Problems solved by technology
The startup time of the container mainly depends on the download time of the image and the time of business startup (or business initialization). In related technologies, the entire business image is pulled from the mirror warehouse and written to the disk of the local computer. The container is also large, so the download time of the business image is long, and the large-scale application requires a long time to start the business, which seriously affects the startup speed of the container, and cannot meet the requirements of container startup in serverless architecture or edge scenarios.

The invention discloses a container starting method and device, and the method comprises the steps that a first server receives a container starting request, and the container starting request comprises a mirror image name of a service mirror image; the first server obtains auxiliary mirror images according to the mirror image names, wherein the auxiliary mirror images are in one-to-one correspondence with the service mirror images; the first server lazy loads part of information of the service mirror image based on the auxiliary mirror image so as to establish a process and a running environment of the process, and the part of information comprises necessary files needed when the container is started; the first server guides the process to run in the running environment based on the auxiliary mirror image so as to start the container. By implementing the embodiment of the invention, the initialization time of the process when the container is started can be saved, and the starting speed of the container is increased.
Description
technical field [0001] The application field of computer application technology, in particular, relates to a method and device for starting a container. Background technique [0002] In a computer system, a container is a virtualization of resources at the operating system level to isolate processes and resources. Due to the technical characteristics of container technology such as lightweight, high performance, resource saving, and cross-platform, the application range of containers is becoming wider and wider. A container has its own file system, CPU, and memory, which means that it can run independently like a virtual machine with fewer resources. [0003] Containers are generated based on images, and containers are running instances of images. The startup time of the container mainly depends on the download time of the image and the time of business startup (or business initialization). In related technologies, the entire business image is pulled from the mirror wareho...
