Container Runtime and Image Format Standards - What it Means to be “OCI-Certified” [I] - Jeff Borek, IBM & Stephen Walli, Microsoft
With the proliferation and rapid growth of container-based solutions over the past few years— including container-based solutions from almost all major IT vendors, cloud providers, and emerging start-ups—the industry needed a standard on which to support container image formats and runtimes while also ensuring interoperability and neutrality. The Open Container Initiative (OCI) was launched with the goal of developing common, minimal, open standards and specifications around container technology without the fear of lock-in. OCI has recently issued v1.0 of its container image format and runtime specifications, which enable a consistent and stable platform for running containerized applications.

The next phase in ensuring broad adoption of common container image format and runtime specifications is the OCI Certification program, which will be launching soon. This session will provide an overview and goals of the program, factors to consider if becoming OCI-certified makes sense for your container project, how to get your container project OCI-certified, and how you might be able to gain interoperability benefits from OCI-certified solutions. This session will also include a demo of the OCI Image validator being run against container images from container image registries from multiple vendors.

Embedding the Containerd Runtime for Fun and Profit [I] - Phil Estes, IBM
The containerd project, one of the youngest in CNCF, is purpose-built to be an embeddable container runtime expected for use within higher layer container systems like the Docker engine and the Kubernetes orchestrator. Of course, the intent is that it will be used and embedded within a variety of software systems and has been designed for easy consumption via a gRPC API and client library.

In this talk we'll walk through a straightforward example of building up a container "client" written in Go, using today's containerd client library and API. Similar to how the Kubernetes CRI uses the containerd endpoints or how the Docker engine's libcontainerd operates, our small client will have access to all the same capabilities of container lifecycle management and registry interactions provided by containerd.

To finish our tour of building a fully functioning containerd client, we will pair our new sample application with LinuxKit and the Moby tool project. Using these tools, we'll build a simple virtual machine that embeds containerd and our sample client to test interesting aspects of containerd's capabilities in our own customized Linux OS image.

Kata Containers: Hypervisor-Based Container Runtime - Xu Wang, HyperHQ & Samuel Ortiz, Intel

Kata Containers is a merge of 2 hypervisor based container runtime efforts: Hyper's runV and Intel's Clear Containers. With Kata Containers, each container is hypervisor isolated just like an EC2 or GCE instance. It is an OCI compatible runtime and as such can seamlessly work with containerd or hyperd. Moreover it fully supports the Kubernetes CRI APIs and thus can run and manage hypervisor isolated Kubernetes pods through CRI-O, containerd-cri or frakti. Finally, Kata Containers is a multi architecture project as it supports x86, ARM, Power and s390x platforms.

During this talk we will describe the Kata Containers architecture and how it drastically reduces the virtualization overhead in order to be as fast as a namepace based container runtime while being as secure as a legacy VM. We will also run a multi tenant Kubernetes demo in order to show how Kata Containers could become the cornerstone of a secure, infrastructure free, container cloud.

Building Specialized Container-Based Systems with Moby: A Few Use Cases [I] - Patrick Chanezon, Docker
Moby is an open source project providing a "LEGO set" of dozens of components, the framework to assemble them into specialized container-based systems, and a place for all container enthusiasts to experiment and exchange ideas.
One of these assemblies is Docker CE, an open source product that lets you build, ship, and run containers.

This talk will explain how you can leverage the Moby project to assemble your own specialized container-based system, whether for IoT, cloud or bare metal scenarios.
We will cover Moby itself, the framework, and tooling around the project, as well as many of it’s components: LinuxKit, InfraKit, containerd, SwarmKit, Notary.
Then we will present a few use cases and demos of how different companies have leveraged Moby and some of the Moby components to create their own container-based systems.

CRI-O: All the Runtime Kubernetes Needs, and Nothing More - Mrunal Patel, Red Hat
CRI-O is a brand new container runtime dedicated and optimized to support kubernetes workload. Its goal is to be a stable container runtime tied to kubernetes releases, replacing the docker daemon.

Historically every update of Docker has broken Kubernetes. This has led to major rewriting and fixes of Kubernetes, which is understandable since Docker is not primarily for Kubernetes. Kubernetes needs a container runtime dedicated to its specifications.

CRI-O, the name comes from the Container Runtime Interface for Open container runtimes, takes advantages of emerging standards like OCI Runtime and Image Specification, as well as open source projects to handle container images (github.com:containers/image, github.com:containers/storage) . This means as these projects advance CRI-O will be able to take advantage of the improvements and features, but all the while guaranteeing that it will not break any functionality required by the Kubernetes CRI. CRI-O works with runc and Clear Containers runtimes.

CRI-O was designed from the ground up to satisfy Kubernetes Container Runtime Interface, and currently passes all node and E2E tests. The github repository has been setup to not accept any pull requests that causes these tests to break. We will be tying the versions of CRI-O to the Kubernetes versions, to maintain complete compatibility.

This talk will describe the CRI-O architecture as well as demonstrate different kubernetes features running on top of CRI-O exercising the CRI API. The attendees will learn how to configure CRI-O with kubernetes and use it for their workloads.

Building Better Containers: A Survey of Container Build Tools [I] - Michael Ducy, Chef
If you stick to the “industry standard” method of building containers (Dockerfiles), it’s easy to build containers that contain libraries, tools, binaries, and more that you don’t need. One survey showed that over 75% of containers contain a full Operating Systems. So how can you build containers that only contain the bits you require to run a particular application, and nothing more. This talk will cover various tools in the open source community that provide better methods for building containers, no matter the underlying container runtime. We will explore Bazel (along with Distroless), Smith (from Oracle), and Habitat (from Chef), and we will cover the benefits and drawbacks of each method. A short demo of each tool will be included.
