Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
Referring to fig. 1, a schematic diagram of an information providing method applied to a server of an edge computing cluster according to an embodiment of the present disclosure is shown.
The information providing method applied to the servers of the edge computing cluster provided by the embodiment of the disclosure can be applied to kubernetes (k 8 s) clusters. A unit for performing the method for applying to a server of an edge computing cluster provided by the embodiment of the present disclosure, for example, an information providing apparatus for applying to a server of an edge computing cluster provided by the embodiment of the present disclosure, may be deployed on each node of a k8s cluster. One kubelet is run on each node in the k8s cluster. kubelet are responsible for monitoring containers (containers) on the nodes, managing resources on the nodes.
FIG. 1 shows a container 1, container 2 in a target virtual machine. Both the container 1 and the container 2 are target containers. Fig. 1 shows the pod to which the container 1,2 belongs. The pod is the smallest resource management component in kubernetes and is also the resource object that minimizes running the containerized application. The containers 1 and 2 are kata containers containers. kata containers are container items managed by the OpenStack foundation, but independent of the OpenStack items. kata containers is a runtime tool that can create containers in the form of ultra-lightweight virtual machines using container mirroring. FIG. 1 shows containerd-shim-kata-v2 as daemon. The format of the file corresponding to the target directory is qcow2 (qemu copy-on-write 2). qcow2 file is a block device file provided for qemu. The qcow2 file corresponding to the target directory may be created from containerd-shim-kata-v2. The block granularity based protocol is virtioblk protocol. The virtioblk protocol is a protocol for block devices. The virtioblk protocol is used to transfer data between the virtual machine and the physical machine. The virtioblk protocol supports operations such as reading disk data, writing disk data, querying disk information, disk management, etc. Qemu is started by containerd-shim-kata-v2, and after qemu is started by containerd-shim-kata-v2, qcow2 files corresponding to the target directory are hot-plugged into the target virtual machine by containerd-shim-kata-v2 through virtioblk protocol. After the qcow2 file corresponding to the target directory is hot-plugged into the target virtual machine, the qcow2 file corresponding to the target directory appears as a block device in the target virtual machine. containerd-shim-kata-v2 may send instructions to a container agent in the target virtual machine, KATA AGENT, indicating the mount point in the target virtual machine to mount the target file system directory into container 1, the mount point in container 2, formatting, by KATA AGENT, the corresponding qcow2 file corresponding to the target directory into the target file system directory in the target virtual machine, and by KATA AGENT, the mount point in the target virtual machine to mount the target file system directory into container 1, the mount point in container 2. Thus, both containers 1,2 can perform data reading and data writing to the target file system directory at the block granularity. The data reading and data writing of the container 1 and the container 2 to the target file system directory by the virtioblk protocol may be equivalent to the data reading and data writing to the target directory. Therefore, the target container can read and write data aiming at the target file system directory component at the granularity of blocks, and the reading and writing efficiency related to the directory is improved. Meanwhile, the qcow2 file corresponding to the target directory is related to the copy-on-write data writing mode, the target file system directory obtained by formatting the qcow2 file corresponding to the target directory is also related to the copy-on-write data writing mode, and the storage space is only allocated when the data is written into the target file system directory, so that the storage space can be reduced.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for providing information of a server applied to an edge computing cluster, which may be performed by a computer device such as a server, according to an embodiment of the present disclosure.
In step S201, a file corresponding to a target directory is created, where the target directory is on a host, and a format of the file corresponding to the target directory is related to a copy-on-write data writing manner. That is, the format of the file corresponding to the target directory is a format supporting copy-on-write.
The target directory may be any directory that needs to be provided to a container in the target virtual machine, and the target virtual machine may be any virtual machine that is obtained by virtualizing using resources of the host machine. As an example, the format of the file corresponding to the target directory is qcow2 format, and the qcow2 file corresponding to the target directory may be created.
As one example, the target directory is a temporary storage directory shared by multiple containers in the target virtual machine. The temporary storage directory shared by multiple containers may be referred to as emptydir.
In step S202, the file corresponding to the target directory is hot-plugged into the target virtual machine through the protocol based on the block granularity, where the protocol based on the block granularity is the protocol for the block device.
The block device may be a virtual disk block device. The block granularity based protocol supports data reading and data writing to block devices at block granularity.
As an example, the block granularity based protocol, i.e., the block granularity based protocol, is virtioblk protocol. And hot-inserting (hotplug) the file corresponding to the target directory into the target virtual machine through virtioblk protocol.
After the file corresponding to the target directory is hot-plugged into the target virtual machine, the file corresponding to the target directory appears as a block device in the target virtual machine.
In step S203, the file corresponding to the target directory is formatted into the target file system directory in the target virtual machine, and the target file system directory is mounted to the mounting point in the target container in the target virtual machine.
Wherein the target container performs data reading and data writing to the target file system directory through a protocol based on block granularity. The target file system directory obtained by formatting the file corresponding to the target directory is also related to the copy-on-write data writing manner, that is, the target file system directory supports copy-on-write.
The target virtual machine may be any virtual machine obtained by virtualizing a resource of the host. The target container can be any container in the target virtual machine, which needs to read and write with the target directory. As one example, binding Mount (Bind Mount) may be employed to Mount a target file system directory in a target virtual machine to a Mount point in a target container in the target virtual machine. The target container performing data reading and data writing to the target file system directory via the block granularity based protocol may correspond to the target container performing data reading and data writing to the target directory via the block granularity based protocol. The target container performs data reading and data writing aiming at the target file system catalog through a protocol based on the block granularity, so that the target container can perform data reading and data writing aiming at the target file system catalog at the block granularity, and the reading and writing efficiency related to the catalog is improved.
As an example, the block granularity based protocol is virtioblk protocol, and the file corresponding to the target directory is the qcow2 file corresponding to the target directory. And formatting the corresponding qcow2 file corresponding to the target directory into a target file system directory in the target virtual machine. The target container performs data reading and data writing to the target file system directory via virtioblk protocol.
Referring to fig. 3, fig. 3 is a flowchart illustrating another information providing method applied to a server of an edge computing cluster according to an embodiment of the present disclosure.
In step S301, when the directory information of the target directory includes the configured volume size, a file corresponding to the target directory is created in association with the configured volume size, and when the directory information of the target directory does not include the configured volume size, a file corresponding to the target directory is created in association with the default volume size.
Wherein when the directory information of the target directory includes a configured volume size, the configured volume size may be configured by a user, such as an operation and maintenance engineer.
The data associated with the configured volume size may indicate that the file corresponding to the target directory may store at most the configured volume size. The correlation of the file size corresponding to the target directory and the configured volume is equivalent to limiting the data volume of the data stored in the file corresponding to the target directory, and is equivalent to limiting the data volume of the data stored in the target file system directory obtained by formatting the file corresponding to the target directory.
In the embodiment of the present disclosure, the file corresponding to the target directory may be related to the configured volume size, which considers the case that the data amount of the data used by the pod to which the container belongs in the virtual machine exceeds the defined data amount or the data amount of the data stored by the directory to which the container aims exceeds the defined data amount, and the pod to which the container belongs in the virtual machine is evicted by kubelet. When the directory information of the target directory includes the configured volume size, creating a file corresponding to the target directory and related to the configured volume size, which limits the data volume of the data stored in the target file system directory obtained by formatting the file corresponding to the target directory to be the configured volume size at most, so as to avoid the situation that the data volume of the data used by the pod belonging to the container in the target virtual machine exceeds the limited data volume or the data volume of the data stored in the directory aiming at the container exceeds the limited data volume, and the pod belonging to the container in the target virtual machine is evicted by kubelet. The configured volume size is less than or equal to the defined amount of data.
When the target directory is a temporary storage directory shared by a plurality of containers in the target virtual machine, if the directory information of the temporary storage directory shared by a plurality of containers includes a configured volume size, creating a file corresponding to the temporary storage directory shared by a plurality of containers, which is related to the configured volume size, corresponding to data limiting the volume size that can be configured at most by the file corresponding to the temporary storage directory shared by a plurality of containers in the target virtual machine, corresponding to data limiting the volume size that can be configured at most by the temporary storage directory shared by a plurality of containers in the target virtual machine, and corresponding to data limiting the data amount of data stored in the target file system directory obtained by formatting the file corresponding to the temporary storage directory shared by a plurality of containers. If the directory information of the temporary storage directory shared by the plurality of containers does not include the configured volume size, creating a file corresponding to the temporary storage directory shared by the plurality of containers and related to the default volume size, wherein the file corresponding to the temporary storage directory shared by the plurality of containers in the target virtual machine is limited to store data of the default volume size at most, and the file corresponding to the temporary storage directory shared by the plurality of containers in the target virtual machine is limited to store data of the default volume size at most. As one example, the default volume size is 2G. The default volume size is less than or equal to the defined amount of data.
When the directory information of the target directory includes the configured volume size, the container configuration information is parsed by using a daemon applied to the container in the target virtual machine, for example containerd-shim-kata-v2, to obtain the directory information of the target directory. The configured volume size of the target directory is obtained from the directory information of the target directory. The container configuration information is a config. Json file. The config. Json file is a container profile defined by the OCI (Open Container Initiative) specification. The config. Json file defines all configuration information that the container runtime needs to know and use.
In step S302, the file corresponding to the target directory is hot-plugged into the target virtual machine through the protocol based on the block granularity, where the protocol based on the block granularity is the protocol for the block device.
The block device may specifically be referred to as a virtual disk block device. The block granularity based protocol supports data reading and data writing to block devices at block granularity.
As one example, the block granularity based protocol is virtioblk protocol. And hot-inserting (hotplug) the file corresponding to the target directory into the target virtual machine through virtioblk protocol.
After the file corresponding to the target directory is hot-plugged into the target virtual machine, the file corresponding to the target directory appears as a block device in the target virtual machine.
Step S303, the file corresponding to the target directory is formatted into the target file system directory in the target virtual machine, and the target file system directory is mounted to the mounting point in the target container in the target virtual machine.
Wherein the target container performs data reading and data writing to the target file system directory through a protocol based on block granularity.
As one example, a file corresponding to a target directory is formatted in a target virtual machine as a target file system directory in ext4 format.
Step S303, mounting the target file system directory in the target virtual machine to the mounting point in the target container in the target virtual machine may include: and formatting the file corresponding to the target directory into a target file system directory in the target virtual machine by using a container agent in the target virtual machine. The container agent in the target virtual machine may be KATA AGENT.
In step S303, mounting the target file system directory to the mounting point in the target container in the target virtual machine includes: mounting the target file system directory to a directory corresponding to the identity of the target directory; the catalog corresponding to the identification of the target catalog is mounted to a mounting point in the target container. As one example, the directory corresponding to the identity of the target directory is a directory with a path of/run/kata-containers/< sandbox id >/rootfs/local/< volume name >, where < sandbox id > is the id of the pause container in the Pod to which the target container belongs and < volume name > is the identity of the target directory in the Pod declaration. The target file system directory is mounted to a directory with a path of/run/kata-containers/< sandbox id >/rootfs/local/< volume name >. After mounting the target file system directory to the identified directory corresponding to the target directory, the identified directory corresponding to the target directory may be mounted to a mount point in the target container using a binding mount.
Referring to fig. 4, a schematic diagram of another information providing method applied to a server of an edge computing cluster according to an embodiment of the present disclosure is shown.
The target directory is a temporary storage directory shared by a plurality of containers in the target virtual machine. The temporary storage directory shared by multiple containers in the target virtual machine may be referred to as emptydir.
FIG. 4 shows container 1, container 2 in a target virtual machine. Both the container 1 and the container 2 are target containers. The containers 1 and 2 are kata containers containers. FIG. 4 shows containerd-shim-kata-v2 as daemon. The file corresponding to the target directory has the format qcow2 (qemu Copy-On-Write). The corresponding qcow2 file corresponding to emptydir and corresponding to the configured volume size can be created by containerd-shim-kata-v2, and the corresponding qcow2 file corresponding to emptydir and corresponding to the configured volume size correspond to data limiting the volume size of the corresponding qcow2 file to emptydir and the volume size of the corresponding qcow2 file to be stored at most, correspond to data limiting the volume size of the corresponding emptydir and the volume size of the corresponding target file system to be stored at most. Limiting the volume size data that the qcow2 file corresponding to emptydir can store at most can avoid the situation that the data volume of the data used by the pod of the container in the target virtual machine exceeds the specified size or the data volume of the data stored in the temporary storage directory shared by a plurality of containers exceeds the limited data volume, and the pod of the container in the target virtual machine is evicted by kubelet. The block granularity based protocol is virtioblk protocol. Qemu is started by containerd-shim-kata-v2, and after qemu is started by containerd-shim-kata-v2, qcow2 files corresponding to the target directory are hot-plugged into the target virtual machine by containerd-shim-kata-v2 through virtioblk protocol. After the qcow2 file corresponding to the target directory is hot-plugged into the target virtual machine, the qcow2 file corresponding to the target directory appears as a block device in the target virtual machine. containerd-shim-kata-v2 may send instructions to a container agent KATA AGENT in the target virtual machine that indicate that the target file system directory is mounted to the mount point of container 1 and the mount point of container 2 in the target virtual machine, and format emptydir a corresponding qcow2 file in the target virtual machine by KATA AGENT to obtain the target file system directory. KATA AGENT mount the target file system directory to a directory corresponding to the identity of the target directory. After mounting the target file system directory to the directory mounted to the identification corresponding to the target directory, the target file system directory is mounted to the mount point of container 1, the mount point of container 2, in the target virtual machine by KATA AGENT by KATA AGENT. Thus, both containers 1, 2 can perform data reading and data writing to the target file system directory at the block granularity. The data reading and data writing of the target file system directories by the container 1 and the container 2 through the virtioblk protocol corresponds to the data reading and data writing of the target file system directories by the container 1 and the container 2 through the virtioblk protocol for emptydir. And the reading and writing efficiency related to emptydir is improved.
