What is a docker container?

Developers who have come into contact with the concept of containers must have heard of docker, docker is a world-renowned open source application container engine, and its influence in the industry is very large.

Docker containers allow developers to package their applications and dependencies into a portable image that can then be distributed to any popular Linux or Windows machine, or virtualized.

Docker is a lightweight container management engine that emerged as a bridge between software development and cloud computing platforms. If we label containers as virtual machines, Docker can be labeled as hypervisor management layer, which is a container management engine technology, not the container itself.

Docker provides an elegant and concise set of tools that leverage the existing technologies of the Linux open source ecosystem to achieve complete, simple, efficient, and fast management of the horizontal and vertical life cycles of containers.

Docker provides various Kubernetes Engine management tools (such as distribution, version, migration, etc.) so that users can manage and use containers more simply and clearly without paying attention to the underlying operations;

Docker reduces migration difficulty and greatly improves user experience by introducing hierarchical file system construction and efficient mirroring mechanism. Users can manipulate Docker containers as easily as the application itself.

Docker's idea is to realize "Build, Ship and Run Any App, Anywhere" that is, to manage the application's packaging, distribution, deployment and Runtime life cycle, so as to achieve the goal of "packaging once and running everywhere" of application components.

The application component here can be a Web application, a compilation environment, a set of database platform services, or even an operating system or cluster.

Based on multiple open source technologies on Linux, Docker provides an efficient, agile and lightweight container solution that supports deployment to on-premises environments and multiple mainstream cloud platforms. Docker provides, for the first time, a one-stop practical solution for app development, operation and deployment.

About docker container is what to share here, hope the above content can have some help to everyone, can learn more knowledge. If you think the article is good, you can share it so that more people can see it.
