In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
First, to facilitate understanding, a brief description will be given of terms that may be referred to in this application. Wherein:
kubernetes: a containerization orchestration system.
Service: definition of a service in kubernets.
Pod: under the minimum definition of an instance under one Service in kubernets, one Service may have multiple Pod.
Referring to fig. 1, a flowchart of a method for detecting a traffic status according to an embodiment of the present application is shown, where as shown in fig. 1, the method includes:
step 101, obtaining a route configuration file;
optionally, this step may include:
firstly, analyzing an access website to obtain a host identity host in the access website;
when a user accesses a URL (uniform resource locator), the server parses the URL to obtain a host identifier host.
Secondly, the route configuration file at the entrance of the IstioIngressgateway is obtained according to the host identity host.
After the host is obtained through analysis, the routing configuration file at the entrance of the IstioIngressgateway can be obtained according to the host.
102, analyzing a calling link according to the routing configuration file and generating a detection execution plan;
the method comprises the following steps:
firstly, acquiring an access path and a service name of an accessed target service;
similar to the above-mentioned acquisition method of the host, after the server obtains the URL, the server may obtain the access path and the traffic label by analyzing the URL, and after the traffic label is obtained, the server may read and obtain the version information of the target service currently requested to be accessed according to the traffic label.
Secondly, determining the calling link according to the access path, the service name of the target service and the routing configuration file, and generating a detection execution plan.
Optionally, this step may include:
(1) determining routing service and version information of a next hop in the routing configuration file according to the access path and the service version of the target service;
(2) and analyzing according to the determined routing service of the next hop to obtain a complete service path and a service node in the service path, and obtaining the call link.
Optionally, if the determined next-hop routing service is an API gateway, searching a next-hop routing service of a gateway route in a routing table of the API gateway, retrieving a corresponding routing configuration table according to a service name of the next-hop routing service, and further finding the target service to be accessed according to the service version of the target service and the access path;
and searching a VirtualService routing configuration table corresponding to the service according to the service name, and finding the service version of the target service needing to be accessed according to the path and the trafficlabel.
And if the determined routing service of the next hop is the intermediate node, searching a corresponding routing configuration table according to the service name of the intermediate node, and further finding the target service to be accessed according to the service version of the target service and the access path.
That is, when the next-hop routing service is an intermediate node, the corresponding VirtualService routing configuration table can be retrieved according to the service plane name, and then the service version of the target service to be accessed is found.
After the service version of the target service to be accessed is found, a complete service path and each service node in the path can be obtained, and then a detection execution plan can be generated. Wherein, detecting the execution plan may include sequentially probing at least one of an ingress probe, a gateway probe, and a service probe, and the probing event includes at least one of a service access probe, a service status probe, a Pod access probe, and a configuration status probe. Wherein Pod is the minimum/simplest basic unit created or deployed for kubernets, and one Pod represents one running process on the cluster.
When the detection execution plan is generated, a preset execution template can be called, and the detection items in each step are defined in the execution template, so that the final detection execution plan is obtained. In practical implementation, an executor may be constructed for each step according to the execution template, for example, an ingress probe, a gateway probe, and a service probe are constructed. Of course, the order in the execution templates may also be adjusted or other functions may be extended as desired.
Assuming that the URL to be accessed is as the name, a possible route analysis process, after the URL is obtained, three steps of Istio route analysis, gateway route analysis and service route analysis are carried out. Wherein the Istio route analysis comprises: and analyzing the URL to obtain host, path and trafficlabel, obtaining a routing configuration file according to the host, searching in the routing configuration file according to the path and trafficlabel to obtain the next hop service of the gateway routing, and then performing gateway routing analysis. When the found next-hop service is the API gateway, the routing table of the API gateway can be found according to the host, the next-hop service of the gateway route is found in the routing table according to the path and the traffic label, and then the service route analysis is carried out. In the service routing analysis, a VirtualService routing configuration table corresponding to the service can be detected according to the service name in the host, and the service version needing to be accessed can be found in the routing configuration table according to the path and the traffic, for example, the found service is traffic-client, and the version is swzhou.
103, acquiring detection results of all detection items according to the detection execution plan;
after the detection execution plan is obtained, the detection result of each detection item can be obtained according to the detection execution plan. Optionally, when a plurality of probes are included, in order to increase the detection speed, each probe may be executed independently, that is, the ingress probe, the gateway probe, and the service probe may be executed in an independent co-routine, so that the overall detection speed is determined by the execution speed of the slowest step.
Referring to fig. 2, a possible schematic diagram of the system including an ingress probe, a gateway probe and a service probe together, and the probing events include a service access probe, a service status probe, a Pod access probe and a configuration status probe simultaneously is shown.
It should be added that the above is only exemplified by detecting the above matters, and in actual implementation, example log detection can be introduced according to requirements, so that a request access log can be obtained during traffic state detection, and the detection problem is more intuitively and conveniently exposed.
And 104, determining the flow state according to the detection result of each detection item in the detection execution plan.
After the test execution plan is executed, the flow state may be determined based on the probe results of each probe event in the test execution plan. In the step, the execution results of the detection items in each detector can be collected in a unified mode, and the subsequent result presenting and reading efficiency is improved.
One possible flow state detection method provided in an embodiment of the present application may include a parameter analysis stage, an execution stage, and an output stage. In the analysis stage, after the URL is obtained, the URL is analyzed to obtain a host, a path and a trafficlabel, and then the analysis stage is started. In the analysis stage, a complete calling link can be obtained through the Istio route analysis and the API gateway route analysis, a corresponding execution plan is generated, and then the execution stage is started. Wherein the execution plan comprises an ingress probe plan, a gateway probe plan and a service probe plan. In the execution stage, the probing may be performed sequentially by an ingress probe, a gateway probe, and a service probe, wherein a probe template may be loaded when generating a probe plan for each probe, and probe items in the probe template include at least one of service access probe, service state probe, Pod access probe, and configuration state probe.
