本申请涉及计算机技术领域，具体而言，涉及一种实现容器运行时数据存储的方法及装置。The present application relates to the field of computer technology, in particular, to a method and device for implementing data storage during container runtime.
背景技术Background technique
在当今云计算迅猛发展的大背景下，虚拟化技术是构建云架构的关键技术之一，保证了云计算平台的高可靠性和高性能，最大化提升云计算平台的硬件资源利用率。容器就是一种轻量级虚拟化技术，通过封装软件的运行环境，实现基于运行平台的虚拟化。虽然容器和传统虚拟化技术相比，具备轻量级，高效，易移植等特点，但每个容器应用单元退出后，对应的运行时环境也相应释放，无法对容器运行期间的数据进行保存。因此，容器需要挂载数据卷来对容器运行期间的数据进行保存，配合容器应用，即实现容器数据持久化。Against the backdrop of the rapid development of cloud computing today, virtualization technology is one of the key technologies for building a cloud architecture, which ensures the high reliability and performance of the cloud computing platform and maximizes the utilization of hardware resources of the cloud computing platform. A container is a lightweight virtualization technology, which realizes virtualization based on the operating platform by encapsulating the operating environment of the software. Although containers are lightweight, efficient, and easy to transplant compared with traditional virtualization technologies, after each container application unit exits, the corresponding runtime environment is also released accordingly, making it impossible to save data during container operation. Therefore, the container needs to mount a data volume to save the data during the running of the container, and cooperate with the container application to achieve container data persistence.
现有技术中，当虚拟机上的容器应用管控模块需要维护大规模容器的编排和管理时，通常需要管理员根据经验预先在虚拟机上定义好大量的数据卷，每个数据卷具有对应的存储空间大小以及存储性能等属性信息；当用户需要运行容器时，获取用户需要使用的数据卷的属性信息，在预先定义的大量数据卷中查找是否存在客户端需要的数据卷，如果存在匹配的数据卷，则将加载容器镜像，运行容器，并将该匹配的数据卷挂载到容器中，实现容器应用的数据持久化。In the prior art, when the container application management and control module on the virtual machine needs to maintain the orchestration and management of large-scale containers, the administrator usually needs to pre-define a large number of data volumes on the virtual machine based on experience, and each data volume has a corresponding Attribute information such as storage space size and storage performance; when the user needs to run the container, obtain the attribute information of the data volume that the user needs to use, and find out whether there is a data volume required by the client in a large number of predefined data volumes. If there is a matching If the data volume is used, the container image will be loaded, the container will be run, and the matching data volume will be mounted to the container to realize the data persistence of the container application.
可见，现有技术需要管理员根据经验提前静态的设置并维护大量的数据卷，当有用户需要运行容器时，通过遍历的方式查找满足用户需求的数据卷。这种方式使得容器运行时数据存储效率低下，且有可能在遍历所有数据卷后，仍然查找不到满足用户需求的数据卷。It can be seen that the existing technology requires the administrator to statically set and maintain a large number of data volumes in advance based on experience. When a user needs to run a container, the data volume that meets the user's needs is searched through traversal. This method makes the data storage inefficient when the container is running, and it is possible that after traversing all the data volumes, it is still impossible to find the data volume that meets the user's needs.
发明内容Contents of the invention
有鉴于此，本申请实施例的目的在于提供一种实现容器运行时数据存储的方法及装置，以提高容器运行时数据存储的效率。In view of this, the purpose of the embodiments of the present application is to provide a method and device for implementing data storage during container runtime, so as to improve the efficiency of data storage during container runtime.
第一方面，本申请实施例提供了一种实现容器运行时数据存储的方法，该方法包括：In the first aspect, the embodiment of the present application provides a method for implementing container runtime data storage, the method including:
获取用户端定义的目标数据卷的属性信息；所述目标数据卷的属性信息包括存储空间大小以及存储性能；Obtain the attribute information of the target data volume defined by the client; the attribute information of the target data volume includes storage space size and storage performance;

将与申请的所述存储空间对应的目标数据卷挂载到待运行容器上。Mount the target data volume corresponding to the requested storage space to the container to be run.
第二方面，本申请实施例提供了一种实现容器运行时数据存储的装置，包括：In the second aspect, the embodiment of the present application provides an apparatus for implementing container runtime data storage, including:
获取模块，用于获取用户端定义的目标数据卷的属性信息；所述目标数据卷的属性信息包括存储空间大小以及存储性能；An acquisition module, configured to acquire the attribute information of the target data volume defined by the client; the attribute information of the target data volume includes storage space size and storage performance;
申请模块，用于从多种存储资源池中查找到满足所述存储性能的存储资源池，并申请一块在该存储资源池中的、与所述存储空间大小对应的存储空间；其中，不同存储资源池对应的存储性能不同；An application module, configured to find a storage resource pool that satisfies the storage performance from various storage resource pools, and apply for a piece of storage space corresponding to the size of the storage space in the storage resource pool; wherein, different storage The storage performance corresponding to the resource pool is different;
挂载模块，用于将与申请的所述存储空间对应的目标数据卷挂载到待运行容器上。The mounting module is configured to mount the target data volume corresponding to the applied storage space to the container to be run.
本申请实施例根据用户端定义的目标数据卷的属性信息，首先从多种存储资源池中查找到满足属性信息中指示的存储性能的存储资源池，并在存储资源池中动态申请一块与所述属性信息中指示的存储空间大小对应的存储空间，然后将与申请的存储空间对应的目标数据卷(也即指示了申请的存储空间位置的数据卷)挂载到待运行容器上。可见，本申请实施例不需要提前静态的设置并维护大量的数据卷，而是当有用户需要运行容器时，直接动态申请相应的数据卷，从而避免了再去遍历查找满足条件的数据卷，也节省了在查找不到满足条件的数据卷时还需要人为干预的成本，提高了容器运行时数据存储的效率。并且，由于无需提前静态的设置并维护大量的数据卷，降低了维护成本，并提高了存储空间的利用率。According to the attribute information of the target data volume defined by the client, the embodiment of the present application first finds a storage resource pool that satisfies the storage performance indicated in the attribute information from various storage resource pools, and dynamically applies for a block in the storage resource pool that is compatible with the storage resource pool. The storage space corresponding to the size of the storage space indicated in the above attribute information, and then mount the target data volume corresponding to the applied storage space (that is, the data volume indicating the location of the applied storage space) to the container to be run. It can be seen that the embodiment of this application does not need to statically set and maintain a large number of data volumes in advance, but directly and dynamically apply for the corresponding data volumes when a user needs to run a container, thereby avoiding traversal to find data volumes that meet the conditions. It also saves the cost of human intervention when the data volume that meets the conditions cannot be found, and improves the efficiency of data storage when the container is running. Moreover, because there is no need to statically set and maintain a large number of data volumes in advance, the maintenance cost is reduced and the utilization rate of storage space is improved.

Obviously, the described embodiments are only It is a part of the embodiments of this application, not all of them. The components of the embodiments of the application generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Accordingly, the following detailed description of the embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.
参见图1所示，本申请一种实施例所提供的实现容器运行时数据存储的方法，可以应用于容器应用运行平台，具体应用于容器应用运行平台中的服务器，包括以下步骤S101～S103：Referring to FIG. 1 , the method for implementing container runtime data storage provided by an embodiment of the present application can be applied to a container application runtime platform, specifically to a server in a container application runtime platform, including the following steps S101-S103:
S101，获取用户端定义的目标数据卷的属性信息；该目标数据卷的属性信息包括存储空间大小以及存储性能。S101. Obtain attribute information of a target data volume defined by a client; the attribute information of the target data volume includes storage space size and storage performance.
这里的目标数据卷可以理解为供容器使用的特殊目录，在本申请实施例中用于表征一块存储空间位置。The target data volume here can be understood as a special directory used by the container, which is used to represent a storage space location in the embodiment of the present application.
在具体实施中，当有容器应用加载到服务器时，服务器会查看容器应用中设置的用户对该容器应用的配置需求，其中包括该容器应用需要的目标数据卷的属性信息，从而确定该容器运行中产生的数据在存储时所需的存储空间大小以及存储性能。In a specific implementation, when a container application is loaded to the server, the server will check the user's configuration requirements for the container application set in the container application, including the attribute information of the target data volume required by the container application, so as to determine that the container is running The storage space size and storage performance required for the data generated in the storage.
这里，存储性能可以分级表示，比如分为快速、中速或者慢速，存储性能的高低一方面与容器应用本身的业务功能相关，比如有些容器应用产生的数据量大，对存储性能的要求较高，有些容器应用产生的数据量小，对存储性能的要求较低。另一方面，存储性能的高低也可以与平台服务费用相关，若用户选择的存储性能较高，则平台收取的服务费用也较高。Here, the storage performance can be expressed in different levels, such as fast, medium or slow. On the one hand, the level of storage performance is related to the business functions of the container application itself. For example, some container applications generate a large amount of data and have higher requirements for storage performance. High, some container applications generate small amounts of data and have low requirements for storage performance. On the other hand, the level of storage performance can also be related to the service fee of the platform. If the storage performance selected by the user is higher, the service fee charged by the platform will also be higher.
S102，从多种存储资源池中查找到满足存储性能的存储资源池，并申请一块在该存储资源池中的、与存储空间大小对应的存储空间；其中，不同存储资源池对应的存储性能不同。S102. Find a storage resource pool satisfying the storage performance from various storage resource pools, and apply for a piece of storage space corresponding to the size of the storage space in the storage resource pool; wherein, different storage resource pools correspond to different storage performances .
这里的存储资源池是指可以进行写入数据以及读取数据的存储空间，可以包括实体的存储设备，比如固态硬盘、磁盘等，也可以包括虚拟化存储资源池，比如云存储平台。The storage resource pool here refers to the storage space where data can be written and read. It can include physical storage devices, such as solid-state drives and disks, and can also include virtualized storage resource pools, such as cloud storage platforms.
在具体实施中，可以根据预先设置的存储资源模板与存储性能之间的映射关系，确定与用户端定义的存储性能对应的存储资源模板；其中，不同的存储资源模板绑定了用于提供存储空间的不同存储资源池；该存储资源模板中定义了能够执行的多种功能的存储接口，当服务器获取到用户端定义的目标数据卷的属性信息后，就会根据目标数据卷的属性信息中记录的存储性能找到对应的存储资源模板，调用该存储资源模板中定义的存储接口执行相关操作。其中，不同功能的存储接口用于被调用后执行不同操作。In a specific implementation, the storage resource template corresponding to the storage performance defined by the client can be determined according to the preset mapping relationship between the storage resource template and the storage performance; wherein, different storage resource templates are bound to provide storage Different storage resource pools for different spaces; the storage resource template defines a storage interface that can perform various functions. When the server obtains the attribute information of the target data volume defined by the client, it will The recorded storage performance finds the corresponding storage resource template, and calls the storage interface defined in the storage resource template to perform related operations. Among them, storage interfaces with different functions are used to perform different operations after being called.
在S102中，存储资源模板中定义的多种功能的存储接口中包括创建数据卷存储接口；通过调用确定的存储资源模板中的所述创建数据卷存储接口，向对应的存储资源池申请目标数据卷。其中，不同存储资源池中的存储设备的存储性能不同。In S102, the multiple functional storage interfaces defined in the storage resource template include creating a data volume storage interface; by calling the created data volume storage interface in the determined storage resource template, apply for the target data from the corresponding storage resource pool roll. Wherein, storage performances of storage devices in different storage resource pools are different.
这里，服务器会预先设置好存储资源模板与存储性能之间的映射关系，当根据用户端定义的目标数据卷的属性信息得到容器运行中产生的数据在存储时所需的存储性能后，会确定与该存储性能对应的存储资源模板。这里的存储资源模板定义了多种功能的存储接口，服务器能够调用相应存储资源模板定义的多种功能的存储接口，在满足存储性能的存储资源池中申请存储空间。Here, the server will pre-set the mapping relationship between the storage resource template and the storage performance. After obtaining the storage performance required for the storage of the data generated during the container operation according to the attribute information of the target data volume defined by the client, it will determine The storage resource template corresponding to the storage capability. The storage resource template here defines storage interfaces with multiple functions, and the server can call the storage interfaces with multiple functions defined by the corresponding storage resource template to apply for storage space in the storage resource pool that meets the storage performance.
表1Table 1
关于存储资源模板定义的多种功能的存储接口的详细描述和说明如上表1所示，包括创建数据卷存储接口、删除数据卷存储接口、挂载数据卷存储接口、返回数据卷的目录路径存储接口以及卸载数据卷存储接口。在上述过程中，通过调用确定的存储资源模板定义的创建数据卷驱动程序，向对应的存储资源池申请存储空间。The detailed description and description of the storage interface for various functions defined by the storage resource template are shown in Table 1 above, including creating a data volume storage interface, deleting a data volume storage interface, mounting a data volume storage interface, and returning the directory path storage of a data volume interface and unmount data volume storage interface. In the above process, apply for storage space from the corresponding storage resource pool by invoking the data volume creation driver program defined by the determined storage resource template.
此外，删除数据卷存储接口是用来向目标存储资源池申请删除已申请的存储空间的存储接口；挂载数据卷存储接口是用来将已申请的存储空间对应的目标数据卷挂载到待运行容器上的存储接口；返回数据卷的目录路径存储接口是用来向用户端发送目标数据卷对应的存储空间的访问路径的存储接口；卸载数据卷存储接口是用来将目标数据卷从运行结束后的容器上进行卸载的存储接口。In addition, the delete data volume storage interface is used to apply to the target storage resource pool for deleting the storage space that has been applied for; the mount data volume storage interface is used to mount the target data volume corresponding to the applied storage space to the waiting The storage interface on the running container; return the directory path of the data volume The storage interface is used to send the access path of the storage space corresponding to the target data volume to the client; the unmounted data volume storage interface is used to remove the target data volume from the running The storage interface for unloading on the finished container.
在一种实施方式中，申请一块在该存储资源池中的、与存储空间大小对应的存储空间，包括：In one embodiment, applying for a piece of storage space corresponding to the size of the storage space in the storage resource pool includes:
在确定用户端具有访问存储资源池的权限后，申请一块在该存储资源池中的、与存储空间大小对应的存储空间。After determining that the user terminal has the right to access the storage resource pool, apply for a piece of storage space corresponding to the size of the storage space in the storage resource pool.
在具体实施中，服务器可以对用户进行分级，比如有的用户为会员用户，有的用户为普通用户，可以设置只有会员用户具有访问存储性能较高的存储资源池的权限。当有容器应用加载到服务器时，根据发起加载请求的用户端对应的用户属性(是否为会员用户)，确定该用户端是否具有访问存储性能较高的存储资源池的权限。In a specific implementation, the server can classify users. For example, some users are member users and some users are ordinary users. It can be set that only member users have access to storage resource pools with high storage performance. When a container application is loaded to the server, determine whether the client has the right to access a storage resource pool with high storage performance according to the user attribute (whether it is a member user) corresponding to the client that initiates the loading request.
S103，将与申请的存储空间对应的目标数据卷挂载到待运行容器上。S103. Mount the target data volume corresponding to the requested storage space to the container to be run.
在具体实施中，服务器在存储资源池中申请了一块与存储空间大小对应的存储空间后，会调用存储资源模板定义的挂载数据卷存储接口，将与该存储空间对应的目标数据卷挂载到待运行容器上，之后该容器在运行时，就能够将运行过程中产生的数据保存在该目标数据卷上。In the specific implementation, after the server applies for a piece of storage space corresponding to the size of the storage space in the storage resource pool, it will call the mount data volume storage interface defined by the storage resource template, and mount the target data volume corresponding to the storage space to the container to be run, and then when the container is running, the data generated during the running process can be saved on the target data volume.
在一种实施方式中，目标数据卷的属性信息还包括容器运行结束后是否销毁目标数据卷的指示信息，这是由用户端提前配置好的，若指示信息指示销毁目标数据卷，即容器运行结束后，用户不想保留保存容器运行过程中产生的数据；而若指示信息指示不销毁目标数据卷，即容器运行结束后，用户想要保留保存容器运行过程中产生的数据，具体如下：In one embodiment, the attribute information of the target data volume also includes indication information indicating whether to destroy the target data volume after the container runs, which is configured in advance by the client. If the indication information indicates that the target data volume is destroyed, the container runs After the end, the user does not want to keep and save the data generated during the running of the container; if the instruction indicates that the target data volume is not destroyed, that is, after the running of the container, the user wants to keep and save the data generated during the running of the container, as follows:
若指示信息指示销毁目标数据卷，则在检测到容器运行结束后，调用删除数据卷存储接口，删除目标数据卷及目标数据卷对应的存储空间中保存的数据。If the instruction information indicates to destroy the target data volume, after detecting that the container has finished running, call the delete data volume storage interface to delete the target data volume and the data stored in the storage space corresponding to the target data volume.
比如，目标数据卷挂载到了容器1上，当容器1运行完毕后，若指示信息指示销毁目标数据卷，通过调用确定的存储接口中的删除数据卷驱动程序，删除目标数据卷及目标数据卷对应的存储空间中保存的数据，即释放掉对应的存储资源池中原来由目标数据卷占用的存储空间。For example, the target data volume is mounted on container 1. After container 1 finishes running, if the instruction indicates to destroy the target data volume, delete the target data volume and the target data volume by calling the delete data volume driver in the determined storage interface The data saved in the corresponding storage space is to release the storage space originally occupied by the target data volume in the corresponding storage resource pool.
若指示信息指示不销毁目标数据卷，则在检测到容器运行结束后，调用卸载数据卷存储接口，将目标数据卷从运行结束后的容器上进行卸载，并保留目标数据卷对应的存储空间中的数据。If the instruction information indicates that the target data volume is not to be destroyed, after detecting that the container has finished running, call the unmount data volume storage interface, unload the target data volume from the container after running, and keep the storage space corresponding to the target data volume The data.
比如，目标数据卷挂载到了容器1上，当容器1运行完毕后，通过调用确定的存储资源模板定义的卸载数据卷存储接口，将目标数据卷从容器1上卸载下来，在对应的存储资源池中并不删除该目标数据卷占用的存储空间，当需要运行与该目标数据卷匹配的容器2时，仍然能够将该目标数据卷挂载到容器2上。For example, the target data volume is mounted on container 1. After container 1 finishes running, the target data volume is unloaded from container 1 by calling the unload data volume storage interface defined by the storage resource template, and the corresponding storage resource The storage space occupied by the target data volume is not deleted in the pool, and the target data volume can still be mounted to the container 2 when it needs to run the container 2 that matches the target data volume.
本申请实施例中，用户可以在容器运行过程中查询运行过程中产生的数据。具体地，在容器运行过程中，若服务器接收到用户端发送的容器运行数据查询请求，通过调用确定的存储资源模板定义的返回数据卷的目录路径存储接口，以向用户端发送目标数据卷对应的存储空间的访问路径，以使得用户端根据访问路径查询容器运行数据。In this embodiment of the application, the user can query the data generated during the running of the container. Specifically, during the running process of the container, if the server receives the container running data query request sent by the client, it will send the target data volume corresponding The access path of the storage space, so that the client can query the container running data according to the access path.
比如，存储性能为快速的存储资源池中包括多个存储设备，如包括存储设备1、存储设备2和存储设备3，当用户想要查看容器运行时产生的数据时，可以向服务器发送容器运行数据查询请求，则服务器会向用户端发送目标数据卷对应的存储空间的访问路径，比如该访问路径可以是一个链接地址，指向存储设备1，则用户可以按照该存储路径在存储设备1中找到该容器运行产生的数据。For example, a storage resource pool with fast storage performance includes multiple storage devices, such as storage device 1, storage device 2, and storage device 3. For data query requests, the server will send the access path of the storage space corresponding to the target data volume to the client. For example, the access path can be a link address pointing to storage device 1, and the user can find it in storage device 1 according to the storage path. The data generated by the container run.
下面列举一个实例来说明本申请方案：An example is listed below to illustrate the application scheme:
用户端提前定义了录音应用所需的目标数据卷的属性信息；该目标数据卷的属性信息包括存储空间大小为30M以及存储性能为快速。The user terminal defines in advance the attribute information of the target data volume required by the recording application; the attribute information of the target data volume includes a storage space size of 30M and a storage performance of fast.
在服务器中预先设置存储资源模板与存储性能之间的映射关系，如图2所示，存储资源模板1定义了存储资源池1，存储资源模板2定义了存储资源池2，存储资源模板3定义了存储资源池3，且这3种存储资源池的存储性能不同，分别为快速、慢速和中速，即存储资源池1中的存储设备的存储性能为快速，存储资源池2中的存储设备的存储性能为慢速，存储资源池3中的存储设备的存储性能为中速。The mapping relationship between storage resource templates and storage performance is preset in the server. As shown in Figure 2, storage resource template 1 defines storage resource pool 1, storage resource template 2 defines storage resource pool 2, and storage resource template 3 defines Storage resource pool 3 is created, and the storage performance of these three storage resource pools is different, namely fast, slow, and medium speed. That is, the storage performance of storage devices in storage resource pool 1 is fast, and the storage performance of storage The storage performance of the device is slow, and the storage performance of the storage devices in the storage resource pool 3 is medium.
如图3所示，当检测到录音容器应用加载到服务器中后，用户端获取到该录音容器应用所需目标数据卷的属性信息，该属性信息包括存储空间大小为30M以及存储性能为快速。当确定用户端具有访问存储资源池1的权限后，会调用存储资源模板1定义的创建数据卷存储接口，在存储资源池1中申请一块30M的存储空间，该存储空间就作为录音容器应用运行产生的数据的存储位置。当申请了该30M的存储空间后，会将与该30M的存储空间对应的目标数据卷挂载到待运行录音容器上，即实现了录音容器应用的数据持久化。As shown in Figure 3, after detecting that the recording container application is loaded into the server, the client obtains the attribute information of the target data volume required by the recording container application, the attribute information includes the storage space size is 30M and the storage performance is fast. When it is determined that the client has access to the storage resource pool 1, it will call the creation data volume storage interface defined by the storage resource template 1, and apply for a 30M storage space in the storage resource pool 1, and the storage space will be run as a recording container application The storage location of the generated data. After applying for the 30M storage space, the target data volume corresponding to the 30M storage space will be mounted on the recording container to be run, which realizes the data persistence of the recording container application.
当检测到该录音容器应用运行结束后，通过查看目标数据卷的属性信息中包括的容器运行结束后是否销毁目标数据卷的指示信息，发现该指示信息指示销毁目标数据卷，则调用存储资源模板1定义的删除数据卷存储接口，删除目标数据卷及目标数据卷对应的存储空间中保存的数据。When it is detected that the recording container application has finished running, check whether the target data volume is destroyed after the container is completed in the attribute information of the target data volume. If the indication information indicates that the target data volume is destroyed, the storage resource template is invoked. 1. The defined delete data volume storage interface deletes the target data volume and the data stored in the storage space corresponding to the target data volume.

可选地，目标数据卷的属性信息还包括容器运行结束后是否销毁目标数据卷的指示信息；多种功能的存储接口中还包括删除数据卷存储接口和卸载数据卷存储接口；如图5所示，容器运行时实现数据存储的装置400还包括：Optionally, the attribute information of the target data volume also includes indication information on whether to destroy the target data volume after the container finishes running; the multiple-function storage interface also includes a delete data volume storage interface and an unmount data volume storage interface; as shown in Figure 5 As shown, the device 400 for implementing data storage when the container runs also includes:
