Possible solution:
It seems that you are encountering a connectivity issue when running an Azure CLI command in your QA environment. The error message you received is: ERROR: <urllib3.connection.HTTPSConnection object at 0x7ff24b791100>: Failed to establish a new connection: [Errno -2] Name or service not known.

A similar issue was reported before, where the user encountered an error message: <urllib3.connection.HTTPSConnection object at 0x7f3ed60e6490>: Failed to establish a new connection: [Errno -2] Name does not resolve when trying to log in with Azure CLI inside of a container.

The solution provided in the previous issue was to test if the container can resolve login.microsoftonline.com by running the following commands:

apt-get update
apt install dnsutils
nslookup login.microsoftonline.com

You can try running these commands in your QA environment to see if the container can resolve the domain name. If the result is similar to the one provided in the previous issue, then the issue might be related to the DNS resolution in your environment.
