In order to enable those skilled in the art, the container processing side of the understanding being more easier image upgrade of the invention
Method is first below described mirror image in the prior art and container.
Wherein, mirror image is actually to provide the file set of hierarchical file and configuration information, mirror image for container running environment
File realizes the preservation and update of increment by layering, and in some applications, image file can be the program bag of application program
Corresponding associated documents, for example, suffix is the file etc. of .bin .dfi.
Container, is to provide a kind of container technique of light weight virtualization, and the inside of container realizes that details is to be layered existing mirror
As file.Specifically, as shown in Figure 1A, mirror image is the unified visual angle of a pile read only layer, referring to such as Figure 1A, multiple read-only layer heaps
It stacks, in addition to one layer bottom, other layers can all have a pointer to be directed toward next layer, these layers are the realizations inside container
Details (for convenience of description, only shows two layers of image file) in figure, as shown in Figure 1B, container is in all Image Planes
Upper to increase what a writable layers were formed, this writable layers has the process operated on CPU.
In container operation, all operations of image file can finally be embodied in the writable layers of container, the i.e. text of Image Planes
Part is sequence operation from top to bottom, and in addition to nethermost one layer, every layer of reparation can all be embodied on upper layer, and upper layer is repaired
File can cover the file that lower layer is repaired.For example, the file a shown in Figure 1B in A layers of file is needed there are bug
When to be rehabilitated, it can be realized in the B layer file on upper layer by the file a after repairing, thus, in the writable layers of container top layer
Embodiment is that the file a, original file a after image file top layer repairs are capped.To execute when being run on CPU
The corresponding function of file a after reparation, the corresponding function of file a are upgraded.
Certainly, the All Files operation of the image file of this writable layers for being finally embodied in container, in addition to including above-mentioned
The change covering of file is outer, further includes newly-increased and deletion of file etc., file b is not present for A layers shown in Figure 1B for example, working as, on
There is file b in the B layer file of layer, then newly-increased file b is embodied in the writable layers of container top layer, to transport on CPU
When row, the corresponding function of file b is also executed.
For another example, shown in Figure 1B A layers there are file c, there is not file c in the B layer file on upper layer, then to file
The delete operation of c is embodied in the writable layers of container top layer, and file c no longer occur in the writable layers of container top layer, thus in CPU
When upper operation, the corresponding function of file c is no longer executed.
When the upgrading etc. due to application program makes the original image file in container need to update, one is generally required
New mirror image opens a new container, and this image upgrade method takes a long time, with continued reference to above-mentioned example, when needing pair
When original image file is upgraded, such as when original image file A and B are upgraded to D, E and A as shown in Figure 1 C, need
All memories in original container are destroyed, then construct resource in new container, such as will be former by the new container of pull-up again
The data that beginning container is already loaded into memory when running are reloaded, lower so as to cause the upgrading efficiency of image file.
The invention proposes a kind of container upgrading modes of new image file to be passed through according to container internal operation details
It in the operation of the writable layers of container top layer, realizes on the basis of not pull-up new container, realizes that the heat on image file rises
Grade, the internal storage data loaded in original container retains without loading again, substantially increases the upgrading efficiency of image file.
Specifically, Fig. 2 is the flow chart of the container-treatment of image upgrade according to an embodiment of the invention, such as
Shown in Fig. 2, method includes the following steps:
Step 101, the first mirror image before upgrading and after upgrading the second mirror image is obtained.
Step 102, the Mirror Info of the first mirror image and the second mirror image is compared determines the first mirror image relative to second
The deletion layer of mirror image, and/or, increase layer of second mirror image relative to the first mirror image.
Step 103, according to sequence from top to bottom that the file for deleting layer each in the first mirror image and corresponding lower layer is literary
Part is compared, and determines each file change state for deleting layer, and according to each file change state pair for deleting layer and the
The file status of the writable layers of the corresponding the first container of one mirror image synchronizes amendment, and/or,
The file for increasing layer each in the second mirror image is compared with corresponding underlying file according to sequence from top to bottom
Compared with, determine it is each increase layer file change state, and according to it is each increase layer file change state pair and the first mirror image pair
The file status of the writable layers for the first container answered synchronizes amendment.
In an embodiment of the present invention, the first mirror image before upgrading and the second mirror image after upgrading are compared, is determined
The change layer of image upgrade after finding change layer, operates, corresponding with the first mirror image according to the document upgrading of change layer
Be modified in original the first container, thus, realize the first container to container corresponding with the second mirror image update, it is this more
Newly based on original the first container, the new container of pull-up again is not needed, upgrades high-efficient, strong operability.
For the container-treatment of the image upgrade of the more intuitive description embodiment of the present invention, below with reference to specific
Scene is illustrated, and is described as follows:
In this scenario, as shown in figure 4, the file layers that the first mirror image includes are A, B, C, D, E, the first mirror image corresponding the
The writable layer of one container be Z1 layer, the file layers that the second mirror image after upgrading includes be A, B, C, F, G, then according to the first mirror image with
The comparison of the layer file of second mirror image, the first mirror image of discovery are D, E layers relative to the deletion layer of the second mirror image, the second mirror image phase
Increase layer for the first mirror image is F, G layers, thus, the container-treatment of image upgrade through the embodiment of the present invention,
On the basis of the first container, operated according to the document upgrading of change layer, in original the first container corresponding with the first mirror image
It is modified, thus, the update of the first container to container corresponding with the second mirror image is realized, by the way that layer will be write in the first container
It is updated to Z2 for Z1, the container of equally completion image upgrade pulls.It should be noted that the change layer of image upgrade, including the
One mirror image relative to the second mirror image increase layer relative to the first mirror image of deletion layer and the second mirror image, answered in different
It is different with the mode for the change layer under scene, determining image upgrade, it illustrates as follows:
The first example:
In this example, change layer is got by way of successively comparing to the first mirror image and the second mirror image.
As shown in figure 3, above-mentioned steps 101 include:
Step 201, the layer identification of the first mirror image and each layer of the second mirror image is obtained respectively.
Step 202, the layer identification of the first mirror image and each layer of the second mirror image is compared, judges the first mirror image and the second mirror
As whether the layer identification of each layer is identical.
Step 203, if judgement knows that there are different layer identifications between the first mirror image and the second mirror image, according to first
Deletion layer of the mirror image relative to the second mirror image, and/or, increase layer of second mirror image relative to the first mirror image.
Wherein, interlayer identifies each layer of the uniqueness for identifying mirror image, and interlayer mark can be the two of fixed digit
Grade system coding, the interlayers ID such as hexadecimal code, are also possible to that other can realize interlayer differentiation using text or icon etc.
Name identification or icon mark etc..
In the present embodiment, the first image file and each layer identification of the second image file are obtained respectively, by the first mirror image and
The layer identification of each layer of second mirror image compares, and judges whether the layer identification of the first mirror image and each layer of the second mirror image is identical, if
Judgement knows that there are different layer identifications between the first mirror image and the second mirror image, then determine mirror image according to different layer identification
The change layer of upgrading, wherein change layer is identified corresponding to different interlayer, and different interlayer mark includes the first mirror image text
Include in part and do not include (i.e. deletion layer of the first mirror image relative to the second mirror image) in the second image file, alternatively, the first mirror
As file includes and interlayer that the second image file does not include mark (i.e. increase layer of the second mirror image relative to the first mirror image).
Second of example:
In this example, compare between the first mirror image and each layer of the second mirror image comprising file, when existing comprising file not
When identical layer, this layer is determined as to the change layer of image upgrade.
Further, the corresponding document upgrading operation of the change layer of image file, includes original in original image file
Layer deletion and newly-increased new image file new layer addition the two aspect, concentrate below the two aspect
Document upgrading operation, detailed description to according to the document upgrading of change layer operate, to the first container corresponding with the first mirror image
Writable layers synchronize modified implementation process.
On the one hand, according to sequence from top to bottom by the first mirror image it is each delete layer file and corresponding underlying file
It is compared, determines each file change state for deleting layer, and according to each file change state pair and first for deleting layer
The file status of the writable layers of the corresponding the first container of mirror image synchronizes amendment.
It is appreciated that in the present embodiment, the second mirror image deletes some layers of file in the first mirror image, then shows new
The function that application scenarios no longer need original these layer of file to implement, thus, restore these original deleted layer files
Operation, by Such analysis it is found that topmost paper includes update, deletion and the addition of file to the operation of underlying file, thus, it is right
It answers, the operation for restoring original N layers of file is the update recovery of file, addition and deletes.
In one embodiment of the invention, according to sequence from top to bottom by the first mirror image it is each delete layer file
It is compared with corresponding underlying file, knows that the first file present in current deletion layer is also existed simultaneously in correspondence if comparing
Underlying file in, then delete distance is current the first file copy present in the nearest underlying file of layer and arrive the first container
Writable layers.
In this example, deleted if currently deleting the first file present in layer, and this document is in lower layer's text
Exist in part, then no longer needs to delete the operation that layer carries out the first file in the second mirror image after showing upgrading, thus, by the
One file is reduced to delete the first file of the last time before handling in layer.In one embodiment of the invention, according under
The file for deleting layer each in the first mirror image is compared with corresponding underlying file to upper sequence, is known currently if comparing
It deletes the second file present in layer to be not present in corresponding underlying file, then by the second file from the writable layers of the first container
Middle deletion.
In this example, it is deleted if currently deleting the second file present in layer, and this document is in underlying file
It is not present, then no longer needs to delete the corresponding function of the second file in layer in the second mirror image after showing upgrading, thus, directly will
Second file is deleted from the writable layers of the first container.
In one embodiment of the invention, according to sequence from top to bottom by the first mirror image it is each delete layer file
Be compared with corresponding underlying file, if compare know it is current delete the third file being not present in layer be present in it is corresponding under
In layer file, then by the writable layers of the nearest third file copy of the current deletion layer of distance to the first container.
In this example, exist in underlying file if currently deleting the third file being not present in layer, show to rise
Need to delete the corresponding function of third file of deleting in layer in the second mirror image after grade, thus, layer will be deleted most apart from current
Writable layers of the close third file copy to the first container.
The influence for deleting layer to the operation of file is eliminated as a result, will be deleted the underlying file that layer is deleted and is added, will delete layer
The file of addition is deleted, the underlying file etc. before the underlying file for deleting layer covering is reverted to.
For example, as shown in Fig. 5 left figure, the first mirror image include 3 layer by layer file A, B, C deleted as shown in the second mirror image
Except layer is the 3rd layer C layer the in the first mirror image, the file in the 3rd layer in the first mirror image is a, g, and the file in the 2nd layer is a, c,
File in 1st layer is a.By the Documents Comparison in the file and the 2nd layer the 1st layer in the 3rd layer, compare the first file a also simultaneously
It is present in underlying file, then copies the first file a present in the 3rd layer of nearest underlying file of distance to the first container
Writable layers, thus, as shown in Fig. 5 right figure, in updated the first container, eliminate the 3rd layer and the covering of file a operated.
If comparing the second file g present in knowing the 3rd layer to be not present in underlying file, by the second file g from
It is deleted in the writable layers of one container, thus, as shown in Fig. 5 right figure, in updated the first container, the 3rd layer is eliminated to file g
Addition operation.
Know that the third file c being not present in the 3rd layer is present in underlying file if comparing, will exist in underlying file
Third file c copy the writable layers of the first container to.To in updated the first container, eliminate as shown in Fig. 5 right figure
3rd layer of delete operation to file c.
On the other hand, according to sequence from top to bottom that the file for increasing layer each in the second mirror image and corresponding lower layer is literary
Part is compared, and determines each file change state for increasing layer, and according to each file change state pair for increasing layer and the
The file status of the writable layers of the corresponding the first container of one mirror image synchronizes amendment.
In one embodiment of the invention, according to sequence from top to bottom by the second mirror image it is each increase layer file
It is compared with corresponding underlying file, knows that the 4th file present in current increase layer is also existed simultaneously in correspondence if comparing
Underlying file in, then current will increase the 4th file copy present in layer to the first container writable layers.
In this example, if currently increasing the 4th file present in layer, exist in underlying file, then show to upgrade
Need to increase the operation that layer is updated the 4th file in the second mirror image afterwards, thus, will currently it increase by present in layer
Four file copies cover original 4th file to the writable layers of the first container.
In one embodiment of the invention, according to sequence from top to bottom by the second mirror image it is each increase layer file
Be compared with corresponding underlying file, if compare know it is current increase the 5th file present in layer be not present in it is corresponding under
In layer file, then by the writable layers of the 5th file copy to the first container.
In this example, it if currently increasing the 5th file present in layer, is not present in underlying file, then shows to rise
Need to increase the corresponding feature operation of the 5th file in the second mirror image after grade, thus, will currently it increase the 5th present in layer
File copy to the first container writable layers, to increase the corresponding function of the 5th file.
In one embodiment of the invention, according to sequence from top to bottom by the second mirror image it is each increase layer file
Be compared with corresponding underlying file, if compare know it is current increase the 6th file being not present in layer be present in it is corresponding under
In layer file, then the 6th file is deleted from the writable layers of the first container.
In this example, if currently increasing the 6th file being not present in layer, exist in underlying file, then show to rise
Need to delete the corresponding feature operation of the 6th file in the second mirror image after grade, thus, increase by the be not present in layer for current
Six files are deleted from the writable layers of the first container, to delete the corresponding function of the 6th file.
To which the influence for increasing layer to the operation of file be added, the underlying file that layer is deleted will be increased and deleted, layer will be increased
The file of addition adds, and will increase the underlying file that layer updates and covers.
It for example, is the 3rd layer D layers in the second mirror image when increasing layer, wherein the 3rd layer D layers as shown in Fig. 6 left figure
In file be a, h, the file in the 2nd layer is a, c, and the file in the 1st layer is a.By in the 3rd layer file and the 2nd layer the 1st layer
In Documents Comparison, compare the 4th file a and also exist simultaneously in underlying file, then copy the 4th file a to the first container
Writable layers, thus, as shown in Fig. 6 right figure, in updated the first container, increase the 3rd layer D layers and the covering of file a grasped
Make.
If comparing the 5th file h present in knowing the 3rd layer to be not present in underlying file, by the 5th file h from
It copies and enters in the writable layers of one container, thus, as shown in Fig. 6 right figure, in the first container of update, embody newly-increased 3rd layer
The D layers of addition to the 5th file h operates.
Know that the 6th file c being not present in the 3rd layer is present in underlying file if comparing, will exist in underlying file
The 6th file to the first container writable layers delete.To embody the layer of newly-increased D layer in the first container of update
Delete operation of the file to the 6th file c.
In order to more comprehensively illustrate image upgrade of the invention container-treatment implementation process, below with reference to tool
The application scenarios of body are illustrated, wherein and with continued reference to Fig. 4, the layer file being deleted in the first mirror image is E, two layers of D, second
In mirror image increase newly layer file be G, two layers of F.First mirror image is old image, and the second mirror image is new mirror image, in the first container can
Write layer is indicated with Z.
Specifically, first obtaining each layer ID of new old image referring to Fig. 4, each layer ID of new old image is compared, is looked for
Difference section out.For the above figure, difference section is the E of old image, the G of two layers of D and new mirror image, two layers of F.
It eliminates old image and has more the influence for carrying out layer (E, D two layers), specifically: it is started to process from D layers, for being increased newly in D layers
With the file modified, lower layer C is needed, is successively looked in B, A layers, if it is possible to found, illustrate that this document is to be modified
, then need the underlying file that will be found to copy the Z1 layer of old container to；If cannot find, illustrate that this document is to be increased newly
, then it needs to delete this document in the Z1 layer of old container.For deleted file in D layers, it is also desirable to arrive lower layer C, B, A
It is successively looked in layer, the underlying file that will be found then is needed to copy the Z1 layer of old container to after finding.D layers have been handled with this
Afterwards, then successively E layers or higher content are handled in the same way.
New mirror image is synchronized to the Z1 layer of old container compared with the extra layer of old image (G, F two layers), specifically: it is opened from F layers
Beginning processing is copied directly to the Z1 layer of old container for the file for increasing newly and modifying in F layers；For the text deleted in F layers
Part then directly deletes this document in the Z1 layer of old container.After having handled F layers with this, then successively in the same way handle G layers or
Higher content.After the Z1 layer of old container is all written in all differences file as a result, that is, new container is formed, it is writeable in new container
Layer is Z2.
In conclusion the container-treatment of image upgrade of the invention, by the first mirror image before upgrading and after upgrading
