This Week in Enhancements - 2022-07-22

Updates since 2022-07-15

Enhancements for Release Priorities

Prioritized New Changes

<PR ID>: (activity this week / total activity) summary

There was 1 Prioritized New pull request:

  • 1193: (57/57) microshift: USHIFT-40 Default CNI for MicroShift (mangelajo) (USHIFT-40)

    priority/important-soon

    This enhancement proposes the adoption of a default MicroShift CNI.

    MicroShift addresses customer use cases with low-resource, field-deployed edge devices (SBCs, SoCs) requiring a minimal K8s container orchestration layer.

    MicroShift is targeting a class of devices like Xilinx ZYNQ UltraScale+, fitlet2, NVIDIA Jetson TX2, or Intel NUCs that are pervasive in edge deployments. These cost a few hundred USD, have all necessary accelerators and I/O on-board, but are typically not extensible and are highly constrained on every resource, e.g.:

    • CPU: ARM Cortex-A35-class or Intel Atom class CPU, 2-4 cores, 1.5GHz clock
    • memory: 2-16GB RAM
    • storage: e.g. SATA3 @ 6Gb/s, 10kIOPS, 1ms (vs. NVMe @ 32Gb/s, 500kIOPS, 10µs)
    • network: Less bandwidth and less reliable than data center-based servers, including being completely disconnected for extended periods. Likely 1Gb/s NICs, potentially even LTE/4G connections at 5-10Mbps, instead of 10/25/40Gb/s NICs

Prioritized Active Changes

There was 1 Prioritized Active pull request:

  • 1187: (107/177) microshift: kubernetes for device edge (dhellmann) (OCPPLAN-9080) (USHIFT-50)

    lgtm, priority/important-soon

    This enhancement describes MicroShift, which provides an essential container orchestration runtime compatible with Kubernetes and OpenShift built for Internet-of-things (IoT) and Edge computing scenarios that are constrained in CPU, memory, and network bandwidth. The container orchestration runtime is binary compatible with OpenShift Container Platform, but it is not 100% API resource compatible. It has a strict subset of OpenShift API resources pertinent for IoT and Edge computing scenarios with a strong bias to retaining traditional runtime security controls like SecurityContextConstraints and SELinux.

  • 1014: (107/600) multi-arch: Heterogeneous architecture clusters (Prashanth684) (RFE-2240) (OCPPLAN-4577)

    This enhancement describes the plan to support provisioning and upgrades of heterogeneous architecture Openshift clusters. A heterogeneous cluster is a cluster with nodes running on different architectures with a homogeneous control plane and worker machinesets supporting any combination of architectures (eg: x86 control plane + a mix of ARM/P/Z worker nodes). This document describes the support needed for heterogeneous architecture clusters in phases. There will be three major phases with basic support in phase 1 which is targeted for a 4.11 techpreview (with documented limitations) and the other phases which address gaps beyond the 4.11 time frame. The targeted platform for the initial phase is Azure with support for x86 and ARM architectures.
