In addition, for the redundant scheduling process of all containers in the container group, not only will the system resources be wasted due to these container operations, but also the rescheduling process of the container group will increase the risk of scheduling queuing delay, which will seriously affect the online business. Affect service quality and user experience

Embodiment Construction
[0049] The core idea of the present invention to speed up the update of container groups is: through more fine-grained control of container groups, the containers that need to be updated in the container group are "in-place" updated, so as to eliminate repeated operations such as container creation and scheduling, and shorten the time due to container group update The business interruption time brought by this will speed up the business recovery function. "In-place" update refers to running the service container after the service update on the computing node before running the service update. The detailed process of the whole method is as follows: when a container in the container group is updated, first suspend the service of the container group, suspend all other running containers that do not need to be updated through the container suspension persistence technology, and put the container process that does not need to be updated Persist to disk, completely releasing syste...

The invention provides a container group updating method and system with a quick service recovery function. The method comprises the steps of pausing the service of a container group according to an updating request for the container group, determining to-be-updated containers in the container group by comparing the updating request with the current state of the container group, pausing all the containers except the to-be-updated containers in the container group, and persisting the processes of the containers except the to-be-updated containers to a disk; and storing the running state of theto-be-updated container, constructing a new container mirror image according to the container mirror image file needing to be updated in the updating request, destroying the to-be-updated container, running the new container mirror image again according to the running state to obtain an updated container, and restoring the running of the container group to finish the updating of the container group.
Description
technical field [0001] The invention relates to the field of container arrangement in computers, and in particular to a method and system for updating a container group with the function of quick service recovery. Background technique [0002] In the cloud computing scenario, container technology becomes a unified carrier for cluster users to run various applications. A container-based computing business packages the business's executable program and its dependent function library into a job container image. However, when the existing business is run through the container orchestration system, it is usually not possible to run the business itself as a separate business container. Generally, the dependent container that is inseparable from the business needs to run and interact at the same time, that is, the job container and the dependent container must run at the same time to ensure the job. normal operation. For example, the job container often depends on the data volume...
