Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, device, electronic device and storage medium for adding an agent service. Background Art

[0002] In a Kubernetes cluster, domain name resolution services are typically provided by components such as CoreDNS. This component not only provides domain name resolution services for Pods and Services within the cluster, but also forwards domain name requests from within the cluster to external domain name resolution servers (upstream DNS servers) outside the cluster, thereby achieving domain name resolution. However, using only CoreDNS can lead to the following two problems: 1) If the Kubernetes control plane node where CoreDNS is located fails, domain name resolution services will be unavailable. In a Kubernetes cluster, service names are a strong dependency for calls between services. This means that a CoreDNS exception can cause the entire Kubernetes cluster to be unavailable.

[0003] To improve the availability of the Kubernetes cluster's domain name resolution service and avoid the DNS resolution UnknownHost problem, you can add two types of plug-ins, LocalDNS and CoreDNS, to the cluster to solve the problem.

[0004] Existing technologies support configuring LocalDNS and CoreDNS together during initial configuration. Alternatively, adding LocalDNS to an existing CoreDNS configuration and then restarting existing Kubernetes pods to refresh and take effect in the / etc / resolve.conf file requires restarting the application pods, which undoubtedly affects the continuity of existing pods and is unacceptable in production environments. Therefore, how to add localDNS resolution without affecting the business continuity of existing applications in the Kubernetes cluster is an urgent problem. Summary of the Invention

[0047] Example 1

[0048] Figure 1 A flowchart of a proxy service adding method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of adding a proxy service to a service in a cluster. The method can be executed by a proxy service adding device. The proxy service adding device can be implemented in the form of hardware and / or software. The proxy service adding device can be configured in a cloud server. Figure 1As shown, the method includes:

[0049] S110: Acquire the proxy service to be added and determine the service status of the proxy service.

[0050] In the embodiments of the present invention, the cluster service platform can be understood as a Kubernetes cluster. This cluster includes multiple nodes. Specifically, only one of these nodes serves as the cluster master, executing cluster control commands. The other nodes serve as slave nodes. Upon receiving a service request from a slave node, they forward the request to the master node for processing.

[0051] In this embodiment, the local service deployed in the master node can be understood as the default CoreDNS in Kubernetes. Specifically, CoreDNS can provide domain name resolution services for the Kubernetes cluster. In actual application, CoreDNS not only provides domain name resolution services for Pods and Services within the cluster, but also forwards domain name requests within the cluster to domain name resolution servers outside the cluster (upstream dns servers), thereby achieving domain name resolution. However, using only CoreDNS will face the problem of the entire Kubernetes cluster being unable to provide services when CoreDNS is abnormal. Therefore, the technical solution of this embodiment adds a proxy service to each node of the cluster. Among them, the proxy service can be understood as LocalDNS deployed in each Node of the Kubernetes cluster to improve the DNS performance of the cluster.

[0052] In this embodiment, when a proxy service to be added is obtained, the service status of the proxy service needs to be determined in advance to ensure that it can provide corresponding services in the cluster service platform after being added. Optionally, the method for determining the service status of the proxy service in this embodiment may include: determining the local service deployed by the master node and generating service resources corresponding to the local service; and performing a health check on the proxy service to be added based on the service resources to determine the service status of the proxy service.

[0053] Specifically, the CoreDNS deployed in the Master node within the Kubernetes cluster is identified, and a new Service is created for the CoreDNS. A new Service IP is assigned to the Service. This new Service IP is inconsistent with the Service Cluster IP of other existing Services in the CoreDNS, so as to distinguish existing Services in CoerDNS from new Services. Furthermore, the corresponding Service is determined based on the new Service IP, and a health check is performed on the obtained LocalDNS based on the Service to determine the service status of the LocalDNS.

[0054] S120: When the proxy service is in a healthy state, add the proxy service to the sub-node.

[0055] In this embodiment of the present invention, the service status of the proxy service includes normal status and abnormal status. If the LocalDNS is determined to be in a healthy state, it can be directly added to the Kubernetes cluster. Conversely, if the LocalDNS is in an abnormal state, it needs to be restarted first. After it is in a healthy state, it can be added to the Kubernetes cluster, thereby ensuring that the LocalDNS added to the Kubernetes cluster can directly provide the corresponding services.

[0056] Optionally, when the proxy service is determined to be in a healthy state, it is added to a sub-node of the cluster service platform. Optionally, the method of adding the proxy service to the sub-node may include: obtaining a preset daemon process set, and adding the proxy service to the sub-node based on the daemon process set.

[0057] The daemon set can be understood as a preset DaemonSet. Specifically, LocalDNS is deployed in the Kubernetes cluster using DaemonSet.

[0058] It should be noted that, based on the number of each sub-node, multiple proxy services to be added can be obtained, and when the health status of each proxy service is determined, each proxy service can be added to each sub-node to increase the service performance of the cluster service platform.

[0059] S130: Add a preset interface in the sub-node, and bind the proxy service of the sub-node to the local service based on the preset interface.

[0060] In an embodiment of the present invention, in order for the proxy service in each subnode to process service requests within the node, each proxy service must be pre-bound to a local service in the master node. Optionally, the method for binding services in this embodiment may include associating a proxy service address of the proxy service in the subnode with a local service address of the local service based on a preset interface to achieve binding of the proxy service and the local service.

[0061] Specifically, taking the binding of the proxy service of any sub-node in this embodiment to the local service as an example, the preset interface in the current sub-node, such as interface 53, is started. Based on the started interface 53, the service IP of the localDNS in the current decomposition point is set to the same IP as the old CoreDNS Service, so that the domain name resolution request received at the current sub-node is changed from the original CoreDNS processing to LocalDNS processing, thereby realizing the addition of localDNS resolution without restarting, so that this change is transparent to existing applications in the production environment.

[0062] Optionally, in this embodiment, before binding the proxy service of the current subnode with the local service, it is necessary to pre-add a preset interface to the current subnode. Optionally, the method for adding the preset interface in this embodiment may include: obtaining a virtual network card added to the subnode, and adding the preset interface to the subnode based on the virtual network card.

[0063] Specifically, for the current node, execute the ip link add command in the node to add a virtual network card. After the virtual network card is added, create a network interface based on the added virtual network card. Optionally, name the created interface "interface 53" to facilitate service binding based on the interface.

[0064] Based on the above-mentioned implementation mode, the technical solution of the present invention also includes receiving a domain name resolution service request, and determining whether the sub-node caches the resolution result corresponding to the domain name resolution service request based on the proxy service; if the sub-node does not cache, the domain name resolution service request is sent to the local service based on the proxy service, and it is determined whether the cluster service platform caches the resolution result corresponding to the domain name resolution service request; if the cluster service platform does not cache, the domain name resolution service request is sent to an upstream service outside the cluster service platform based on the proxy service to determine the resolution result corresponding to the domain name resolution service request.

[0065] Among them, the domain name resolution service can be based on the task request received by any sub-node. In actual applications, when a sub-node receives a domain name resolution request, it will first perform a resolution judgment through the LocalDNS of the current sub-node. If there is a cache in the current sub-node, the domain name resolution result will be returned immediately. If the current sub-node does not find the cache, it will be forwarded according to the domain name ownership. If the domain name belongs to the Kubernetes cluster, the domain name request will be forwarded to CoreDNS, and CoreDNS will perform domain name resolution; if the domain name belongs to outside the Kubernetes cluster, CoreDNS will be skipped and the domain name request will be forwarded directly to the upstream DNS Server outside Kubernetes, thereby realizing the domain name resolution method of collaboration between LocalDNS and CoreDNS.

[0066] Optionally, in the technical solution implemented in this embodiment, when forwarding the domain name resolution request, the proxy service sends the domain name resolution service request to the local service through the TCP transmission protocol, and the proxy service sends the domain name resolution service request to the upstream service through the UDP transmission protocol.

[0067] Specifically, in LocalDNS, you can use ConfigMaps to set up cache and upstream services (forwarding) for domain names within the Kubernetes cluster and for domain names outside the cluster. Specifically, for domain name requests within the Kubernetes cluster, you can set the forwarding direction to the new CoreDNS ServiceIP and enforce TCP connections between LocalDNS and CoreDNS. This effectively avoids packet loss and significantly improves the availability of the Kubernetes cluster's domain name service. For domain name requests outside the Kubernetes cluster, you can set the forwarding direction to an external DNS server.

[0068] The technical solution of the embodiment of the present invention obtains the proxy service to be added and determines the service status of the proxy service; when the proxy service is in a healthy state, the proxy service is added to the sub-node; a preset interface is added in the sub-node, and the proxy service of the sub-node is bound to the local service based on the preset interface, so that the proxy service can process the service requests received by the sub-node. The above technical solution binds the added proxy service to the local service based on the service address, thereby processing the service request of the local service based on the proxy service without restarting the application, solving the problem of the existing technology that adding a proxy service affects the continuity of the cluster, and realizing transparently increasing the proxy continuity on the basis of the local service to improve the service performance of the cluster.
