Description of problem:
SELinux is preventing portainer from 'connectto' accesses on the unix_stream_socket /run/docker.sock.

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

If você acredita que o portainer deva ser permitido acesso de connectto em docker.sock unix_stream_socket  por default.
Then você deve informar que este é um erro.
Você pode gerar um módulo de política local para permitir este acesso.
allow this access for now by executing:
# ausearch -c 'portainer' --raw | audit2allow -M my-portainer
# semodule -X 300 -i my-portainer.pp

Comment 1 Daniel Walsh 2017-09-22 10:52:52 UTC
You are running a confined container and giving it access to the docker.sock. Which SELinux is correctly blocking. Any process that can talk to the docker.sock, owns your system.  So you might as well run with --privileged mode.  If this is your intention.  If not, then you have a container breakout...
