Docker vs containerd

Struggling to choose between Docker and containerd? Both products offer unique advantages, making it a tough decision.

Docker is a Development solution with tags like containers, virtualization, docker.

It boasts features such as Containerization - Allows packaging application code with dependencies into standardized units, Portability - Containers can run on any OS using Docker engine, Lightweight - Containers share the host OS kernel and do not require a full OS, Isolation - Each container runs in isolation from others on the host, Scalability - Easily scale up or down by adding or removing containers, Versioning - Rollback to previous versions of containers easily, Sharing - Share containers through registries like Docker Hub and pros including Portable deployment across environments, Improved resource utilization, Faster startup times, Microservices architecture support, Simplified dependency management, Consistent development and production environments.

On the other hand, containerd is a Development product tagged with containers, docker, runtime, open-source.

Its standout features include OCI image format support, Container lifecycle management, Image management, Network primitives for creating CNI networks, Integration with Kubernetes via CRI, Task management via runc/io.containerd.runtime.v1.linux, and it shines with pros like Lightweight and fast, Designed for simplicity, Active open source community, Wide platform and OS support.

Product Overview

Docker

Description: Docker is an open platform for developing, shipping, and running applications. It allows developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.

containerd

Description: containerd is an open source container runtime that manages the complete container lifecycle of its host system. It is designed to be lightweight and portable to support container execution on a range of operating systems and platforms.
