containerd了解 I recently had a need to manually load some container images into aLinuxsystem runningcontainerd(instead ofDocker) as the container runtime. I say “manually load some images” because this system was isolated from the Internet, and so simply running a container and havingcontainerd...
to run docker ps command again: kubernetes-node# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES You must see the empty output, that means Kuibernetes start using containerd instead of docker as a container runtime. Also, you can check this ...
有追求的工程师一般都是有技术洁癖的,云原生的世界更是如此,Kubernetes 虽然制定了容器运行时接口(CRI)标准,但早期能用的容器运行时只有 Docker,而 Docker 又不适配这个标准,于是给 Docker 开了后门,花了大量的精力去适配它。后来有了更多的容器运行时可以选择后,Kubernetes 就不得不重新考量要不要继续适配 Docker ...
The differences between Docker, containerd, CRI-O and runc Written by Tom Donohue Updated: 02 June 2021 Since Docker kicked off this explosion in containers, there’s been a growing family of tools and standards to help govern how to use this technology. Sadly, it’s all rather confusing ...
# result insteadofbuilding it again,so make sure you run the # following command first before building docker image # make ks-apiserver # COPY ks-apiserver/usr/local/bin/EXPOSE9090CMD["sh"] 构建镜像: 🐳 → cd build/ks-apiserver
nerdctl 只是 docker 的复制品? nerdctl 的目标并不是单纯地复制 docker 的功能,它还实现了很多 docker 不具备的功能,例如延迟拉取镜像(lazy-pulling)、镜像加密(imgcrypt)等。 延迟拉取镜像功能可以参考这篇文章:Containerd 使用 Stargz Snapshotter 延迟拉取镜像。

上面的配置方式是旧版 conainterd 采用的，已经 deprecated，改用新版配置方法解决了
CRI-O is an OCI-compatible lightweight implementation of the CRI. It was created as an alternative to Docker Engine. With CRI-O, you can start Kubernetes pods and pull necessary images. However, it is not a runtime. Instead, it is used to launch other low-level OCI-compatible runtimes,...
