The service is deployed on the cloud computing platform and operated in different containers, and enterprises can configure resources required by the containers for operating the services according to service requirements. However, the business traffic of an enterprise is not steadily developed, and in order to be able to elastically shrink the container resource according to the sudden fluctuation of the business traffic, the prior art proposes the following two solutions: in the first solution, the cloud computing platform reserves enough buffering resources for each container, so that enough resources can be guaranteed to be available at the highest speed when the traffic flow rises. And the capacity expansion flow is triggered when the service flow rises, the service flow rises by increasing the number of containers, the capacity can be reduced at any time when the load is low, and the maximum full use of the host machine resources is ensured. However, in the first solution, although enough resources can be guaranteed to process the burst traffic at the fastest speed, the resource waste is serious; in the second solution, it generally takes a minute to add a container, and when the traffic volume suddenly increases, the capacity expansion will increase the traffic processing delay.

Detailed Description
In order to reduce service processing delay and guarantee service quality and improve the utilization rate of host machine resources, embodiments of the present invention provide a method, an apparatus, and a medium for adjusting resources based on a container.
First, some terms related to the embodiments of the present invention are explained to facilitate understanding by those skilled in the art.
1. And the container is operated based on the docker mirror image, and the service process is operated in the container.
2. A host, refers to a physical server, which is a carrier for running containers, and each physical server may run multiple containers.
3. Resources, various resources required for the container to run, for example, CPU resources, and the like.
4. An ECU: for describing the CPU capacity units of various types of machines, the per unit ECU capacity is equivalent to 1/80 for the full capacity of a 4-core 8-thread C1 machine of dominant frequency 2.53, i.e., 1ECU equals 1 core CPU capacity.
5. Cord ECU value: each container is assigned a quota of ECUs, by which the user calculates costs and payments. When the host machine resources are distributed, the sum of all container cord ECU configurations is equal to the total ECU available for the host machine.
6. Hard-line ECU value: when the host is idle, the containers may over-utilize the ECU, so the overall container hardwire ECU value is generally greater than or equal to the host total ECU value.
7. Super-matching: on the premise of guaranteeing the service quality of all containers of the host, the container sporadic over quota is allowed to use CPU resources, and the problem of resource demand of service flow burst is solved. Namely: the user configures the vessel with soft ECUs, but the host actually assigns to the vessel hard-wired ECUs.
8. Sharing: since the total number of all container hardwire ECUs is greater than the total number of flex ECUs, all containers actually share a share of buffer resources, minimizing host idle resources.
9. In the description of the embodiments of the invention, the terms "first," "second," and the like are used for descriptive purposes only and not for purposes of indicating or implying relative importance, nor for purposes of indicating or implying order.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
The resource adjusting method based on the container provided by the embodiment of the invention can be applied to a computing device, and the computing device can be expressed in the form of general computing equipment. A computing device 10 according to the present invention is described below with reference to fig. 1. The computing device 10 shown in FIG. 1 is only one example and should not be taken to limit the scope of use and functionality of embodiments of the present invention.
As shown in fig. 1, components of computing device 10 may include, but are not limited to: at least one processor 11, at least one memory 12, and a bus 13 connecting the various system components, including the memory 12 and the processor 11.
Bus 13 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, a processor, or a local bus using any of a variety of bus architectures.
Memory 12 may include readable media in the form of volatile memory, such as Random Access Memory (RAM)121 and/or cache memory 122, and may further include Read Only Memory (ROM) 123.
Memory 12 may also include a program/utility 125 having a set (at least one) of program modules 124, such program modules 124 including, but not limited to: an operating system, one or more application programs, other program modules, and program data, each of which, or some combination thereof, may comprise an implementation of a network environment.
Computing device 10 may also communicate with one or more external devices 14 (e.g., keyboard, pointing device, etc.), with one or more devices that enable a user to interact with computing device 10, and/or with any devices (e.g., router, modem, etc.) that enable computing device 10 to communicate with one or more other computing devices. Such communication may be via an input/output (I/O) interface 15. Moreover, computing device 10 may also communicate with one or more networks (e.g., a Local Area Network (LAN), a Wide Area Network (WAN), and/or a public network, such as the internet) via network adapter 16. As shown, network adapter 16 communicates with other modules for computing device 10 over bus 13. It should be understood that although not shown in the figures, other hardware and/or software modules may be used in conjunction with computing device 10, including but not limited to: microcode, device drivers, redundant processors, external disk drive arrays, RAID systems, tape drives, and data backup storage systems, among others.
Fig. 2 is a schematic view of an application scenario of the container-based resource adjustment method according to the embodiment of the present invention. The user 10 requests the host machine 11 to allocate resources through the terminal device 13 according to the service requirement of the user, and the host machine 11 allocates corresponding container resources to the user according to the user request to operate the container 12 so as to process the user service. In specific implementation, when the user 10 configures resources, such as a CPU capability value (ECU), for its own container, only the normal load condition needs to be considered, for example, the user 10 needs 30 ECUs more than 90% of the time according to its own service evaluation, then the 30 ECUs may be set to be configured for the container cord, the host computer may calculate the service cost according to the 30 ECUs, if the service flow suddenly increases, resources larger than 30 ECUs may be temporarily used, and resources exceeding 30 ECUs are used for free. For the host, since the container is usually used alternately with resources exceeding the soft wire ECU value, the entire host only needs to reserve a small amount of buffer resources. It should be noted that if some services use resources for a long time and exceed the value of the cord ECU configured by the user, minute-level expansion is triggered, that is, the capacity is expanded by increasing the number of containers.
The connection between the terminal device 13 and the host 11 may be via a communication network, which may be a local area network, a wide area network, etc. The terminal device 13 may be a portable device (e.g., a mobile phone, a tablet, a notebook Computer, etc.), or may be a Personal Computer (PC), etc.
The following describes in detail a container-based resource adjustment method provided by an embodiment of the present invention with reference to fig. 1 and fig. 2, and as shown in fig. 3, the method may include the following steps:
s31, receiving a container resource configuration request, wherein the container resource configuration request carries a second resource threshold.
In specific implementation, a user sends a container resource configuration request to a host according to a service operation requirement of the user, wherein the container resource configuration request carries a second resource threshold value, namely a soft ECU value, set by the user according to the service operation requirement of the user.
And S32, the host machine determines a first resource threshold value of the actual available resource of the container according to the second resource threshold value.
After receiving the container resource configuration request, the host determines a first resource threshold value, namely a hard ECU value, of the actual available resource of the container according to a second resource threshold value carried in the container resource configuration request, wherein the first resource threshold value is not less than the second resource threshold value.
And S33, determining the average load of the host machine in the current adjusting period.
And S34, adjusting the first resource threshold value of each container in the next adjustment period according to the average load.
In this way, at the end of each adjustment period, the first resource threshold actually available for each container can be dynamically adjusted by looping through steps S33 and S34.
In specific implementation, if the first resource threshold is set too low, the resource utilization rate of the host is not obviously increased, and if the first resource threshold is set too high, the machine load may be too high, so that the service failure rate and the consumed time of the service in the container are increased. If the average load in the current adjustment period is increased compared to the last adjustment period, decreasing the first resource threshold, otherwise, if the average load in the current adjustment period is decreased compared to the last adjustment period, increasing the first resource threshold. Specifically, if the average load of the host in the current adjustment period is smaller than a first load threshold, increasing the first resource threshold, for example, increasing the first resource threshold according to a first preset proportion; if the average load of the host in the current adjustment period is greater than the second load threshold, the first resource threshold is decreased, for example, the first resource threshold may be decreased according to a second preset proportion.
In specific implementation, the duration of the adjustment period, the first preset proportion, the second preset proportion, the first load threshold and the second load threshold may be set according to empirical values, for example, the adjustment period may be set to 15s, that is, the host calculates the average load of the host in the current adjustment period every 15s, and adjusts the first resource threshold of the actually available resource of each container in the next adjustment period according to the calculation result. The first load threshold may be set to 40% based on empirical values. As for the second load threshold, the item pressure measurement result shows that when the resource utilization rate of most of the services reaches above 70%, the service processing time consumption and the failure rate start to increase, so in the embodiment of the present invention, the upper limit of the second load threshold is 70%, for example, the second load threshold may be set to 65%. The first preset proportion threshold may be set to 10% based on an empirical value, and the second preset proportion may be set to 10% based on an empirical value. For example, when the average load of a host in the current adjustment period is less than 40%, the first resource threshold, i.e., the quota of the hard-line ECU value, of all containers deployed on the host rises by 10%, and when the average load of the host in the current adjustment period is greater than 65%, the first resource threshold, i.e., the quota of the hard-line ECU value, of all containers deployed on the host falls by 10%.
In specific implementation, the hard-line ECU cannot be smaller than the soft ECU, because the soft ECU uses the average resource usage rate after evaluation or pressure measurement according to each service, and in order to ensure the service quality of the service operated in the container, it is necessary to ensure that the resource available to each container is greater than or equal to the soft ECU value at any time.
However, in specific implementation, if the hard-line ECU values of all the containers increase by the first preset ratio, the buffer resources of the entire host may be insufficient, so as to cause a host downtime, and in order to solve the problem, in the embodiment of the present invention, while the first resource threshold is increased according to the first preset ratio, the upper limit value of the adjusted first resource threshold may also be determined according to the second resource threshold and/or the sum of the available resources of the host.
Based on this, in implementation, the upper limit value of the adjusted first resource threshold may be determined in any one of the following manners:
the first mode,
Determining an upper limit value of the adjusted first resource threshold according to the following formula:wherein:
yan upper limit value representing the adjusted first resource threshold;
x represents the second resource threshold;
m represents the sum of the available resources of the host.
If M is 9, the flexible wire ECU value is 9, and the upper limit of the adjustment of the hard wire ECU value is 9 ECU; the flexible wire ECU value is 0.5ECU, and the upper limit of the adjustment of the hard wire ECU value is 2.1 ECU. According to the above formula, the larger the cord ECU value is for the container, the larger the upper limit value affecting the ECU is, as shown in FIG. 4. The hard-line ECU value of each container is determined through the formula, so that the available resource of each container on the host machine at any time is ensured to be more than or equal to the soft ECU value, and the service quality of the service operated by each container cannot be influenced by over-allocation.
Second, the single container hardwired ECU value cannot be greater than a preset percentage R of the host's available resources, for example, R may be set to 90%. Reserved resources can be used as buffer resources on one hand, and on the other hand, the host operating system itself occupies a part of resources.
And in a third mode, determining that the sum of the adjusted first resource threshold and the first resource thresholds corresponding to all service containers deployed on the host is not more than K times of the sum of the available resources of the host, wherein K is an integer larger than 1.
In specific implementation, the value of K may be determined according to the service characteristic pressure measurement. For example, K may be set to 2, and if each container on the host uses resources at an off-peak time, that is, the peak usage of each container is no longer at the same time point, the value K may continue to be a larger value, so that the overall resource usage rate of the host may continuously increase, but the service quality of the service running in the container deployed on the host needs to be ensured.
It should be appreciated that, in particular implementations, the upper limit value of the first resource threshold may be determined in combination with at least one of the above three ways.
In the method for adjusting resources based on containers provided in the embodiments of the present invention, two resource thresholds are respectively configured for containers running on a host, where an upper limit of a container resource set by a user is a second resource threshold, but a container resource actually available to the user is a first resource threshold, where the first resource threshold is not less than the second resource threshold, and in a service running process, an actually available resource of each container is dynamically adjusted according to an average load of the host over a period of time, and since an excess resource is a pre-configured resource, it can be ensured that the excess configured resource is used immediately when a container resource demand suddenly rises, thereby achieving fast capacity expansion and reducing service processing delay; on the other hand, because buffer resources do not need to be reserved for each container, each host machine can be mixed with more containers, the utilization rate of the whole host machine is obviously improved, and excess resources are generally used alternately among the containers, so that the whole host machine only needs to reserve a small amount of buffer resources for sharing and using of the containers, the resource waste of the host machine is reduced, and the resource utilization rate of the host machine is improved.
Based on the same inventive concept, the embodiment of the present invention further provides a resource adjusting device based on a container, and because the principle of solving the problem of the device is similar to that of the resource adjusting method based on the container, the implementation of the device can refer to the implementation of the method, and repeated details are not repeated.

Optionally, the resource adjusting unit is specifically configured to decrease the first resource threshold when the average load in the current adjustment period is increased compared with the previous adjustment period, and otherwise, increase the first resource threshold when the average load in the current adjustment period is decreased compared with the previous adjustment period.
