Chapter 2. Changes and improvements

This section highlights some of the notable changes introduced in CodeReady Containers 1.2.

2.1. New features

  • CodeReady Containers brings a minimal, preconfigured OpenShift Container Platform 4.2 cluster to your local laptop or desktop computer for development and testing purposes. CodeReady Containers is delivered as a Red Hat Enterprise Linux virtual machine that supports native hypervisors for Linux, macOS, and Microsoft Windows 10.

    • CodeReady Containers is designed for local development and testing on an OpenShift 4 cluster. To run an OpenShift 3 cluster locally, see Red Hat Container Development Kit.
  • Certificates are now automatically recovered once they have expired. The certificate recovery process adds approximately three minutes to the virtual machine start time.

2.1.1. Technology Previews

Support for these features falls under the Technology Preview Features Support Scope.

  • On Windows 10, an alternative network for Hyper-V can now be used. Create a virtual switch named crc to connect to an alternative network segment or network adapter (provided that there is a DHCP server on this network).

2.1.2. Usability improvements

  • macOS now gets a fixed IP address. As a result, network restarts are less frequent.

2.2. Notable changes

  • Support for the VirtualBox hypervisor has been deprecated and will be removed in the next release.
