Description

 Mirror synchronization method, system, device and storage medium of mirror warehouse

This application claims the priority of the Chinese Patent Application filed on Dec. 29, 2017, the Chinese Patent Application No. PCT Application No. In the application.

Technical field

The present application relates to the field of Docker technology, and in particular, to a mirror synchronization method, system, device and storage medium of a mirror warehouse.

Background technique

Docker (Docker Is an open source application container engine that allows developers to package their applications and dependencies into a portable container and then publish them to any popular Linux On the machine, virtualization can also be implemented. The container technology provided allows several containers to be run on the same host or virtual machine, each container being a separate virtual environment or application.

Container from Docker Image, which can be generated by the user or submitted by the running container. After the image is generated, it can be pushed to the image repository for saving, or pulled from the mirror repository. Go to the local to run the container.

Docker provides an official image repository (Docker hub), while allowing users to build their own private image repository (private Registry). For most organizations and organizations, it is necessary to use a private image repository to protect the mirrored content and use of the repository.

Mirrors are stored in the file system as tiered storage. Different images may share some layers to save storage space. For warehouse construction involving multi-regional user access, mirror synchronization is a must-have when unified management of the image is required to ensure that the scope of the image used by the user is not limited to a certain area.

Mirror synchronization can be implemented by multiple schemes, one of which is shared storage, that is, a registry of multiple areas mounts a shared network storage disk, so that each time a mirror is pushed to a certain area of the registry. All the warehouses are immediately synchronized. However, sometimes the multi-region registry cannot share storage, and the networks between the regions cannot access each other, that is, the regions are isolated.

When using a Docker image in a multi-tenant environment, users under the tenant are typically restricted to access only the mirrored repository deployed in the public service area of each Availability Zone. For public mirroring, you need to synchronize in the mirrored warehouse of each available area; for private mirrors inside the tenant, you also need to synchronize the mirror to each available area. For the user, the images in each available area that they can see should be consistent, while the cloud storage of each available area cannot be shared across areas, and the mirrored events cannot be distributed to other available areas, so the shared storage cannot be used. The way to achieve synchronization, and only use real-time synchronization.

Detailed ways

The present application provides a mirror image synchronization method and system for a mirrored warehouse. The objects, technical solutions, and advantages of the present application will be more clearly and clarified, and the present application will be further described in detail below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

Please refer to FIG. 1 , which is a flowchart of a preferred embodiment of a mirror synchronization method of a mirrored warehouse provided by the present application. As shown in FIG. 1 , the mirror synchronization method of the mirror warehouse according to the preferred embodiment of the present application has the following steps:

S100. The host client in the available area initiates a data access request to the cloud management area warehouse through the proxy server of the available area.

In this embodiment, a cloud management area and a plurality of available areas are set in the system, and the cloud management area is a centralized management area, and a cloud management area warehouse is deployed in the cloud management area, and is configured to manage all the mirrors, and each available area passes the proxy. The server accesses the cloud management area warehouse, wherein each of the available areas is deployed with a set of proxy servers, and the host client of an available area can only access the cloud management area warehouse through the proxy server of the available area, wherein the proxy server is an Nginx proxy server. Each available area can be set in different locations, such as Beijing, Shanghai, and Shenzhen. Each available area can communicate with the cloud management area, but each available area is isolated from each other. This application does not have a mirror in each available area. The warehouse, but the proxy server is set in each available area, and the host clients of each available area access the cloud management area warehouse through the proxy server, thereby realizing the unified management of the mirror, so no cross-region mirror synchronization is required, and the deployment is saved. Cost, and does not result in mirroring due to the original Availability Zone Image Repository Issue caused the problem can not be synchronized.

Preferably, before step S100, the method further includes: receiving, by the host client in the available area, a mirroring event initiated by the user terminal of the available area, and generating a data access request according to the mirroring time, wherein the mirroring event includes a mirroring push event and Mirror pull event.

During the specific implementation, the user terminal initiates a mirroring event to the host client in the available area, specifically, pushing the image to the host user of the available area or initiating the image pull request, and the host client in the available area receives the image event and determines The mirroring event is a mirroring event or a mirroring event, and generates a data access request. If it is a mirroring push event, the image is pushed to the cloud management area warehouse through the proxy server. If the image is pulled, the image is accessed through the proxy server. Warehouse, pull the required image from the cloud management warehouse.

In a further embodiment, as shown in FIG. 2, the step S100 includes:

Step S101: The host client in the available area accesses the proxy server of the available area by using a domain name;

Step S102: The proxy server performs secure transport layer protocol authentication according to the domain name, and sends the data access request of the host client to the cloud management area warehouse after the verification is passed.

During specific implementation, the host client in the available zone accesses the proxy server of the available zone through the domain name, and the DNS server resolves the domain name to the proxy server, and then the proxy server performs secure transport layer protocol verification (TLS authentication), and after the verification is passed, The data access request is forwarded by the proxy server to the cloud management area warehouse, wherein the domain name, the certificate, and the key used by the proxy server of each available area are the same, and the certificate and the key pair are generated according to the domain name and the like, and when performing TLS verification, That is, if the verification certificate and the key pair are correct, and the verification is successful, the cloud management area warehouse can be accessed through the proxy server. This application sets the domain name, certificate, and key of the proxy server of each available area to be consistent, thereby making each available area The domain name accessed by the host client is the same, and there is only one TLS certificate key pair. The actual mirror storage is only one, so the consistency of the system is guaranteed.

Step S200: The cloud management area warehouse parses the data access request, and when determining that the data access request is a mirror push request, notifying the host client of the available area to push the image to the cloud management area warehouse through the proxy server; determining that the data access request is a mirror When pulling the request, pull the required image from the cloud management area repository to the available area.

In this embodiment, the mirrored warehouse of the cloud management area parses the data access request when receiving the data access request of the proxy server, performs corresponding operations according to the request type, and notifies the available area when the access request is a mirror push request. The host client pushes the image to the cloud management area warehouse through the proxy server. After the host client of the available area pushes the image to the cloud management area warehouse, the other available areas can directly invoke the pushed image from the cloud management area. Specifically, When the host client in Shenzhen pushes an image through the proxy server in the area, the cloud management area warehouse stores the image. If the other area needs to invoke the image, for example, the user terminal in Beijing needs to invoke the image, then the host in the Beijing area The client can initiate a mirror pull request to the cloud management area warehouse through the proxy server in the area, so that the host client in the Beijing area can directly pull the image pushed by the Shenzhen area from the cloud management area warehouse.

Further, the data access request includes at least a specific number of the available area and a type of the access, and the type of the access includes a mirror push and a mirror pull. In the specific implementation, each available area is preset with a number. For example, the Shenzhen area is set to 001, the Guangzhou area is set to 002, and so on, and the number of each of the available areas is inconsistent, so that the cloud management area warehouse cannot determine which available area to send the data access request.

When the host client generates the data access request, the specific number of the host client needs to be placed in the data access request. In addition, in order to avoid malicious access to the cloud management area warehouse, the cloud management area warehouse needs to initiate The host client is authenticated. In a preferred embodiment, the data access request further carries a user name and a password, and the user terminal accesses the host client of the available area by using the login user name and password, and the host client uses the user. The name and password are placed in the data access request, packaged and sent to the proxy server, and then further sent to the cloud management area warehouse through the proxy server.

After the host client sends the data access request to the cloud management area warehouse through the proxy server, the cloud management area warehouse first decodes the data access request, verifies the user name and password in the data access request, and reads the data after the verification is passed. Accessing the available area number in the request, and then determining the type of the data access, and analyzing whether the data access request is reasonable. In the specific implementation, the cloud management area warehouse is provided with a control unit, and the cloud management area warehouse is controlled by the control unit. The data access request decodes and verifies the username and password and determines the type of the data access request. When determining the mirror push request, the cloud management warehouse sends a data push notification to the host client of the corresponding numbered Availability Zone, the host client is After receiving the data push notification sent by the cloud management area warehouse, the image can be pushed to the cloud management area warehouse through the proxy server.

In a further embodiment, when the host client sends a mirror pull request to the cloud management area, the data access request further needs to carry the type and name of the image to be pulled, and the cloud management area warehouse is further Split into multiple mirrored storage units that store different types of mirrors. After the control unit of the cloud management area warehouse parses the type and name of the image to be pulled, first finds the image storage unit that stores the image of the type, and then traverses the image storage unit, if the name of the image to be pulled is found. , the image is pulled to the host client of the available area for sending the request, and is delivered by the host client to the user terminal; if the name of the image to be pulled is not found, the prompt message is sent to the host client through the proxy server. Prompt the host client to have no such mirror and verify that the name of the mirror is correct.

When the host client accesses the cloud management area warehouse, the application authenticates the host client, ensures data security of the cloud management area warehouse, avoids malicious access of the cloud management area warehouse, and avoids the cloud management area by processing each available area number. The name of the Availability Zone for sending data access requests cannot be known, ensuring normal mirror synchronization.

Compared with the existing image synchronization method, the present invention does not need to have a mirrored warehouse in the available area and the cloud management area. When performing mirror synchronization, the mirror synchronization consumes less time, and does not need to pass user push, notification, and cloud management area components. Call Docker API pull image, cloud management area component calls Docker The API pushes the image to the various Availability Zones, and since there is no need to push the image to the cloud zone in an available zone and then push the image to each Availability Zone, there is no probability of failure due to the native notification mechanism of the cloud zone warehouse. After the push mirror is sent, the notification is not sent, causing the problem that synchronization cannot be started. In addition, since there is only one centralized mirror library, there is no problem of mirror synchronization loopback.

Please refer to FIG. 3 , which is a flowchart of a preferred embodiment of step S200 in the image synchronization method of the mirror warehouse provided by the present application.

As shown in FIG. 3, the step S200 includes:

Step S201: The cloud management area warehouse receives a data access request sent by the proxy server and parses the data access request;

Step S202, determining whether the data access request is a mirror push request or a mirror pull request;

Step S203: If the data access request is a mirror push request, notify the host client of the available area to push the image to the cloud management area warehouse through the proxy server; if the data access request is a mirror pull request, find the image required by the request, and pass the The proxy server that sent the request pulls the image into the host client of the Availability Zone where the proxy server is located.

In this embodiment, when the host client of the available area accesses the cloud management area warehouse, the data access request is sent to the mirrored warehouse through the proxy server, and the cloud management area warehouse pulls the stored image to the available area. The mirror is sent to the host client of the available area through the proxy server, and then the host client feeds back to the user terminal, and the mirror of all the available areas is uniformly managed by adopting a mirror library, so that the warehouse push is not caused by the available area. The image is not sent out and the problem cannot be synchronized. You do not need to push the image to the cloud zone warehouse in an available area, and then synchronize the image to all available areas. You only need to store the image. When the zone needs to be called synchronously, it only needs to access the cloud management zone to obtain the image. The synchronization method is simple and the system consistency is ensured.

In a further embodiment, the mirror synchronization method of the mirror warehouse further includes:

When the proxy server pushes the image to the cloud management area warehouse or the cloud management area warehouse to pull the image to the proxy server, the proxy server analyzes the size of the mirrored data, and prompts the mirror transmission failure when the mirrored data is larger than the upper limit of the data size preset by the proxy server. .

In this embodiment, since the default size of the request data is small (1M) after using the Nginx proxy server, and some mirror layers are larger (about 100+M) when the image is pushed, the pushed image passes through the proxy server. At the same time, the size of the mirrored data needs to be analyzed. When the mirrored data is larger than the upper limit of the data size preset by the proxy server, the image transmission fails. In this case, the user can modify the configuration of the Nginx proxy server to set the size of the preset request data. The upper limit is set to infinity to continue the transfer.

In a preferred embodiment, the number of available zones is at least one, and each of the available zones is deployed with a set of proxy servers, and the host clients of each available zone access the cloud zone warehouse through the proxy servers of the available zones.

Further, the domain name, the certificate, and the key of the proxy servers in the respective Availability Zones are the same, so that the domain names accessed by the host clients of the available zones are the same, and only one copy of the TLS certificate key pair is used. There is only one mirror storage, so the consistency of the system is guaranteed.

This application provides a unified management method for mirroring. There is only one centralized mirror library, which has the following advantages: because there is only one mirror library, there is no need to perform any cross-region mirror synchronization, avoiding the synchronization of mirroring by other methods. Various problems. The domain name of the mirror library accessed by all hosts in all areas is the same. There is only one TLS certificate key pair, and there is only one actual mirror storage, which maintains the consistency of the system. Only the centralized management area needs to deploy a Registry (mirror repository) to store the image. In other areas, only one proxy server needs to be deployed, which saves deployment costs.

The application also provides a mirror synchronization system of a mirror warehouse. As shown in FIG. 4, the device includes:

A plurality of Availability Zones 1, including a Host Client 11 and a Proxy Server 12, the Host Client 11 being arranged to initiate a data access request to the cloud zone repository through the proxy server 12 of the Availability Zone, the proxy server 12 being configured to The host client 11 and the cloud management area warehouse establish a connection;

The cloud management area warehouse 2 is configured to parse the data access request, and when determining that the data access request is a mirror push request, notify the host client 11 of the available area to push the image to the cloud management area warehouse 2 through the proxy server 12, When the data access request is a mirror pull request, the required image is pulled from the cloud management area repository 2 to the available area for sending the request. For details, please refer to the corresponding embodiment of the above method.

In the mirror synchronization system of the mirror warehouse of the present application, the host client 11 is further configured to receive a mirroring event initiated by a user terminal of an available area where the host client 11 is located, and generate a data access request according to the mirroring time, where the mirroring Events include mirror push events and mirror pull events. For details, please refer to the corresponding embodiment of the above method.

The data access request of the end is sent to the cloud management area warehouse. For details, please refer to the corresponding embodiment of the above method.

In summary, the present application uniformly manages the mirroring of the available area by setting a centralized mirror warehouse in the cloud management area, so that no cross-area mirror synchronization is required, and the synchronization is achieved by other methods. The various problems will not cause the problem that the mirrors pushed by the available area mirror library are not sent out, and only a mirrored warehouse is deployed in the cloud management area. Only one proxy server needs to be deployed in each free area, saving Deployment costs. The private image inside the tenant can also be synchronized to each available area in time, so that in any available area, the user has no indiscriminate access to the public image and the user under the tenant for the private image inside the tenant.
