汇总一些容易混淆的容器领域技术概念，希望对你有所帮助。
技术栈架构
生态对比
| Ecosystem | Orchestration Service | Orchestration Agent | Container Engine | Container Runtime | CLI tools |
|---|---|---|---|---|---|
| OCI / CNCF | k8s | kubelet | containerd (CRI runtimes) | runc / kata (OCI runtimes) | ctr, crictl |
| Docker | docker swarm | dockerd (docker CLI) | containerd | runc | docker |
| LXD / Canonical | clusterd lxd | lxd | lxd | lxc | lxc |
| OpenShift / Redhat | k8s | kubelet | CRI-O | runc | podman |
当然，这里列出的只是各个生态的默认技术栈，开源社区中还有各种项目让不同生态的组件互相组合协同工作。比如：
Mirantis/cri-dockerd: dockerd as a compliant Container Runtime Interface for Kubernetes (github.com)
automaticserver/lxe: Kubernetes CRI shim for lxd. Initially contributed by Automatic Server AG (http://www.automatic-server.com) (github.com)
