Problems solved by technology

like figure 2 As shown, in this independent mirror warehouse system, a set of mirror warehouses is set up for each cluster. In this solution, mirror images need to be uploaded separately for each cluster, and deployment scripts must be modified for each cluster to point all mirror addresses to this The existence of multiple sets of container images and copies of deployment scripts in the cluster's mirror warehouse not only increases the complexity of cross-cluster deployment of applications, but also makes it difficult to maintain

Abstract

The present invention discloses a system and a method for multi-cluster container deployment. The system comprises: a container engine configured to send a mirror image download address obtaining request to a local mirror image warehouse, wherein the request comprises a mirror image identifier, and a container mirror image is downloaded from the local mirror image warehouse through a mirror imagedownload URL; the local mirror image warehouse configured to inquire whether the container mirror image corresponding to the mirror image identifier has been stored or cached or not, wherein, if yes,the mirror image download URL is directly returned to the container engine, or else, the mirror image download URL pointing to a remote mirror image warehouse is inquired from the mirror image management center, a missing container mirror image is downloaded into the local mirror image cache from the remote mirror image warehouse to generate a mirror image download URL pointing to the local mirrorimage cache, and the mirror image download URL is reported to the mirror image management center and is returned back the container engine; and the mirror image management center configured to returnback the mirror image download URL pointing to the remote mirror image warehouse to the local mirror image warehouse. The system and the method for multi-cluster container deployment can improve thecontainer application cross-cluster deployment efficiency.

Description

technical field [0001] The present invention relates to the field of cloud computing, in particular to a system and method for multi-cluster container deployment. Background technique [0002] Container applications are usually deployed in the form of container images + deployment scripts. First, the container images are uploaded to the mirror warehouse, and then the deployment scripts are executed by the container cluster orchestrator, and the container engine is scheduled to download the container images and run container instances. Large-scale container applications often need to be deployed in multiple container clusters in many business scenarios, such as business migration, partitioned services, and disaster recovery backup. Existing methods for cross-cluster deployment of container applications have certain deficiencies. There are two mirror warehouse systems in the prior art, namely a centralized mirror warehouse system and an independent mirror warehouse system. ...
