# man docker-run
# When using SELinux, mounted directories may not be accessible
# to the container. To work around this, with Docker prior to 1.7
# one needs to run the "chcon -Rt svirt_sandbox_file_t" command on
# the directories. With Docker 1.7 and later the z mount option
# does this automatically.
# Since Docker 1.7 was release 5 years ago we only support 1.7 and newer.
