dockerfile - Getting an "operation not supported" error when trying to RUN something while building a docker image -
i'm trying build docker image following command:
docker build -f conf/dockerfile -t my_app_name . the dockerfile starts with:
from ubuntu:14.04 copy conf/pubkey pubkey run echo 'deb http://downloads.skewed.de/apt/trusty trusty universe' >> /etc/apt/sources.list \ && apt-key add pubkey \ && rm pubkey and returns info[0000] operation not supported.
regardless of put after run (even run echo 1 fails)
i tried running shell in intermediate docker image (docker run a7bb092… -it /bin/sh) throws fata[0000] error response daemon: cannot start container a7bb092…: operation not supported
how can fix this?
well, turns out if machine had kernel update didn't restart yet docker freaks out. restarting machine fixed that. oops.
