Technology and Docker

On January 20, YJ, a pre-sales expert of Shenxin Cloud, shared "Introduction to Container Technology and Docker" in the series of live classes of "Cloud Gathering Technology Society" of Xinxin Cloud, and introduced in detail the development of container technology, container technology ecology represented by Docker, and application scenarios of container technology. The following is a summary of the content he shared. If you want to know more, you can follow the official account of "Shenxin Technology" to watch the live replay.

The development of container technology began in the 1970s. Under the background of rapid development of computing power, scientists focused on how to improve resource utilization. As a result, the earliest resource isolation technology, such as chroot, emerged. Resource isolation technology has continued to develop to the early 21st century. Namespace, Cgroup and other resource isolation technologies have joined the Linux kernel, forming a kernel standard LXC container technology.

Advantages and characteristics of container technology

• Agile environment
• Improve productivity
• Versioning
• Standardization
• Security

Based on these backgrounds, an engineer named Solomon Hykes proposed a solution for modern containers. He integrated these technologies into an out of the box software and added many functions such as user-friendly management interface, large-scale management, storage format, etc. These capabilities have now become the standard capabilities of containers.

First, Docker is the pioneer of container technology. Based on LXC, Docker reduces the complexity of using container technology and proposes a management, operation and maintenance scheme for large-scale use. It pioneered that the image file realized the "encapsulation and running everywhere" of the application and running environment, and further promoted the popularity of the technology.

Second, Docker is the promoter of container technology. The DockerHub image warehouse has built a developer community and ecology based on image, allowing developers all over the world to participate in ecological construction and sharing, making great contributions to the popularization of container technology. Docker has also gained rapid development and leadership.

Third, Docker is the standard driver. Docker has contributed to and led the development of container image and runtime OCI standards, accelerating the development of container technology. At the same time, he also contributed containerd, participated in the development of CRI standards, promoted the development of container ecology and organization, and finally achieved industrial application.
