New features

Rootless containers are now generally available and fully supported in RHEL Server and RHEL Workstation. In addition to this, this latest release has major updates to container tools: Podman 1.6.4, Buildah 1.11.6 and Skopeo 0.1.41. Another important change is the updated container images. Here are some of the new features:

  • 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 create, podman network rm, podman 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).
