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, including the persistence methods of single database and database cluster. For a single database, the following steps are included: 1. Build the requested database mirror; 2. Parse the database service creation parameters; 3. Create a ceph block device; 4. Create a database container, etc.; 5. Create an entry access container. The database cluster includes the following steps: 1. Parse the database service creation parameters; 2. Create a ceph block device; 3. Register the entry access service; 4. Create the entry access container; 5. Register the database service; 6. Create the database container. The swarm-based database service persistence system of the present invention includes: an analysis module; a control module; a network module; a registration module and the like. The invention provides a general persistence method for the database service, and improves the usability of the database service and the security of data.

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...
