What are the characteristics of docker?

Docker’s design philosophy is: container, standardization and isolation. The design features of Docker include the following:

Lightweight

Multiple Docker containers running on a machine can share the operating system kernel of the machine; it can be started quickly, and It only requires very few computing and memory resources. The image is constructed through the file system layer and shares some common files, so that disk usage can be minimized and the image can be downloaded faster;

Standard

Docker containers are based on open Standard, capable of running on all mainstream Linux versions, Microsoft Windows, and any infrastructure including VMs, bare metal servers, and clouds;

Security

Docker gives applications isolation, not just Limited to being isolated from each other and independent of the underlying infrastructure. Docker provides the strongest isolation by default, so if there is an application problem, it is only a problem with a single container and will not affect the entire machine.
