Empowering Scalability and Seamless Deployment in Software Development with Containerd


Containerization has transformed software development, which makes scalability and effective application deployment possible. Container runtimes became crucial for controlling container lifecycles as containers became popular. Containerd is one such runtime that has gained popularity. This blog will examine Containerd, its features, and its effects on the ecosystem.


Docker first created an open-source container runtime called Containerd as a component of their container platform. Later, though, it became a stand-alone project and was given to the Cloud Native Computing Foundation (CNCF). It is now crucial to many orchestrators, cloud infrastructures, and container systems.

Key features Containerd

  • Compatibility – The Open Container Initiative (OCI) specification is compatible with Containerd, allowing it to operate without a hitch with containers created using OCI’s common runtimes and images.
  • Stability and Reliability – Containerd is designed to be strong, stable, and extremely reliable, emphasizing predictability and performance as it drives crucial container activities in production environments.
  • Remote API – Users can control container lifecycles, pictures, and other relevant capabilities remotely thanks to Containerd’s robust remote API. Container management tools and orchestration frameworks like Kubernetes can use this API.
  • Snapshotter and Image Distribution – Containerd uses snapshotter technology to produce compact and effective container images. It also enables pulling images from container registries like Docker Hub, among other image distribution techniques.
  • Plugin Architecture – Containerd’s plugin-based architecture makes it simple for developers to add new features. Due to its extensibility, containerd has developed a thriving ecosystem of plugins that serve various purposes.

Steps to install and use Containerd

Step 1 – Create a VM on GCP using Ubuntu

Step 2 – Install Docker




Install jdk


Step 3 – Create a Java file

Create a Docker file











Containerd has emerged as a fundamental building block in the container ecosystem, powering millions of containers in production environments worldwide. Its status as a top container runtime has been cemented by its simple architecture, adherence to OCI standards, and tight integration with Kubernetes.

Containerd’s influence is anticipated to increase as containerization continues to influence contemporary software development and infrastructure, offering a smooth container experience for developers and operators alike.

1. What is Containerd?

ANS: – An open-source container runtime called Containerd is created to control the lifespan of containers on a host system. It acts as the main container runtime for several container platforms, including Docker and Kubernetes. Developers can run and maintain containerized applications more easily and securely thanks to Containerd’s fundamental functionality for container execution, image management, and storage.

2. How does containerd differ from Docker?

ANS: – Although Docker was a major factor in the rise of containers, containerd is a more specialized and narrowly focused component. At first, Docker was a complete solution that included networking, image creation, container runtime, and other features. Containerd, on the other hand, acts as a compact, isolated runtime intended for usage in production. Utilizing containerd’s efficiency and security advantages, Docker now uses containerd as its default runtime to execute containers.

3. How is containerd related to Kubernetes?

ANS: – As one of the container runtimes supported by the Kubernetes Container Runtime Interface (CRI), Containerd plays a significant part in Kubernetes. Using the CRI interface, Kubernetes may manage the execution of containers by interacting with various container runtimes. Container management and integration within Kubernetes clusters are made possible via communication between Kubernetes and containerd over the CRI as necessary. Because of its dependability and efficiency, Containerd is frequently chosen as the CRI implementation for many Kubernetes deployments.
