5.3. New Features

  • Rootless containers are now fully supported

    Rootless containers are containers that are created and managed by regular system users without administrative permissions. This allows users to maintain their identity, including such things as credentials to container registries.

    You can try rootless containers using the podman and buildah commands. For further information:

  • fuse-overlayfs now available, might require changes to rootless containers

    The fuse-overlayfs package provides an overlayfs FUSE implementation, which can be used in rootless containers. With FUSE, it is possible to implement a fully functional file system in a user-space program.

    Due to the changes in storage, you might need to modify your rootless containers when upgrading to RHEL Atomic Host 7.8.0.

  • The quay registry is not searched by default anymore

    Previously, using short image names sometimes pulled incorrect images. To fix this, the quay.io registry has been removed from the default registry search list in /etc/containers/registries.conf.

    Now you need to specify the full repository name when pulling an image, for example quay.io/myorg/myimage.
