Clear Containers 3.0.0-alpha.2

by Samuel Ortiz

Hi, We just released Clear Containers 3.0.0-alpha.2 and virtcontainers 1.0.0-rc.2. The virtcontainers, runtime, proxy and shim repos have been tagged accordingly. Highlights for this release: - CRI-O and Kubernetes fix. There still is a networking issue we're working on, but one can now start a Kubernetes cluster on top of CRI-O and Clear Containers 3.0. - Clear Containers 3.0 installation documentation - New cc-env cli command for dumping configuration details - Runtime test coverage bumped to 50% - Proxy support for forwarding hyperstart reponse data back to clients. Cheers, Samuel. --------------------------------------------------------------------- Intel Corporation SAS (French simplified joint stock company) Registered headquarters: "Les Montalets"- 2, rue de Paris, 92196 Meudon Cedex, France Registration Number: 302 456 199 R.C.S.

Release 2.2.0

by Venegas Munoz, Jose Carlos

# Release 2.2.0 https://github.com/01org/cc-oci-runtime/releases/tag/2.2.0 This major release of the cc-oci-runtime introduces a major change: Use the Device Mapper* volumes as VM disks: Now, when a container’s root filesystem is a Device Mapper volume mount point, the cc-oci-runtime will use the volume as a VM disk. When the rootfs is not a Device Mapper volume, the cc-oci-runtime still uses 9pfs to mount the container root filesystem in our secure VM. Using a Device Mapper volume as a disk provides a better I/O performance and better support for POSIX file operations. When you configure Docker* to use a Device Mapper storage driver[1], `dnf install` will work again. You can verify if Docker is using a Device Mapper storage driver with the following command: docker info|grep 'Storage Driver' Note: If you are using Fedora*, the Device Mapper is already the default and you should get immediate benefits. ## Changes - cc-oci-runtime.sh: Enable debug by default. - configure: Add warning when kernel or image is not found. - proxy: Better error message for too long socket path. - metrics: Formalized the metrics reporting methods. - build: Add option to install kernel and image. # Installation - CentOS: https://github.com/01org/cc-oci-runtime/blob/master/documenta tion/Installing-Clear-Containers-on-Centos-7.md - Ubuntu: https://github.com/01org/cc-oci-runtime/blob/master/documenta tion/Installing-Clear-Containers-on-Ubuntu.md - Fedora: https://github.com/01org/cc-oci-runtime/blob/master/documenta tion/Installing-Clear-Containers-on-Fedora.md - Clearlinux: https://github.com/01org/cc-oci-runtime/blob/master/docum entation/Installing-Clear-Containers-on-ClearLinux.md [1] https://docs.docker.com/engine/userguide/storagedriver/device-mappe r-driver/
