Root is switched to mirror-image system by chroot after record, performs custom script.
Beneficial effects of the present invention are as follows：
1st, cloud platform mirror image preparation method of the invention, meets cloud platform difference mirror image class by creating custom script
Type demand, can be according to the establishment mirror image of the individual demand of different user rapidly and efficiently.
2nd, cloud platform mirror image manufacturing system scalability of the present invention is strong, and cloud platform operation maintenance personnel can be follow-up worked
Cheng Zhong, primary mirror site and the custom script storehouse enriched constantly with sophisticated systems, and existing mirror image is not influenceed in storehouse
And script.
3rd, the method and system that cloud platform mirror image of the present invention makes is versatile, and different cloud platforms can be easily and fast
The carry out integration realization of speed；Additionally by the integrated of cloud platform front end page, it is possible to achieve user oneself is self-defined according to demand
Mirror image is created, improves the experience property of user.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is the module map of present system；
Fig. 2 is the flow chart of the inventive method；
Fig. 3 is another flow chart of the inventive method.
Embodiment
Fig. 1,2,3 are referred to, what it is by a kind of cloud platform mirror image preparation method and system that the embodiment of the present invention provides is
Module map of uniting and method flow diagram.Its each flow specific implementation is described separately below.
It is system centre to control server module, is responsible for the interaction with other four modules, specifically includes：
(1) receive and parse user's making mirroring command and parameter；
(2) downloaded from primary mirror site and be mirrored to mirror nodes；
(3) from custom script storehouse Download Script to mirror nodes；
(4) start and make mirrored procedure in mirror nodes；
(5) mirror image that mirror nodes generate is uploaded into cloud platform mirror site.
Primary mirror image library module is used to deposit the primary image file of cloud platform, can dynamically increase as needed and delete mirror
As file.Custom script library module is used to deposit all script files, can create and delete as needed self-defined pin
This.Mirror nodes module is then that mirror image makes destination and mirror image storage point.Cloud platform mirror image library module is used to deposit cloud platform
Complete image file, virtual machine or container can be created by the image file.
Primary mirror image library module includes being used to deposit the storage medium of mirror image, can be procotol storage or
Local disk stores.Custom script library module includes being used for the storage medium for depositing custom script, can be procotol
Storage or local disk storage.Procotol storage includes HTTP, FTP and ISCSI.
The basic step that the present invention realizes is as follows：
(1) control server downloads designated mirror X to mirror nodes from primary mirror site；
(2) control server from custom script storehouse Download Script to mirror nodes；
(3) primary mirror image X is mapped in mirror nodes and performs Download Script；
(4) mirror image that mirror nodes generate is uploaded to cloud platform mirror site by control server.
Primary mirror image X is mapped in mirror nodes and performs Download Script and is further comprised：
(1) file of a specified size is created in mirror nodes；
(2) file mount is made into block device；
(3) format the block device and change attribute；
(4) block device described in carry is to mirror nodes mount directory；
(5) mirror image X-File is decompressed to the mount directory；
(6) the tandem Run Script of custom script file is pressed；
(7) file is converted into the image file of specified format.
Foregoing block device is the LOOP equipment being mapped to by local file.Specified format include RAW, VHD, QCOW2,
TAR, ACI and DOCKER.
Foregoing custom script includes following characteristic：
(1) script carries out tissue by specific bibliographic structure, front and rear execution sequence between script catalogue be present；
(2) there is the sequencing performed in the script in each catalogue, and it is real that order numeral can be carried by script name
It is existing.
Script catalogue includes that the script storing directory of root need not be switched and needs to switch the script storage of root
Catalogue.
It is specifically described below as follows：
All mirror image native system files are uploaded in primary mirror site deposited in advance by cloud platform operation maintenance personnel.
Here so that local FTP deposits medium as an example, it is assumed that storage has primary image file in FTP：trusty-server-cloudimg-
amd64-root.tar.gz。
All custom script files are uploaded in custom script storehouse deposited in advance by cloud platform operation maintenance personnel.
Here so that local FTP deposits medium as an example, it is assumed that storage has following 2 custom script files in FTP.
Script file 1：install/00-baseline-environment
The content of script is as follows：
This script file has carried out the installation of base and iscsi_package software kits.
Script file 2：install/20-install-init-scripts
Content for script is as follows：
The effect of this script is that the script for wishing starting up has been copied to corresponding position to allow them to play a role.
As above script file name is respectively provided with execution sequence numeral, represents the execution sequence of script respectively, and numeral is smaller
More first carry out, that is, 20-install-init-scripts can be just performed after having performed 00-baseline-environment.
After mirror image, which makes user, sends making virtual machine image order and parameter to control server, server is controlled
Primary image file and the custom script file is downloaded to mirror nodes respective directories, it is as follows：
/root/.cache/image/trusty-server-cloudimg-amd64-root.tar.gz。
/root/.cache/script/install/00-baseline-environment
/root/.cache/script/install/20-install-init-scripts
Start mirror image manufacturing process in mirror nodes, corresponding steps are as follows：
Utilize the file of one specified size of truncate instrument creations：
truncate-s 20G image.raw
File mount is made into block device using losetup instruments：
losetup-f image.raw
Utilize mkfs tool formats block devices：
mkfs-t ext4-L cloudimg-rootfs/dev/loop0
Utilize tune2fs instrument modified block device attributes：
tune2fs/dev/loop0-U${DIB_IMAGE_ROOT_FS_UUID}
Rear mount mirrored disk device file and decompressing downloaded from primary mirror site primary be mirrored to mount directory
In file：
By the script file catalogue carry downloaded in the above-mentioned storehouse from custom script or copy image file equipment to afterwards
In mount directory, and root is switched to mirror-image system by chroot, perform custom script.
Then the image file for having run script is converted into specified format, here exemplified by being appointed as qcow2 forms, tool
Body method is as follows：
qemu-img conVert-O qcow2 image.raw Ubuntu_trusty.qcow2
Finally control server to trigger mirror image after the feedback that image file completes is received and upload cloud platform mirror image
The operation in storehouse.
Embodiments described above is only part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art are not making the obtained scheme of substantive creation, are belonging to the present invention
The scope of protection.
