Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
FIG. 1 is a system architecture diagram illustrating a multi-cluster deployed with applications, according to an example embodiment.
As shown in fig. 1, a plurality of clusters 11 may be provided for service requirements or disaster recovery backup requirements, and applications may be deployed in each cluster 11. If the application deployment adopts the container technology, a container is set in the cluster, and the application is containerized.
In this system architecture, after the system receives traffic for accessing the application, the traffic is forwarded to one of the clusters 11 randomly through the intelligent DNS. An ingress controller (Ingress Controller) is provided in each cluster 11, and after traffic enters the clusters 11, the traffic is forwarded by the ingress controller in the cluster 11 to nodes (Pod) in the cluster 11.
However, this approach cannot set the access traffic rules across multiple clusters, and cannot control traffic access to each cluster according to a unified rule.
In order to solve the technical problem, in the scheme provided by the disclosure, an inlet controller independent of each cluster is provided, and the inlet controller can determine which cluster to forward the traffic to and which node of the cluster to forward the traffic to based on a preset traffic distribution rule, so that the accessed traffic can be uniformly forwarded, and the unified management of the traffic of multiple clusters with applications deployed by the access by the user is satisfied.
Fig. 2 is a flow chart illustrating a method of configuring a multi-cluster deployed with an application according to an exemplary embodiment of the present disclosure.
As shown in fig. 2, the configuration method of multiple clusters deployed with applications provided by the present disclosure includes:
Step 201, acquiring a configuration file corresponding to an application to be distributed and a preset cluster list; the configuration information is used for indicating a traffic distribution rule, the cluster list comprises cluster information, and nodes in the cluster indicated by the cluster information are used for deploying the application.
The scheme provided by the disclosure can be used in an application deployment platform, the deployment platform can be arranged in a cluster and also can be arranged in user equipment, and a user can operate in the platform to configure the cluster for deploying the application.
The applications deployed in the cluster may provide application services, and in particular, may be deployed in each node in the cluster. When a corresponding application program is set in the terminal equipment, the terminal equipment can use the function provided by the application service, specifically, the request sent by the terminal equipment can be distributed to the nodes of the cluster, the nodes process the request according to the deployed application, and the processing result is fed back to the terminal equipment.
In particular, when an application is deployed in multiple clusters, the clusters may be configured.
Further, when the multi-cluster is configured, a configuration file of the application to be distributed can be obtained, and the configuration information is used for indicating the traffic distribution rule. For example, forwarding traffic randomly, for example, forwarding traffic according to a load condition of the cluster, for example, forwarding traffic according to gray scale test information.
In practical application, the configuration file may be set by a user according to requirements, for example, may include a rule that traffic is forwarded to a cluster, and may also include a rule that after the traffic is forwarded to the cluster, the traffic is forwarded to a node in the cluster.
When the multi-cluster is configured, a preset cluster list corresponding to the application to be distributed can be obtained. The cluster list comprises cluster information, and nodes in the clusters indicated by the cluster information are used for deploying the application.
Specifically, the user may set a cluster list of the application to be published according to the requirement, where a plurality of cluster information, such as a cluster identifier, is recorded in the cluster list. For example, if the identification of the first cluster, the identification of the second cluster, and the identification of the third cluster are included in the cluster list, the characterization requires that the application to be deployed into the three clusters, and therefore, the three clusters need to be configured.
Step 202, generating an inlet controller according to the configuration file and cluster information included in a cluster table; the ingress controller is configured to receive the traffic and forward the traffic to a destination node of a destination cluster corresponding to the traffic, where the destination cluster is any one of the clusters.
Further, an ingress controller may be generated in the platform. After the application to be deployed is deployed, the ingress controller is configured to forward traffic of the application to a node in the cluster, so that the traffic is responded by the application deployed in the node.
In practical application, the inlet controller can be generated according to the configuration file and cluster information included in the cluster table. For example, the traffic distribution rule may be determined according to information in the configuration file, and the information of the clusters and nodes capable of receiving the traffic may be determined according to the cluster information, so that the ingress controller is generated according to the rules. The ingress controller can forward the received traffic to any cluster indicated by the cluster information according to the traffic distribution rule, and specifically to any node of the cluster where the application is deployed.
Fig. 3 is a system architecture diagram of a multi-cluster deployed with applications, as shown in an exemplary embodiment of the present disclosure.
As shown in fig. 3, there are a plurality of clusters 31 in the system architecture, each cluster includes a plurality of nodes, and applications are deployed in the nodes, for example, app1 may be deployed and App2 may also be deployed.
The method provided according to the present disclosure may generate an ingress controller from a deployed application.
In one embodiment, an ingress controller may be generated for forwarding traffic for App1, and an ingress controller may also be generated for forwarding traffic for App 2. After receiving the flow of App1, the system may forward the flow to the ingress controller 32 by the intelligent DNS, and then forward the flow to the node of the cluster by the ingress controller corresponding to App1, and after receiving the flow of App2, the system may forward the flow to the ingress controller corresponding to App2 by the intelligent DNS, and then forward the flow to the node of the cluster by the ingress controller corresponding to App 2.
In another embodiment, only one ingress controller may be generated, and the flow forwarding rule of each App may be written into the ingress controller, so that the ingress controller may perform forwarding processing on the flows according to the flow forwarding rule of each App.
The method for configuring the multi-cluster deployed with the application comprises the steps of obtaining a configuration file corresponding to the application to be deployed and a preset cluster list; the configuration information is used for indicating a flow distribution rule, the cluster list comprises cluster information, and nodes in a cluster indicated by the cluster information are used for deploying the application; generating an inlet controller according to the configuration file and cluster information contained in a cluster table; the ingress controller is configured to receive the traffic and forward the traffic to a destination node of a destination cluster corresponding to the traffic, where the destination cluster is any one of the clusters. In the embodiment, the inlet controllers independent of the clusters are arranged, so that the flow can be controlled according to the unified rule, the flow can be forwarded in a unified way, and the requirement of a user on unified management of the flow of the access multiple clusters can be met.
Fig. 4 is a flow diagram illustrating a method of configuring a multi-cluster deployed with an application according to another exemplary embodiment of the present disclosure.
As shown in fig. 4, the configuration method of multiple clusters deployed with applications provided by the present disclosure includes:
step 401, obtaining a preset cluster list corresponding to an application to be deployed.
Step 401 is similar to the manner of obtaining the cluster list in step 201, and will not be described again.
Step 402, obtaining a service configuration file and an entry configuration file corresponding to an application to be deployed, wherein the entry configuration file is a rule for distributing traffic to a cluster, and the service configuration file is a rule for forwarding traffic received by the cluster to nodes in the cluster.
When the cluster is configured, a service configuration file corresponding to the application to be distributed can be acquired, and the service configuration file is acquired. The service profile and the portal profile corresponding to the application to be deployed may be set in advance according to the requirements.
Specifically, the service profile may be, for example, service yaml, in which a rule for forwarding traffic received by the cluster to a node in the cluster is recorded, and the user may set the service profile according to the requirement.
Further, the entry profile may be, for example, ingress yaml, in which a rule is recorded that forwards the received traffic to any one of the clusters, and the user may set the entry profile according to the requirement.
In this embodiment, the user may set the traffic distribution rules according to the requirements, and then may generate the ingress controller according to the rules, where the ingress controller may forward the traffic according to the rules, so as to forward the traffic according to the unified rules.
Step 403, determining a traffic forwarding rule according to the rule of distributing traffic to the cluster and the rule of forwarding traffic received by the cluster to nodes in the cluster.
The platform can combine the rule that the traffic is distributed to the cluster and the rule that the traffic received by the cluster is forwarded to the nodes in the cluster to obtain the whole traffic forwarding rule.
For example, the rule for distributing traffic to clusters includes forwarding traffic to a first cluster when a first condition is satisfied. In a rule for forwarding traffic received by a cluster to nodes in the cluster, including when the second condition is satisfied, the traffic is forwarded to a first node in the cluster. Based on this, a traffic forwarding rule may be generated, which is forwarded to the first node of the first cluster when the traffic satisfies the first condition and the second condition.
Step 404, generating an entrance controller according to the traffic forwarding rule and the cluster information.
Specifically, after the platform determines the overall flow forwarding rule, the platform can generate the inlet controller according to the information of the clusters deployed according to the application needs.
Furthermore, the ingress controller may record the traffic forwarding rule of the application, and may record cluster information corresponding to the application, so that after the ingress controller receives the traffic of the application, the ingress controller may forward the traffic to any cluster corresponding to the application based on the recorded traffic forwarding rule.
In this embodiment, the platform can generate an ingress controller corresponding to the application, and then can perform unified forwarding processing on the traffic of the application through the ingress controller.
And step 405, according to the cluster list and the application to be published, acquiring each object configuration file corresponding to each cluster information included in the cluster list, wherein the object configuration files are files corresponding to both the clusters and the application.
In practical application, the platform may also obtain an object configuration file of the application to be published, and specifically may obtain each object configuration file corresponding to the cluster for deploying the application. For example, if an application needs to be deployed in a first cluster, a second cluster, and a third cluster, three object configuration files of the application may be obtained, where the three object configuration files respectively correspond to the first cluster, the second cluster, and the third cluster.
Wherein, an object configuration file can be preset for the cluster for deploying the application to be deployed. The object configuration file may be, for example, a replyment yaml, which is used to instruct the cluster to generate an object, and further manage applications deployed in the cluster through the object.
Specifically, when the object configuration file is acquired, a file template can be acquired first, and then the object configuration file can be obtained by adjusting the file template.
Further, a plurality of history object configuration files can be obtained, wherein the history object configuration files correspond to a plurality of clusters and applications; determining a file template in the history object configuration file according to the specified information; and modifying the file template according to the object configuration information corresponding to each preset cluster to obtain the object configuration file corresponding to each preset cluster.
When the application is actually applied, if the application to be distributed is an upgrade version of the existing application, the application has corresponding historical object configuration files when upgrading all versions of the existing application. For example, there is App1, when the App is first released, a first version is released, when the App1 of the version is released, a history object configuration file v1 needs to be set, when the App is second released, a second version is released, and when the App is released, a history object configuration file v2 needs to be set.
Thus, a plurality of history object profiles corresponding to the application to be deployed may be acquired, which may be files corresponding to the cluster in which the App is deployed. For example, a history object profile used when deployed in a first cluster, or a history object profile used when deployed in a second cluster.
Wherein, the specified information can be preset, and the specified information is used for determining the file template in the history object configuration file. For example, the user may preset a version identification for indicating which historical object configuration file is determined to be the file template.
Specifically, the object configuration information corresponding to each cluster may be preset, where the cluster refers to a cluster currently used for deploying an application. The determined file templates can be modified according to the configuration information of each object, so that a plurality of object configuration files are obtained. For example, a first object profile of a first cluster may be generated, and for example, a second object profile of a second cluster may be generated.
Further, the object configuration information may include information for performing differential configuration on different clusters, for example, a first configuration information is set for a first cluster, and a second configuration information is set for a second cluster, so that the platform may perform differential configuration on the clusters according to the configuration information.
In the embodiment, the user does not need to set object configuration files for each cluster one by one, so that the configuration efficiency of carrying out differential configuration on the clusters is improved.
In step 406, the object configuration file is sent to the cluster corresponding to the object configuration file, where the object configuration file is used to generate an object, and the object is used to manage the application deployed in the node of the cluster.
Specifically, the platform may distribute the object configuration file to the clusters, and specifically may send the object configuration file to the clusters corresponding to the object configuration file. For example, a first object profile is sent to a first cluster, a second object profile is sent to a second cluster, and a third object profile is sent to a third cluster.
Further, after the cluster receives the object configuration file, the cluster may generate an object according to the object configuration file, for example, generating a replyment according to replyment yaml.
After the objects are generated in the cluster, the application deployment process can be managed by using the objects, for example, when the App1 is deployed in a plurality of nodes of the first cluster after the object 1 is generated in the first cluster according to the first object configuration file of the App1, the flow of deploying the App1 in the cluster can be managed by the object 1.
In this way, different clusters can be configured differently for different clusters, so that different clusters can be configured differently. The configuration of a plurality of clusters for deploying the application can also be realized by configuring the object configuration file.
In an alternative embodiment, the object configuration information used to generate the object configuration file includes any one of the following information:
application release sequence, pause information after application release is completed.
The application release order refers to an order when an application is deployed in a node in a cluster, and the suspension information after the application release is completed refers to information whether suspension is required after the application is deployed in each node.
Because the object configuration information includes the application release order, pause information after the application release is completed, and the like, the object configuration file generated according to the object configuration information also includes the information, and the generated object also has corresponding information.
When the objects in the cluster manage the applications deployed in the nodes of the cluster, each application can be deployed according to the application release sequence and pause information after the application release is completed. For example, when three nodes in the first cluster are pod1, pod2 and pod3 respectively, and application app is deployed in the three nodes, management can be performed through objects, specifically, the application is deployed in pod2 first, then the application is deployed in pod1, then the application is deployed in pod3, and further, after each deployment is completed, the deployment can be paused for 30s, and then the next deployment is continued.
By the method, a richer deployment management mode can be provided, so that at least one node in the cluster can provide services to the outside, and the situation that the cluster cannot provide services to the outside when an application is deployed in the cluster is avoided.
Step 407, sending a service configuration file to each cluster recorded in the cluster list information, wherein the service configuration file is used for generating a service; the service is used to provide access addresses for the clusters.
The platform may also distribute the service configuration file to each cluster, and after the clusters receive the service configuration file, the clusters may generate service devices. The service is used to provide access addresses for clusters.
Service is a policy that can access logical groupings of nodes and can provide layer 4 load balancing capabilities. It may provide access addresses for clusters that are used for access between clusters.
After the system receives the traffic, the traffic can be distributed into the cluster, and specifically, the traffic can be sent into the cluster by using the access address of the cluster.
In this embodiment, the traffic may be forwarded to the cluster through a function provided by the service, so as to implement a traffic distribution function of the entire system.
Step 408, obtaining the application to be published, deploying the application in the nodes of each cluster recorded in the cluster list information, and determining the deployment flow according to the object of each preset cluster.
After the object and the service are configured in the cluster and the access controller independent of the cluster, the platform can acquire the application to be published, and deploy the application into the configured cluster, so as to realize the deployment of the application across the clusters.
Specifically, the cluster to which the application is deployed may be determined according to a preset cluster list corresponding to the application, and then the application to be deployed may be sent to the corresponding cluster, so that the cluster may deploy the application in an internal node.
During deployment, the clusters can perform personalized deployment on the application according to the preconfigured objects, and deployment flows of different clusters can be different.
Further, the deployed applications may include applications of a common version, and may also include applications of a test version. If the application of the normal version and the application of the test version are deployed at the same time, the applications share the portal controller, and the application of the normal version and the application of the test version deployed in the same cluster share the object, but different services may be used.
By the implementation mode, different configurations, deployment sequences and random pause points of the application in different clusters can be defined, and therefore the federal deployment requirement of the complex application is met.
Fig. 5 is a system configuration diagram of a multi-cluster deployed with applications, as shown in another exemplary embodiment of the present disclosure.
As shown in fig. 5, there are a plurality of clusters 51 in the system architecture, each cluster includes a plurality of nodes, and applications are deployed in the nodes, for example, app1 may be deployed and App2 may also be deployed.
The method provided according to the present disclosure may generate the ingress controller 52 according to the deployed application, for example, may generate the ingress controller 52 for forwarding the traffic of App1, and may also generate the ingress controller 53 for forwarding the traffic of App2.
Services and objects may also be configured in the cluster 51, respectively, for providing access addresses of the cluster, and objects for managing applications deployed in the cluster 51, such as for managing the services and objects of App1, and for managing the services and objects of App2.
Fig. 6 is a flow chart of a flow forwarding method in a multi-cluster scenario according to an exemplary embodiment of the present disclosure.
As shown in fig. 6, the traffic forwarding method in the multi-cluster scenario provided by the present disclosure includes:
In step 601, a flow is received and parsed.
A system provided with a plurality of clusters may receive traffic for accessing an application service, which may be a request for example, which the system may parse. For example, the intelligent DNS may be used to resolve a domain name of the flow, and send the resolved result to a preset ingress controller.
The inlet controller may be generated according to the embodiment shown in fig. 2 or fig. 4.
In step 602, if the traffic includes the test parameters, a first destination cluster provided with the test node and the test node deployed with the test version application are determined in the multiple clusters according to the preset ingress controller.
Step 603, forwarding the traffic to the test node of the first destination cluster.
In one embodiment, if the parsing result characterizes the flow including the test parameters, it indicates that the flow should be processed by the test version application.
Thus, the ingress controller may determine a destination cluster in which the test node is provided among the plurality of clusters, and determine the test node in the destination cluster. The test node refers to a test node deployed with a test version application.
Specifically, the ingress controller may determine an access address of the first destination cluster and an access address of the test node, and then the ingress controller may send traffic to the test node according to the two addresses.
Step 604, if the traffic does not include the test parameter, determining a destination cluster corresponding to the traffic and a destination node in the destination cluster according to a preset inlet controller; the destination node is deployed with a normal version application.
Step 605, the traffic is sent to the destination node.
