You should check your processor architecture using uname and adapt the source code to your architecture. I use a Raspberry Pi with armv6l processor architecture and Raspbian OS. Containerd on a Raspberry Pi Installation Dealing with an extra layer can bring more complexity that does not create more value. Nevertheless, a container orchestrator like kubernetesneeds only a container runtime to manage containers. dockerbrings a lot of user-experience features to make the interaction easier. In spite of this kuberneteschange, you can continue to use Docker in your CI/CD or for development purposes. The previous diagram looks like that now: Kubernetes without Docker The change will be effective in the v1.22 release. You will receive warnings if you still use dockerin this release. dockeritself calls containerd to manage the containers : Kubernetes with Dockerįrom v1.20 kubernetesdeprecates dockerin favor of runtimes using the Container Runtime Interface (CRI) such as containerdand cri-o. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc.” From Docker and Kubernetesīefore the 1.20 release, kuberneteswas using dockerto communicate with the containers. It is a runtime implementing the Container Runtime Interface (CRI) and presents interesting assets for hosted systems : “containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability.

runtime-spec defining how to run a container :.Two standards emerged from this initiative which constitutes the OCI model :
Docker company has been a major key player in its definition. In 2015 the Open Container Initiative ( OCI) was founded to create an application container standard. Having taken into account these feedbacks docker started cutting out the daemon and the CLI in docker. In parallel at that time, there were many criticisms made against the monolithic architecture of dockercontaining the CLI and the daemon. To remediate that, dockerstarted to implement libcontainers to launch containers without LXC.

Software architecture evolutionīased on LXC, dockerwas really dependent on its development. The dockerprowess was to create a standard software unit where the user can define images and launch them easily in containers. In its beginning, dockerwas using the LXC stack to isolate application resources. It provides an API to easily create and manage container application systems. Linux Containers ( LXC) was released in 2008 and relies on both previous kernel features.
