Let us take a closer look at the disadvantages of containerization docker and its effects on docker management. At Bobcares our Docker hosting support services will give you a detailed note on the disadvantages of Docker.

Docker’s Disadvantages

The following given are some of the major disadvantages of containerization docker:              

Containers don’t run at bare-metal speeds:

Containers require fewer resources than virtual machines. However, containers still incur performance costs as a result of overlay networking, interface between containers and the host system, and so on. If we want to get 100 percent bare-metal performance, we must employ bare metal rather than containers.        

The container ecosystem:

Although the Docker platform as a whole is open source, certain container products do not operate with others, mainly owing to rivalry among the firms that support them. OpenShift, Red Hat’s container-as-a-service platform, for example, only works with the Kubernetes orchestrator.

Persistent data storage:

This is one of the major disadvantages of containerization docker. Shutting down the container will result in the loss of all of its data unless we store it somewhere else first. There are solutions to preserve data persistently in Docker, such as Docker Data Volumes, but this is difficult.         

Graphical applications don’t work well:

Docker was created to provide a method for delivering server applications that do not require a graphical user interface. While there are various clever techniques for running a GUI software within a container, these solutions are not dependable to cure the disadvantages of containerization docker.

Not all applications benefit from containers:

Another disadvantage of containerization docker is that the containers will benefit only from programs that are designed to function as a collection of discrete microservices. The sole true advantage of Docker is that it may ease application distribution by offering a straightforward packaging method.

Docker storage is still hard:

Better Docker container storage choices are on the way. However, there is currently no truly seamless way to connect containers to storage and that is a major disadvantage of containerization docker. Docker Data Volumes need extensive deployment on the host as well as manual configuration. They tackle the storage problem, but not in a very user-friendly or efficient manner.

Docker has poor monitoring:

The stats command is the sole form of monitoring solution provided by Docker. That is sufficient if we only require basic information on the containers. CAdvisor, for example, is a third-party solution that provides additional monitoring. Note that the poor monitoring of coker is one of the major disadvantages of containerization docker.

Missing Docker container features

A slew of feature requests is in the works, including container self-registration and self-inspections, file transfer from the host to the container, and many more.

Data in the container

When a Docker container fails, it requires a backup and recovery plan; however, while we have numerous solutions for this, they are not currently automated or extremely scalable. This makes containerization docker unreliable and is one of the major disadvantages.

Run applications as fast as a bare-metal serve

Docker containers have less overhead than virtual computers, but not zero overhead. We can achieve genuine bare-metal performance when we execute an application directly on a bare-metal server, even without using containers or virtual machines. The Disadvantage of containerization docker at this process is that it does not operate at bare-metal rates.       

Provide cross-platform compatibility

The main issue is that if a program is built to operate in a Docker container on Windows, it will not work on Linux and vice versa. This constraint does not apply to virtual computers. As a result of this constraint, Docker is less suitable in some extremely diverse setups that include both Windows and Linux systems.

Run applications with graphical interfaces

Docker, in general, is intended for hosting command-line programs. Though there are a few methods for running a graphical interface within a Docker container, they are cumbersome. considering this disadvantage of the containerization docker, we have to conclude that Docker is not a good choice for applications that demand extensive interfaces. 

Solve all the security problems

Before shifting workloads to Docker, we must identify and mitigate Docker-specific security concerns. It is due to the extra security risks introduced by Docker, such as the challenges in monitoring numerous moving pieces in a large-scale, dynamic Docker system.

Advances Quickly

Docker is constantly evolving, making app development and deployment easier and more efficient. This can be a concern since the supporting documentation does not always change as rapidly as the technology. When utilizing Mac or Windows, this might leave developers searching for information on specifics, particularly inside the abstract levels.

Learning Curve

Switching to Docker containers might be a steep learning curve for certain engineers. Even individuals with experience in virtualization architecture find some Docker principles difficult to grasp. Working with a user-friendly container-based tool can help the developers get the most out of the Docker environment.
