27.3. New Features
-
Beginning RHEL Atomic Host 7.4.2, you can configure
/varto be a mount point. This allows placing/varinto a separate partition, which prevents other mount points from getting full if/vargets 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
prestartflag. Docker adds the oci-umount as a container hook to the runc configuration when it is installed in the$HOOKSDIRdirectory. To modify the list of file systems to umount, edit the /etc/oci-umount.conf file.
