Discussion of "Building, running, and managing containers"

Look into:

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

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

Installed (or to install):

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

Dependencies:

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

OCI: Open Container Initiative

Container use cases:

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

Core technologies:

• cgroups
• namespaces
• SELinux

Commands that can operate without a container engine:

• podman
• buildah
• skopeo
• runc
