Chapter 7. Notable changes to containers
A set of container images is available for Red Hat Enterprise Linux (RHEL) 8.1. Notable changes include:
Rootless containers are fully supported in RHEL 8.1.
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 more information:
The toolbox RPM package is fully supported in RHEL 8.1.
The toolbox command is a utility often used with container-oriented operating systems, such as Red Hat CoreOS. With toolbox, you can troubleshoot and debug host operating systems by launching a container that includes a large set of troubleshooting tools for you to use, without having to install those tools on the host system.
toolboxcommand starts a rhel-tools container that provides root access to the host, for fixing or otherwise working with that host.
For more information see Troubleshooting container hosts with toolbox.
- See the new documentation on Running containers with runlabels.
- The podman package has been upgraded to upstream version 1.4.2. For information on features added to podman since version 1.0.0, which was used in RHEL 8.0, refer to descriptions of the latest podman releases on Github.
