Abstract

The invention discloses a method, apparatus and system for realizing elastic expansion of an application example based on a container. The method comprises the following steps: determining a target host node and a target container corresponding to a target application; determining an index of an elastic expansion strategy corresponding to the target application; obtaining an actual value of the index corresponding to the target container; and if it is judged that the number of the containers of the target application needs to be adjusted according to the actual value of the index and the elastic expansion strategy, sending a container number adjustment instruction to a Docker Swarm component, so that the Docker Swarm component adjusts the number of the containers. Therefore, in the embodiment, the obtained actual value of the index is matched with the predetermined elastic expansion strategy to automatically trigger the Swarm cluster component to perform scheduling to create or delete the containers, automatic capacity expansion or expansion of the application example under a certain condition, thereby improving the high reliability of the application based on the container.

Description

technical field [0001] The present invention relates to the technical field of elastic scaling of application instances, and more specifically, to a container-based implementation method, device and system for elastic scaling of application instances. Background technique [0002] The Docker Swarm cluster component is the cluster management component of the Docker container. Docker Swarm can manage multiple Docker Deamon. Containers provide applications with isolated running spaces. Each container contains an exclusive and complete user environment space, and changes in one container will not affect the running environment of other containers. At present, the Docker Swarm cluster component can implement cluster management on hosts, but after the Docker Swarm cluster component initially creates a predetermined number of application instances, the number of application instances is fixed. However, when the load of the application is too large or too small, Swarm cannot automa...
