Dockerfile update is triggering a 'Temporary failure in name resolution' error

If you are making changes to your Dockerfile and consistently see an error that states "Temporary failure in name resolution", please reach out to your local administrator or Domino support team. 

[91m WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, 
status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.
connection.VerifiedHTTPSConnection object at 0x7f0c917fd6a0>: Failed to establish a 
new connection: [Errno -3] Temporary failure in name resolution',)': /simple/psycopg2

If your deployment is managed by Domino we should be able to help fix the issue. If you have a customer-managed deployment (on-prem, etc.), your local IT team will need to investigate network routing on the build node and perhaps launch a new one. In almost all cases, this is not an error that users will be able to resolve on their own.
