Bug description:
I have been running the docker framework (2015-06-15 1.6.1.002) on a
Snappy Ubuntu Core (ubuntu-core/15.04/stable) instance on aws EC2. On
June 11th the instance automatically upgraded from ubuntu-core version
2 to ubuntu-core version 3 and rebooted. The running Docker
containers restarted without any issues, however when I next logged in
to run a docker command I got the following error:
FATA[0000] Get http:///var/run/docker.sock/v1.18/containers/json: dial
unix /var/run/docker.sock: permission denied. Are you trying to
connect to a TLS-enabled daemon without TLS?
I rebooted to see if it would help, but the error was still there. I
checked the dmesg log and found the following entry was added when I
tried to run a docker command:
[ 72.230872] audit: type=1400 audit(1434397079.776:12):
apparmor="DENIED" operation="connect" info="Failed name lookup -
disconnected path" error=-13 profile="docker_docker_1.6.1.002"
name="run/docker.sock" pid=1025 comm="docker.x86_64"
requested_mask="wr" denied_mask="wr" fsuid=1000 ouid=0
I tried using the docker command both as a nonprivileged user and
using "sudo". In both cases I was unable to run the docker command.
I was able to resolve the issue by uninstalling and reinstalling the
docker framework using the commands:
sudo snappy remove docker
sudo snappy install docker
