Red Hat Enterprise Linux 7.8 Released

2 min read

Red Hat Enterprise Linux (RHEL) is a commercial Linux distribution with a history of more than ten years (initially released in 2000). It often uses on mainframes and supercomputers in addition to ordinary PCs and general servers. The excellent stability makes it widely used in many infrastructure-level servers. It provides support for multiple architectures such as the 64-bit ARM, x86/x86_64, Power PC, and IBM z Systems. Red Hat uses strict trademarked rules to limit the free redistribution of its officially supported version of RHEL, but RHEL’s source code still provided free of charge. Third-party derivative versions can be built upon the removal of non-free components such as Red Hat trademarks, such as community-supported commercial forks such as CentOS and Scientific Linux, as well as Oracle Linux.

The RHEL team announced the release of RHEL 7.8.

Changelog

  • Initial support for the CNI DNS plugin, which allows containers to resolve the IPs of other containers via DNS name, has been added.

  • Podman now supports anonymous named volumes, created by specifying only a destination to the -v flag to the podman create and podman run commands.

  • The podman info command, when run without root, now shows information on UID and GID mappings in the rootless user namespace.

  • Added podman build --squash-all flag, which squashes all layers (including those of the base image) into one layer.

  • The podman network createpodman network rmpodman network inspect, and podman network ls commands have been added to manage CNI networks used by Podman.

  • The podman volume create command can now create and mount volumes with options, allowing volumes backed by NFS, tmpfs, and many other filesystems.

  • Rootless Podman can experimentally squash all UIDs and GIDs in an image to a single UID and GID (which does not require use of the newuidmap and newgidmap executables) by passing --storage-opt ignore_chown_errors.

  • Rootless Podman containers with --privileged set will now mount in all host devices that the user can access.

  • Rootless Podman now supports health checks (#3523).
