  • Using the CRI-O Container Engine
  • OCI image format
  • OpenShift

Images

  • ubi8/rhel
  • ubi8/rhel-minimal
  • ubi8/rhel-init
  • ubi8/rhel-rsyslog
  • ubi8/support-tools
  • ubi8/net-snmp

Packages

Installed (or to install):

  • podman (manage containers)
  • buildah (build OCI-compliant container images)
  • skopeo (copy images to and from registries)

Dependencies:

  • runc (runtime client for OCI format containers)
  • containers-common
  • containernetworking-plugins
  • oci-systemd-hook
  • container-selinux

Concepts

OCI: Open Container Initiative

Container use cases:

  • single-node
  • multi-node (sometimes called “distributed systems”)

Commands that can operate without a container engine:

  • podman
  • buildah
  • skopeo
