Presentation: Optimizing For Production Workloads
Share this on:
Abstract
Breaking down the containers runtimes into their base functionality and then building them up into a series or core libraries and tools to specialize in core capabilities. Our goal is, rather then have one monolithic daemon to do all container management, to build up a series of tools that specialize in each different function of container management.
The tooling landscape for containers is evolving rapidly--to keep things running smoothly in production, you need to keep your eye on the latest developments in container infrastructure. This talk will introduce the following:
- containers/Image: Library used by other tools for pulling and pushing container images to and from a container registry like docker.io and into other types of container storage
- containers/storage: Library used for storing container images on disk supporting multiple container backends including Overlay, Devicemapper, and Btrfs
- libpod : Library for managing the lifecycle of pods and containers
- Skopeo: CLI tool that uses containers/image and containers/storage to move container images between different types of containers storage, including container registries, container storage, Docker storage, OCI Directories etc. Think of it as scp for container images.
- Buildah: CLI tool that allows you to build OCI container images using standard linux tools, no daemon necessary, also has support for Dockerfile
- CRI-O : API server daemon for the Kubernetes Container Runtime Interface. optimized for serving the Kubernetes and OpenShift Workloads. Supports multiple container runtimes like runc and kata containers out of the box.
- Podman: Simple CLI tool used to create pods and containers without requiring a daemon.
Tools share the same container storage and infrastructure, allowing users to pick and choose the best tool for their workloads.
