Report for 2018-03-01 to 2018-03-31

This report covers the development in the linuxkit/linuxkit linuxkit/lcow linuxkit/kubernetes linuxkit/virtsock linuxkit/rtf linuxkit/homebrew-linuxkit moby/tool repositories. There were 170 contributions (PRs/Issues/Comments) from 25 individual contributors. 38 new PRs were opened and 41 PRs were merged. 13 new issues were opened and 10 issues were closed.

In March we added initial support for s390x as the third architecture to LinuxKit.

There have been the regular updates to the kernels. The latest supported kernels are 4.15.14/4.14.31/4.14.29-rt/4.9.91/4.4.125. We reduced the number of supported kernels for non-x86_64 architectures, primarily to cut down the kernel compile times on the servers available. On arm64 we now only support the 4.15.x, 4.14.x, and 4.14.x-rt kernels while for s390x we support 4.15.x and 4.14.x. The kernel configuration tests have been extended to also work on arm64. We also enabled support for CEPH in the kernels.

On the tooling side, we added support for qcow2 EFI images and enabled logging for onboot containers to /var/log for easier debugging.

We updated Kubernetes to 1.9.6, WireGuard to 0.0.20180304, and notary to 0.6.0 (which should also remove the certificate expiry warnings).

For the Linux Container on Windows (LCOW) subproject, we again significantly increased the test suite, primarily around volume sharing.
