Fig. 2 is a flow chart illustrating a method of controlling a cross-cluster network in accordance with an exemplary embodiment. The method as shown in FIG. 2 may be applied to a cloud environment comprising a plurality of clusters, such as may be applied to the cloud environment shown in FIG. 1; the method as shown in fig. 2 may be performed by a network plug-in disposed on one (management) cluster, for example, may be implemented by the first network controller 602 in fig. 6.

Referring to fig. 2, a method 20 provided by an embodiment of the present disclosure may include the following steps.

In step S204, when the state of the first workload is obtained as the first state, a first application load balancer exposed to the outside is created for the first workload.

In some embodiments, the first status may be a ready status, and whether the first workload is ready may be determined by monitoring a resource incremental change through a controller (controller) mechanism of kubernets, for example, a resource change event of the first workload may be detected at a preset frequency, and if the resource change event of the first workload is not detected within a preset length time period, the status of the first workload is obtained as the first status.

In some embodiments, the exposed first Application Load Balancer may be an externally accessible Application Load Balancer (ALB).

Reference may be made to fig. 4 for a specific embodiment.

Each cluster in the related art is in an independent VPC, networks between VPCs are isolated, an ALB (or domain control) in a cluster cannot schedule nodes across clusters, so that nodes between clusters are isolated, a same instance cannot be created across clusters, manual intervention migration and switching are required when network scheduling across clusters is involved, and scalability of clusters and network resources is limited.

According to the cross-cluster network control method provided by the embodiment of the disclosure, after the target application instance is determined to be the cross-cluster application instance, the state of the first workload for bearing the target application instance and including the plurality of resource units distributed in the plurality of clusters is obtained at the preset frequency, when the state of the first workload is obtained to be the first state, the first application load balancer exposed to the outside is created for the first workload, then the first application load balancer is respectively mounted with the plurality of first internet protocol addresses corresponding to the plurality of resource units exposed to the outside in the plurality of resource units of the first workload, and then the plurality of resource units exposed to the outside are subjected to network configuration according to the plurality of first internet protocol addresses, so that the first application load balancer distributes network data processed by the target application instance according to the plurality of first internet protocol addresses, therefore, cross-cluster network node scheduling can be realized, and automatic cross-cluster instance management is realized.

Fig. 3 is a schematic diagram illustrating a processing procedure of step S202 shown in fig. 2 in an embodiment. As shown in fig. 3, in the embodiment of the present disclosure, the step S202 may further include the following steps.

Step S302, obtaining the configuration information of the target application instance, wherein the configuration information comprises the label information of the target application instance.

Step S304, judging whether the label information of the target application example comprises a cross-cluster application example label.

Step S306, if the tag information of the target application instance includes a cross-cluster application instance tag, acquiring the state of the first workload at a preset frequency.

In some embodiments, the network plugin may be managed by an operator (operator) of kubernets in a declarative Application Interface (API) style customization of kubernets, so as to implement monitoring of the workload status, and the specific implementation may refer to step S202.

In step S504, second routing information is configured for the second resource unit, the second routing information includes the classless inter-domain routing information of the first subnet and the first internet protocol address, and the second routing information is used to indicate that the second subnet accesses the first resource unit.

In some embodiments, the pod that has been exposed to the outside can be accessed through the second subnet, for example, the pod can be a first resource unit in the first subnet, and the second routing information is added to the second resource unit to open the network between the second resource unit and the first resource unit in different subnets.

In some embodiments, this may be accomplished by a network plug-in (such as the second network controller 606 shown in FIG. 6) disposed on the cluster in the subnet.

In step S506, the first application load balancer is mounted with the second internet protocol address.

In the related art, network access between two VPCs is realized by using a certain IP address in a network card binding subnet (subnet) of one of the VPCs, and inserting the network card into a node (node) of the other VPC after the network card is granted, so that after the IP address of the subnet is exhausted, the existing instance cannot be expanded.

Fig. 7 is a schematic diagram of another implementation of the cross-cluster network control device in an application scenario according to fig. 6. Fig. 7 is a user-side virtual private cloud 70 environment corresponding to fig. 6, in which the first subnet 70002 and the second subnet 70004 correspond to the first subnet 60002 and the second subnet 60004 in fig. 6, respectively, and step S64 and step S65 are involved, respectively, and may be used to transfer a first capacity expansion request from the user side.

According to the method provided by the embodiment of the disclosure, a network plug-in is arranged on a first cluster according to the configuration on a target application example, if a label of cross-cluster application is found, the ready state of corresponding workload in a multi-cluster management module is monitored, once the label is ready, an externally exposed ALB is created for the workload, the ALB can mount the IP addresses of the credit granting network cards corresponding to the exposed pots on each cluster one by one, then whether the ALB needs to bind a public network or not is judged according to the configuration, and a domain name is configured; the first cluster and the second cluster are respectively provided with network access plug-ins with single cluster dimensionality, and an asynchronous dual-operator mechanism is adopted to be responsible for automatic maintenance of externally exposed network resources (domain names/load balancing/network cards/public network IP/security groups) of the clusters, so that the problems of cross-cluster network node scheduling and capacity expansion of a public cloud service provider and multi-subnet communication and access of a user use side are solved. The method not only supports the capacity expansion and the external exposure of the service side cross-cluster creation instance, but also supports the capacity expansion of the corresponding user side network resource, and can increase the continuous capacity expansion of the subnet after the IP address in the same subnet as the VPC is exhausted, thereby greatly improving the expandability of the system.

Fig. 8 is a schematic diagram of an implementation of the cross-cluster network control device in an application scenario according to the embodiments shown in fig. 2 to 7. The plurality of clusters in fig. 8 may be one main Cluster (Host Cluster)802 and a plurality of K8s sub-clusters, such as K8s Cluster 1, K8s Cluster 2 … … K8s Cluster n shown in fig. 8. The master cluster 802 may be used as a management node and other types of clusters registered as sub-clusters on the master cluster 802. The K8s cluster 1, the K8s cluster 2 … … K8s cluster n constitute service sides (servicepins) 804, each cluster is 2-3 Availability Zones (AZ) deployments (Availability zone a, Availability zone B, and Availability zone C as shown in fig. 8), and nodes in the same cluster may correspond to different physical AZ. Corresponding to the service side, the user side (userPin) VPC 806 also includes 2 subnet of the user, such as subnet 1 and subnet 2 shown in fig. 8, where K8s cluster 1, K8s cluster 2 … … K8s cluster n are under the same account and same area (region) under servicePin (e.g. area 1 shown in fig. 8).

The multi-cluster management software 8022 may have different options, for example, it may process workload information such as deployment information, cluster information, etc. through the controller 80242 disposed at the node 8024, the controller 80262 disposed at the node 8026, and resources such as a mediation Domain (Domain), a public network IP address (implemented by svc (service)), an ALB, etc. If the number of copies (replicas) of a pod in Deployment (Deployment)1 is 3, resource unit 1, resource unit 2, and resource unit 3 shown in fig. 8 are added with copy resource unit 4 of 4 during capacity expansion.

The K8s cluster 1 and the K8s cluster 2 … … K8s cluster n are first registered on a control panel of the multi-cluster management software 8022, and the multi-cluster management software 8022 manages cluster distribution of the pods in the workload and the replica number of the pods according to user configuration. Then, according to the configuration on the target application instance, if a label of the cross-cluster application is found, the controller 80262 monitors the ready state of the corresponding workload in the multi-cluster management module, once the label is ready, an externally exposed ALB is created for the workload, the ALB mounts the IP address of the credit granting network card corresponding to the pod exposed on each cluster one by one, and then judges whether the ALB needs to bind the public network according to the configuration, and configures the domain name.

For example, the CIDR of subnet 1 is 10.0.16.0/22, and after configuring the network card, the following records may be recorded in the route of resource unit 1:

10.0.16.0/22dev eth2 proto key scan link src 10.0.17.225, wherein 10.0.17.225 (IP 1 shown in FIG. 8) is the IP address of the network card corresponding to resource unit 1.

If subnet 2 is added newly during capacity expansion, e.g., the CIDR of subnet 2 is 10.0.64.0/22, subnet 2 is required to access the exposed resource unit 3. The following records may be recorded in the route of the resource unit 4 after the network card is configured:

10.0.64.0/22dev eth2 proto kernel scope link src 10.0.64.3

where 10.0.64.3 (IP 2 shown in FIG. 8) is the network card IP address to which resource unit 4 corresponds. The second network controller (608 in fig. 6) plug-in, which may be implemented through the K8s API, automatically configures, after creating the above network card, to automatically add the following routes on this resource unit 4:

10.0.16.0/22via 10.0.64.1dev eth2

wherein 10.0.16.0/22 is the CIDR of subnet 1, 10.0.64.1 is the network card IP address corresponding to resource unit 3.

The method can be realized by setting a main operator plug-in on the main cluster 802 and setting a daemon operator plug-in on the K8s sub-cluster respectively, and the daemon operator can be set on one pod on each node and is responsible for controlling resource configuration on each node.

According to the method provided by the embodiment of the disclosure, a multi-cluster Kubernets controller mechanism is utilized, and multi-cluster registration and scheduling management of a bottom layer is performed based on multi-cluster management software, so that the problems of cross-cluster network automatic scheduling and getting through and multi-subnet mutual communication among cross VPCs are solved.
