I'm following the fig guide to using docker with a python application, but when docker gets up to the command
RUN pip install -r requirements.txt
I get the following error message:
Step 3 : RUN pip install -r requirements.txt ---> Running in fe0b84217ad1 Collecting blinker==1.3 (from -r requirements.txt (line 1)) Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProtocolError('Connection aborted.', gaierror(-2, 'Name or service not known'))': /simple/blinker/
This repeats several times and then I get another message:
Could not find any downloads that satisfy the requirement blinker==1.3 (from -r requirements.txt (line 1)) No distributions at all found for blinker==1.3 (from -r requirements.txt (line 1))
So for some reason pip can't access any packages from inside a docker container. Is there anything I need to do to allow it internet access?
However pip works fine to install things outside of the docker container, and worked fine even with that exact package (
blinker==1.3) so that's not the problem. Also this problem isn't specific to that package. I get the same issue with any
pip install command for any package.
Does anyone have any idea what's going on here?
