The flowcharts used in this application illustrate operations implemented according to some embodiments of the present application. It should be understood that the operations of the flow diagrams may be performed out of order, and steps without logical context may be performed in reverse order or simultaneously. One skilled in the art, under the guidance of this application, may add one or more other operations to, or remove one or more operations from, the flowchart.
In addition, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
Before the technical scheme of the application is introduced, the technical terms related to the application are explained firstly:
kubernetes: the K8s is an open-source application for managing containerization on multiple hosts in a cloud platform, and Kubernets aims to make the application for deploying containerization simple and efficiently provide a mechanism for application deployment, planning, updating and maintenance.
A container: and the environment for running the application program encapsulates the relevant information required by the application program.
Pod: is a combination of containers, referred to herein as a container collection, for one or more applications.
The control of the container bandwidth can be realized through a bandwidth plug-in the prior art, but the control has great defects in flexibility and is difficult to apply in a practical environment, and the defects include the following points:
first, only control can be performed through a unified configuration file, each container cannot be controlled individually, and different services in actual use have different bandwidth requirements and priorities, so that the existing method cannot flexibly control the container bandwidth.
The second, current approach is to create a bandwidth rule when creating a container, and the bandwidth cannot be adjusted after creating the container, so that it cannot meet the requirement of dynamically adjusting the container bandwidth.
Thirdly, the configuration files are distributed on each server, so that the configuration files cannot be modified in a uniform manner, and once the bandwidth needs to be adjusted, the workload is very heavy.
Based on this, the embodiment of the present application provides a method for adjusting a container bandwidth, which adjusts bandwidth indication information of a container in a configuration file of a container set, and adjusts a bandwidth of a target container according to the configuration file, thereby enhancing control over a network bandwidth, flexibly setting a container bandwidth according to a service requirement, and implementing fine-grained adjustment on a single container; the bandwidth of the container can be dynamically adjusted according to actual requirements after the container is created; only the bandwidth indication information of the target container in the configuration file of the container set needs to be adjusted, so that the workload is reduced; meanwhile, the bandwidth of the container can be dynamically adjusted under the condition of not stopping the container service according to the change of the running condition, so that more flexible bandwidth control is realized.
Fig. 1 shows an architecture schematic diagram of a container bandwidth adjustment system provided in an embodiment of the present application, and as shown in fig. 1, the container bandwidth adjustment system includes: the system comprises a control server 100 and at least one application server 200, wherein the control server 100 is a control node in Kubernets, and the at least one application server 200 is a working node in Kubernets. An API (Application Programming Interface) service Server runs on the Application Server 200, and a container of an Application runs on at least one Application Server 200. Each application server 200 may run a plurality of containers (i.e., Pod) of the application program, and the containers of the application programs may have a corresponding relationship with the application server 200, that is, when downlink data is sent by a client of a certain application program, it actually accesses the container corresponding to the application program on the application server 200.
The API Server provides HTTP Rest interfaces such as adding, deleting, checking and watch of various resource objects in Kubernets, and is a data bus and a data center of the whole system. In practical applications, sending a resource creation or deletion request to the APIServer of Kubernetes may create a container for an application on the application server 200 or delete a corresponding container.
In addition, in the present application, each application server 200 may further be configured with a Container Network Interface (CNI) plug-in, and the CNI plug-in may also be configured with a bandwidth plug-in.
The following describes in detail a method for adjusting a container bandwidth according to an embodiment of the present application, with reference to the content described in the system for adjusting a container bandwidth shown in fig. 1.
Fig. 2 is a schematic flowchart illustrating a first flow chart of a method for adjusting a container bandwidth according to an embodiment of the present application, where as shown in fig. 2, the method for adjusting the container bandwidth includes:
s101, the control server obtains the input editing operation of the container set aiming at the target application.
S102, the control server adjusts bandwidth indication information of a target container corresponding to the target application in the configuration file of the container set according to the editing operation.
Wherein a container set, Pod, is a combination of containers for one or more applications. The configuration file of the container set comprises bandwidth indication information of each container in the Pod, and the bandwidth indication information is used for bandwidth parameters of the container.
Specifically, when the container bandwidth of the target application needs to be adjusted, the developer may input an editing operation on the container set of the target application on the control server side to adjust the bandwidth indication information of the target container in the configuration file of the container set, that is, the control server adjusts the bandwidth indication information of the target container in the description file of the container set according to the input editing operation on the container set of the target application, where the bandwidth indication information is used to request the target application server to adjust the bandwidth of the target container, and the target container runs on the target application server.
Optionally, the configuration file includes any one of the following files:
the method comprises the steps of describing a container set, a security dictionary, a first configuration file and a second configuration file; wherein the first configuration file is stored in a configuration storage service of the control server, and the second configuration file is stored in the external device.
Wherein, the container set has a description file, and the bandwidth indication information of the target container can be adjusted in the description file of the container set.
The secure dictionary represents declaration in the form of a secure dictionary, wherein a secure dictionary is a resource type for storing authentication information required by a workload, sensitive information of a key, and the like.
The configuration storage service may be a service for centrally storing and managing application configurations, for example, zookeeper, etcd, that is, the first configuration file may store bandwidth indication information of the container, and the bandwidth indication information of the target container may be adjusted by adjusting the bandwidth indication information of the target container in the first configuration file.
The external device may be a device other than the control server, and the bandwidth indication information of the target container in the second configuration file stored in the external device may be adjusted by the downlink data.
Illustratively, the bandwidth indication information may be in the form of a bandwidth annotation and/or a bandwidth tag.
Wherein the bandwidth annotation indicates that the bandwidth of the target container is declared in an annotated manner; the bandwidth label indicates that the bandwidth of the target container is declared in a label manner. That is, the bandwidth of the target container may be declared in the description file, the security dictionary, the first configuration file, and the second configuration file of the container set in the form of a bandwidth annotation and/or a bandwidth tag, respectively.
Optionally, the target application is any one of the following applications:
newly created applications, deleted applications, applications with changed access priority, applications with abnormal access; the application with abnormal access is the application with the access frequency greater than or equal to the preset frequency in the preset time period.
The bandwidth of the target application server is limited, and the target application server runs a plurality of containers to compete for bandwidth resources, so that when the target application is a newly created application, the default container bandwidth of the application can be increased so that a user can smoothly access the application.
Similarly, when the target application is a deleted application, in order to enable the user to smoothly access other applications corresponding to the target application server, the container bandwidth of the deleted application may be set to 0, so that more bandwidth may be left for the containers of the other applications.
The application with the changed access priority refers to that according to actual requirements, the current access priority of the application is changed compared with the historical access priority, for example, the historical access priority of the application A is higher than that of the application B, and in order to enable a user to smoothly access the application A, the container bandwidth allocated to the application A is larger than that of the application B; and as the number of users of the application B is more and more, the number of users of the application A is less and less, which shows that the current access priority of the application A is lower than that of the application B, and in order to enable users to smoothly access the application B, the container bandwidth which can be allocated to the application A is smaller than that of the application B, so that the bandwidth is isolated according to the access priority of the application.
The application with abnormal access is the application with the access times larger than or equal to the preset times in the preset time period, and in some cases, when the external traffic sharply increases, that is, the application is attacked by malicious external attacks, in order to avoid such a situation of frequently requesting the application, the container bandwidth of the application can be reduced.
Optionally, step S102 specifically includes:
and S1021, changing the transmission rate of the target container in the description file according to the editing operation.
And S1022, adjusting the bandwidth indication information of the target container in the description file according to the transmission rate.
The initial transmission rate of the target container is stored in the description file, the transmission rate of the target container in the description file can be changed according to editing operation, and then bandwidth indicating information of the target container is adjusted and obtained according to a preset conversion relation between the transmission rate and the bandwidth, wherein the bandwidth indicating information is used for indicating the bandwidth parameters of the target container.
The transmission rate of the target container includes an uplink transmission rate (english name: Ingress) and a downlink transmission rate (english name: Egress). The uplink transmission rate is also referred to as an upload rate, and the downlink transmission rate is also referred to as a download rate.
The following linux program is an example of a description file for a container set:
apiVersion:v1
kind:Pod
metadata:
name:qos
namespace:ls1
annotations:
ovn.kubernetes.io/ingress_rate:"3"
ovn.kubernetes.io/egress_rate:"1"
spec:
containers:
-name:qos
image:nginx:alpine
therefore, the bandwidth indication information of the target container is embodied in the description file in the form of bandwidth annotation, and the transmission Rate of the target container is changed by adding a customized option of an uplink transmission Rate ovn.
S103, the target application server calls an application service interface in the control server to acquire a configuration file of the container set of the target application.
When a user accesses the network through a client of the target application, the user actually accesses the target container on the target application server.
The application service interface is APIServer in the embodiment of fig. 1. The target application Server calls an API Server in the control Server to monitor and acquire the configuration file of the container set.
Optionally, the target application server may call the application service interface through the bandwidth plug-in to obtain a configuration file of the container set of the target application.
S104, the target application server obtains bandwidth indication information of a target container corresponding to the target application in the configuration file.
S105, the target application server adjusts the bandwidth of the target container according to the bandwidth parameter of the target container.
After the target application server obtains the configuration file, bandwidth indicating information of the target container can be inquired and determined in the configuration file, the bandwidth indicating information is used for indicating the bandwidth parameter of the target container, and then the bandwidth of the target container can be adjusted according to the bandwidth parameter of the target container.
Optionally, after monitoring the configuration file, the target application server may obtain bandwidth indication information of the target container in the configuration file through the bandwidth plug-in.
The method for adjusting the bandwidth of the container provided by the embodiment comprises the following steps: the control server acquires an input editing operation aiming at a container set of a target application, and adjusts bandwidth indication information of a target container corresponding to the target application in a configuration file of the container set according to the editing operation, wherein the bandwidth indication information is used for indicating a bandwidth parameter of the target container, the bandwidth indication information is used for requesting the target application server to adjust the bandwidth of the target container, the target container runs on the target application server, the target application server calls an application service interface in the control server to acquire the configuration file of the container set of the target application, the bandwidth indication information of the target container corresponding to the target application in the configuration file is acquired, the bandwidth indication information is used for indicating the bandwidth parameter of the target container, and the bandwidth of the target container is adjusted according to the bandwidth parameter of the target container. The application has the following beneficial effects: by adjusting the bandwidth indication information of the target container in the configuration file of the container set and adjusting the bandwidth of the target container according to the configuration file, the control on the network bandwidth is enhanced, the container bandwidth can be flexibly set according to the service requirement, and the fine-grained adjustment of a single container is realized.
Illustratively, the bandwidth parameter includes an upstream bandwidth parameter, and adjusting the bandwidth of the target container according to the bandwidth parameter includes the steps shown in fig. 3. Fig. 3 shows a second flowchart of the method for adjusting the bandwidth of the container according to the embodiment of the present application, and as shown in fig. 3, the adjusting, by the target application server, the bandwidth of the target container according to the bandwidth parameter specifically includes:
s201, the target application server determines a target network card of the target container on the target application server according to a preset corresponding relation between the container and the network card.
The target application server is provided with a plurality of network cards, the plurality of containers running on the target application server and the plurality of network cards have corresponding relations, and the network cards are used for receiving relevant data of the corresponding containers from external equipment, such as response data of the target application.
The preset corresponding relationship between the container and the network card can be stored in the target application server in a table form, and the target application server inquires the corresponding relationship to determine the target network card corresponding to the target container.
It should be noted that the network card on the target application server may be a virtual network card or an entity network card, which is not limited in this embodiment.

And when the target application server receives the configuration file of the container set, adjusting the uplink bandwidth of the target network card according to the uplink bandwidth information, wherein the uplink bandwidth of the target network card is the uplink bandwidth of the target container.
The following linux program is an example of setting the upstream bandwidth of the target network card:
tcqd add dev { container network card }
root handle 1: tbf rate { ingress Bandwidth } burst { ingress Bandwidth }
latency 50ms
Therefore, according to the preset conversion relation between the transmission rate and the bandwidth, the uplink bandwidth parameter is converted into the uplink transmission rate, then a Transmission Control (TC) command under linux is adopted to add a queue rule (qdisc) to the target network card and set the queue rule as a bandwidth control algorithm (token packet filter, tbf), a TC module addition rate parameter and a burst rate burst parameter of the linux kernel are called, and the TC module sets the uplink transmission rate of the target network card according to the uplink transmission rate, so that the adjustment of the bandwidth of the target network card is realized.
The burst rate burst refers to a rate allowed to exceed a rate in a short time, and in general, the burst rate burst and the rate may be set to be the same, that is, the burst rate burst and the rate are adjusted according to an uplink transmission rate; latency refers to the maximum waiting time after the rate of the data packet is limited by the bandwidth control, and the data packet which is not processed is discarded after the maximum waiting time.

Therefore, the control on the uplink network bandwidth is enhanced, the uplink bandwidth of the container can be flexibly set according to the service requirement, and the fine-grained adjustment on the uplink bandwidth of a single container is realized.
Illustratively, the bandwidth parameter includes a downlink bandwidth parameter, and adjusting the bandwidth of the target container according to the bandwidth parameter includes the steps shown in fig. 4. Fig. 4 is a schematic flowchart illustrating a third flow chart of a method for adjusting a container bandwidth provided in an embodiment of the present application, where as shown in fig. 4, a target application server adjusts a bandwidth of a target container according to a bandwidth parameter, and specifically includes:
s301, the target application server determines a target network card of the target container on the target application server according to a preset corresponding relation between the container and the network card.

S303, the target application server adjusts the downlink bandwidth of the kernel module according to the downlink bandwidth parameter, wherein the downlink bandwidth of the kernel module is the downlink bandwidth of the target container.
Redirection means redirecting the received downlink data to other locations by various methods, where the kernel module is a special kernel device (english name: Intermediate Functional Block) on the target application server.
Specifically, the target application server may redirect the downlink data from the target network card to the kernel module in the target application server through the preset classifier, that is, when the user sends the downlink data through the client of the target application, the kernel module in the target application server sends the downlink data to the other device. And then, the downlink bandwidth of the kernel module is adjusted according to the downlink bandwidth parameters, so that the adjustment of the downlink bandwidth of the target container is realized.
The following linux program is an example of setting the downstream bandwidth of the kernel module:
# redirect downstream data to ifb0
tcqdisc add dev { container network card } ingress handle ffff:
tc filter add dev { container network card } parent ffff protocolippo 0u32 match u 3200 flowidffff action miscorrected dev if 0
# setting Filter
tc filter add dev ifb0 parent 1:0prio 5protocol ip u32
# set the egr bandwidth
tc class add dev ifb0 parent 1:0class id 1:1tbf rate { resources bandwidth } burst { resources bandwidth }
Therefore, the downlink bandwidth parameters are converted into the downlink transmission rate according to the preset conversion relation between the transmission rate and the bandwidth, then a TC module is adopted to add a classifier handle to the target network card, the identification of the handle is set to fff, the downlink data are redirected onto the kernel module ifb, then a filter ip is added onto the kernel module, the filter ip can further send all the intercepted downlink data to the kernel module ifb, and then the downlink transmission rate of the kernel module ifb is changed according to the downlink transmission rate, so that the adjustment of the downlink bandwidth of the kernel module ifb is realized, wherein the downlink bandwidth of the kernel module is the downlink bandwidth of the target container.
