The invention provides a Docker-based Web application one-click releasing method. The method comprises the following steps: 1, mirror making: writing a base mirror, a dependent toolkit, a packaged target file and an entrance script program into dockerfile, and generating a specific mirror through a docker build-t appname. command; 2, labeling the mirror and pushing the labeled mirror to a mirror warehouse; and 3, deployment of a container: modifying a Docker arrangement file and executing arrangement. Through adoption of the Docker-based Web application one-click releasing method, a pluralityof compiling processes are prevented from influencing one another, and compiling tools are managed uniformly; the problem concerned with execution of a packaging operation under the same system category is solved; system resources of a single host are multiplexed greatly; and one-click releasing of the whole set of correlated-Web applications is supported, and user care is embodied.
