arvados-docker-cleaner does not start on trusty (ubuntu 12.04).

this appears to be because one of its dependencies has a dependency that does not work with python 3.2 (which is the newest version of python3 on trusty).

docker-py seems to require idna, and the version we have is incompatible with the system python and results in a stack trace like this:

 python3 -m arvados_docker.cleaner --quota 250G

#1 Updated by Joshua Randall 9 months ago

My guess at a fix would be to pin the version of python3-docker-py built on trusty so that it uses an older version of idna (maybe that means installing idna separately and pinning that?)


#2 Updated by Joshua Randall 9 months ago

Actually it looks like python 3.4 is available on trusty but it isn't required by docker-py (which apparently should require python3 > 3.2).

#3 Updated by Joshua Randall 9 months ago

haha, right - I meant to say precise (12.04) on which the newest python is indeed 3.2 - ARGH!

#4 Updated by Joshua Randall 9 months ago

  • Subject changed from arvados-docker-cleaner broken on trusty to arvados-docker-cleaner broken on ubuntu precise (12.04)

#5 Updated by Joshua Randall 9 months ago

I've installed python 3.6 from source on all humgen-0x-0x nodes and arvados-docker-cleaner is now running out of a virtualenv, so our ~18TB of docker crap is now slowly being cleaned up and this is no longer an emergency for us
