Description

Container resource quota regulation and control method and system for vehicle-mounted system Technical Field The invention relates to the technical field of vehicle-mounted operating systems, in particular to a method and a system for regulating and controlling container resource quota of a vehicle-mounted system. Background The container is a lightweight, portable, self-contained software packaging technology that allows applications to run in the same manner almost anywhere. Unlike conventional virtualization techniques, the container runs in some user space of the operating system, isolated from other processes of the operating system, and is much smaller in volume than a virtual machine. The whole operating system does not need to be started, so that the container is faster in deployment and starting speed, lower in cost and easier to migrate. Currently mainstream container technologies, such as dock, are typically implemented based on the characteristics of the Linux operating system kernel (e.g., namespace, control group cgroup, etc.), which cannot be directly migrated to other operating systems without these characteristics. However, linux operating systems have limitations that are not well-defined in the four seas. For example, in the fields of industrial robots, autopilot, etc., some operating systems with strong real-time are more suitable. To combine the advantages of both, the operating system kernel needs to be modified to have similar namespace and control group characteristics to implement container functionality. Important functions of Linux container technology are resource isolation and resource limitation. The resource limiting function is realized by means of a control group function in the Linux kernel. And the resource isolation is realized by means of a naming space function in the Linux kernel. To implement migration of resource isolation functions in container technology, one of the links is to implement a namespace-like technique to perform isolated system calls. Existing Linux container technology typically performs resource isolation of control groups in the following manner: Directly mapping a controller mounting point of a control group of a host into a container, wherein the controller can be a processor time slice controller, a processor core binding controller, a memory controller and a disk read-write bandwidth controller; the processes in the container can directly access and operate the control group hierarchy of the host; the control group is dependent on the namespace for basic isolation, but the isolation effect is limited in the control group environment. However, in the on-vehicle Android container scenario, the following problems exist in the prior art: the resource escape risk is that the process of the Android system in the container can escape out of the resource control range of the host machine by writing the host machine control group, so that the resource limitation is invalid; Static resource allocation, wherein the traditional scheme adopts fixed resource quota and cannot be dynamically adjusted according to driving scenes; and the compatibility problem is that if the path of the Android control group in the container is modified, a large amount of adaptation work is needed, and the stability of the system is affected. Disclosure of Invention The invention provides a container resource quota regulating method and system of a vehicle-mounted system, and aims to realize optimal balance of safety and experience while avoiding resource escape risks. In order to achieve the above object, the present invention provides a method for regulating and controlling container resource quota of a vehicle-mounted system, which is applied to a vehicle-mounted Android system, and comprises: Step 1, creating container sub-groups for a resource controller of a vehicle-mounted Android system in a vehicle-mounted Android system starting stage, and setting initial resource quota for each container sub-group to serve as a resource isolation boundary of a container; step 2, mapping all the container sub-groups to the root catalogs of the corresponding resource controllers in the containers according to the resource isolation boundaries; Step 3, monitoring the gear of the target vehicle through a resource management daemon of the vehicle-mounted Android system to obtain a gear state; And step 4, adjusting quota parameters and competition weight parameters of each resource controller according to the gear state and the state of the container to obtain a container resource quota regulation result. Further, the resource controller of the vehicle-mounted Android system includes: processor time slice controller, processor core binding controller, memory controller, disk read-write bandwidth controller. Further, creating a container sub-group for a resource controller of the vehicle-mounted Android system includes: Creating a container root group under each resource controller root direc
