What is Docker not good for?
The question is about Docker
Docker is not ideal for applications requiring persistent data storage, complex multi-container setups without orchestration tools, or high-performance computing tasks. It struggles when Docker needs to work with low-level access to hardware or when graphical user interface-based applications are in the running. Small, lightweight applications are not targeted appropriately by Docker since the application requires containerization overhead. Most often, it is orchestration tools like Kubernetes that are added to perform Enterprise scaling, further adding to the complexity. Complete isolation, as provided by virtual machines, is lacking in Docker containers, making them less secure for certain use cases. Powerful though Docker is, its limitations make it unsuitable for certain niche or highly specialized environments.
