STANDARDS!

Areas to Standardize:

• Packaging

• Runtime

• Networking

Runtime - Specifications

OpenContainer Runtime-Spec (github.com/opencontainers/runtime-spec)

• June 2015

• Several Implementations, with runc as flagship

• Specification

• Currently v1.0.0-rc5

Network

Container Networking Interface

(CNI - github.com/containernetworking/cni)

• Used by RKT, kubernetes, OpenShift, Kurma, Cloud Foundry, RancherOS, usable with runC, and more

• Simple to integrate with a process based workflow

• December 2014

• Specification and Library

Packaging - Implied Standard

• Docker specific format

Docker Image

• Tight coupling with daemon version

• Signing requires Docker notary integration
• Image naming is Docker specific and bound to registries

Packaging - Specification

• April 2016

• Originated from Docker-1.10 and Registry v2 format

• Content addressibility

OpenContainer Image-Spec (github.com/opencontainers/image-spec)

• Signable. Possibility to have naming and discovery.

• Currenly releasing v1.0.0-rc5
• Gaining support from rkt, flatpak, skopeo, cri-o, docker, docker-registry and more

Cloud

Cloud Native Computing Foundation (https://cncf.io)

• Kubernetes orchestration
• Prometheus monitoring
• gRPC, CoreDNS, Linkerd, OpenTracing, Fluentd
• with containerd and rkt proposed
