Chapter 2 Installing and Upgrading Oracle Container Runtime for Docker

This chapter describes the steps required to perform an installation or an upgrade of Oracle Container Runtime for Docker on an Oracle Linux 7 host.


Docker requires that you configure the system to use the Unbreakable Enterprise Kernel Release 4 (UEK R4) or later and boot the system with this kernel.

Using the Docker configuration files in /etc/sysconfig is deprecated. Instead, you should use the /etc/docker/daemon.json configuration file and systemd drop-in configuration files in /etc/systemd/system/docker.service.d as required.

After adding or modifying a drop-in file while the docker service is running, run the command systemctl daemon-reload to tell systemd to reload the configuration for the service.
