Docker containers will help you to isolate and pack your software with all its dependencies. And Kubernetes will help you to deploy and orchestrate your containers. This lets you focus on developing new features and fixing bugs more rapidly.For starters, Docker Compose is designed to run on a single host or cluster, while Kubernetes is more agile in incorporating multiple cloud environments and clusters. Kubernetes is easier to scale beyond a certain point plus you can utilize native services of AWS , Azure and GCP to support our deployment.Why Do We Use Kubernetes One of the benefits of Kubernetes is that it makes building and running complex applications much simpler. Here's a handful of the many Kubernetes features: Standard services like local DNS and basic load-balancing that most applications need, and are easy to use.

How Kubernetes and Docker work together : Now, we have made it amply clear that Docker helps you in creating the containers while Kubernetes facilitates their management at run time. While Docker packages and ships the application, Kubernetes helps you to deploy and scale the application. So, it can be inferred that both go together.

Can Docker run without Kubernetes

Can You Use Docker Without Kubernetes The short and simple answer is yes, Docker can function without Kubernetes. You see, Docker is a standalone software designed to run containerized applications. Since container creation is part of Docker, you don't need any separate software for Docker to execute.

Does Kubernetes still use Docker : Kubernetes is removing support for Docker as a container runtime. Kubernetes does not actually handle the process of running containers on a machine. Instead, it relies on another piece of software called a container runtime.

The following are some of the top benefits of using Kubernetes to manage your microservices architecture.

1. Container orchestration savings.
2. Increased DevOps efficiency for microservices architecture.
3. Deploying workloads in multicloud environments.
4. More portability with less chance of vendor lock-in.

When should you not use Kubernetes

Moreover, if your application stack is simple, not distributed, or doesn't require advanced features like auto-scaling, self-healing, and service discovery, Kubernetes might be an overkill. Its complexity and overhead may lead to more problems than solutions.Although the Kubernetes project has deprecated dockershim, Docker containers still work with Kubernetes, and images produced with the docker build command still work with all CRI implementations.Even though using Docker with Kubernetes is a common practice, it does not mean that Kubernetes cannot function without Docker. Though it does need a container runtime, it doesn't always need to be Docker. You can use any other container runtime with Kubernetes to get the job done.

When it is used as a container runtime for Kubernetes, Docker is just a middle-man between Kubernetes and containerd. However, Kubernetes can use containerd directly as a container runtime, meaning Docker is no longer needed in this middle-man role. Docker still has a lot to offer, even in a Kubernetes ecosystem.

Why you don’t need Kubernetes : Wrong. While Kubernetes itself is open source, the process of adopting Kubernetes for your organisation will be expensive. Here's what that looks like: All of the redundancy and resiliency offered by Kubernetes itself is accomplished by creating a large and rather expensive infrastructure as a starting point.

Why is Docker being deprecated in Kubernetes : With the release of Kubernetes v1. 20 in 2021(!), Docker was officially dropped as a supported CRI implementation. Instead, Kubernetes encourages the use of CRI-compliant runtimes such as Containerd and CRI-O, which better align with the CRI requirements and offer enhanced features.

Is Kubernetes still using Docker

Although the Kubernetes project has deprecated dockershim, Docker containers still work with Kubernetes, and images produced with the docker build command still work with all CRI implementations. However, the removal of dockershim raises some potential issues for Docker users.

Docker has been the big name when it comes to building and running containers, and Kubernetes has been the big name when it comes to managing and orchestrating them. It might seem a bit shocking to hear that Kubernetes is deprecating support for Docker as a container runtime starting with Kubernetes version 1.20.Docker containers are one process per container. Kubernetes is particularly useful for DevOps teams since it offers service discovery, load balancing within the cluster, automated rollouts and rollbacks, self-healing of containers that fail, and configuration management.

What is the biggest disadvantage of Kubernetes : Disadvantages: Despite its numerous advantages, Kubernetes also poses some challenges: 1. Complexity: Kubernetes has a steep learning curve and requires expertise in containerization, networking, and distributed systems, making it challenging for inexperienced users to deploy and manage effectively.
