Is Docker Dead? Best Docker Alternatives 2022

Docker Alternatives

Have you ever come across Docker and found it intriguing? So, do you know what it is? Today, we are here to explain Docker, its features, pros and cons, and most importantly, its features. So, starting off with explaining Docker, it is an open-source platform specifically for developers and system administrators mainly to build, ship, and run distributed applications based on Linux containers. 

Talking about containers, in its totality, Docker is a container engine that makes use of Linux Kernel features, including namespaces and control groups. Docker makes it easier for users to create containers above an operating system and later automate the process of application deployment on the container. 

Docker’s main work is to provide a light environment to run the application code. Moreover, the container makes it possible for users to package up an application and all the necessary parts for operating correctly. Additionally, the applications can be conveniently transferred from one machine to another by incorporating libraries and several other dependencies. 

As mentioned earlier, Dockers uses Linux kernel household that operates on the machine it is working on, and it does not bother any sort of setting or differences. Therefore, the machine is capable of functioning as long as you do not add any non-native element. This feature ensures that the designers get to focus on coding rather than building around a specific system. 

In addition to that, with Dockers, both the developers and system administrators get to take advantage out of it. It makes it easier for designers to lay full emphasis on codes without having to worry about the system. Following are a few of its major components. 


Dockers consist of the following components. 

  • Docker Daemon

The first component of Dockers is the Docket Daemon. This element operates on a host machine and tends to be one of the system’s main elements as we know that the users are unable to interact with Daemon directly. It is only after entering commands into the Docker client. The Daemon finally executes the commands where they are translated first. 

  • Docker Client

Docker Client is the second important component of Docker. This component helps users form a connection with Docker Daemon. It works by processing the commands from the user and later communicating simultaneously with the Daemon to execute those commands. 

  • Docker Images

This component is an only read-only template that provides assistance in launching Docker containers. It can be of CentOS operating system, having the Apache and web application installed. Later on, the system uses the same images to create the Docker containers. Later on, Docker lets users build latest images, or you can easily edit and update the images. 

  • Docker Registries

Docker registries is responsible for Docker images. These registries are public as well as private stores where users choose to upload and download images. So, this registry, which is often being called the Docker Hub, renders a plethora of existing images for usage. All these images can easily be updated and edited, as per the requirement of the users.

  • Docker Container

Docker Container is the last component that acts as an isolated and secure application platform responsible for holding everything required for an application to run. With it, the users can run, start, stop, migrate, and delete operations on a docker container. 


  • Fast and Easy Configuration is one of the main features of Docker. Docker helps in configuring the system aptly and in a far convenient manner. Given to its agility, users can deploy codes in less time and without any exertion. Moreover, it does not require the infrastructure to be associated with the environment, as Docker can be used in the wider range of environments. 
  • The provided containers can be used to run applications in a secluded environment, as these containers are independent and capable of executing all application times.
  • The third important feature is productivity. The productivity is because of the technical configuration and agile deploying applications. Besides providing a secluded environment, it also reduces resources. 
  • Swarm, as the name suggests, clusters tool for Docker containers. The front side uses the Docker API. It is basically a group of self-organizing engines that enables pluggable backends. 
  • Services give an idea about the state of the container within a cluster. Each task in the Services lists provides a container, and it should be running. Swarm, at the same time, schedules them across the nodes. 
  • Security management is one of the most important features. It enables the software to keep all the secrets intact into the swarm. It offers certain access to specific secrets that include certain important commands to the engines, including secret inspect, secret create, and much more. 
  • The bestest feature so far is the ability of containers to work with less computing hardware and get more work done. These containers make it possible for data center operators to learn more workload into less hardware, which implies that there will be less sharing of hardware, ultimately resulting in lower costs. 
  • Containers are portable, self-contained, include secluded disk volume, and offer better software delivery. 
  • The best feature of Docker so far is its best software-defined networking. It is capable of enabling operators with its CLI and Engines just to demonstrate the isolated networks for containers. The developers design the systems with complicated topologies and also in configuration files. 
  • Docker has the capacity to reduce the size, as it offers a smaller footprint of the OS via containers.

Following are few of its advantages

  • The first & the most important benefit of Docker is the Return on Investment, which is commonly referred as the ROI. This advantage is beneficial for big and established companies, having the need to generate revenue over the long term. However, This proves to be beneficial only when it drives down the cost while picking up the profit. 
  • The best part about Docker is how it decreases the deployment in an instant. It is mainly because it has a container for every process and does not require booting at every step. 
  • The ones working on Docker should not worry about the security issues. The application running on containers are totally segregated and separated from each other. This guarantees full control over traffic flow as well as management. 
  • Another benefit of Docker is its simplicity and rapid configuration. It offers great flexibility to users to opt for their own desired configuration, put it into the code, and later deploy it without causing any problem. 
  • The software offers great convenience by letting users build a container image and later allowing them to use the same image at every step. 


Here are a few of its disadvantages. 

  • Docker lacks many important features, including container self-registration, self-inspects, copying files from the host to the container, and similar points like these. 
  • If, by any chance, the container stops working, the users may need a backup and recovery strategy. There are certain solutions available for that, but they lack an automated process yet. 
  • As compared to other virtual machines, the Docker container contains less overhead, but the graph hasn’t been lowered to zero overhead yet. So, if the users run an application directly on a bare-metal server, they get to experience bare-metal speed without using a container or virtual machines. However, on the other hand, containers are unable to run at bare-metal speeds. 
  • One of the major hindrances users faces while using Docker is that if the application is designed to the run in a Docker container on Windows, it won’t run on Linux. If you have a virtual machine, then there is no such limitation. 
  • Docker is not good for applications requiring a rich interface. 
  • It poses challenges, including problems in monitoring different moving pieces within a large-scale and dynamic Docker environment.

Mostly, these functions are executed in groups either in the Linux or zones in the Solaris. Mesos duty is to offer seclusion for the Memory, I/O gadgets, CPU, and the file system. Though the Linux containers are also possible typically, Mesos is peculiar to CPU and Memory. 

7. LXC Linux Container

Docker Alternatives

The last name on the options of best Docker alternativesis LXC Linux Container. The LXC Container consists of three parts: LXC, LXD, the Daemon thread established in GO. These parts are accountable for part managing containers and images. The third component is LXFUSE, and it is responsible for handling the file systems. 

LXC is relatively older and more renowned; however, a lower level set of tools, whereas the LXD element expands on LXC; therefore, it offers a way better management of the container. LXD works by copying the experiences being used for running the readily available Virtual Machines. 

In addition to that, LXD can be configured on Windows and macOS clients both. Though the Linux container has some setbacks, including the absence of Kubernetes integration and LXC failing to become a PCI compliant, still the option proves to be the most convenient substitute for Docker.



All these options serve as the best Docker alternativesbut the choice of selecting one is solely dependent on the user. We advise you to keep in view each option’s features, tools, functions, and features before selecting any alternative.
