Description
Technical Field
The present invention relates to the field of virtualization technologies, and in particular, to a method and an apparatus for deleting an object in a container cluster system, and an electronic device.
Background
In some container clustering systems, such as the K8S (kubemeters) system, multiple objects may need to be created in batches according to actual needs. When one of the objects fails to be created, the object that has been successfully created needs to be deleted to avoid the object that has been successfully created from continuously occupying resources, which is called a rollback mechanism. However, there may be a certain dependency relationship between different objects in the multiple objects, for example, there is a one-to-one correspondence relationship between PV (Persistent Volume) objects and PVC (Persistent Volume class) objects. As another example, a Deployment object may be used to create a pod object. And if the object on which the object depends is not deleted, the object cannot be deleted. For example, if object a is dependent on object b, object a cannot be deleted without object b being deleted.
In the related art, each object that has been successfully created may be polled to determine whether the object can be deleted, and when the object can be deleted, the object is deleted. And the polling is repeated until all objects that have been successfully created are deleted.
However, when the number of objects that have been successfully created is large, polling may take a long time, resulting in inefficient object deletion.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating an object deleting method in a container cluster system according to an embodiment of the present invention, where the method may include:
s101, when object creation fails in the process of creating objects in batch, acquiring the creation sequence of all objects which are successfully created.
The representation form of the creation order may be different according to different application scenarios, and may be represented in the form of an object identification sequence, for example. For example, assuming that objects that have been successfully created are object a, object b, and object c, where object a has an object id of a, object b has an object id of b, object c has an object id of c, and object a is created before object b and object b is created before object c, the obtained creation order may be represented by an object id sequence in the form of { a, b, c }.
The object id is used to uniquely identify the object, that is, the object ids of different objects are different, and the same object id represents the same object. In other possible embodiments, the object identification may also be used to represent the object type of the object.
And S102, deleting all objects which are successfully created in the forward order or the reverse order according to the creation order.
The positive order deletion means that all objects which are successfully created are deleted from front to back according to the creation order. For example, assuming that the creation order is object a → object b → object c, object a may be deleted first, object b may be deleted, and object c may be deleted.
The reverse deletion refers to deleting all objects that have been successfully created from the back to the front in the creation order, for example, if the creation order is object a → object b → object c, then object b, and then object a may be deleted.
Whether the forward deletion or the reverse deletion is adopted can be preset, can be determined according to sequencing parameters input by a user, and can also be firstly adopted for forward deletion (or reverse deletion), and if the forward deletion (or reverse deletion) can not delete the object, the reverse deletion (or forward deletion) is adopted.
It can be understood that in the process of creating objects in batch, the order of creating objects is often determined according to the dependency relationship between the objects, for example, before creating a PVC object, a corresponding PV object needs to be created, the PV object depends on the PVC object, and therefore before deleting the PV object, the PVC object needs to be deleted, that is, the correct deletion order is the reverse order of the creation order. For another example, before a pod object is created, a corresponding deployment object needs to be created, and the deployment object depends on the pod object, so that the pod object needs to be deleted before the deployment object is deleted, that is, the correct deletion order is the positive order of the creation order. Thus, objects may be deleted in the order of creation, in forward order, or in reverse order.
By adopting the embodiment, the object creating sequence is determined according to the dependency relationship among the objects when the objects are created in batch in the container cluster system, and the objects which are successfully created are deleted according to the creating sequence without polling, so that the object deleting efficiency can be improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating an object deleting method when object creation fails in a batch object creating process in a container cluster system according to an embodiment of the present invention, where the method may include:
s201, in the batch creation process, the object identifier of each object successfully created is sequentially stored to obtain an object identifier sequence.
In the process of creating the object in batch, whenever the object is created successfully, the object identifier of the object is saved after all the saved object identifiers in the object identifier sequence.
For example, assuming that object a, object b, and object c are created in sequence, the object identification sequence is initially an empty set. If the object a is successfully created, the object identifier a of the object a is saved in the object identifier sequence, and the object identifier sequence is { a }. If object b is also successfully created, object id b of object b is saved after a in the object id sequence, where the object id sequence is { a, b }. If object c is also successfully created, object id c of object c is saved after a, b in the object id sequence, at which point the object id sequence is { a, b, c }.
S202, when the object is failed to be created in the process of creating the objects in batch, an object identification sequence is obtained.
S203, deleting the object represented by each object identification in the object identification sequence in the forward sequence or the reverse sequence.
For example, assuming that the acquired object identification sequence is { a, b, c }, the positive order deletion refers to sequentially deleting the object a represented by a, deleting the object b represented by b, and deleting the object c represented by c. The reverse deletion means that the object c indicated by c, the object b indicated by b, and the object a indicated by a are deleted in sequence.
The deleting manner of different objects may be different, and in a possible embodiment, for each object identifier, the object represented by the object identifier may be deleted by calling a deleting function corresponding to the object identifier.
By adopting the embodiment, the creation sequence can be accurately and effectively represented by using the object identification sequence.
Referring to fig. 3, fig. 3 is a schematic flow chart of an object deletion method when object creation fails in a process of creating objects in batches in a container cluster system according to an embodiment of the present invention, which may include:
s301, arranging a plurality of objects to be created according to the dependency relationship, and storing the identifier of each object to be created in a preset sequence according to the arrangement sequence to obtain an object sequence to be created.
The objects to be created may be sorted according to an operation instruction input by a user. When sorting, the following should be satisfied: for each object, the object on which the object depends is located before the object, or, for each object, the object on which the object depends is located after the object. Illustratively, it is assumed that the object to be created includes an object a, an object b, and an object c, and that the object a depends on the object b and the object b depends on the object c. The objects to be created may be arranged in the order of { object a, object b, object c } or may be arranged in the order of { object c, object b, object a }.
The preset sequence may be an array or a list. The object identification of an object may be json data of the object and the json data includes at least an object type and a tag of the object.
S302, obtaining the sorting parameters.
The sorting parameter is used for indicating that when the object creation fails in the process of creating the objects in batches, the objects which are created successfully are deleted in the forward or reverse order. Since an object on which an object depends needs to be deleted before deleting the object, if a plurality of objects to be created are arranged in S301, the following are satisfied: for each object, the object on which the object depends is located before the object, then the ordering parameter may indicate positive order. If a plurality of objects to be created are arranged in S301, the following are satisfied: for each object, the object on which the object depends is located after the object, then the ordering parameter may indicate the reverse order.
S303, according to the sequence from first to last, sequentially aiming at each object in the object sequence to be created, calling a creating function corresponding to the object identifier, and creating the object represented by the object identifier.
S304, when the object is successfully created, after all the stored object identifiers in the object identifier sequence, storing the object identifier of the object.
See the relevant description in S201, and will not be described herein.
S305, when the object is failed to be created, acquiring an object identifier sequence, and calling a deleting function corresponding to the object identifier for each object identifier in the object identifier sequence in sequence according to the sequence represented by the sequencing parameter, so as to delete the object represented by the object identifier.
By adopting the embodiment, the objects to be created can be sorted in advance, so that the objects to be created are related to the dependency relationship, and the objects which are successfully created can be deleted correctly through the sorting parameters.
In one possible embodiment, the object that has been successfully created may be deleted after a failure to attempt to create the object. For example, assuming that the object a is an object to be created, a creating function corresponding to the object a may be called to create the object a, and if the object a is not successfully created after the creating function is called, the object that has been successfully created is deleted. However, in some application scenarios, the object creation failure may be caused by some temporary disturbances, such as network fluctuation and random fluctuation of device performance. When the part of the temporary disturbance disappears with time, the object can be created normally, and therefore in this case, if the object that has been created successfully is deleted, a waste of resources may be caused.
In view of this, in one possible embodiment, it may be determined whether the number of times that an object has failed to be created reaches a preset number threshold when the object has failed to be created. And if the preset number threshold value is reached, deleting the object which is successfully created. If the preset number threshold has not been reached, the object is recreated.
By adopting the embodiment, the influence of the temporary disturbance on the object creation can be avoided through multiple attempts in the application scene in which the object cannot be normally created in a short time due to the temporary disturbance, and the resource waste is avoided.
