In image file then start container such as using the mount directory of disk as container root, so that container be made to run the magnetic
Image file in disk, to save local disk space.
Referring to shown in Fig. 3 B, for the flow chart of image file acquisition methods, this method may include:
Step 301, first server obtains image file A, determines the disk size that image file A is occupied.
For example, first server can receive the image file A of developer's input, image file A may include mirror image
The disk size (subsequent to be illustrated by taking disk size 1 as an example, for example, disk size 1 can be 3G) that file A is occupied.Certainly,
Image file A can also include other contents, without limitation.
Step 302, first server sends the creation message for carrying disk size 1 to storage equipment.
Step 303, storage equipment is localling create corresponding with disk size 1 first after receiving the creation message
Disk, it is subsequent that first disk is known as disk A, and the size of disk A is disk size 1.
Step 304, disk A is mounted to first server by first server.For example, first server creation is directed to mirror image
The catalogue of file A, and disk A is mounted under the catalogue of first server.
Wherein, disk A is mounted to first server to refer to, the disk A of long-range storage equipment is mounted to the first clothes
Business device directly uses, and the operation to disk A is exactly the operation directly to long-range storage equipment.
Step 305, image file A is written to disk A by first server.For example, first server is to writing under the catalogue
When entering image file A, in fact, being that image file A is written to disk A.
Wherein, image file A is written to the process of disk A by first server, actually directly writes image file A
Enter the disk A to storage equipment, the disk without being written to first server local.
Step 306, the disk A stored in equipment is converted to snapshot A by first server.
Wherein, after image file A is written to disk A by first server, if image file A write-in is completed, storage is set
Complete image file A is just written in standby disk A.In view of disk A is a read-write disk, therefore, in order to keep away
Exempt to modify to the image file A in disk A, disk A can be converted to snapshot A (such as first server to storage equipment
The conversion command for being directed to disk A is sent, disk A is converted into snapshot A by storage equipment, with no restrictions to this conversion process), it should
The content of snapshot A is identical as the content of disk A, i.e. snapshot A also includes complete image file A.Moreover, snapshot A is one
Readable not writeable snapshot can not modify to the image file A in snapshot A.Moreover, it is also possible to use this snapshot A
Disk identical with disk A is cloned, subsequent embodiment introduces the cloning procedure.
Step 307, first server determines the description information of disk A, wherein the description information can include but is not limited to
The description information of disk A corresponding snapshot (such as snapshot A) in storage equipment.
For example, after disk A is converted to snapshot A by storage equipment, it can be by description information (such as name of snapshot A of snapshot A
Title, creation time etc., without limitation) it is sent to first server, first server can receive the description letter of snapshot A
Breath, description information, that is, disk A description information of snapshot A.
Step 308, first server by the Mirror Info of the description information of disk A and image file A (such as mirror image title,
It is image parameter etc., without limitation) corresponding relationship store into storage server.
Wherein, image file A can also include the Mirror Info of image file A, and first server can be from image file A
In get the Mirror Info, and the description information of disk A and the Mirror Info are sent to storage server, so that storage takes
The description information of device storage disk A of being engaged in and the corresponding relationship of the Mirror Info.
Step 309, the Mirror Info of image file A is sent to second server by first server.
It is, of course, also possible to the Mirror Info of image file A is sent to second server using other way, for example, opening
The Mirror Info of image file A is sent to second server by originator, without limitation.
Step 310, second server obtains the corresponding Mirror Info of image file A.
Step 311, second server inquires description information corresponding with the Mirror Info from storage server.Its
In, due to being stored with the corresponding relationship of the Mirror Info of image file A and the description information of disk A in storage server,
Second server can inquire and the Mirror Info after the Mirror Info for getting image file A from storage server
Corresponding description information, the i.e. description information of disk A.
Step 312, second server sends the clone's message for carrying the description information of disk A to storage equipment.
Step 313, storage equipment inquires and the description information of disk A (such as snapshot A after receiving clone's message
Title, creation time etc.) corresponding snapshot A, and snapshot A is cloned and (to the process that snapshot A is cloned, is equivalent to
Disk A is cloned), the disk B after being cloned.
Wherein, since snapshot A includes image file A, disk B also includes image file A.
Step 314, disk B is mounted to second server by second server.For example, second server can create disk
The mount directory of B, and disk B is mounted under the mount directory of second server.
Step 315, the image file A in second server operation disk B.For example, can using above-mentioned mount directory as
Container root, then starts container, to make the image file A in container operation disk B.
Wherein, the process of the image file A in second server operation disk B, actually directly operation stores equipment
Disk B in image file A, rather than use second server local disk.
Wherein, the second server where each container can use above-mentioned steps 310- step 315, to run storage
Image file A in the disk of equipment then provides a user service corresponding with image file A.
Referring to shown in Fig. 3 C, for another flow chart of image file acquisition methods, this method may include:
Step 321, first server obtains image file B, and determines the disk size that image file B is occupied, and determine
With the Mirror Info of the associated image file of image file B.For example, then should when image file A is associated with image file B
Mirror Info may include the Mirror Info of image file A.
Wherein, image file A is associated with image file B and refers to: the function in order to realize image file B is then needed in mirror
As realizing on the basis of file A, i.e., image file B can be multiplexed the content of image file A.
For example, first server can receive the image file B of developer's input, image file B may include and mirror
As the Mirror Info of the associated image file A of file B.In addition, image file B may include image file B occupy disk it is big
It is small (subsequent to be illustrated by taking disk size 2 as an example, for example, disk size 2 can be 4G).Certainly, image file B can also be wrapped
Other contents are included, it is without limitation.
Step 322, first server inquires description information corresponding with the Mirror Info from storage server.Its
In, due to being stored with the corresponding relationship of the Mirror Info of image file A and the description information of disk A in storage server,
First server can also inquire from storage server and believe with the mirror image after the Mirror Info for getting image file A
Cease corresponding description information, the i.e. description information of disk A.
Step 323, first server sends creation message to storage equipment, wherein the creation message can carry disk
The description information description information of snapshot A (such as disk A corresponding) of size 2 and disk A.
Step 324, storage equipment is localling create disk corresponding with disk size 2 after receiving the creation message
C, the i.e. size of disk C are disk size 2.Moreover, first inquiring the description information with disk A when storage equipment creation disk C
(title, creation time of such as snapshot A) corresponding snapshot A, and (the mistake cloned to snapshot A is cloned to snapshot A
Journey is equivalent to and clones to disk A), the disk D after being cloned, then, storage equipment are created on the basis of disk D
Disk C, that is to say, that may include the image file A in snapshot A in disk D, and include image file A in disk C.
Step 325, disk C is mounted to first server by first server.For example, first server creation is directed to mirror image
The catalogue of file B, and disk C is mounted under the catalogue of first server.
Step 326, image file B is written to disk C by first server.For example, first server is to writing under the catalogue
When entering image file B, in fact, being that image file B is written to disk C.
Wherein, image file B is written to the process of disk C by first server, actually directly writes image file B
Enter the disk C to storage equipment, the disk without being written to first server local.Moreover, image file B is written to magnetic
After disk C, disk C may include image file A and image file B.
Step 327, the disk C stored in equipment is converted to snapshot C by first server.
Wherein, after image file B is written to disk C by first server, if image file B write-in is completed, storage is set
Image file A and image file B are just written in standby disk C.In view of disk C is therefore a read-write disk is
Avoid in disk C image file A and image file B modify, disk C can be converted to snapshot C, snapshot C
Content it is identical as the content of disk C, i.e., snapshot C also may include image file A and image file B.Moreover, snapshot C is
One readable not writeable snapshot, i.e., can not in snapshot C image file A and image file B modify.Moreover, may be used also
To use this snapshot C to clone disk identical with disk C, subsequent embodiment introduces the cloning procedure.
Step 328, first server determines the description information of disk C, wherein the description information can include but is not limited to
The description information of disk C corresponding snapshot (such as snapshot C) in storage equipment.
For example, after disk C is converted to snapshot C by storage equipment, it can be by description information (such as name of snapshot C of snapshot C
Title, creation time etc., without limitation) it is sent to first server, first server can receive the description letter of snapshot C
Breath, the description information of snapshot C i.e. the description information of disk C.
Step 329, first server by the Mirror Info of the description information of disk C and image file B (such as mirror image title,
It is image parameter etc., without limitation) corresponding relationship store into storage server.
Wherein, image file B can also include the Mirror Info of image file B, and first server can be from image file B
In get the Mirror Info, and the description information of disk C and the Mirror Info are sent to storage server, so that storage takes
The description information of device storage disk C of being engaged in and the corresponding relationship of the Mirror Info.
Step 330, the Mirror Info of image file B is sent to second server by first server.
It is, of course, also possible to the Mirror Info of image file B is sent to second server using other way, for example, opening
The Mirror Info of image file B is sent to second server by originator, without limitation.
