The Open Container Initiative (OCI), established in June 2015 by Docker and other industry leaders, is promoting common, minimal, open standards and specifications around container technology. Because of this, the OCI is helping to broaden the choices for open source engines. The initial specification effort from OCI is a runtime specification for containers. These specifications are followed by almost all major containerisation platforms. Native low-level runtimes include: At a high level, a container image is the build artifact that contains everything needed to run a piece of software. The bundle directory (using -b bundle) is optional. The OCI specifications provide the similar foundation for containers solutions going forward. After two years of work, the Open Container Initiative has published version 1.0 specifications for both a container image and a container runtime format. That's why the Open Container Initiative (OCI) has promoted a set of common, minimal, open standards and specifications around container technology, specifically the container format and runtime. For further advice or verification of your special transport requirements, please do not hesitate to contact your local Hapag-Lloyd … The Open Container Initiative (OCI) is a lightweight, open governance structure (project), formed under the auspices of the Linux Foundation, for the express purpose of creating open industry standards around container formats and runtime.

"Without this agreement, containers wouldn't be usable by enterprises." Azure Container Registry supports the OCI Distribution Specification, a vendor-neutral, cloud-agnostic spec to store, share, secure, and deploy container images and other content types (artifacts). The name must be unique on your container host. Anyone who wants to run this software then can specify some name, like example.com/my-app, to download, verify, and run that container. And, whether in a connected or disconnected environment, bundles can be validated both for identity and for the proper steps in an entire supply chain. OCI’s statement went on to say it expects to conclude version 1.0 of its container format specifications “in the next couple of months.” At that time, the organization’s Trademark Board will initiate a certification program for projects that include the OCI runtime (runc) and that follow the OCI container … A container's bundle is the directory with the container's OCI specification file, "config.json". The Open Container Initiative (OCI) is the governance which has been working with the industry to these standards. The Runtime Specification outlines how to run a “filesystem bundle” that is unpacked on disk. Open Container Initiative (OCI) Specifications (v1.0 and up) Support for Docker Image Manifest V2 Schema 2 provides the following functionality: The ability to use multiple tags per image. Unity Rules As OCI Launches 1.0 Container Spec. Image specification defines the archive format of OCI container images, which consists of a manifest, an image index, a set of filesystem layers, and a configuration. There are currently two specifications in development and in use: Runtime Specification (runtime-spec) and the Image Specification (image-spec). This topic describes the metrics emitted by Container Engine for Kubernetes in the oci_oke metric namespace. This week the Open Container Initiative (OCI) launched the Distribution Specification project to standardize container image distribution. A Linux Foundation project, OCI's purpose is to develop minimal common standards for software containers in an attempt to ensure that container solutions from all vendors are interoperable.. Since runc is the reference implementation of the OCI runtime specification, it can not really experiment with new features, as we saw with cgroups v2. Earlier today, the Open Container Initiative (OCI) released v1.0 of their container runtime and container image specifications. The specifications serve to standardize basic components of containers, ensuring compatibility and interoperability, and allowing a variety of tools to interface with compliant containers.
