Resource isolation: Docker provides strong resource isolation through namespaces and control groups, avoiding interference between different applications and improving system stability and security.
Lightweight: Another key feature of Docker is its lightweight design. Each Docker container is an independent runtime environment that contains the application and all of its dependencies, but does not require the allocation of resources to the entire operating system like traditional virtual machines. This allows docker to be started and stopped quickly on the host and consumes very little system resources, making it ideal for use in resource-constrained environments.
Rapid deployment: Docker enables rapid deployment by packaging applications into images. Developers can easily create, distribute, and run images, greatly shortening the deployment cycle from development to production. This helps the team iterate quickly and respond to market changes.
Continuous Integration Continuous Deployment (CI CD) support: Docker is tightly integrated with the DevOps toolchain to make the build, test, and deployment process smoother. With automated tools, the entire process from submission to new container generation can be automated, further improving the speed and quality of software delivery.
Easy backup and recovery: Because docker containers are self-contained, backup and recovery is as simple as backing up the corresponding images and data volumes, without worrying about the complexity of the underlying infrastructure.
Open source community support: As an open source project, Docker has a huge community support, and new plugins, tools, and services are constantly emerging, enriching the functions of Docker, and providing rich learning resources and solutions.
Rich ecosystem: The Docker ecosystem includes many app stores, Docker Hub, and users can directly use pre-built images to meet various needs, which greatly reduces the entry threshold and operation and maintenance costs for developers. At the same time, tools such as Docker Compose make it easy to manage and orchestrate multi-container services.
