Ocado Technology Releases “Kubermesh”, a Prototype Self-Provisioning Mesh Network Kubernetes Cluster
The Ocado Technology team has created Kubermesh, a prototype “bare-metal, self-hosted, self-healing, self-provisioning, partial-mesh network Kubernetes cluster”. Kubermesh can essentially be seen as the glue joining several technologies together to form a container deployment platform consisting of an OSPF3 partial-mesh network and a iPXE-booted self-installing Kubernetes deployment.

Alternative Container Runtimes in Kubernetes
Recent changes in Kubernetes break its traditional tie-in to Docker and rkt as container runtimes. Kubernetes has released its Container Runtime Interface (CRI) API and there is a parallel ongoing implementation called CRI-O which attempts to create a bridge between Kubernetes and OCI-compliant runtimes, paving the way for Kubernetes to use any OCI compliant container runtime in a standard way.

Design for Continuous Evolution: Immutable Model Is Key for Robustness
At QCon New York, Eric Brewer described how advancing from continuous delivery to fast and stable continuous evolution requires a discrete construction step to define an immutable model of the system. Brewer’s compute infrastructure design team uses Helm to construct and safely validate new deployment models, prior to attempting real deployment, although the concepts are technology agnostic.
