detailed description

In order to facilitate the understanding of the technical solutions of the embodiments of the present application, some technical terms involved in the embodiments of the present application are described below.

Kubernetes (referred to as k8s) is a container-based cluster management platform, and a kubernetes cluster can include a master node (Master Node) and multiple computing nodes (Work Node) that communicate with the master node respectively. Among them, the master node can be used to manage and control multiple computing nodes. A computing node is a workload node, and each computing node can be deployed with at least one container group (Pod), and each pod group can encapsulate one or more containers (Containers) for carrying software programs.

A Pod is the basic unit of operation of Kubernetes and the smallest unit of deployment that can be created, debugged, and managed. In addition, multiple containers (Containers) located in the same Pod can share network resources (eg, IP addresses). For example, when the first Pod includes 3 containers, and the first Pod has a first IP address, the 3 containers located on the first Pod share the first IP address.

kata is an open source container project that aims to unify the security benefits of virtual machines with the speed and manageability of containers. In addition, kata is obtained by merging two existing open source projects, Intel Clear Containers and Hyper runV, so that kata solves the security and isolation problems of traditional container shared kernels.

kata-runtime is a component of kata, and kata-runtime is used to process all commands specified by the OCI runtime specification and start a kata-shim instance when an OCI (Oracle Call Interface) compatible container is running. Among them, kata-shim is also a component in kata, and kata-shim is used to monitor the container process.

Yaml (Yet another markup language, still a markup language) is a language dedicated to writing configuration files. In addition, Yaml is particularly suitable for expressing or editing data structures, various configuration files, dumping debug content, document outlines, and more. In addition, Yaml is more suitable for expressing hierarchical data structures and for expressing related data. It should be noted that the configuration files written using Yaml are all files with the suffix of .yml.

In the research of the virtual machine computing resources corresponding to the Pod, the inventor found that the user can pre-specify the container computing resource requirements (that is, the container computing resource peak) of each container in the virtual machine, so that the virtual machine can be installed on the virtual machine in the future. The sum of the container computing resource requirements of all the deployed containers is determined as the virtual machine computing resource requirement of the virtual machine. However, because the actual amount of computing resources consumed by each container at different running times is different, it is almost impossible for all containers in the virtual machine to consume the actual computing resources at the same time. The virtual machine computing resource requirement determined by the sum of the container computing resource requirements of all the containers deployed on the virtual machine is much higher than the actual value of the virtual machine computing resource of the virtual machine, which is easy to cause waste of computing resources.

For example, when container 1 and container 2 are deployed on the virtual machine, the container computing resource requirement of container 1 is 2C4G, and the container computing resource requirement of container 2 is 2C4G, the container computing resource requirement of container 1 can be 2C4G and the container computing resource requirement of container 2 The sum of the container computing resource requirement 2C4G is 4C8G, which is determined as the virtual machine computing resource requirement of the virtual machine. In addition, if the actual computing resources consumed by container 1 and container 2 cannot reach the maximum computing resources at the same time, and the peak value of the actual computing resources of the virtual machine is 3C6G, then the actual peak computing resources of the virtual machine 3C6G is lower than the above calculation The computing resource requirement of the obtained virtual machine is 4C8G, so that there is always at least 1C2G of computing resources in the virtual machine in an idle state, which leads to a waste of computing resources.

In order to solve the above technical problem, an embodiment of the present application provides a computing resource allocation method. The method includes: after starting a virtual machine, obtaining a first configuration file provided by a user; after determining that the first configuration file includes virtual machine computing resources When required, first determine the computing resources to be hot-plugged of the virtual machine according to the computing resource requirements of the virtual machine in the first configuration file, and then hot-plug the computing resources to be hot-plugged into the virtual machine, so that the hot-plugged computing resources are hot-plugged. A virtual machine can have sufficient computing resources to meet the computing resource requirements of the containers deployed on it.

It can be seen that, because the computing resource requirements of the virtual machine in the first configuration file are set by the user according to the actual computing resource requirements of the virtual machine, the computing resources to be hot-plugged determined based on the computing resource requirements of the virtual machine can be used without wasting computer resources. The virtual machine can meet the actual computing resource requirements of the virtual machine on the premise of resources, so that the hot-plugged virtual machine can provide sufficient computing resources for the containers deployed on it without wasting computer resources, thus avoiding the waste of computing resources.

In order to make those skilled in the art better understand the solutions of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described The embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Method embodiment

Referring to FIG. 1 , which is a flowchart of a computing resource allocation method provided by an embodiment of the present application.

The computing resource allocation method provided by the embodiment of the present application includes S101-S106:

S101: Start the virtual machine.

A virtual machine refers to a computing node in k8s, and at least one container group Pod can be deployed on the virtual machine. Among them, a Pod can encapsulate at least one container. It can be seen that multiple containers can be deployed on a virtual machine. For example, N containers can be deployed on a virtual machine, and N is a positive integer.

In addition, since the computing resources required for the virtual machine to start are relatively small, in order to ensure that the virtual machine can be started normally, a preset standard allocation resource can be allocated to the virtual machine in advance, so that the virtual machine can use the preset standard to allocate resources Complete boot. The preset standard allocation resources refer to the minimum computer resources required in the running process of the virtual machine. In addition, the preset standard allocation resource can be preset.

S102: Obtain the first configuration file provided by the user.

The first configuration file records the computing resource requirements specified by the user for the virtual machine (eg, computing resource requirements of the virtual machine, computing resource requirements of the container, etc.). For example, the first configuration file may be the yaml configuration file entered by the user in k8s.

The first configuration file may include virtual machine computing resource requirements and/or container computing resource requirements. The computing resource demand of the virtual machine refers to the peak computing resource demanded by the virtual machine during the running process of the virtual machine. The computing resource demand of a container refers to the peak computing resource demanded by the container during the running process of the container.

It should be noted that, in most cases, the first configuration file usually definitely includes the computing resource requirements of the container, so this embodiment of the present application will use the first configuration file to include the computing resource requirements of the virtual machine and the computing resources of the container, or the first configuration file The configuration file includes container computing resource requirements as an example.

It should also be noted that the embodiments of the present application do not limit computing resources. For example, computing resources may include a memory and a central processing unit (central processing unit, CPU).

Based on the above content, in the embodiment of the present application, when the user wants to directly specify the peak value of computing resources of the virtual machine corresponding to the Pod, the user can write the peak value of computing resources of the virtual machine as the computing resource requirement of the virtual machine into the first configuration file, So that the computing resource peak value of the virtual machine can be subsequently known based on the computing resource requirements of the virtual machine existing in the first configuration file. Similarly, when the user wants to directly specify the computing resource peak value of each container deployed in the virtual machine, the user can write the computing resource peak value of each container as the container computing resource requirement of the container into the first configuration file, so that subsequent The peak value of computing resources of each container deployed in the virtual machine can be known based on the computing resource requirements of the containers existing in the first configuration file.

It should be noted that the embodiment of the present application does not limit the execution order of S101 and S102. S101 and S102 may be executed sequentially (as shown in FIG. 1 ), or S102 and S101 may be executed sequentially, or S101 and S102 may be executed simultaneously.

S103: Determine whether the first configuration file includes the computing resource requirements of the virtual machine; if yes, execute S104; if not, execute S105.

In this embodiment of the present application, after the first configuration file is obtained, it can be determined whether the first configuration file includes the computing resource requirements of the virtual machine; if it does, it can be determined that the user has directly specified the peak computing resource of the virtual machine corresponding to the Pod, Therefore, the computing resources that should be allocated to the virtual machine can be determined directly according to the computing resource requirements of the virtual machine existing in the first configuration file; if not included, it can be determined that the user has only specified the computing resources of each container deployed in the virtual machine. Therefore, in order to ensure that the computer resources allocated to the virtual machine can meet the computing resource overhead of all the containers deployed on it, the sum of the container computing resources of all the containers deployed on it can be determined as the virtual machine computing resources of the virtual machine. resource requirements.

In addition, the embodiment of the present application also provides an implementation of S103, which is specifically: firstly parse the first configuration file to obtain the parsing result; and then determine whether there is a virtual machine computing resource requirement of the virtual machine in the parsing result , if it exists, it is determined that the first configuration file includes the computing resource requirement of the virtual machine; if it does not exist, it is determined that the first configuration file does not include the computing resource requirement of the virtual machine. The parsing result refers to a result obtained by performing parameter parsing on the first configuration file, and the parsing result may include computing resource requirements of a virtual machine and/or computing resource requirements of a container. It should be noted that the embodiment of the present application does not limit the parsing process of the first configuration file. For example, the first configuration file may be obtained by parsing by k8s.

S104: Determine the computing resources to be hot-plugged of the virtual machine according to the computing resource requirements of the virtual machine in the first configuration file.

The computing resources to be hot-plugged refer to computing resources that need to be hot-plugged into the virtual machine after the virtual machine is started, so that the hot-plugged virtual machine can meet the computing resource overhead of starting and running all the containers deployed on it.

The embodiment of the present application also provides an implementation of S104, which specifically includes: analyzing the first configuration file to obtain computing resource requirements of the virtual machine; and determining computing resources to be hot-plugged for the virtual machine according to the computing resource requirements of the virtual machine.

Based on this, in the embodiment of the present application, after the first configuration file is obtained, the computing resource requirements of the virtual machine can be obtained by parsing the first configuration file, and then the computing resource requirements of the virtual machine obtained by the analysis can be used to determine the computing resource requirements of the virtual machine. Computing resources to be hot-plugged.

In addition, the embodiment of the present application does not limit the implementation process of determining the computing resource to be hot-plugged based on the computing resource requirement of the virtual machine, which specifically includes: directly determining the computing resource requirement of the virtual machine as the computing resource to be hot-plugged of the virtual machine.

In some cases, in addition to the user specifying the virtual machine computing resource overhead of the virtual machine, the operation and maintenance personnel (that is, the technician who maintains the running process of the virtual machine) will also specify the virtual machine basic computing resource overhead of the virtual machine. Therefore, in order to satisfy the computing resource requirements of the user and the operation and maintenance personnel for the virtual machine at the same time, the computing resource to be hot-plugged of the virtual machine can be determined by referring to the computing resource overhead specified by the two at the same time. Based on this, the embodiment of the present application also provides an implementation of S104, which specifically includes S1041-S1044:

S1041: Obtain a second configuration file.

The second configuration file refers to a parameter configuration file provided by the operation and maintenance personnel for maintaining the running process of the virtual machine, and the second configuration file may include basic resource requirements of the virtual machine. The basic resource requirement of the virtual machine refers to the computing resource overhead necessary for maintaining the running process of the virtual machine.

S1042: Determine that the basic resource requirement of the virtual machine meets the preset condition; if yes, execute S1043; if not, execute S1044.

The preset condition is used to represent a condition that needs to be satisfied by reference to the basic resource requirements of the virtual machine when determining the computing resource to be hot-plugged, and the preset condition is preset.

In practical applications, the basic resource requirements specified by the operation and maintenance personnel for the virtual machine should not exceed the preset standard allocation resources (that is, the computing resources actually required when the virtual machine is started), so that after the virtual machine is started, the virtual machine It can continue to use the released preset standard allocation resources to offset the basic resource requirements of the virtual machine, so in this case, it is not necessary to consider the impact of the basic resource requirements of the virtual machine on hot-plug computing resources; however, in some special cases , the basic resource requirements specified by the operation and maintenance personnel for the virtual machine will exceed the preset standard allocation resources, so that after the virtual machine is started, the virtual machine cannot use the released preset standard allocation resources to completely offset the basic resource requirements of the virtual machine. Therefore, in this case, the influence of the basic resource requirements of virtual machines on hot-plug computing resources should be considered.

In order to meet the computing resource requirements of the virtual machine in the above two situations, a preset condition may be set in advance such that the basic resource requirements of the virtual machine are higher than the preset standard to allocate resources, so that the above two conditions can be determined based on the preset conditions. a situation.

Based on the relevant content of S1042 above, it can be known that after obtaining the basic resource requirements of the virtual machine, it can be determined whether the basic resource requirements of the virtual machine are higher than the preset standard to allocate resources; if it is higher, it can be determined that after the virtual machine is started The released preset standard allocation resources cannot meet the basic resource requirements of the virtual machine. Therefore, in order to meet the basic resource requirements specified by the operation and maintenance personnel and the computing resource requirements of the virtual machine specified by the user at the same time, the basic resource requirements of the virtual machine and the virtual machine can be integrated. The computing resources to be hot-plugged of the virtual machine are jointly determined according to the computing resource requirements of the virtual machine; if it is not higher than that, it can be determined that the preset standard allocation resources released after the virtual machine is started can meet the basic resource requirements of the virtual machine, so in order to save computing resources resources, the computing resources to be hot-plugged of the virtual machine may be determined only by considering the computing resource requirements of the virtual machine specified by the user.

S1043: Determine the computing resources to be hot-plugged of the virtual machine according to the basic resource requirements and the computing resource requirements of the virtual machine in the first configuration file.

In the embodiment of the present application, after it is determined that the basic resource requirements specified by the operation and maintenance personnel are higher than the preset standard allocation resources, it can be determined that the existing preset standard allocation resources in the virtual machine can only offset a part of the basic resource requirements. In order to save computing resources, the computing resources to be hot-plugged of the virtual machine may be determined according to the unoffset part of the basic resource requirements and the computing resource requirements of the virtual machine specified by the user.

Based on this, the embodiment of the present application provides an implementation of S1043, which specifically includes: allocating resources according to basic resource requirements and preset standards, and obtaining a resource difference; calculating according to the resource difference and the virtual machine in the first configuration file Resource requirements, determine the computing resources to be hot-plugged for the virtual machine.

Among them, the resource difference is used to represent the unoffset part of the basic resource requirements specified by the operation and maintenance personnel.

Based on the relevant content of the above S1043, after it is determined that the basic resource requirements specified by the operation and maintenance personnel are higher than the preset standard allocation resources, the difference between the basic resource requirements and the preset standard allocation resources can be calculated to obtain the resource difference; The resource difference and the computing resource requirements of the virtual machine specified by the user are summed to determine the computing resources to be hot-plugged for the virtual machine, so that the sum of the computing resources to be hot-plugged and the resources allocated by the preset standard can jointly satisfy the operation and maintenance personnel. The specified basic resource requirements and the user-specified computing resource requirements of the virtual machine, so that the virtual machine after the hot-plug is completed can meet the computing resource requirements of the operation and maintenance personnel and the user for the virtual machine at the same time.

S1044: Determine the computing resources to be hot-plugged of the virtual machine according to the computing resource requirements of the virtual machine in the first configuration file.

Based on the relevant contents of S1041 to S1044 above, it can be known that after obtaining the computing resource requirements of the virtual machine specified by the user, it is first determined whether the basic resource requirements specified by the operation and maintenance personnel are higher than the preset standard allocated resources released after the virtual machine is started. , if it is higher than the computing resource requirements of the virtual machine specified by the user, the basic resource requirements specified by the operation and maintenance personnel, and the calculation of allocating resources according to the preset standard, the computing resources to be hot-plugged of the virtual machine can be determined, so that the computing resources to be hot-plugged can be determined. The sum of resources and preset standard allocation resources can be no less than the sum of the virtual machine computing resource requirements specified by the user and the basic resource requirements specified by the operation and maintenance personnel, so that the virtual machine after the hot swap can meet the requirements of the operation and maintenance personnel at the same time. and the user's computing resource requirements for the virtual machine; if it is not higher than that, the computing resources to be hot-plugged for the virtual machine can be determined directly according to the computing resource requirements of the virtual machine specified by the user. The sum of the standard allocation resources can be no less than the sum of the computing resource requirements of the virtual machine specified by the user and the basic resource requirements specified by the operation and maintenance personnel, so that the virtual machine after the hot-plug can meet the requirements of the operation and maintenance personnel and users at the same time. The computing resource requirements of the virtual machine.

Based on the relevant content of S104 above, it can be known that after determining that the virtual machine computing resource requirements of the virtual machine exist in the first configuration file, the virtual machine computing resource requirements of the virtual machine can be directly determined as the hot-plug computing of the virtual machine. resources, which are specifically: when the computing resource requirements of the virtual machine include memory requirements and CPU requirements, the memory requirements of the virtual machine can be directly determined as the memory to be hot-plugged of the virtual machine, and the CPU requirements of the virtual machine can be directly determined as The CPU to be hot-plugged for this virtual machine. Among them, because the virtual machine computing resource requirements of the virtual machine are directly specified by the user according to the actual computing resource requirements of the virtual machine, the computing resources to be hot-plugged determined based on the computing resource requirements of the virtual machine can be used without wasting computer resources. Therefore, the hot-plugged virtual machine can provide sufficient computing resources for the containers deployed on it without wasting computer resources, thus avoiding the waste of computing resources.

S105: Determine the computing resources to be hot-plugged of the virtual machine according to the computing resource requirements of the container in the first configuration file.

The embodiment of the present application also provides an implementation of S105, which specifically includes: analyzing the first configuration file to obtain the computing resource requirements of the container; and determining the computing resources to be hot-plugged of the virtual machine according to the computing resource requirements of the container.

Based on this, in the embodiment of the present application, after the first configuration file is obtained, the container computing resource requirements of each container deployed on the virtual machine can be obtained by parsing the first configuration file, and then the container computing resource requirements of each container deployed on the virtual machine can be obtained by using the first configuration file. The container computing resource requirements of each container of the virtual machine are determined, and the computing resources to be hot-plugged of the virtual machine are determined.

In addition, the embodiment of the present application does not limit the implementation process of determining the computing resources to be hot-plugged based on the container computing resource requirements. When the resource demand reaches the container computing resource demand of the Nth container, the computing resources to be hot-plugged of the virtual machine are obtained according to the sum of the container computing resource demand of the first container to the container computing resource demand of the Nth container.

Based on this, after it is determined that there are container computing resource requirements of N containers deployed on the virtual machine in the first configuration file, the container computing resource requirements of the first container can be calculated from the container computing resource requirements of the first container to the container computing resource requirements of the Nth container. Adding the sum to obtain the computing resources to be hot-plugged of the virtual machine, which is specifically: determining the sum of the computing resource requirements of the container from the first container to the computing resource requirements of the N-th container as the computing resources to be hot-plugged of the virtual machine resource.

In addition, based on the relevant content of "basic resource requirements specified by operation and maintenance personnel" in S104, this embodiment of the present application also provides a possible implementation of S105, which specifically includes S1051-S1054:

S1051: Obtain a second configuration file.

S1052: Determine that the basic resource requirement of the virtual machine meets the preset condition; if yes, execute S1053; if not, execute S1054.

S1053: Determine the computing resources to be hot-plugged of the virtual machine according to the basic resource requirements and the container computing resource requirements in the first configuration file.

S1054: Determine the computing resources to be hot-plugged of the virtual machine according to the computing resource requirements of the container in the first configuration file.

It should be noted that the relevant contents of S1051 to S1054 are respectively similar to the relevant contents of S1041 to S1044 above, and it is only necessary to replace the “computing resource requirement of virtual machine” in S1041 to S1044 above with “computing resource requirement of container”. .

Based on the relevant content of S1051 to S1054 above, it can be known that after obtaining the container computing resource requirements specified by the user, it is first determined whether the basic resource requirements specified by the operation and maintenance personnel are higher than the preset standard allocation resources released after the virtual machine is started. If it is higher than that, the computing resources to be hot-plugged of the virtual machine can be determined according to the computing resource requirements of the container specified by the user, the basic resource requirements specified by the operation and maintenance personnel, and the operation of allocating resources according to the preset standard, so that the computing resources to be hot-plugged are different from the computing resources to be hot-plugged. The sum of the resources allocated by the preset standard can be no less than the sum of the container computing resource requirements specified by the user and the basic resource requirements specified by the operation and maintenance personnel, so that the virtual machine after the hot-plug can meet the requirements of the operation and maintenance personnel and users at the same time. The computing resource requirements of the virtual machine; if not higher, the computing resources to be hot-plugged of the virtual machine can be determined directly according to the computing resource requirements of the container specified by the user, which can also make the computing resources to be hot-plugged and the preset standard allocation resources The sum of the container computing resource requirements specified by the user and the basic resource requirements specified by the operation and maintenance personnel can be no less than the sum of the computing resource requirements of the container specified by the user and the basic resource requirements specified by the operation and maintenance personnel, so that the virtual machine after the hot swap can meet the computing resources of the operation and maintenance personnel and the user. need.

Based on the relevant content of the above S105, it can be seen that after it is determined that the first configuration file does not include the computing resource requirements of the virtual machine of the virtual machine, but includes the computing resource requirements of all the containers deployed on the virtual machine, the virtual machine can be directly used. The sum of the container computing resource requirements of all containers deployed on the virtual machine is used to determine the computing resources to be hot-plugged for the virtual machine, so that the determined computing resources to be hot-plugged can meet the maximum computing resource overhead of all containers on the virtual machine.

S106: Hot-plug the computing resources to be hot-plugged of the virtual machine to the virtual machine.

In this embodiment of the present application, after obtaining the computing resources to be hot-plugged of the virtual machine, the obtained computing resources to be hot-plugged can be directly hot-plugged into the virtual machine, so that the virtual machine can meet the requirements of all containers deployed on it. Computational resource overhead during operation.

In some cases, after hot-plugging the computing resource to be hot-plugged into the virtual machine, a container on the virtual machine may be started, and a container control group (control groups, cgroups) of the container may be configured.
