Logging into GCP SQL: How to Ensure PromptSession Is Imported or Otherwise Resolve

问题

I am trying to use the Cloud Shell to update some user permissions. I am logging in using gcloud sql connect my-instance --user=root

gcloud sql connect my-instance
Whitelisting your IP for incoming connection for 5 minutes...done.
Connecting to database with SQL user [sqlserver].********************************************************************************
Python command will soon point to Python v3.7.3.
Python 2 will be sunsetting on January 1, 2020.
See http://https://www.python.org/doc/sunset-python-2/
Until then, you can continue using Python 2 at /usr/bin/python2, but soon
/usr/bin/python symlink will point to /usr/local/bin/python3.
To suppress this warning, create an empty ~/.cloudshell/no-python-warning file.
The command will automatically proceed in  seconds or on any key.

A) I have made the root user's password so insecure and easy there is no way I am mistyping it.

B) It is the third of January, so I really don't know what this Python version error is on about. I made the file but FYI ~/.cloudshell did not exist so I had to make it first. Even so, it just suppresses the version warning, the main error persists when I try to log in.

The documentation acknowledges there are a couple other login methods using glcoud beta sql connect, but that gets me another error

2020/01/04 18:38:41 Rlimits for file descriptors set to {&{8500 1048576}}
2020/01/04 18:38:41 invalid json file "/tmp/tmp.s38C662KKr/legacy_credentials/me@gmail.com/adc.json": open /tmp/tmp.s38C662KKr/legacy_credentials/me@gmail.com/adc.json: no such file or directory
ERROR: (gcloud.beta.sql.connect) Failed to start the Cloud SQL Proxy.

Same for alpha.

This is the first thing I have typed into Cloud Shell, so I can't imagine what could have broken PromptSession.

How can I resolve this error and log into SQL Server using Cloud Shell?

回答1:

There most likely is an issue while attempting to connect from the Cloud Shell (I managed to connect from a Compute Engine instance with this command); possibly related to the Python run-time / environment variable. It has been reported here. Engineering is aware and are looking into it.
