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:
- for rootless containers, see How does rootless Podman work.
- for buildah, see Building container images with Buildah.
- for podman, see Building, running, and managing containers.
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
.
