The Kubernetes cluster manager is used for creating services in the Kubernetes cluster and configuring configuration information of the services.
In the following, the load balancing method provided by the embodiment of the present invention is introduced from the perspective of the Nginx manager, and the load balancing method described below may be referred to in correspondence with the signaling flow content described above.
Fig. 4 is a flowchart of a load balancing method according to an embodiment of the present invention, where the method is applicable to the Nginx manager, and referring to fig. 4, the method may include:
step S100, receiving configuration information of the service from a Kubernetes cluster;
the Nginx manager is connected with APIs (application programming interfaces) of multiple kubernets clusters, and after monitoring that creation of a new service exists in a kubernets cluster, the APIs of the kubernets cluster acquire configuration information of the newly created service and then send the acquired configuration information of the newly created service to the Nginx manager.
On the other hand, the Nginx manager in the embodiment of the present invention also obtains the creation of a new service in the kubernets cluster through the watch mechanism.
Similarly, after the API of the kubernets cluster monitors that the configuration information of the service in the kubernets cluster is updated, the updated configuration information of the service is sent to the Nginx manager.
A service corresponds to a kind of configuration information, the contents of the configuration information of different services are different, the configuration information of the service at least includes: container address, service domain name, service port, and various annotation information of the service, etc., which are not specifically limited in the embodiments of the present invention.
The service domain name is used to uniquely identify a service, and optionally, the service domain name may be in the form of: the service name-namespace-unified suffix mainly bears the position information of the service in the kubernets cluster, and the embodiment of the invention is not specifically limited to the specific content of the unified suffix. The domain name of the service in the embodiment of the present invention is mainly resolved to the Nginx manager through a DNS (domain name system, domain name system (service) protocol).
A service corresponds to a unique service port, and the same service has the same service port in different kubernets.
Step S110, establishing a configuration file for the target service in the Kubernetes cluster according to the configuration information of the service;
after receiving the configuration information of all services, the Nginx manager determines a target service needing to create a configuration file in the Nginx manager according to the configuration information of the services; and creating a configuration file for the target service according to the configuration information of the target service.
Specifically, the Nginx manager judges whether the configuration information of any service contains a preset identifier, and if so, creates a configuration file for a target service containing the preset identifier; and for the target service which does not contain the preset identification, a configuration file is not created. Specifically, it is determined whether the annotation information in the configuration information of any service includes the annotation of domain, and if so, a configuration file is created for the target service including the annotation of domain.
The process of creating a configuration file for the target service in the Kubernetes cluster is as follows: integrating the relevant configuration information corresponding to the target service into a configuration file form, specifically, one service corresponds to only one configuration file, and the configuration file at least comprises the following information: a container address, a domain name of the service, a type of the service (e.g., whether the service is a service directly registering the container, etc.), a port nodoport of the service, and the like.
Specifically, the Nginx manager in the embodiment of the present invention further receives update configuration information of the target service from the kubernets cluster; and updating the configuration file corresponding to the target service by using the updated configuration information of the target service.
In the Kubernetes cluster, regardless of whether the configuration information (for example, Pod address) of the container corresponding to the target service is updated or the configuration information of the target service is updated, the updated information is sent to the Nginx manager, and the Nginx manager updates the configuration file corresponding to the target service by using the updated information.
The updating process may specifically be adding new configuration information to the configuration file, and the old configuration information may be deleted or retained.
When a service in the kubernets cluster is deleted, the configuration file corresponding to the service stored in the corresponding Nginx manager is also deleted.
Optionally, in the embodiment of the present invention, service creation is mainly performed in a kubernets cluster through a kubernets cluster manager (for example, ipaas), where the kubernets cluster manager is configured to create a service in the kubernets cluster and configure configuration information of the service, and when the kubernets cluster manager performs service creation, the kubernets cluster manager calls interfaces of multiple kubernets clusters, and the service creation service, attribute information Deployment corresponding to the service, and configuration file configuration map of the service respectively include at least: the domain name of the service, the mirror version of the service, the number of copies of the service, the environment variable of the service, and the like.
Step S120, determining an access data stream corresponding to the target service according to a preset load balancing strategy;
the load balancing policy is, for example: load averaging strategy, weight strategy, minimum connection number strategy, polling strategy, IPhash strategy and the like.
The load averaging strategy refers to the load averaging on the target service in the Kubernetes cluster; the weight strategy is mainly to calculate the weight according to the response time of the target service, select the target service according to the obtained weight, and the probability that the target service with shorter corresponding time is selected is higher; the minimum connection number strategy is used for carrying out load balancing according to the current connection condition of the target service, and when the access data flow comes, the target service with the minimum current connection number is selected to process the access data flow; the polling strategy is to distribute the access data flow to target service in Kubernetes cluster in turn; the iphhash policy is to direct the access data streams with the same source IP address to the same target service.
Optionally, the access data stream corresponding to the target service in the embodiment of the present invention includes:
access data flow between kubernets clusters in a kubernets system and/or access data flow outside the kubernets system.
That is, the data flow to be allocated for which the nginnx manager is directed may be an access data flow between kubernets clusters, and may also be an access data flow outside the kubernets system. Therefore, the embodiment of the present invention may perform balanced distribution not only on access data streams between the kubernets cluster and the kubernets cluster, but also on access data streams from outside the kubernets system, and the embodiment of the present invention is not particularly limited.
Step S130, sending the configuration file corresponding to the target service and the access data stream to a Nginx server, and enabling the Nginx server to forward the access data stream to the target service in the Kubernetes cluster according to the configuration file.
The Nginx server may obtain relevant configuration information of the target service from the configuration file, for example, the port of the service, the IP address of the container, or the like, which is located to the storage location of the target service in the kubernets cluster, and then forward the access data stream to the target service in the kubernets cluster.
After sending the configuration file corresponding to the target service and the access data stream to the Nginx server, the Nginx manager also sends loading indication information of 'Nginx-srreload' to the Nginx server, so that the target Nginx server loads the configuration information according to the 'Nginx-srreload'.
The Nginx-srreload can instruct the Nginx server to load the configuration file and access the data stream without interrupting the service running per se, thereby avoiding the influence on the running state of the Nginx server.
It should be noted that the target service may specifically refer to a service located in the same kubernets cluster, or may also refer to a service located in different kubernets clusters, that is, in the embodiment of the present invention, load balancing adjustment may be performed on a service in the same kubernets cluster, or may also be performed on a service located in different kubernets clusters.
The method in the embodiment of the invention comprises the following steps: the Kubernetes cluster sends configuration information of the service to an Nginx manager, and the Nginx manager creates a configuration file for a target service in the Kubernetes cluster according to the configuration information of the service; determining an access data stream corresponding to the target service according to a preset load balancing strategy; sending a configuration file corresponding to the target service and an access data stream to an Nginx server; and the Nginx server forwards the access data stream to a target service in the Kubernetes cluster according to the configuration file. The Nginx manager can determine the access data flow corresponding to the target service according to a preset load balancing strategy, and realize uniform balanced distribution of the access data flow corresponding to the target service in the Kubernets cluster, so that the load balancing of the service in the Kubernets cluster is realized, uniform management of the service in the Kubernets cluster is further realized, and uniform distribution of the access data flow is also realized.
According to the embodiment of the invention, the services in the Kubernetes cluster are uniformly registered in the Nginx manager, and the registration of the services can be completed without a registration center of a third party.
By the method, the load balance of the services in the Kubernets clusters can be realized, the access data streams can be distributed to the clusters, after a certain cluster fails, the access data streams can be distributed to other clusters which do not fail, and the high availability of the services in the Kubernets clusters is guaranteed.
Optionally, the embodiment of the present invention further provides a terminal visualization interface connected to the Nginx manager, and a user may view the operation status of each service in the kubernets cluster and the allocation condition of the access data stream through the terminal visualization interface, and may visually present differences between each service configuration and the Nginx configuration in the kubernets cluster through the visualization interface, thereby improving a user experience level.
The Nginx manager in the embodiment of the present invention may also monitor an external request amount of the Nginx, including a normal access request and an abnormal request traffic with HTTP return codes of 4xx and 5 xx.
In order to further improve the load balancing effect, an embodiment of the present invention provides another load balancing method, and fig. 5 is a flowchart of the load balancing method provided in the embodiment of the present invention, where the method is applicable to the Nginx manager, and referring to fig. 5, the method may include:
step S200, receiving configuration information of the service from the Kubernets cluster;
step S210, according to the configuration information of the service, a configuration file is established for the target service in the Kubernetes cluster;
step S220, determining an access data stream corresponding to the target service according to a preset load balancing strategy;
step S230, sending a configuration file corresponding to the target service and an access data stream to a Nginx server, so that the Nginx server forwards the access data stream to the target service in a Kubernetes cluster according to the configuration file;
steps S200 to S230 in the embodiment of the present invention are the same as steps S100 to S130 in the above steps, and specific contents may be referred to correspondingly.
In order to realize monitoring of the Nginx server, the Nginx manager in the embodiment of the invention also sends a heartbeat check instruction to the Nginx server, monitors the operation condition of the Nginx server according to the response information of the Nginx server, and sends out an abnormal alarm prompt in time under the condition that the operation fault of the Nginx server is monitored, so as to ensure the normal operation of the Nginx cluster.
Meanwhile, if the Nginx server detects that the access data stream sent to the Kubernetes cluster fails to be sent, the Nginx server also sends alarm information to the Nginx manager in time to prompt that the access data stream fails to be sent, and requests to resend or perform other processing.
Step S240, sending traffic monitoring instruction information to a nginnx server, so that the nginnx server monitors traffic of an access data stream sent to the Kubernetes cluster.
The method includes that a Nginx server monitors the flow of access data flow sent to a Kubernets cluster by sending flow monitoring indication information to the Nginx server, and specifically, the flow to be monitored includes both the access flow between the Kubernets cluster and the access flow outside a Kubernets system. When the Nginx server monitors that the flow of the access data stream corresponding to a certain Kubernetes cluster reaches the access flow threshold corresponding to the Kubernetes cluster, sending indication information to the Nginx manager to indicate the Nginx manager to adjust a load balancing policy for the Kubernetes cluster, for example, the Nginx manager may time limit partial access data streams according to the indication information, for example, limit the issuing of low-priority service access data streams, and only allow the issuing of high-priority service access data streams.
In the embodiment of the invention, the Nginx server monitors the flow of the access data stream sent to the Kubernetes cluster and sends the monitoring result to the Nginx manager, so that the Nginx manager can timely adjust the load balancing strategy of the Kubernetes cluster, namely, the accuracy of the load balancing strategy adjustment is improved in a feedback adjustment mode.
