detailed description

The present invention will be further described in detail below with reference to the specific embodiments thereof and the accompanying drawings. It is to be understood that the description is not intended to limit the scope of the invention. In addition, descriptions of well-known structures and methods are omitted in the following description in order to avoid unnecessarily obscuring the inventive concept.

It should be noted that, when the application server is migrated, the original server and the target server may be the same local area network or different local area networks. The application service migration under normal circumstances is all within the same LAN.

1 is a flow chart showing a seamless migration method of an application service based on a container technology according to the present invention.

As shown in FIG. 1, the container technology-based application service seamless migration method of the present invention includes:

Step S100: The original server receives an application service migration request sent by the user terminal, where the application service migration request includes location information of the application service to be migrated.

In this step, the user terminal sends an application service migration request to the original server, and the original server receives the application service migration request sent by the user terminal, where the application service migration request includes the location information of the application service to be migrated.

As an implementation manner of the present invention, the application service migration request records the type of the application service, the container and the container IP address where the application service is located, and the IP address of the server where the application service is located. It should be noted that the container is a container that is run on the server and virtualized by the docker technology. The application service refers to a service program running inside the container.

In step S200, the original server determines a corresponding original container based on the location information, generates a container image file of the original container corresponding to the application service to be migrated, and sends the container image file to the image warehouse, where the original container The container where the application to be migrated is located on the original server.

In this step, after receiving the application service migration request, the original server extracts the location information of the application service to be migrated from the application service migration request, determines the corresponding container according to the storage location information, and corresponding the application service to be migrated. The original container generates a container image file one-to-one, and sends the container image file to a mirrored warehouse for temporary storage, wherein the original container is a container where the application to be migrated is located on the original server. In the process of generating the container image file, a container will be mirrored, so that the IP address of the target container can be directly changed to the IP address of the original container, and the migration is convenient and seamlessly migrated.

Here, in order to ensure that the application service is normally shut down, all the applications to be migrated in the original server need to be stopped in batches. Specifically, before the step of generating the container image file by the original container corresponding to the application to be migrated, the method further includes: stopping all the application services to be migrated in the original server in batches.

In a cluster system, in order to ensure high availability of application services, usually one container may include multiple application services, and the same application service is dispersed in different containers. For example, a web application service provides a service for distributing web application services on multiple containers or multiple servers, so that when one container or server fails, another container or server can still provide the same kind of web service.

Step S300, the target server obtains the container image file from the mirrored warehouse, creates a target container based on the container image file, and changes the IP address of the target container to its original content. The IP address of the device.

In this step, the target server obtains the container image file from the mirrored warehouse, and further creates a target container one-to-one based on the container image file, that is, one container image file corresponds to one target container, and then the target container is The IP address is changed to the IP address of the original container corresponding to it. The container image file is a mirror made by docker technology. The container creation depends on a container image file. The container image file can be regarded as all running environments of the container, and the application service is running in the container. Here, in order to further ensure the successful migration, all the original containers corresponding to the application services to be migrated in the original server need to be stopped in batches. Specifically, before the step of the target server obtaining the container image file from the mirrored warehouse, the method further includes: stopping, according to the location information, all the originals corresponding to the application service to be migrated in the original server container.

Step S400, changing the IP address of the target server to the IP address of the original server.

In this step, in order to achieve seamless migration, it is necessary to change the IP address of the target server to the IP address of the original server.

Here, in order to further ensure the successful migration, it is necessary to stop the original server. Specifically, before the step of changing the IP address of the target server to the IP address of the original server, the method further includes: stopping the original server.

Finally, after the step of changing the IP address of the target server to the IP address of the original server, it is necessary to ensure that all application services migrated to the target server are successfully migrated. Specifically, after the step of changing the IP address of the target server to the IP address of the original server, verify whether all the application services to be migrated in the target server are successfully migrated.

In summary, a seamless migration method of application services based on container technology is introduced in detail. The present invention generates a container image file by sending the container image file to the original container corresponding to the application service on the original server, and then sends the container image file to the mirror warehouse temporarily. Save, the target server creates a target container based on the container image file obtained from the mirrored warehouse, and then changes the IP address of the target container to the IP address of the original container corresponding thereto, and finally changes the IP address of the target server to the original one. The server's IP address, through this migration, enables seamless migration of application services.

The container generates a container image file of the original container corresponding to the application to be migrated, and sends the container image file to the mirror warehouse, where the original container is a container where the application to be migrated is located on the original server. The original server 20 includes: a first processing module 21, configured to batch stop all the application services to be migrated in the original server.

For a detailed description of the module, refer to the aforementioned step S200.

The target server 30 is connected to the original server 20, and is configured to obtain the container image file from the mirror warehouse, create a target container based on the container image file, and change an IP address of the target container to be corresponding thereto. The IP address of the original container. The target server 30 further includes: a second processing module 31, configured to manually stop all the original containers corresponding to the application services to be migrated in the original server based on the location information.
