Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The node management method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein cluster node 102 communicates with server 104 over a network. The profile storage component may store data that the server 104 needs to process. The profile storage component may be integrated on the server 104 or may be placed on a cloud or other network server. When the cluster node 102 triggers a target event, the server 104 acquires node operation information reported by the cluster node; the server 104 searches the spam configuration file corresponding to the node operation information in the configuration file storage component according to the node operation information; when a spam configuration file corresponding to the node operation information exists, the server 104 verifies the node dependency relationship corresponding to the node operation information according to the node association relationship and the expected state description metadata contained in the spam configuration file to obtain a verification result; the server 104 returns a management result aiming at the node operation information according to the verification result; the management result is used to characterize whether the target event is executed. The cluster node 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and internet of things devices, which may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, etc. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.
In an exemplary embodiment, as shown in fig. 2, a cluster management method is provided, and an example of application of the method to the server in fig. 1 is described, including the following steps 202 to 206. Wherein:
step 202, when a target event is triggered, node operation information reported by a cluster node is obtained.
The target event may be an operation that the cluster node stops or scrolls up;
each cluster node is deployed with a cluster webhook (a callback interface based on the HTTP protocol) component, and a spam operation control component is deployed in a server.
In this embodiment, when a certain cluster node in the multi-cluster application triggers a target event, the cluster node reports the target event to a server through a cluster webhook component, and the server receives node operation content corresponding to the target event reported by the cluster webhook component in the cluster node through a spam operation control component. For example, during a rolling upgrade operation for a cluster node, the cluster node may need to stop and restart services on the cluster node, at which point the cluster webhook component actively reports node operation information occurring in the cluster node to a preset URL (Uniform Resource Locator ), i.e., a server.
Step 204, according to the node operation information, searching the spam configuration file corresponding to the node operation information in the configuration file storage component.
In the embodiment of the application, the server searches in the configuration file storage component of the server according to the node information contained in the received node operation information through the spam operation control component deployed by the server, and determines whether the configuration file storage component contains a spam configuration file corresponding to the node information. When the configuration file storage component does not contain the spam configuration file corresponding to the node information, the server releases the node operation, namely, the server returns a message of allowing the node operation to the cluster webhook component in the cluster node, and indicates the cluster node to allow the node to stop or roll upgrading operation.
Step 206, when the spam configuration file corresponding to the node operation information exists, verifying the dependency relationship between the nodes corresponding to the node operation information according to the node association relationship and the expected state description metadata contained in the spam configuration file, and obtaining a verification result.
In the embodiment of the application, when a spam configuration file corresponding to node operation information exists in a configuration file storage component of the server, a spam operation control component in the server reads node association relations and expected state description metadata stored in the spam configuration file. And verifying the dependency relationship between the nodes according to the read node association relationship and expected state description metadata and aiming at the association relationship between the cluster node reporting the node operation information and other cluster nodes, and obtaining a verification result corresponding to the node operation information, wherein the verification result reflects the management basis of the server for the node operation corresponding to the node operation information.
And step 208, returning a management result aiming at the node operation information according to the verification result.
Wherein the management result is used for representing whether the target event is executed.
In the embodiment of the application, the spam operation control component in the server determines whether the cluster node can execute the target event according to the verification result corresponding to the node operation information, obtains the management result corresponding to the node operation information, and returns the management result to the cluster webhook component of the cluster node to realize a spam management mechanism of the node for executing the target event for the cluster node.
In an alternative embodiment, if the server matches a plurality of spam configuration files related to the cluster node in the configuration file management component, the server determines that the management result is forbidden to operate when the spam configuration file with the verification result being verification failure exists; when the verification results of the plurality of spam configuration files are all verification passing, the server determines the management result as an allowed operation.
In an optional embodiment, a monitoring component may be further disposed in the server, and after the server completes the management of the target event through the spam operation control component, the management result is returned to the cluster node, and meanwhile, the management result may also be returned to the monitoring component through the spam operation control component, so as to monitor the spam operation control component, thereby facilitating maintenance.
In the node management method, when the target event is triggered, the dependency relationship between related nodes in the node operation information can be verified through the node operation information reported by the cluster nodes and the expected state description metadata in the spam configuration file, so that the management result aiming at the node operation information is obtained, the limitation of the node operation corresponding to the node operation information is realized, the service in the cluster is prevented from being unavailable due to the simultaneous stopping of multiple nodes, and the availability and the safety of the cluster service are further improved.
In an exemplary embodiment, the profile storage component includes node metadata, where the node metadata includes a node name, a node version, and a cluster in which the node is located corresponding to the spam profile, and step 204 includes step 2041. Wherein:
step 2041, in the node metadata of the spam configuration file, retrieving the node name, the node version and the cluster where the node is located corresponding to the node operation information, and determining the spam configuration file corresponding to the node operation information.
In this embodiment of the present invention, the spam configuration file in the configuration file storage component includes node metadata, which is used to uniquely identify the node involved in each spam configuration file, including the node name, the node version, and the cluster where the node is located, so when the server receives the node operation information reported by the cluster node, it can search according to the node name, the node version, and the cluster where the node is located in the node operation information, and the node metadata matches the same node name, the node version, and the cluster where the node is located in the node operation information, and further determines the search result of the node operation information in the configuration file storage component.
And when the search result is that the spam configuration file corresponding to the node operation information exists in the configuration file storage component, the current operation information is characterized as having corresponding constraint conditions. In contrast, when the search result is that the spam configuration file corresponding to the node operation information does not exist in the configuration file storage component, the fact that the association relation between the current operation information and other nodes does not exist is characterized, the cluster node is stopped, availability of cluster service in other cluster nodes is not affected, and therefore the server carries out 'release' processing on the target event corresponding to the node operation information.
In this embodiment, the node metadata is used to determine a spam configuration file corresponding to the node operation information, so that the node operation information can be retrieved, whether the spam configuration file corresponding to the node operation information exists in the configuration file storage component is determined, and further whether the node operation information affects other cluster nodes is determined, so that management of a target event corresponding to the node operation information is realized.
In one exemplary embodiment, the expected state description metadata contains node copy number, node operational state, and node deployment area constraints, as shown in FIG. 3, step 206 includes steps 302 through 308.
Wherein:
step 302, when a spam configuration file corresponding to the node operation information exists in the configuration file storage component, determining a target spam configuration file corresponding to the operated node according to the node operation information.
In the embodiment of the application, the spam configuration file in the configuration file storage component contains configuration metadata, which is used for uniquely identifying the spam configuration file and comprises a unique identification serial number and configuration expression information of the spam configuration file. When at least one spam configuration file corresponding to the node operation information exists in the configuration file storage component, a spam operation control component in the server reads the node name, the node version and the cluster where the node is located in the node operation information, and matches the node name, the node version and the cluster where the node is located in the spam configuration file of the configuration file management component to obtain a target spam configuration file corresponding to the operated node, wherein the target spam configuration file is used for verifying a target event, and the target event is a message reported to the server by the cluster node corresponding to the node operation information.
And step 304, determining the target cluster node according to the node association relation.
In this embodiment of the present application, the configuration file storage component includes a node association relationship corresponding to the spam configuration file, and the server may determine the target cluster node according to the node association relationship and the node operation information in the spam configuration file. The node association relationship is a single-phase dependency relationship, that is, the node A depends on the node B to be in a desired state, and the reverse direction is not established. For example, when the node a depends on the node B, and when the node a receives a request for stopping the node, the node a transmits node operation information to the server, and the server determines that the node B, which is the dependent node of the node a, can be determined according to the node operation information transmitted by the node a, and then the server determines the node B as the target cluster node.
Step 306, performing state verification on the state information corresponding to the target cluster node based on the node copy number, the node running state and the node deployment area constraint corresponding to the target cluster node in the target spam configuration file.
In the embodiment of the present invention, after the server determines the target cluster node, the server may obtain the expected state description metadata corresponding to the target cluster node according to the spam configuration file corresponding to the target cluster node, that is, the server may obtain the node copy number, the node running state and the node deployment area constraint of the target cluster node, where the expected state description metadata of the target cluster node reflects the state where the target cluster node is to be used as the dependent node of the operated node, and further, the server may perform the state verification of the target cluster node through the state information corresponding to the target cluster node and the expected state description metadata.
Optionally, the spam configuration file may include node association relationships and expected state description metadata corresponding to a plurality of cluster nodes, and the server may allocate the cluster nodes related to the spam configuration file according to the clusters.
And 308, determining the verification result as verification passing under the condition that the state information of the target cluster node meets the node copy number, the node running state and the node deployment area constraint.
In the embodiment of the present application, under the condition that the state information of the target cluster node satisfies the node copy book, the node running state (for example, whether the node is ready) and the node deployment area constraint, the server determines the verification result of the target cluster node as verification passing through the spam operation control component, and characterizes that the target event corresponding to the node operation information allows operation under the constraint condition of the current spam configuration file.
In this embodiment, a target cluster node is determined according to a node association relationship corresponding to node operation information, state verification is performed on the target cluster node according to a spam configuration file of the target cluster node, and a verification result of the node operation information is determined to pass verification under the condition that the state information meets the node copy number, the node operation state and the node deployment area constraint, so that management on a target event can be realized, and further safety and availability of cluster service are improved.
In an exemplary embodiment, step 208 includes step 2081. Wherein:
in step 2081, if the verification result is that the verification is passed, the management result for the node operation information is determined to be an allowed operation, and the management result is returned to the cluster node.
In the embodiment of the present application, when the verification result is that the verification passes, it is indicated that the number of node copies, the node running state and the node deployment area constraint of the dependent node of the operated node are satisfied, and the cluster service is not affected even if the operated node triggers the target event, so that the server determines the management result of the node operation information as an allowed operation, and returns the management result to the cluster node through the node operation control component.
And when the verification result is that the node fails, representing that the dependent node of the current operated node does not meet the node copy number, the node running state and the node deployment area constraint, if the current operated node triggers a target event, the current cluster service is not available, and at the moment, the server determines the management result as interception operation and returns the management result to the cluster node.
In this embodiment, the management result for the target event is determined according to the verification result corresponding to the node operation information, so that verification can be performed on the constraint of the node operation information on the availability of the cluster service, a spam management mechanism of the target event is realized, and the availability and security of the cluster service are improved.
In an exemplary embodiment, prior to step 202, the method further comprises:
and constructing a spam configuration file according to the configuration file management component aiming at the node metadata and the expected state description metadata, and storing the spam configuration file into the configuration file storage component.
In the embodiment of the application, a user may operate the spam configuration file in the configuration file storage component through the configuration file management component of the server, for example, the user may perform operations of checking, updating, deleting and adding the spam configuration file corresponding to the cluster node through the configuration file management component.
In addition, the server may construct a spam configuration file according to the node metadata and the expected state description metadata as file parameters in the spam configuration file corresponding to each cluster node, and store the configured spam configuration file to the configuration file storage component.
In this embodiment, the spam configuration file is constructed through the node metadata and the expected state description metadata, so that when the target event occurs in the cluster node, the target event can be verified by pulling the spam configuration file, and further a spam management mechanism for the target event is realized.
In an exemplary embodiment, as shown in FIG. 4, the method further includes steps 402 through 408.
Wherein:
in step 402, an update node is determined in response to an update operation of the spam configuration file.
In this embodiment, in a daily application of the multi-machine cluster service, when the cluster service updates or adds or deletes a cluster node, an update of a spam configuration file is required, and at this time, a user performs an update operation on the spam configuration file through a configuration file management component, and the server responds to the update operation of the spam configuration file, for example, the server first locates the update node, and determines that the added node or the deleted node is determined as the node name, the node version and the cluster where the node is located of the update node.
Step 404, determining a target spam configuration file corresponding to the updated node and a target spam configuration file corresponding to an associated node associated with the updated node according to the node metadata corresponding to the updated node.
In this embodiment of the present application, the server matches node metadata in the spam configuration file according to the node name, the node version, and the cluster where the node is located corresponding to the updated node, to obtain a target spam configuration file corresponding to the updated node, and at this time, the server reads the node association relationship recorded in the current spam configuration file, and if there is an associated node related to the updated node, determines the spam configuration file corresponding to the associated node as the target spam configuration file.
Step 406, updating each target spam configuration file to obtain a new spam configuration file according to the node association relation and the expected state description metadata corresponding to the updated nodes and the association nodes based on the configuration file management component.
In the embodiment of the application, the server updates the target spam configuration file by using the configuration file management component through updating the node association relation between the updated nodes and the association nodes and the expected state description metadata of the association nodes to obtain the updated new spam configuration file. For example, when a plurality of cluster nodes exist in the cluster for updating, the number of the cluster nodes is larger, and the number of the updated nodes is also larger, at this time, the server can determine the node association relationship and the expected state description metadata corresponding to the updated nodes and the associated nodes according to the description file corresponding to the updated nodes, so as to automatically update the target spam configuration file and obtain a new spam configuration file.
Step 408, store the new spam profile to the profile store component.
In the embodiment of the application, after the server completes updating the target spam configuration file, the new spam configuration file is stored in the configuration file storage component.
In this embodiment, the server automatically updates the target spam configuration file according to the node association relationship and the expected state description metadata of the update node and the association node, so that the update efficiency of the spam configuration file corresponding to the update node can be improved when the cluster node is updated.
In an exemplary embodiment, as shown in fig. 5, an example of a node management method is provided, including steps 501 to 506. Wherein:
step 501, a server constructs a spam configuration file according to a configuration file management component and stores the spam configuration file into a configuration file storage component;

step 503, when triggering a target event, the cluster node reports node operation information corresponding to the target event to a server, and the server determines a management result of the target event corresponding to the node operation information according to the spam configuration file;
step 504, the server exposes the spam configuration items of the spam configuration file for the cluster API through the spam operation control component;
Step 505, the cluster node receives the management result, and realizes the management of the cluster node according to the management result;
in step 506, the server reports the management result to the monitoring component through the spam operation control component.
