Problems solved by technology

[0004] If all data in the running process of Container Service is not persisted, if the container instance is stopped or deleted or exits abnormally, the data will be lost and cannot be retrieved.
However, for the swarm container cluster management platform, there is no general database service, including a single database and a database cluster persistence method and system

Embodiment

[0053] Such as figure 1 As shown in the figure, it shows the swarm-based database service persistence system, which mainly includes: control module, analysis module, registration module, network module, and resource management module.

[0054] In this embodiment, the control module is responsible for receiving the request for creating a database sent by the user. After the module receives the request, it forwards it to the parsing module for parameter analysis, and then the control module forwards the parameters including network drivers and network names to the network module to create a network. , and then forward the parameters including block device size, block read and write permissions, block device name, block device pool name, etc. to the resource management module to request a block device, and finally call the docker api to create a container and return it to the user.

[0055] In this embodiment, the parsing module is responsible for the request from the user of the...

Abstract

The invention discloses a database service persistence method based on swarm. The database service persistence method comprises a single database and a persistence method of a database cluster. For asingle database, the method comprises the following steps: 1, constructing a requested database mirror image; 2, analyzing database service creation parameters; 3, creating ceph block equipment; 4, creating a database container and the like; And 5, creating an entrance access container. The database cluster comprises the following steps: 1, analyzing database service creation parameters; 2, creating ceph block equipment; 3, registering an entrance access service; 4, creating an entrance access container; 5, registering a database service; 6, creating a database container. The database servicepersistence system based on the swarm comprises an analysis module, a database service persistence module and a database service persistence module, a control module; a network module, a registrationmodule and the like. The invention provides the universal persistence method for the database service, so that the availability of the database service and the security of data are improved.

Description

technical field [0001] The invention relates to the technical field of containers, in particular to a swarm-based database service persistence method and system. Background technique [0002] Docker is currently one of the most popular open source projects in the field of container technology. The docker container can provide developers with packaging applications and related dependencies into portable containers. Compared with virtual machines with similar resource isolation, containers Virtualizes the OS rather than the hardware, so it's more portable and efficient, booting up almost instantly. Swarm is one of the most popular container cluster management tools for docker, and it is an orchestration tool native to docker. It mainly abstracts several docker hosts into a whole, and manages various docker resources on these docker hosts through one entry. [0003] Ceph is currently one of the most mainstream open source storage projects. It is a reliable, automatic rebalanc...
