This process is performed during the configuration management phase.
When service management is carried out, the electronic equipment receives a service management instruction carrying a mirror image warehouse address name, wherein the mirror image warehouse address name carried in the service management instruction is called a second mirror image warehouse address name in the embodiment of the invention. The electronic equipment can determine the second service name corresponding to the second mirror image warehouse address name according to the corresponding relation between each first mirror image warehouse address name and each first service name established in the configuration management stage and the received second mirror image warehouse address name. And the electronic equipment performs service management according to the second mirror image warehouse address name and the second service name.

when each application corresponding to the identified first mirror image warehouse address name is deployed, acquiring a third service name of each application; determining a public longest substring of the third service name of each application according to the third service name of each application; and taking the public longest substring as the first service name and storing.
In the embodiment of the invention, for each first mirror image warehouse address name, when the electronic equipment identifies that each application corresponding to the first mirror image warehouse address name is deployed, a third service name of each application is acquired. And then determining the public longest substring of the third service name of each application, wherein the public longest substring of the third service name of each application can be determined through a binary search algorithm, and then the public longest substring is used as a first service name and is stored, so that the first service name corresponding to the first mirror image warehouse address name is accurately determined.
Example 3:
in order to improve the efficiency of acquiring the first service name of the deployed application corresponding to the first mirror repository address name, on the basis of the foregoing embodiments, in the embodiment of the present invention, before acquiring the third service name of each application when each application corresponding to the identified first mirror repository address name is deployed, the method further includes:
judging whether the first service name of the deployment application corresponding to the first mirror image warehouse address name is stored locally or not, if so, obtaining the first service name from the local, and if not, carrying out the follow-up steps.
Aiming at each first mirror image warehouse address name, when the electronic equipment acquires the first service name of the deployment application corresponding to the first mirror image warehouse address name for the first time, acquiring a third service name of each application when each application corresponding to the identified first mirror image warehouse address name is deployed; determining a public longest substring of the third service name of each application according to the third service name of each application; the common longest substring is taken as the first service name and stored locally. When the first service name of the deployment application corresponding to the first mirror image warehouse address name is obtained later, the first service name is directly obtained from the local, and the first service name is not required to be obtained by obtaining the public longest substring.
Therefore, in the embodiment of the present invention, before acquiring, for each first mirror warehouse address name, a first service name of a deployment application corresponding to the first mirror warehouse address name, first determining whether the first service name of the deployment application corresponding to the first mirror warehouse address name is locally stored, if so, acquiring the first service name locally, and if not, acquiring the first service name by acquiring a public longest substring. In the embodiment of the invention, the first service name only needs to be acquired by the mode of acquiring the public longest substring for the first time and is stored locally, and then the first service name can be directly acquired from the local, so that the efficiency of acquiring the first service name of the deployment application corresponding to the first mirror image warehouse address name is improved.

In the embodiment of the invention, after receiving the image deleting instruction, the electronic device acquires each second image file name carried in the image deleting instruction, and deletes the image file of each local second image file name. And judging whether each second image file name carries preset deleting information, if so, forwarding the image deleting instruction to an image storage server to enable the image storage server to delete the image file of each second image file name. By adopting the method provided by the embodiment of the invention, if the mirror image files in the local and mirror image storage servers are required to be deleted at the same time, the preset deleting information is carried in the mirror image deleting instruction, and the deleting instruction is not required to be sent to the mirror image storage server once, so that the mirror image deleting process is simplified.
The cluster management process provided by the embodiment of the invention is described in detail below.
The cluster management related terms are explained first as follows:
the cluster management scheme provided by the embodiment of the invention is realized based on a cluster management tool cluster of a Docker Swarm. Clusterctl relies on a Docker command line tool and a Swarm cluster management tool, and is a simple and easy-to-use Docker cluster management tool.
Dock: the Docker uses Go language introduced by Google company to develop and realize, and packages and isolates the process based on the technologies of cgroup, namespace of Linux kernel, union FS of overlay FS and the like, belonging to the virtualization technology of the operating system layer. Since the isolated process is independent of the host and other isolated processes, it is also called a container. The initial implementation was based on LXC, with LXC removed from version 0.7 onwards, and instead using self-developed libcon tainer, starting from 1.11, and further evolving to use runC and con tainer.
Swarm: dock switch is a built-in (native) cluster management and orchestration tool for dock engines built using a switch kit. Built-in kv memory functions provide a number of new features such as: decentralizing design with fault tolerance, built-in service discovery, load balancing, routing grid, dynamic telescoping, rolling update, secure transmission and the like.
Registry: after the image is built, the image can be easily run on the current host, but if the image needs to be used on other servers, a centralized service for storing and distributing the image is needed, and the service is the Docker Registry.
One Docker Registry may contain multiple repositories (repositories); each warehouse may contain a plurality of tags (tags); each label corresponds to a mirror image. Typically, a repository will contain images of different versions of the same software, and tags are often used for each version of the software. We can specify which version of the image is specifically this software by the format < repository name >: tag >. If no label is given, the label will be the default label.
Taking Ubuntu mirror as an example, ubuntu is the name of the warehouse, which contains different version tags, e.g., 16.04, 18.04, etc. We can specify which version of the image is required by ubuntu:16.04, or ubuntu:18.04.
Warehouse names often appear as two-piece paths, such as jholder/nginx-proxy, the former often meaning the user name in the Docker Registry multi-user environment, and the latter often being the corresponding software name. But this is not absolute, depending on the particular Docker Registry software or service being used.
The technical problems mainly solved by the embodiment of the invention include: docker's own command line is comparatively complicated, and the study degree of difficulty is big, and the fortune dimension personnel is slow. More cases have introduced the Docker switch cluster, with more, longer general operating commands. The Docker self-contained command line tool is a program of a single-threaded model that communicates with Docker daemon via the native Socket using the HTTP API. However, because of the limitation of command lines, we can only pull one mirror image at a time, that is, execute a dock pull command once, and if multiple mirror images are pulled, then the commands need to be executed separately. When deleting images, synchronous deletion of image files on the local and image storage servers cannot be achieved, and the synchronous deletion is generally achieved by respectively sending deletion requests.
In the embodiment of the invention, after the Docker cluster environment is installed and the Swarm cluster is initialized. First, the clusteril command line tool will have an initial use, i.e., automatically collect the required data and store it as a configuration file for other commands. The cluster configuration installation structure diagram is shown in fig. 2, and comprises a management node Master and a plurality of working nodes worker connected with the management node. When the cluster is installed, the registry is installed on the Master node, and all worker nodes including the Master node can operate the registry. Meanwhile, the mirror names in the embodiment of the invention are in the form of domain names for indicating the belongings. The shape is as follows: infosec. Netauth 5000, not directly used IP: a Port. The electronic device in the embodiment of the invention can be a management node or a working node.
Clusterctl specific functions include: configuration self-adaptive initialization, asynchronous batch pulling of images, updating of images, uploading to Registry and synchronous deletion of local/Registry images.
Being a command line tool, the following is expressed separately according to different commands:
1. configuration management-config.
Command (i.e., configuration management instructions): clusterctl config init.
The electronic device automatically generates the following configuration into \etc/clusteril/config.json':
config. Json description:
because the cluster is started, initialization can be performed on the Master node according to the information of the Docker and the cluster, like a Registry address, specific IP can be mapped in system hosts on the devices in the cluster, and all the requests of the infosec. Of course, this value can also be configured by the 'region' tag of the command line, shaped as: clusterctl config init-region haha. Balabala:5000.
SwarmInfo description:
the information stored in SwarmInfo is used later to reduce commands. At initialization, the business application may not have been deployed yet. So the 'StackName' and 'CommonPrefix' may not exist, at which point this portion of information may be automatically captured and stored by the relevant command.
The initialization of the configuration is to collect some common and useful information from the docker and store it in the configuration file. Thus, the operation and maintenance personnel do not need to remember the configurations and can directly inquire. And also serves the following commands.
2. Service management-service.
The commands are simplified by adaptive configuration plus command integration functions.
Prior art service management commands: docker service update- -image info sec. Netauth 5000/test 2netauth-stack_netauth-test.
The service management command of the embodiment of the invention: clusterctl service update Infosec. Netauth 5000/test 2.
netauth-stack _ netauth-test is the service name of the particular service.
When the command is executed, whether the required SwarmInfo exists in the local config. Json, namely CommonPrefix and StackName is judged first, and if not, the name of the service cluster, namely the StackName, is read first. CommonPrefix is obtained by means of the longest substring and stored in config. Json. Fig. 3 is a schematic diagram of a process of acquiring service names of deployment applications corresponding to mirror warehouse address names, first judging whether common prefix and stackmame exist in SwarmInfo in config. Json, if so, directly acquiring service names from local, if not, acquiring Docker stacks-formats { { json } from Docker information, then analyzing the json to acquire the stackmame, comparing all running service names when acquiring common prefix, and then extracting a common longest substring as the service name corresponding to the mirror warehouse address names.
For example, executing the following command will result in the following service name, and finally, which particular service.
From the above results, the longest common substring is obtained by a binary search, and after the completion of the acquisition, the StackName and the common prefix are stored in config. For the next use.
After all parameters are obtained, command lines need to be spliced according to a format preset by cluster management. For example:
in the table, img is the mirror name, config.swarmnfo.CommonPrefix is the common substring read from the configuration, imgName is the resolved mirror name. The mirror image name is infosec.netauth 5000/audio 2.0, the part of the audio and the common substring are acquired and spliced to obtain a service management command line, and service management is carried out according to the service management command line.
3. Mirror image batch pulling.
A command:
| clusterctl image pull-b/tmp/images.conf |
-b/-batch filepath followed by a file containing the mirror name, the file content and format being as follows:
one mirror name per row and the mirror names are all, i.e. to contain the configuration of 'Registry' in the config. Json configuration. This pulls the mirror from the specified registry. After resolving the mirror name in the images. Conf, the Clusterctl main program executes according to the asynchronous commit command of 'docker pull < mirror name >'. Because the command is executed directly, without waiting for the response result, the speed is increased by 2 times. Fig. 4 is a mirror image asynchronous pulling flow chart, when a mirror image pulling instruction is received, each first mirror image file name carried in the mirror image pulling instruction and corresponding identification information of each pulling destination device are obtained. Establishing parallel mirror image pulling processes according to the number of the first mirror image file names; and pulling the image file of each first image file name to the corresponding destination equipment based on the parallel image pulling process and the identification information of each pulling destination equipment.
The Go language, when executing a command line, may return without waiting for the result. The text is described as follows:
4. and synchronously deleting the mirror images.
A command: clusterctl rmi infosecond.netauth 5000/application-management-server 1.0.0- -with-registry.
Synchronous deletion refers to deleting the mirror image with the same name stored locally and then deleting the mirror image on the mirror image storage server registry. First, the deletion operation of registry in the prior art does not provide a command line, but can only operate through HTTP API. After the operation is packaged by the command, the operation and maintenance personnel do not need to know the internal operation mode.
Fig. 5 is a flowchart of image deletion provided in an embodiment of the present invention, when an image deletion instruction is received, each second image file name carried in the image deletion instruction is obtained, and a local image file of each second image file name is deleted.
