A lot of businesses are adopting containers to manage and develop stable applications. Dockers is a widely used and feature-rich tool, and millions of applications are already using it. You can explore the list of Docker Alternatives and determine which one is best for you. Also, Docker is a Linux-based containerisation technology widely used to manage, run and inspect container images for building applications. This article explores substitutes for Docker, encompassing a variety of robust platforms similar to Docker and standalone tools that could function as alternatives to specific components within the Docker ecosystem.

What is Docker?

The Docker is known to be the application containerization platform that is famous in IT circles. This open-source software allows developers to conveniently bundle applications with their dependencies, operating systems, libraries, and other runtime resources into containers, and then deploy them automatically on any infrastructure. Docker is known for deploying, managing, sharing and building containers with the help of simple API commands in the environments.

What are Docker’s features and Benefits?

Docker can be seen offering many benefits for business. We are listing key benefits that are provided by this tool:

Lightweight Container

• Every docker container consists of a single procedure, resulting in a lightweight. It promotes granularly updating the app. The user can modify or edit a single system without downtime for the application.

Enhanced Productivity

• The docker containers are managed, built and deployed compared to the virtual machines. They can complement the DevOps based upon CD/CI pipelines and native architecture to help developers deliver quality software quickly.

Optimize costs

• Running more code on each server empowers you to enhance productivity while keeping costs at a minimum. The best utilization of resources helps in saving a lot of expenses. Also, standard operation promotes automation and saves a lot of human resources and time triggering, saving money.

Smooth Transition Between Infrastructures

• Compared to the Linux containers using machine-specific configurations, the Docker containers are OS-agnostic, machine-agnostic and platform-agnostic.

Big Community Support

• The Dockers enjoy a vibrant community. The users can enjoy many user-uploaded containers via an open-source registry.

Is Docker Still Relevant in 2024?

Docker is used in many container projects, developers and applications today, and all credit goes to its extensive community, modern tools and compatibility. Docker Inc. has undergone many changes recently, and if you are concerned, consider using some of the Docker alternatives.

What Are The Best Docker Alternatives in 2024? 

Here is the list of some of the best Docker Alternatives in 2024:

Buildah

• Buildah is known to be an OCI image-creating tool created by The Red Hat Foundation for containerization systems. Buildah is one of the tools that can offer functionalities similar to running docker build in Docker. Buildah is often used with the Podman. The Podman is also used as the subset for the Buildah functionality for implementing the building procedure.

LXD

• LXD is the container engine that is designed for Linux containers. The LXC allows the user to run all the applications in the virtual environment or isolated containers without giving any technical burden for managing individual kernels. The LXD offers an interface for connecting to the LXC library and making a daemon that is responsible for managing multiple data storage and networking for LXC containers.

Vagrant

• With the Vagrant, the users can replicate many conditionally controlled virtual setups for numerous virtual machines and operating systems. It can help create a virtual environment that duplicates many networks, OSs and VMs. It can facilitate compatibility. The user can build matching virtual environments to deploy, stage and develop apps.

Containers

• It is one of the high-level containers running per the hood for providing an interface between container engines and OS. Runc is known to be a daemon with Linux and Windows support that can abstract OS-specific functionality and will be relatively easier to run and monitor the containers for managing image storage and transfer.

ZeroVM

• It is a secure, portable, lightweight tool known for building an isolated ambience for running single procedures, one at a time. The approach is based on the Chromium Natice client or NaCl project. On the other hand, the other container and virtualization technologies offer a complete virtual OS and a running environment to execute multiple procedures.

Podman

• It is one of the popular container engines. It is also an all-in-one software that can manage, verify, request, and load container images directly via the registry server, allocate, isolate, monitor various system resources and assess containers with the help of bundled containers. It empowers users to manage and utilize containers through a user interface that simplifies the intricacies associated with system security rules and policies such as SELinux and Seccomp.

BuildKit

• Buildkit is one of the second-generation Moby projects that can be used as an experimental feature in many recent Docker versions. Just like traditional Docker, it can run with the help of a daemon. One of the differences between the Buildkit and standard Docker is that the former offers a parallel build process, and the latter builds one layer at a time.

RunC

• It was a module embedded in the Docker architecture and was initially introduced into the industry in 2015. Since then, it has been used widely as an interoperable and standardised container runtime DevOps teams as a part of the custom container engines or as a Docker.

Rkt

• Rkt is known to be one of the application container engines that is best for a cloud production environment. With its native pod framework and adaptable execution environment, rkt seamlessly integrates with various systems, positioning it as a prominent alternative to Docker. Rkt enables you to implement diverse configurations, including isolation parameters, at pod- and application-specific levels.

Microsoft Azure Container Registry

• With the Microsoft Azure Container Registry, the user can access the Docker registry, which allows you to manage and store many container images with the help of Docker command line tools. Also, along with the security features, it provides runtime protection, scanning for vulnerabilities and Twist lock compatibility.

Kaniko

• It is one of the Google building tools that can help create images directly from the Dockerfiles. Kaniko does not work with the daemon like Buildah and stresses more on creating images with the help of Kubernetes. The Kaniko is inconvenient for local development as it runs in the image along with the Kubernetes.

Serverless Architecture

• It is a famous architecture used widely as an alternative for Docker containerization. As per their name, the serverless architecture is used to get rid of the requirement of server management or underlying infrastructure to work for the application. It does not entail that servers are not required, but the cloud vendors manage the jobs well. The developers can write the code, delay and package on the platforms.

VMs from VMware

• Deploying virtual machines from VMware is another viable choice for Docker. Also, VMware is at the top position in the virtualization industry. Docker abstracts resources at the OS level, whereas VMware virtualizes the hardware layer. The vSpher is one of the key offerings of the VM ware containing different tools for assisting clod virtualization OS.

Cloud Foundry

• Cloud Foundry, overseen by the Cloud Foundry Foundation, is an open-source Platform-as-a-Service (PaaS) solution. VMware engineers initially developed it in 2011 using Ruby, Java and GO. Cloud Foundry has gained recognition for its robust support for continuous delivery, enabling efficient product lifecycle management. Its container-centric architecture is particularly renowned in multi-cloud environments, as it simplifies container deployment across various platforms and facilitates smooth workload migration without disrupting applications.

Apache Mesos

• It is a data centre management software and open-source container developed by Apache Software Foundation. Apache Mesos was initially created by Nexus and was coded in C++. It is an abstraction tool for isolating virtual resources from the physical hardware. The user can run apps like Spark, Hadoop, Kubernetes, etc.

Conclusion
