Release 1.0.0

In release v1.0.0 of HyperContainer, we introduced several significant updates and fixed many bugs to make runV production ready. The featured updates include:

• runV Compatibility:
  • compatible with the most recent 1.0 of OCI runtime specification;
  • compatible with the latest CNCF containerd;
  • compatible with the latest Docker (17.06.1-ee and later).
• New hypervisor architectures support:
  • xenpv driver, with the latest Xen 4.9, we could launch runV with very minimal performance penalty (<5 % in most scenarios) on instance of Google GCE and other IaaS platform;
  • kvmtool driver brings the offical ARM support to runV.
• Feature update:
  • Pod level portmappings: allow configure port mappings in pod level, and dynamic update port mapping rules;
  • Read-only rootfs: allows runV to launch with read-only rootfs;
  • support vhostuser network card for qemu driver, which enables the low latency network for scenarios such as NFV.
• Many other feature or test improvements, and many bug fix.

Thanks the contribution from Huawei, ZJU, ARM, Intel, Alibaba, and other individuals.

Release 0.8.1

This is a bugfix release of 0.8:

• Enable vSock, a communication channel between host and guest.
• Kubernetes CRI compatibility issues.
• Container IO stream issues.
• Fixed the Xen build.

The detail of the issues addressed in 0.8.1 could be found here

And the binary packages for centos/rhel, fedora, debian, ubuntu could be find in the hypercontainer download page

Release 0.8.0

In this release, several significant updates are introduced, such as Kubernetes Container Runtime Interface (CRI) support, OCI images spec support:

• Feature: Kubernetes CRI support.
• Feature: OCI Image Spec support (hyperctl save -o nginx.tar -f oci ).
• Interfaces: better GRPC API support.
• Arch: support ARM64 CPUs with GIC version3, e.g. Cavium ThunderX 64-core CPU.
• Enhancement: move all the Pod level logic to hyperd, and runV only maintains the sandbox and containers.
• Enhancement: simplify the model and state machine -- one Pod is one VM.
• Enhancement: allow add/remove containers to/from a Pod/sandbox.
• Enhancement: do not stop sandbox without an explicit stop command even if the last container is stopped (To be compatible to Kubernetes CRI).

And many other improvements and updates.

The binaries for more distros could be download here.
