All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "comprising" and "having," and any variations thereof, as appearing in the specification, claims and drawings of this application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. In addition, the terms "first", "second", and "third", etc. are used to distinguish different objects, and are not used to describe a particular order.
The following is a brief analysis of the related art to which the embodiments of the present application relate.
Mirror pull typically has the following characteristics: the time consumption of the process cannot be tolerated, namely the pulling process has strict requirements on low time consumption; the dependence on a mirror image warehouse is high, a mirror image cannot be pulled due to single-point failure of the mirror image warehouse, and a result that the mirror image cannot be deployed is finally obtained; the dependence on the network is high, for applications running on the edge device, such as an internet of things application program, the network connection between the edge device and the mirror image warehouse is intermittent, and the situation that the mirror image in the mirror image warehouse is pulled is usually blocked; and (4) rolling upgrading, which can cause application upgrading failure under the condition of mirror image pulling failure. Aiming at the characteristics, the related technology designs a local mirror image warehouse to carry out mirror image pulling cache, all mirror image requests pass through the local mirror image warehouse in the mode, and if the local mirror image warehouse has a corresponding mirror image, the mirror image of the local mirror image warehouse is used; and if the local mirror image warehouse does not have the corresponding mirror image, the corresponding mirror image is dragged from the public mirror image warehouse and is stored in the local mirror image warehouse. However, in the scheme based on the local mirror image warehouse, a large amount of computing resources and human resources are consumed in deploying, operating and maintaining the local mirror image warehouse, and the problem of rapid start of container application cannot be completely solved.
Based on the problems in the related art, an embodiment of the present application provides a mirror caching method, which can be implemented based on an application environment shown in fig. 1, please refer to fig. 1, where the application environment includes an electronic device 101 and a terminal device 102 connected to the electronic device 101 through a network. The terminal device 102 may be configured to send a mirror image cache request to the electronic device 101, where the cache request includes task configuration information of a mirror image cache task, and when the electronic device 101 receives the cache request, the format of the task configuration information is checked, and when the check is passed, a corresponding mirror image cache task is generated according to the task configuration information, and the mirror image cache task is added to a mirror image cache task queue. After determining that the target node successfully pulls the mirror image, the electronic device 101 may update the state of the mirror image caching task of the mirror image in the mirror image caching task queue to be successful, that is, complete the mirror image caching task.
For example, the electronic device 101 may be an independent server, or may be a cloud server that provides basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a web service, cloud communication, a middleware service, a domain name service, a security service, a Content Delivery Network (CDN), and a big data and artificial intelligence platform. The terminal device 102 may be a smart phone, a computer, a personal digital assistant, a kiosk, and so on.
Illustratively, a container orchestration platform is also deployed or operated in the electronic device 101 shown in fig. 1, and the method steps performed by the electronic device 101 may be specifically completed by the container orchestration platform. Referring to fig. 2, fig. 2 is a block diagram of a container arrangement platform according to an embodiment of the present disclosure, and as shown in fig. 2, the container arrangement platform includes an interactor and a controller, where the interactor includes an analysis module and a mirror image warehouse interaction module, the analysis module is configured to check and analyze a cache request sent from the outside, and after the check and the analysis are completed, deliver a corresponding mirror image cache task to the controller; the mirror image warehouse interaction module is used for interacting with the mirror image warehouse, and particularly used for acquiring a mirror image list and acquiring description information of a specified mirror image. The controller comprises a mirror image management module and a task management module, wherein the mirror image management module is used for monitoring whether a mirror image cache task to be executed exists in a mirror image cache task queue, if so, corresponding deployment arrangement is generated according to task configuration information of the mirror image cache task, for example, the deployment code can be that a corresponding node in the task configuration information pulls a corresponding mirror image of a corresponding mirror image warehouse, and an execution result of the mirror image cache task is returned under the condition that the mirror image pull is determined to be successful; the task management module is used for maintaining the mirror image cache task queue, classifying the tasks, for example, distinguishing the deleted mirror image and the cached mirror image, updating and recording the state and the execution result of the mirror image cache task, and executing a task retry mechanism. Based on the container arrangement platform, the mirror image pulling cache can be completed before the mirror image is used, so that time consumed by pulling the mirror image when the mirror image is used is saved, and the requirement of mirror image operation on high speed and real time can be met. Based on the application environment shown in fig. 1 and the container orchestration platform shown in fig. 2, the mirror caching method provided by the embodiment of the present application is described in detail below with reference to other drawings.
Referring to fig. 3, fig. 3 is a flowchart illustrating a mirror caching method according to an embodiment of the present application, where the method is applied to a container arrangement platform, as shown in fig. 3, including steps 301 and 303:
301: and acquiring a mirror image caching task, wherein the mirror image caching task comprises task configuration information of a mirror image to be cached, and the task configuration information comprises a target node for caching the mirror image to be cached.
In the embodiment of the application, the mirror image cache task usually exists in a mirror image cache task queue, the container arrangement platform can monitor the mirror image cache task queue in real time or at regular time, and when the mirror image cache task exists in the mirror image cache task queue, the mirror image cache task is extracted for execution. The mirror image caching task includes task configuration information of a mirror image to be cached, where the task configuration information includes a target node for caching the mirror image to be cached, related information of the mirror image to be cached, and related information of a mirror image warehouse, for example, as shown in fig. 4, the related information of the mirror image to be cached may include a name of the mirror image to be cached, a pull policy, and the like, the related information of the mirror image warehouse may include an address, an account number, and the like of the mirror image warehouse, and the target node may be a server and is identified by a node name or an IP (Internet Protocol) address.
The pulling policy of the mirror image to be cached may be IfNotPresent or Always, IfNotPresent indicates that the mirror image to be cached is pulled only when the mirror image to be cached does not exist on the target node (host), and Always indicates that the mirror image to be cached is pulled every time.
302: and generating deployment arrangement of the mirror image to be cached according to the task configuration information, wherein the deployment arrangement is used for indicating the target node to pull the cache mirror image from the mirror image warehouse for caching.
In the specific embodiment of the application, after the task configuration information of the mirror image caching task is acquired, corresponding deployment arrangement can be generated according to information such as a mirror image, a mirror image warehouse, a node and the like in the task configuration information. It should be understood that the orchestration refers to making an execution sequence of each action in a deployment process, a storage location and an acquisition manner of a dependent file required by the deployment process, and how to verify the success of the deployment according to a coupling relationship between deployed objects and dependencies of a deployed object environment, and the orchestration refers to performing orchestration-specified environment initialization on a target machine according to content and processes specified by the orchestration, storing specified dependencies and files, running specified deployment actions, and finally confirming the success of the joint deployment according to rules in the orchestration. In the container arrangement tool, there is a most basic arrangement mode, so that an application is operated as a container, and here, since only a pull cache of a mirror image to be cached is involved, the arrangement is mainly used for instructing a target node to pull a cache mirror image from a mirror image warehouse for caching, specifically, the arrangement may be used for instructing the target node to pull the cache mirror image from the mirror image warehouse according to a pull policy, for example, the target node is instructed to pull which mirror image from which mirror image warehouse, so that the container operation is only simple printing, and no substantial operation is performed.
303: and under the condition that the target node successfully pulls the mirror image to be cached, updating the state of the mirror image caching task to be successful.
In the embodiment of the present application, the container arrangement platform may update the state of the mirror image caching task in the mirror image caching task queue to be successful, for example, when it is determined that the target node successfully pulls the mirror image to be cached, for example, when receiving a prompt message that the pulling is successful or a prompt message that the caching is successful, which is returned by the target node.
For example, in the case that the target node does not successfully pull the mirror to be cached, the container orchestration platform may update the state of the mirror caching task to fail. Specifically, when the target node does not successfully pull the mirror image to be cached, the container arrangement platform re-executes the operations of obtaining the mirror image caching task and generating the deployment and arrangement of the mirror image to be cached according to the task configuration information, such as: and re-acquiring the task configuration information of the mirror image cache task from the mirror image cache task queue, and generating deployment arrangement of the mirror image to be cached according to the task configuration information, namely, indicating the target node to pull the cache image from the mirror image warehouse again for caching, and simultaneously increasing the number of times of success of non-pulling of the mirror image cache task once. If the number of times of the mirror image caching task which is not successfully pulled does not reach the preset number of times, continuing to execute the operations of obtaining the mirror image caching task and generating the deployment and arrangement of the mirror image to be cached according to the task configuration information until the number of times of the mirror image caching task which is not successfully pulled reaches the preset number of times (for example, 3 times), ending the mirror image caching task under the condition that the number of times of the mirror image caching task which is not successfully pulled reaches the preset number of times, updating the state of the mirror image caching task to be failed, and stopping executing the mirror image caching task. It should be appreciated that the reason for the mirror caching task failing execution may be that the mirror repository is unavailable, and so on.
Illustratively, before obtaining the mirror caching task, the method further comprises:
receiving a caching request of a mirror to be cached, generating a mirror caching task according to the caching request, and adding the mirror caching task to a mirror caching task queue;
and/or the presence of a gas in the gas,
and responding to the triggering of the timing task, generating a mirror image cache task according to the timing task, and adding the mirror image cache task to a mirror image cache task queue.
In this embodiment, the mirror caching task may be generated based on an external request, or may be generated by triggering a substantially local timing task.
Illustratively, the cache request includes a first task list of the mirror cache task, and the mirror cache task is generated according to the cache request, including:
checking the first task list;
under the condition that the first task list passes verification, analyzing the first task list to obtain task configuration information;
and generating a mirror image caching task according to the task configuration information.
Specifically, the first task list includes task configuration information of a mirror image to be cached, the container arrangement platform needs to verify the format of the task configuration information, if the verification is successful, the task configuration information is obtained, the mirror image caching task is generated, and if the verification is failed, the next task list is processed.
Illustratively, in response to the triggering of the timed task, generating a mirror cache task according to the timed task includes:
responding to the trigger of the timing task, and acquiring the list information of the mirror image to be cached and the list information of the target node;
integrating the list information of the mirror image to be cached and the list information of the target node into a second task list;
analyzing the second task list to obtain task configuration information;
and generating a mirror image caching task according to the task configuration information.
Specifically, the timing task is a task of executing mirror image pull cache at regular time, and when the timing task is triggered, the container arrangement platform acquires list information of the mirror image to be cached and list information of a target node, where the list information of the mirror image to be cached may include a name of the mirror image to be cached, a pull policy, a mirror image warehouse address, and the like, and the list information of the target node may include a name of the target node, an IP address, and the like. The container arrangement platform integrates the list information of the mirror image to be cached and the list information of the target node into a task list, namely a second task list, checks the format of the designated task configuration information in the second task list, analyzes the second task list if the checking is successful, obtains the task configuration information shown in fig. 4, and generates the mirror image caching task.
It can be seen that, by acquiring a mirror image caching task, the mirror image caching task includes task configuration information of a mirror image to be cached, and the task configuration information includes a target node for caching the mirror image to be cached; generating deployment arrangement of the mirror image to be cached according to the task configuration information, wherein the deployment arrangement is used for indicating the target node to pull the cache mirror image from the mirror image warehouse for caching; and under the condition that the target node successfully pulls the mirror image to be cached, updating the state of the mirror image caching task to be successful. Therefore, deployment arrangement of the mirror image to be cached is generated based on the mirror image caching task, then the target node pulls the mirror image to be cached for caching, and the purpose that the pulling cache of the mirror image to be cached can be completed before the mirror image to be cached is used can be achieved, so that time consumed by pulling the mirror image to be cached when the mirror image to be cached is used is saved, and the requirement of mirror image operation on high speed and real time can be met. In addition, because a large amount of computing resources and human resources are not consumed to deploy and operate and maintain the local mirror image warehouse, the embodiment of the application relatively weakens the dependence on the local mirror image warehouse and the network.
Referring to fig. 5, fig. 5 is a flow chart illustrating another mirror caching method provided in the embodiment of the present application, as shown in fig. 5, including steps 501 and 507:
501: judging whether a mirror image caching task exists or not and whether the times of the mirror image caching task which is not successfully pulled are less than preset times or not;
if yes, go to step 502, otherwise go to step 507;
502: acquiring a mirror image caching task;
