In this embodiment, a central station, an Envoy agent, and a plurality of service servers are deployed on a k8s container cluster, where the system structure of the system may be shown in fig. 3, where the service servers are deployed on Pod (container nodes) of the k8s container cluster, and different service servers may be deployed on different Pod, or may be deployed on the same Pod, that is, one service server may be deployed on one Pod, or may be deployed on a plurality of service servers. In practical applications, the business server may be a server for providing various business services, for example, an ES (search engine) server.
Envoy agents act as agents for multiple business servers, which can be deployed over k8s container clusters through YAML. As shown in fig. 3, a system may include multiple Envoy agents, e.g., one Envoy agent deployed per Region (Region), each Envoy agent responsible for the agents of multiple service servers within the Region.
The middle station can be used as a management end of the whole system, the Envoy agent and the service server are registered to the middle station after being started, the service server can be registered to the middle station through a starting script, and in the registration process, the middle station can be informed of the area (Region) of the container node where the service server is located so as to be used when the middle station subsequently creates the route information, and meanwhile, the address and the port of the service server are registered to the middle station. The address of the Envoy agent may be registered with the intermediate station via a configuration file for subsequent intermediate stations to send messages to the Envoy agent.
Based on the system structure shown in fig. 3 in the embodiment of the present application, the embodiment of the present application provides a method for creating routing information of a k8s container cluster, as shown in fig. 4, including:
and step 41, the middle station adopts xds protocol to send configuration information acquisition requests to a plurality of service servers.
In this step, the intermediate station sends a configuration information acquisition request for reading the configuration information of the service server, for example, the configuration information may be the configuration information stored in the configmap in advance.
The intermediate station may initiate xds a service, send a message using the xds protocol via xds a service, for example, in this step, may direct the address and port provided when the service server registers to xds a service, and send a configuration information acquisition request to the service server using the address and port of each service server by xds a service using the xds protocol.
Step 42, the middle station receives configuration information returned by the plurality of service servers by adopting xds protocol.
The configuration information returned by the plurality of service servers may include: protocols supported by the service server, resource restriction information, namespaces (namespaces), and the like.
In this embodiment of the present application, when a service server registers in a home node, the home node may also belong to the configuration information of the service server, where a container node where the service server is located belongs to (Region).
And 43, the middle station creates routing information of the plurality of service servers based on configuration information of the plurality of service servers, wherein the configuration information comprises an area of a container node where the service server is located.
Step 44, the intermediate station sends the intermediate station communication information to the Envoy agent according to the address of the Envoy agent.
In this step, the intermediate station body may send the intermediate station communication information to the upstream module of the Envoy proxy.
Step 45, after receiving the intermediate station communication information of the intermediate station, the Envoy agent transmits a xds address request to the intermediate station based on the intermediate station communication information.
Step 46, after receiving the xds address request, the intermediate station returns xds address of the intermediate station to the Envoy agent.
Step 47, the Envoy agent receives the xds address of the intermediate station, and then transmits a discovery request (discovery request) to the intermediate station according to the xds address by using xds protocol.
There is no strict order between steps 41-43 and steps 44-47.
And 48, after receiving the discovery request, the intermediate station returns the routing information of the service servers to the Envoy proxy by adopting a xds protocol.
The routing information of the plurality of service servers comprises information for configuration, such as resource information, addresses and the like of the service servers.
In this embodiment of the present application, after receiving the routing information of the plurality of service servers, the Envoy proxy may select, from the plurality of service servers, a service server for processing the service request according to the routing information and a pre-configured routing rule, after receiving a service request sent by the client (for example, the Envoy listenner module listens to the service request from the client); and forwarding the service request to the selected service server according to the routing information, thereby realizing stable, rapid and effective routing of the service request to the proper service server.
In this embodiment of the present application, the Envoy proxy is used as a proxy of the service server, where the routing rule may be configured in a configuration file, an API, etc., and the routing rule may be dynamically generated, and the routing rule may include a plurality of matching conditions and actions, such as a request header, a request parameter, a path, a weight, a load balancing policy, and so on.
Therefore, when the service server deployed on the k8s container cluster changes, for example, there is a newly added service server, or the registered service server logs off, by adopting the method provided by the embodiment of the application, the update of the routing information can be quickly realized, and the quick dynamic configuration update of the routing rule can also be realized.
In the embodiment of the application, in order to improve the stability and performance of the k8s container cluster, the same number of worker threads can be created according to the number of CPU cores of the physical machine where the Envoy agent is located, and all worker threads are simultaneously configured with a monitor (listenner) to monitor, so that the k8s container cluster consumes less resources and is more stable.
During operation of the Envoy Agent, the control plane components Pilot Agent and Sidecar-injection may be used to manage the operation state of the Envoy Agent. The Pilot Agent is responsible for managing the operation state of the Envoy Agent, and if the operation state of the Envoy Agent has a problem, the Envoy Agent is restarted; if the restart is still unable to solve the problem, an attempt may be made to schedule the Envoy agent to other environments.
