(err) urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)> ``` ---------- assignee: christian.heimes components: SSL messages: 336761 nosy: Mika Fischer, christian.heimes priority: normal severity: normal status: open title: SSL verification fails for some sites inside windows docker container type: behavior versions: Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36137> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
