What is Docker?

Docker is the most widely used software for managing and containerizing data. Numerous businesses, including large corporations, start-ups, and platforms designed exclusively for mobile devices, have used it. Its popularity results from the variety of features and ease of use. Developers are tempted to rely on it for their containerization needs because it is quick and straightforward.

However, just as not all businesses use containers in the same manner, not all companies are also created the same. Docker might not be the best option because different applications have different needs and reasons for containerization software.

Here is a list of 10 alternative containers you can use besides Docker:

1. ZeroVM:

Neocons are against it, but I genuinely support it. It is based on Google’s Chromium Native Client and is open-source and lightweight. The term “VM” stands for “Virtual Machine,” albeit it differs from standard VMs in that it merely virtualizes the space required to run the program, enabling quicker deployment and isolation. Unauthenticated code can execute without fear of attack or interception because it is rapid and safe.

2. Podman:

For Linux systems, Podman outperforms Docker in several areas. Instead of accessing the system through privileges as Docker does, it integrates directly with plans to execute containers in the background without root privileges. It adds additional security to have this capability that can only be accessed through the local system. Another benefit of Podman is that it provides a more extensive and accommodating toolkit for integrating files designed for Docker.

3. Vagrant:

Vagrant’s primary use is to operate numerous virtual machines with various operating systems simultaneously on a single computer. These virtual computers can be saved as pictures and distributed across team members concurrently working on the same project. While Vagrant offers users additional customization and accessibility options, this docking solution only permits isolation at the user level.

4. OpenVZ:

OpenVZ is comparable to Docker in terms of functionalities, although it comes with a distinct set of utilities. With OpenVZ, users can build many separate, segregated Linux containers on a single server. Each container has a unique virtual server with different IP addresses, system libraries, applications, and files developed from the ground up.

For the development of applications across devices that are linked to the same network, OpenVZ offers independent access and activation. You receive a unique Network File System with OpenVZ that enables users to administer its virtual servers freely. System administrators often manage them, but any user with the right training can do it. Although hosting virtual servers is its primary goal, it may also be used to create programs for those servers, much like Docker.

5. Rancher:

For large-scale projects involving numerous teams, container clusters are frequently necessary. Docker has a subsidiary called Docker Swarm to handle them. Rancher is a piece of software that enables the deployment of substantial development networks across various businesses. Based on the choices and configurations of the administrator, it automates cluster management. Permissions and rights can be automatically assigned when all the clusters have been set up according to departments, ensuring that everyone has easy access to their appropriate environment.

6. Buildah:

Comparatively speaking to Docker, Buildah offers much more control over images. Buildah allows you to commit numerous changes to one layer at a time, whereas they both use some of the same functions. Additionally, it may produce blank images, allowing the isolated environment to be designed from scratch using only the essential tools. Each user’s perspective on photos increases security inside teams but makes it harder to share work.

7. Containers:

A standalone container runtime program called Containers was formerly a component of Docker’s toolbox. It can run without Docker and be installed alongside or separately from it. Containers are an alternative to other runtimes for lower-level development because they concentrate solely on being low-level containers. It may then be easily updated and accessed through Docker, complementing other runtimes and a logical next step in the Docker adoption process.

8. VirtualBox:

When compared to VirtualBox, Docker is lacking in functionalities, for example. Users of VirtualBox, for instance, can run multiple virtual machines that run on various operating systems, a feature that Docker lacks. Furthermore, since the virtual machine doesn’t use the same host computer, data can be transferred easily from one OS to another through cloud-based storage (without jeopardizing the user’s security). Even though it isn’t as lightweight as other virtual operating systems, disregarding the ability to transfer files and apps between them would prevent entire industries from progressing.

9. run:

Originally a component of Docker, the program runs split out to improve container mobility. Development and testing may be done more effectively in isolated settings thanks to its containers, which can be utilized with any operating system and operate swiftly. Its mobility also ensures that upgrades will proceed smoothly. It also functions with or without Docker. Runs can keep things rolling if disruptions happen in areas with restricted access until everything is back up and running.

10. LXC (Linux Containers):

A component of Linux called LXC (Linux Containers) enables users to run various isolated environments on a single computer. LXC has been improved to compete with Docker in areas like disk performance and volume management while also having the ability to share IP addresses and system files on the host machine. LXC does this by using the host machine’s Linux natively. LXC uses fewer resources than its rivals while offering all the features required for hypersupervising artificial settings.

How to get started with containerization

They often meet with DevOps personnel as part of their job to go over their container strategy. Most of the time, the people I speak with are anxious to take advantage of the many advantages containers offer, but they haven’t used them before. They might have one or two container-based systems on-site or in the cloud, but they lack a defined approach.

Containers are incredibly disruptive, so it’s simple to become giddy and want to go all in. But I advise them to be very explicit about their short- and long-term goals and to include the runway they’ll need to become accustomed to containers and the culture around them.

The main reasons DevOps teams want to start using containers are:

-Speed up application development and deployment: 

Utilizing pre-existing images as templates makes it simple to create containers, which speeds up production. Additionally, just as easy as if it were still in the development phase, you can package your work as a container image and distribute it to run in any environment. Making use of automation solutions like CI/CD only accelerates the procedure.

-Move applications to the cloud: 

Because you can move containers simply from one host to another, they are helpful. Your apps can be easily deployed on-premises or in the cloud because you don’t need to update any code (private or public).

-Transition to microservices:

Containers are made to meet microservice designs by being single-purpose, single-process devices. Organizations aspire to develop and maintain their apps more effectively than before, moving away from large, hard-to-manage monolithic systems. The ecosystem that has grown up around containers makes it possible for even the most prominent enterprises to expand their microservices ambitions. Containers are suitable for the development of microservices.

The numerous benefits of containerizing your apps, but where should you start? Should you convert your old monolithic program to containers for microservices or simply the “new stuff”?


Although Docker is a fantastic option, it is not the only one available. This blog post is for you if you’re seeking a Docker substitute or are just starting to research containerization alternatives. We have prepared ten distinct containerization solutions that are worth taking into consideration.
