Containerization Docker has many advantages, but it depends case to case. I extensively used Containerization Docker for gaming platform, and found some of major disadvantages during deployment and after that.
While Docker has earned its place as a game-changer in the realm of software deployment, it is not entirely devoid of challenges. Even though 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. Let's explore the disadvantages I experienced while using Containerization Docker for a gaming platform:
1) Certain container products do not get along well with others, primarily due to competition among supporting companies. Consider OpenShift, Red Hat’s container-as-a-service platform. It only works with the Kubernetes orchestrator, limiting its compatibility with other software.
2) Shutting down a docker container may result in the loss of all of its data unless we store it somewhere else first. Solutions such as Docker Data Volumes exist to preserve data persistently, but implementing them could be challenging.
3) Docker was initially designed to run server applications without a graphical user interface. Thus, running GUI software within a container using clever tactics might not always provide a reliable solution.
4) A noteworthy disadvantage of Docker is its necessity for programs designed as a collection of discrete microservices. The sole significant advantage of Docker lies in its ability to ease application distribution, which may not be useful for all types of applications.
5) While better storage options are on the horizon, currently, there isn't a truly seamless solution for connecting containers to storage. Docker Data Volumes require intense host deployment and manual configuration.
6) The single monitoring solution Docker providers can be limiting. If you require just basic information on the containers, Docker's stats command suffices. Although external solutions like Advisor offer additional monitoring, this highlights Docker's own monitoring insufficiencies.
7) When a Docker container crashes, we need a backup and recovery plan. Solutions do exist, but they are not automated or highly scalable, raising questions about Docker's reliability.
8) Another major shortcoming is its operating system limitation. If an app is programmed to work in a Docker container on Windows, it won't function on a Linux system, and vice versa, unlike virtual machines.
9) Docker sees continuous progress, which although good, can create issues if its documentation does not keep up the pace. This can leave users searching for specific information, particularly when using Mac or Windows systems.
While Docker can revolutionize application distribution, it comes with its own set of drawbacks. Understanding Docker's disadvantages is crucial for efficient management and effective utilization.
