Trying to build a docker deployment using the examples, and I am getting the following error: Building dagster_daemon. Attempting this on a new AWS Workspace Linux desktop. Step 1/6 : FROM python:3.7 ---> ac9dead5ba6f Step 2/6 : RUN pip3 install dagster dagster-postgres dagit ---> Running in 8aff09a1c834 WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘NewConnectionError(‘<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7f2f0f8dbf50>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution’)’: /simple/dagster/

Hi Mark - I haven’t seen this issue before. Are you able to pip install other libraries in this environment? Based on the error message, my instinct is that this is likely an issue with Docker in general in this environment rather than something specific to Dagster.

Yes, I have been able to pip install other libraries and apps, and I was able to use Docker with other products as well. I will try again today with a more minimal approach. The repository I was trying is more of a full stack install.

Got it - yeah I'd be curious to know if it persists. Very strange!

I was able to do a standalone install and run the tutorial code, so it has something to do with the docker configuration.
