Description

Multi-scene compatible mirror synchronization method, device, equipment and medium
Technical Field
The present disclosure relates to the field of data processing technologies, and in particular, to a method, an apparatus, a device, and a medium for synchronizing images compatible with multiple scenarios.
Background
Today when software application architecture evolves into the cloud native architecture era, containers and images become an integral part of IT operation and development. The Container Image (Container Image) contains a packaged application and its dependencies, as well as the process information it runs at start-up, and contains all the dependencies required by the application.
Each application may be mirrored, or a version of each application may be mirrored, or even each mirrored needs another as a base mirror. Such a large number of images requires an image repository for storage management. One of the simplest and lightest components is the Registry that is officially pushed by the docker. It is a storage and content delivery system that can maintain several named container images, which can have different versions, and which itself supports TLS and Basic authentication for protection of the images.
However, when the mirror images in the Registry are managed, and the users of the project are controlled by more detailed authority, the public and private mirror image warehouse is distinguished, and this time, the Harbor is used. Harbor bottom-level image management encapsulates many scenarios that facilitate enterprise-level applications in terms of upper application layers by means of Registry capabilities, which provide role-based access control mechanisms, and organizes images and controls access rights through items. Particularly in a multi-tenant scenario, management and access control on multi-tenant mirror resources can be realized in a mode of combining tenants, nasspace and projects.
Container product management is still a problem that must be faced in current public, private, or hybrid cloud scenarios. When a development team issues a new version of a container image, it is synchronized relatively quickly to each cloud, or to a blind resource pool of the same cloud. Of course, for some well-known public cloud manufacturers, there is a set of mature and feasible schemes in the cloud environment, but the scheme is only suitable for the cloud environment of the public cloud manufacturers, and for the mixed cloud scene, the cross-cloud manufacturer scene needs to be additionally customized for the interface call. For the Harbor mentioned above, there is also a copy function for synchronizing images of different instances or different types of image warehouse, but network interworking of the synchronized image source end and the image synchronization end is required, and this scheme is limited when network non-interworking between different resource pools is encountered.
Therefore, how to realize mirror image data synchronization between different resource pools is a technical problem to be solved.

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flowchart of a first embodiment of a multi-scenario compatible mirror synchronization method provided in the present application.
As shown in fig. 1, the multi-scene compatible mirror synchronization method includes steps S101 to S103.
S101, when a central terminal monitors a mirror image synchronization event, acquiring current network reachable states of a mirror image source terminal and a mirror image synchronization terminal;
in an embodiment, when a user pushes a mirror image in one of the resource pools and triggers a mirror image synchronization event, the central end issues different synchronization operation instructions to the mirror image source end and the mirror image synchronization end according to the network reachable state of the mirror image synchronization end of the mirror image source end.
In an embodiment, after the deployment of each mirror resource pool is completed, the mirror resource pools can be managed to a central end, when each mirror resource pool is managed by the central end, network reachability between the mirror resource pool and other mirror resource pools of the central end can be tested, and a reachability topology graph between the mirror resource pools is constructed according to a test result. Network reachability status between each mirror resource pool pair by pair may be included in the reachability topology map.
In an embodiment, when a user uploads a new image at the image source end and triggers an image synchronization event, the central end may obtain current network reachability states of the image source end and the image synchronization end according to the reachability topology.
In one embodiment, the current network reachability status includes storage-side reachability, proxy-side reachability, and network-non-reachability.
The storage end can be a first storage end of the mirror image synchronization end and a second storage end of the mirror image source end which are in communication connection; the proxy server can be used as a first proxy server of the mirror image synchronization end and a second proxy server of the mirror image source end to be in communication connection; the network is not reachable as the mirror synchronization end and the mirror source end have no communication connection.
In an embodiment, when the mirror source and the mirror synchronization end can directly communicate through the data port of the storage end, that is, the mirror synchronization end can directly read mirror data from the storage end of the mirror source, the mirror source and the mirror synchronization end are reachable through the storage end.
In an embodiment, when two storage ends of the mirror source end and the mirror synchronization end cannot directly communicate, but the proxy server ends corresponding to the two storage ends can communicate, the two storage ends can realize data transmission through the proxy server end, and the two storage ends can be reachable through the proxy server end.
In an embodiment, when two storage ends corresponding to the mirror source end and the mirror synchronization end respectively cannot communicate with each other, and the proxy server ends corresponding to the mirror source end and the mirror synchronization end respectively cannot communicate with each other, that is, data transmission cannot be directly performed between the two storage ends, the two storage ends cannot be reachable by the network.
S102, the central terminal determines a mirror synchronous operation instruction corresponding to the current network reachable state according to a preset mirror synchronous operation table;
in an embodiment, when the communication modes between the mirror source end and the mirror synchronization end are different, the data synchronization process of the mirror data is also different, and the mirror synchronization operation instructions issued by the mirror source end and the mirror synchronization end are also different, so that a mirror synchronization operation table can be preconfigured according to the mirror synchronization operation instructions corresponding to different network reachable states, and when the current network reachable state between the mirror source end and the mirror synchronization end is determined, the corresponding mirror synchronization operation instructions can be queried in the mirror synchronization operation table according to the current network reachable state.
S103, according to the mirror synchronization operation corresponding to the mirror synchronization operation instruction, synchronously storing the target mirror data of the mirror source end to the mirror synchronization end so as to realize mirror synchronization.
In an embodiment, as shown in fig. 2, the central end issues an image synchronization operation instruction to the image source end and the image synchronization end (the resource pool a and the resource pool B), so that the image source end and the image synchronization end execute corresponding image synchronization operations, thereby copying and transmitting target image data from the image source end to the image synchronization end, and storing the target image data in a database of the image synchronization end to realize data synchronization of the target image data.
Further, when the current network reachable state is that the storage end is reachable, the target mirror image data is synchronously stored to the first storage end based on the communication channels of the first storage end and the second storage end so as to complete mirror image synchronization.
In an embodiment, if the mirror source end and the mirror synchronization end belong to the storage end intercommunication, only the storage end is required to synchronize the information of each layer of the mirror, and after synchronization is completed, the center end records the mirror information of the mirror synchronization end. This approach is among the most rapid and efficient ways.
Further, when the current network reachable state is that the proxy server side is reachable, transmitting the target mirror image data to the first proxy server side based on communication channels of the first proxy server side and the second proxy server side; after the first proxy server receives the target mirror image data, the target mirror image data is stored in the first storage end, so that mirror image synchronization is completed.
In an embodiment, if the mirror source end and the mirror synchronization end only belong to the proxy Agent end, the proxy Agent end of the target needs to pull the mirror from the proxy Agent end of the source and push the mirror back to the storage end of the target. The mode is less effective than the data transmission mode of the storage end because the mode is processed by two proxy ends and has performance loss in the process of pushing and pulling the mirror image again.
Further, when the current network reachable state is that the network is not reachable, transmitting the target mirror image data to the central end based on a communication channel between the central end and the mirror image source end; after the central end receives the target mirror image data, the target mirror image data is transmitted to the mirror image synchronization end based on a communication channel between the central end and the mirror image synchronization end and stored in the first storage end so as to complete mirror image synchronization.
In an embodiment, if the mirror source end and the mirror synchronization end are not in communication, the center end is required to execute a task to pull the mirror from the mirror source end and push the mirror to the mirror synchronization end. The mode has the best compatibility, but the mirror image needs to reach the center end from the mirror image source end and then reach the mirror image synchronous end from the center end, so that the efficiency is lower.
The embodiment provides a mirror synchronization method compatible with multiple scenes, which monitors mirror synchronization events of different mirror resource pools through a central terminal, acquires a current network reachable state between a mirror source terminal and the mirror synchronization terminal when the mirror source terminal triggers the mirror synchronization events, and determines a mirror synchronization operation instruction suitable for executing mirror data synchronization operation of the mirror source terminal and the mirror synchronization terminal according to a mirror synchronization operation table; and then according to the mirror image synchronization operation instruction, the target mirror image data is synchronized from the mirror image source end to the mirror image synchronization end, so that mirror image data synchronization among different mirror image resource pools can be realized, the mirror image synchronization method can adapt to mirror image synchronization schemes of various scenes, can synchronize mirror images in different environments, and can complete synchronization even if the synchronous source and the mirror image synchronization end are not communicated with each other as long as the synchronous source and the mirror image synchronization end can be simultaneously communicated with the central end, thereby improving the applicability and the reliability of the mirror image resource data synchronization method.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a multi-scenario compatible mirror synchronization method provided in the present application.
In this embodiment, based on the embodiment shown in fig. 1, the step S101 specifically includes:
s201, acquiring a first data port corresponding to the mirror image synchronous end and a second data port corresponding to the mirror image source end, wherein the first data port is a data communication interface of the first storage end, and the second data port is a data communication interface of the second storage end;
in one embodiment, when the network environment of one of the resource pools of the central side nanotube changes or triggers a mirror resource synchronization event, network reachability between the mirror source side and the mirror synchronization side can be retested.
In one embodiment, when testing network reachability between the mirror source and mirror sync ends, the testing may be performed in the order of storage, proxy, and hub.
In an embodiment, the proxy Agent end (i.e., proxy server end) and the storage end corresponding to the mirror source end and the mirror synchronization end both expose the Ping API to the outside, the API (Application Programming Interface ) has no actual service effect, only can be used for reachability test, and the API returns to obtain a Pong string as a response to indicate reachability communication.
S202, constructing communication connection between the first data port and the second data port, and obtaining a first communication connection result;
and S203, when the first communication connection result is that communication is reachable, determining that the current network reachable states of the mirror synchronous end and the mirror source end are reachable by the storage end.
In an embodiment, the central end informs the storage end-to-end of the address of the storage end-to-end through the Agent end, so that the storage end accesses the Ping interface of the opposite end, that is, the first storage end corresponding to the mirror synchronization end accesses the second storage end corresponding to the mirror source end, after the access is completed, the results are returned to the central end respectively, if the access is completed, the access direction is marked as the storage end is reachable, and the accessibility test is ended.
In an embodiment, if the network between the first storage end corresponding to the mirror synchronization end and the second storage end corresponding to the mirror source end is not reachable, that is, communication connection cannot be performed, a network reachability test of the proxy server end is performed.
Further, when the first communication connection result is that communication is not reachable, a third data port corresponding to the mirror synchronization end and a fourth data port corresponding to the mirror source end are obtained, wherein the third data port is a data communication interface of the first proxy server end, and the fourth data port is a data communication interface of the second proxy server end; constructing communication connection of the third data port and the fourth data port to obtain a second communication connection result; when the second communication connection result is that communication is reachable, determining that the current network reachable states of the mirror synchronization end and the mirror source end are reachable by the proxy server end; and when the second communication connection result is that communication is not reachable, determining that the current network reachable state of the mirror image synchronous end and the mirror image source end is that the network is not reachable.
In an embodiment, when the storage network reachability test result between the mirror source end and the mirror synchronization end is unreachable, the network reachability test of the proxy server end can be executed. And the central end respectively transmits the addresses of the proxy Agent ends of the opposite ends to the two proxy Agent ends, so that the proxy Agent ends access the Ping interface of the opposite ends, namely the third data port corresponding to the mirror image synchronous end accesses the fourth data port corresponding to the mirror image source end.
In an embodiment, after the access is completed, the results are respectively returned to the central end, if the access is available, the access direction is marked as the Agent end, if the access is not available, the access direction is marked as the local direction is not available, and the test is ended.
In an embodiment, the central end can issue reachability tests in two directions at a time, so that two reachability records can be generated, and the records are stored as reachability topology graphs according to the addresses of the mirror source end and the mirror synchronization end, wherein the reachability levels (including the reachability of the storage end, the reachability of the Agent end and the non-reachability of the Agent end) are stored in the central end and used as the basis for selecting a synchronization scheme when the central end executes a synchronization task according to a synchronization rule.
