Using Docker on CoreOS, I have a script which calls:
docker exec ...
This works fine on CoreOS, but I also want to test it on CircleCI. When I try to run that script on CircleCI, I get:
time="2015-06-22T01:14:51Z" level=fatal msg="Error response from daemon: Unsupported: Exec is not supported by the lxc driver" ./tests/run.sh returned exit code 1
Here are the test results on CircleCI.
I tried changing docker exec
to docker --exec-driver native exec
, however I am not entirely sure what a "driver" is, how to change it, or even if it's possible or desirable to do so.
What would be the best course of action around this error?
