Clear Linux's Kent Helm was proud to announce the release and general availability of Intel Clear Containers 2.1.6, a maintenance update that promises to improve compatibility with recent Docker releases, but also adds various bug fixes.

In terms of compatibility, Intel Clear Containers 2.1.6 adds support for Docker 17.04.0-ce open-source container engine, which updates its development to be on par with the enterprise edition of Docker, as well as to lay the groundwork for Intel Clear Containers to become a plugin for Docker's enterprise edition.

Intel Clear Containers 2.1.6 also improves compatibility with the CRI-O (Container Runtime Interface) project and Kubernetes CRI by fixing pod containers' runtime list, the intra-pod containers volume support, the addition of CRI-O integration tests, as well as the ability to create cgroups for both containers and pods.

It adds support for OCI Runtime Specification 1.0.0 RC5, and requires at least Clear Linux containers image 14700 and the Clear Linux Containers kernel 4.9.24-60. Additionally, Intel Clear Containers 2.1.6 repairs the ability to run containers on CentOS systems, as well as failures when running cc-oci-runtime on Ubuntu.

Quality and documentation improvements

In terms of quality improvements, Intel Clear Containers 2.1.6 comes with multiple network, oci-config, and hypervisor tests, and there are a few documentation enhancements to make installing Intel Clear Containers on other GNU/Linux distributions a breeze.

New installation documentation is now available online for the Ubuntu, Fedora, Red Hat Enterprise Linux, CentOS, and, of course, Clear Linux operating systems. Metrics were added to CPU % consumption for network. Version 2.1.5 added network tests for nginx and ab, fixed creation of pods, and made it possible again to fetch the hostname of a replica in Swarm.
