Background
The container (container) technology is a technology for packaging and deploying application programs and needed dependencies, class libraries, configuration files, other binary files and the like, and can enable the application programs to run smoothly when the running environments are switched.
After deployment, the container needs to be assigned an IP address to interact with other components. In some schemes, a scheme of dynamically allocating an IP address to a container is adopted, but when the container is created, upgraded and rebuilt, an action of applying the address is executed, and the adoption of a global dynamic IP address allocation mode can cause the change of the IP address of the container after each upgrade or rebuild. Resulting in components that rely heavily on the IP address of the container requiring the IP address to be reconfigured to interact with the container. In addition, because the time of applying for the address is different for each container, IP address areas among different types of containers are mutually alternated, so that the management is inconvenient, the use and maintenance complexity of the containers is improved, and the production efficiency is reduced.

Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
Referring to fig. 1, fig. 1 is a schematic diagram of a data processing apparatus according to the present embodiment, where the data processing apparatus 100 includes a container address allocation device 110, a machine-readable storage medium 120, and a processor 130.
The machine-readable storage medium 120 and the processor 130 are directly or indirectly electrically connected to each other to enable transmission or interaction of data. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The container address assignment means 110 comprise at least one software functional module which may be stored in the machine readable storage medium 120 in the form of software or firmware (firmware) or cured in an Operating System (OS) of the data processing device 100. The processor 130 is configured to execute executable modules stored in the machine-readable storage medium 120, such as software functional modules and computer programs included in the container address assignment device 110.
The machine-readable storage medium 120 may be, but is not limited to, random access Memory (Random Access Memory, RAM), read Only Memory (ROM), programmable Read Only Memory (Programmable Read-Only Memory, PROM), erasable Read Only Memory (Erasable Programmable Read-Only Memory, EPROM), electrically erasable Read Only Memory (Electric Erasable Programmable Read-Only Memory, EEPROM), etc. Wherein the machine-readable storage medium 120 is used to store a program, and the processor 130 executes the program after receiving the execution instruction.
Referring to fig. 2, fig. 2 is a schematic diagram of a method for assigning a container address according to the present embodiment, and each step of the method is explained in detail below.
Step S110, a container address allocation request sent by a container is received, wherein the container address allocation request comprises a container group identifier corresponding to a container group where the container is located.
In this embodiment, when creating a container, a container group identifier of a container group where the container is located may be added to a container parameter, where the container group may be a set of containers having similar functions or commonly implementing a certain function. The container group identification may be an identification capable of representing a unique identity of the container group throughout the operating environment, and the container group identification may be a combination of a plurality of letters and numbers.
In this embodiment, the data processing apparatus 100 may be configured with an address pool service program for performing address pool management, and the address pool service program may provide an address application interface for applying for a container address. The action of sending the container address allocation request when the container is created may be to call the address application interface, and transfer the container group identifier of the container into the container, thereby requesting the address pool service program to obtain the container address.
Taking a kubernetes container cluster management system as an example, the container group identifier can be configured in the animation Annotation information of the Pod unit, and when the container in the Pod unit is created, the container group identifier in the animation Annotation information is acquired and is transmitted to the address pool service program through the address application interface.
Step S120, searching a target address pool corresponding to the container group identifier.
In this embodiment, the data processing apparatus 100 may store address pools corresponding to different container group identifiers in advance. In step S120, the address pool service program searches the address pool corresponding to the container address allocation request as the target address pool according to the container group identifier in the container address allocation request.
And step S130, selecting an available address from the target address pool to be allocated to the container.
In this embodiment, the addresses in the address pool may have different identifications according to their allocation states. For example, when an address is a free address, the address may be identified as an available address. When an address is applied to by a container, but has not yet been formally used by the container, the address may be identified as a preempted address. But an address is applied to by the container and has been formally used by the container, the address may be identified as an assigned address.
The address pool service program may select an address identified as an available address from the target address pool to be allocated to the container sending the container address allocation request after querying the target address pool.
Based on the above design, in the solution provided in this embodiment, the addresses may be allocated to the containers in the corresponding address pools according to the container group identifier in the container address allocation request, so that the addresses allocated to the containers in the same container group are all from the same address pool, so that the addresses in the same container group are relatively fixed, and the address dependent configuration of the containers and the management and maintenance of the container addresses are facilitated.
Optionally, in step S110 of this embodiment, the container address allocation request may further include a unique identifier of the container, where the unique identifier may be an identifier capable of identifying a unique identity of the container in its container group or in the entire deployment environment, such as a universal unique identifier (Universally Unique Identifier, UUID) of the container.
In an example, referring to fig. 3, before step S130, the method for assigning a container address according to the present embodiment may further include step S210.
Step S210, querying whether there is an allocated address corresponding to the unique identifier in the target address pool.
In this embodiment, the address pool may also record a correspondence between an allocated address and a unique identifier of a container that obtains the allocated address. After determining the target address pool, the address pool service program may query the target address pool for the existence of an allocated address corresponding to the unique identifier, i.e., for whether an address has been allocated for the container.
If the assigned address corresponding to the unique identifier is found, step S220 is performed.
If no assigned address corresponding to the unique identifier is found, step S130 is executed, and step S140 is executed after step S130 is executed.
Step S220, allocating the queried allocated address to the container.
In this embodiment, if it is queried that the assigned address corresponding to the unique identifier indicates that the address is assigned to the container in step S210, the container applies for the address again, possibly for reasons such as upgrade or rebuilding, and the same address as used needs to be assigned to the container, the address pool service program assigns the queried assigned address to the container.
If in step S210 no assigned address corresponding to the unique identifier is found, indicating that no address has been assigned to the container, and that the container may be a newly created container, and a new address needs to be assigned to the container, the address pool service program executes step S130 to select an available address from the target address pool to be assigned to the container.
After step S130, step S140 is performed to identify the available address as an allocated address, and the correspondence between the allocated address and the unique identifier of the container is recorded. Thus, if the container is later reapplied for addresses for reasons such as upgrade or rebuild, the used addresses can be allocated to the container according to the unique identifier of the container.
In another example, before step S120, the address pool service program may also directly search for whether there is an allocated address corresponding to the unique identifier in all allocated addresses according to the unique identifier in the container address allocation request.
Alternatively, in this embodiment, the container may send a container address release request to the address pool service program when deleted, the container address release request including an allocated address allocated to the container.
For example, the address pool service program may also provide an address release interface that may be invoked by a container when deleted to pass the address of the container to inform the address pool service program to release the address assigned to the container.
After the address pool service program receives the container address release request, the assigned address can be identified as an available address, and the release time of the available address can be recorded.
In step S130, when the address pool service program selects an available address from the target address pool to be allocated to a container, the address pool service program selects an available address with the latest release time from the available addresses in the target address pool to be allocated to the container.
In other words, in this embodiment, the later the released available addresses are allocated to other containers for use according to the release time of each available address. Therefore, the address Chi Zhongpin frequently changes the address corresponding to the container and keeps the address within a certain range, and the management and maintenance of the container address are convenient.
Alternatively, in the present embodiment, an available address is allocated to the address pool, and the release time of the allocated available address is configured to be 0. For example, when creating an address pool or when the address pool is expanding, the release time of the available address allocated for the address pool is first configured to be 0. Since the addresses of new release time 0 are always assigned to the containers the latest, such that the priority with which these newly assigned addresses of the address pool are assigned to the containers is lowest.
Alternatively, in this embodiment, the address pool service program may periodically detect a release time of each available address in the address pool, and calculate an unused time length of each available address.
If the available addresses reaching the first preset duration threshold when not in use are detected, the total address quantity of the address pool is larger than the address quantity required by the container group corresponding to the address pool, and the address pool service program deletes the available addresses from the address pool.
Optionally, in this embodiment, the data processing apparatus 100 further records the application time of the addresses in each address pool, that is, the time of assigning the available addresses to the address pools.
The address pool service program may detect, according to the application time, an unallocated duration of the available address having a release timestamp of 0.
If the available addresses with unassigned time length reaching the second preset time length threshold are detected, the total address amount of the address pool is larger than the number of addresses required by the container group corresponding to the address pool, and the address pool service program deletes the available addresses from the address pool.
Optionally, in this embodiment, the address pool service program may receive an address pool capacity configuration instruction, and record a target address capacity of the address pool configuration carried in the address pool configuration instruction. For example, the address pool service program may also provide an address capacity configuration interface, by invoking which the target address capacity of each address pool may be configured.
The address pool service program may periodically detect a release time of each available address in the address pool and calculate an unused time period for each available address. If the available addresses reaching the first preset duration threshold value when not in use are detected, and the total number of the addresses in the address pool is larger than the target address capacity of the address pool, indicating that the address pool needs to be contracted, the address pool service program deletes the available addresses from the address pool.
Alternatively, the address pool service program may periodically detect, according to the application time, an unallocated duration of the available address having a release timestamp of 0. If the total number of addresses in the address pool is greater than the target address capacity of the address pool and if the total number of addresses in the address pool is greater than the target address capacity of the address pool, deleting the available address from the address pool.
Therefore, addresses which are not used for a long time in the address pool can be cleaned, so that the long-term occupancy rate of invalid addresses in the pool is reduced, and the overall availability of the addresses is improved.
Optionally, in this embodiment, when the address pool service program allocates an address to the container, the address pool service program may sort the addresses in the target address pool from front to back in the order of the allocated address, the pre-occupied address, the available address with a later release time, and the available address with an earlier release time, and then check whether there is an available address in the address with the earlier sorting in the current target address capacity range of the target address pool.
If so, the available address with the first rank is selected for allocation to the container.
If the address is not present, that is, the address in the current target address capacity range of the target address pool is the allocated address or the pre-occupied address, the capacity of the target address pool is full, and the address can not be continuously allocated, a notification of no available address is returned to the container.
Optionally, in this embodiment, the address pool service program may further provide management interfaces for adding, querying, etc. an address pool, and configuring the address pool managed by the address pool service program through these management interfaces.
