Description of problem:
Since the most recent docker and docker-selinux updates:

docker-1.8.2-1.gitf1db8f2.fc22.x86_64
docker-selinux-1.8.2-1.gitf1db8f2.fc22.x86_64

When I go to rebuild some of my docker containers, I get an error similar to this for what looks like any RUN line in my Dockerfile.  I'm running SELinux in enforcing mode and using the overlayfs storage driver for Docker.  Before the upgrades above, this setup was able to generate containers without issues.

If I disable SELinux, containers build fine.

SELinux is preventing exe from 'entrypoint' accesses on the file /bin/dash.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/bin/dash default label should be shell_exec_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /bin/dash

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that exe should be allowed entrypoint access on the dash file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep exe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
