Description of problem:
$ sudo dnf update
SELinux is preventing ruby from 'execute' accesses on the file conftest.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that ruby should be allowed execute access on the conftest 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:
# ausearch -c 'ruby' --raw | audit2allow -M my-ruby
# semodule -X 300 -i my-ruby.pp

Comment 1 Daniel Walsh 2016-09-12 16:18:19 UTC
This looks like you are volume mounting conftest from a home directory into a docker container.  If you want to have this content accessible and writable by the container you should use :Z or :z on the volume mount command.
