Today we’re releasing version 2.1 of the Red Hat Container Development Kit. With the CDK, developers can easily create enterprise-ready containerized applications which target both OpenShift 3 development and Red Hat Enterprise Linux environments. Enjoy the ease and experience of developing this type of solution locally, on your own machine, without sacrifice or compromise.
Here are the key features in the CDK 2.1 release:
- OpenShift upgraded to OpenShift Enterprise 3.2. See here to find out more about the new features in OpenShift Enterprise 3.2.
- Hyper-V support (native hypervisor for Windows) — Technology preview
- Reduced size of the CDK Vagrant box by ~150MB
- Ability to persist data within the VM using persistent volume claims. The CDK 2.1 allows the user to make use of persistent volumes in order to persist data between restarts of pods, OpenShift or even the whole VM.
- OpenShift registry exposed as route
- There are also several bug fixes done as part of CDK 2.1 release.
