Docker container building method and Docker management console

Abstract

The invention discloses a Docker container building method and a Docker management console. By adding a layer combining instruction into an image building script, combining of multiple image layers can be realized according to the layer combining instruction in the process of Docker image building, so that number of Docker image levels and data size of an image file are reduced, working efficiency is improved, and storage resources are saved. The method includes: acquiring a related application file and an image building script of an application, wherein the image building script contains a layer combining instruction; performing image compiling on the related application file according to the image building script to acquire a Docker image layer; if a current instruction is the layer combining instruction, acquiring an image file of a current image layer in the Docker image layer, and acquiring an image file of a target image layer corresponding to a target image layer identity; acquiring a difference file according to the image file of the current image layer and the image file of the target image layer, and building a layer-combined image layer according to the difference file; submitting the layer-combined image layer to an image repository.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a Docker container construction method and a Docker management console. Background technique [0002] In computers, virtualization (Virtualization) is a resource management technology that abstracts and transforms various physical resources of computers, such as servers, networks, memory, and storage, to break the inseparability of physical structures. barriers, so that users can use these resources in a better way than the original configuration. The new virtual portion of these resources is independent of how existing resources are set up, geographically or physically configured. Generally referred to virtual resources include computing power and storage capacity. In the actual production environment, virtualization technology is mainly used to solve the overcapacity of high-performance physical hardware and the reorganization and reuse of old hardware with low capacity, an...

Problems solved by technology

[0010] 1. The Docker image level limit cannot exceed 127 layers. Therefore, the number of image layers for compiling a new image version is limited. If more than 127 layers need to be merged, due to the large number of image layers, the operations performed by each layer are complicated. There are many files that cause changes. When merging mirror layers, it will be extremely time-consuming and inefficient to compare each layer with the previous layer files;

[0011] 2. When updating the Docker image, it is necessary to compare the level information of the image each time, and whether each image layer in the image warehouse exists on the container host. The more image levels, the more time-consuming the corresponding comparison;

[0012] 3. Each mirror layer needs to occupy a certain amount of disk space, and the mirror layer is inherited in a tree structure, so not every file in the mirror layer is necessary, resulting in the storage resources of the mirror warehouse server and container host waste;

[0013] The above three shortcomings lead to low work efficiency of the Docker container platform system deployed in clusters and waste of storage resources
