27.3. New Features

  • Beginning RHEL Atomic Host 7.4.2, you can configure /var to be a mount point. This allows placing /var into a separate partition, which prevents other mount points from getting full if /var gets full. For more information and instructions, see Manual Partitioning.
  • The skopeo tool now by default requires a TLS connection. It fails when trying to use an unencrypted connection. To override the default and use an http registry, prepend http: to the <registry>/<image> string. For information on using skopeo, see Using skopeo to work with container registries.

  • The oci-umount package, which was previously shipped as a subpackage of docker, is now shipped separately.

    The oci-umount package provides an OCI hook program. If you add it to the runc JSON data file as a hook, runc will execute the application after the container process is created, but before it is executed, with a prestart flag. Docker adds the oci-umount as a container hook to the runc configuration when it is installed in the $HOOKSDIR directory. To modify the list of file systems to umount, edit the /etc/oci-umount.conf file.
