An embodiment of the invention provides a management method for application processes in a Docker container. The method comprises the following steps: an initialization process is set; bifurcation operation is performed on the initialization process, and an initial process and a first child process are obtained; system signal registration operation is performed in the initial process, and the first child process and at least one application process are taken over by monitoring system signals, forwarding the system signals to the first child process and calling at least one application process loaded into the Docker container by the first child process executes system, wherein the at least one application process is loaded into the Docker container when the first child process executes system call. The initial process and child processes are obtained by performing bifurcation operation on the initialization process, the initial process controls the child processes and application processes by means of system signal registration and forwarding, and with adoption of the method, the application processes can be terminated timely and resources of orphan processes can be released timely. Besides, the embodiment of the invention provides a management device for the application processes in the Docker container and a computer readable storage medium.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of the Internet, and more specifically, the embodiments of the present invention relate to a method, a device, and a computer-readable storage medium for managing an application process in a Docker container. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Docker container is an open source application container engine, developers can package their applications and dependencies into a portable container, and then publish to any popular Linux machine, and virtualization can also be realized. The containers that developers have passed the test in their development environment can be deployed in batches in different versions of Linux production environments, and the containers can ...
