the encapsulation package is parsed to extract the added image therefrom.
In some embodiments, pushing the added image to the image repository includes:
constructing a working environment of the mirror image warehouse, and logging in the mirror image warehouse based on the working environment;
determining whether an item to which the added image belongs already exists in the image repository;
uploading the added image under the item to the image repository in response to the item already existing in the image repository;

In some embodiments, further comprising: the deleted image is marked as unavailable in the database in response to receiving a delete image request from the client.
In some embodiments, further comprising: the data from which the image was deleted is further deleted from the image repository.
In some embodiments, further comprising: and in response to receiving a query mirror request from the client, retrieving the metadata and the tags based on the query condition selected by the client, and feeding back the retrieval result to the client to be visually shown.
The following further illustrates embodiments of the invention in accordance with the specific example shown in fig. 2.
As shown in fig. 2, the overall framework of mirror image management is that a client may perform operations related to adding, deleting, and querying a mirror image, and a mirror image management server may respond to the corresponding operations, and when the client sends a request for adding a mirror image, the mirror image management may operate a connection docker service (container service engine) and a Harbor warehouse (mirror warehouse), and update the contents of the database; and the request for deleting and inquiring the mirror image performs relative operation on the database, and a corresponding response is made to the client after the request is completed.
Mirror images are added by dockerhub (container terminal) see fig. 3. Downloading the mirror image through a dockerhub website and uploading the mirror image to a harbor warehouse, connecting a mirror image management server to docker service after clicking to add the mirror image through the dockerhub, logging in through the input dockerhub account and the password, and inputting the mirror image to be downloaded and the name to be stored; and the server side pulls the mirror image, marks the mirror image and uploads the mirror image to the mirror image warehouse.
The flow of uploading the image to the harbor repository via a local upload tar package (a compressed encapsulation) is shown in figure 4. After the mirror image is uploaded through the local uploading tar packet, the mirror image management server is connected with the docker service, analyzes the uploaded tar packet file data, acquires the mirror image, marks the mirror image, and uploads the mirror image to the hardor warehouse.
The images uploaded by the dockerhub and tar packets are finally uploaded to a hardor warehouse for unified management, and the specific process of uploading to the hardor is shown in fig. 5: after a server builds a harbor environment, the mirror image uploaded to the harbor can be visually managed; in the uploading process, firstly logging in a harhor, judging whether an item to which an uploading mirror image belongs exists or not, if not, creating the item, and then uploading the mirror image to a harbor warehouse; and after the user logs in through inputting the address of the hardor warehouse at the page end, the uploaded mirror image can be managed.
In addition, when a certain mirror image is determined not to be needed, the mirror image can be deleted through a delete button; in order to facilitate the data recovery, the invention adopts a soft deletion measure, namely the mirror image in the hardor warehouse is not deleted, and the mirror image in the database is placed in an unavailable state.
The mirror images under a plurality of scenes may exist at the same time, a user can query the required mirror images according to conditions such as mirror image types, mirror image names, labels and the like, and the mirror image management server screens relative data in the database according to query conditions selected by the user at the client and feeds the data back to the client for display.
As can be seen from the foregoing embodiments, in the mirror management method provided in the embodiments of the present invention, the position of the added mirror is extracted from the mirror adding request; pulling the added mirror image from the position by using a container service engine, setting a label for the added mirror image and pushing the label to a mirror image warehouse; the metadata and the label of the added mirror image are stored in the database, and the available technical scheme of the added mirror image is marked in the database, so that the mirror image of the virtual machine container can be effectively managed, and the availability and the usability of the container are improved.
It should be particularly noted that, the steps in the embodiments of the mirror image management method can be mutually intersected, replaced, added, or deleted, so that these reasonable permutation and combination transformations should also belong to the scope of the present invention for the mirror image management method, and should not limit the scope of the present invention to the described embodiments.
