Problems solved by technology

Therefore, in the production environment, the cold start of the container often takes several minutes, and as the scale expands, the image warehouse will not be able to download the image quickly due to network congestion in the cluster.
[0004] In order to speed up container startup, there are three traditional solutions: image caching, preloading, and image size reduction. However, preloading can only alleviate the delay of some images, and reducing the image size cannot avoid the need to use large In the case of volumetric mirroring
The current traditional method has the problem of long time-consuming cold start

Abstract

The invention relates to a container starting method and device, computer equipment and a storage medium. The container starting method comprises the following steps: in response to binding of a container to a working node, monitoring whether a mirror image corresponding to the container exists on the working node or not; if it is monitored that no mirror image exists on the working node, a daemon process is started, and a mirror image pulling task is issued to a container running assembly through the daemon process; wherein the mirror image pulling task is used for indicating the container running component to pull a mirror image from a far-end mirror image warehouse to a working node; and in response to issuing of the mirror image pulling task, creating a target directory on the working node, and mounting the mirror images in the remote mirror image warehouse to the target directory to indicate the container to read the mirror images from the remote mirror image warehouse based on the target directory so as to complete container starting. The problem of long consumed time of cold start can be solved.

Description

technical field [0001] The present application relates to the field of cloud computing technologies, and in particular, to a container startup method, apparatus, computer equipment and storage medium. Background technique [0002] With the explosion of Kubernetes and cloud-native technologies, the large-scale application of containers in enterprises has become more and more extensive. Fast deployment and startup is one of the core advantages of containers. Fast startup here means that the instantiation time of the local image is very short, that is, the "hot startup" time is short. However, for "cold start", that is, in the case of no local image, you need to download the image from the image repository before creating the container. [0003] At present, after long-term maintenance and update of business images, both the number of image layers and the overall size will reach a large order of magnitude, such as hundreds of MB or several GB. Therefore, in the production envi...
