Problems solved by technology

[0003] The Docker container only contains the application itself and the libraries that the application depends on, which reflects the simplicity of the container, while the traditional virtual machine encapsulates the entire system inside, which creates a lot of redundancy and additional overhead, so , Docker has the upper hand in many ways compared to traditional virtualization

Embodiment Construction

[0039] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0040] Such as figure 1 A method of image distribution in a docker-based cluster environment is shown, including:

[0041] Use docker to build containers in a cluster environment and package them as images. First, start the container on the development host, and then use the Dockerfile to build the container; package the container as a mirror and perform data persistence. A mirror is a static representation of container content, and a container is a dynamic representation of a static mirror at runtime.

[0042] Identify a docker mirror warehouse in the cluster. In the cluster, it is decided to use a host as the host of the mirror warehouse, and run a container on the host as the Docker mirror warehouse. This allows images to be stored in the mirror repository.

[0043] Share images through docker. If the host in the cluster needs to build a contai...

Abstract

The invention provides a docker-based mirror image distribution method, system and equipment in a cluster environment. The docker-based mirror image distribution method comprises the following steps of: firstly, constructing a container by using a docker in the cluster environment and packaging the container into a mirror image; then, determining a docker mirror image warehouse in the cluster, andcarrying out mirror image sharing through the docker; and finally, enabling the terminal user to perform mirror image distribution through the access agent. According to the method and the system, the mirror images can be copied and distributed to other mirror image warehouses only by being deployed in a single mirror image warehouse, so that large-batch mirror image distribution in a cluster environment is effectively realized.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically relates to a method, system and device for image distribution in a docker-based cluster environment. Background technique [0002] Docker is a lightweight virtualization technology. It is built on top of Linux containers and constructs a brand-new container engine. Its virtualization is implemented on the operating system layer. Its appearance makes application construction easier. Faster, easier to deploy, and easier to share. Application developers can use Docker to package applications and application dependencies into a portable container, and then it can be published on any host that supports Docker. Docker's virtualization is so lightweight. In today's environment, most solutions are virtualized at the operating system level, and the granularity of virtualization is the operating system. The virtualization granularity of Docker is the application program, w...
