The cluster management method provided by the embodiment of the invention is applied to electronic equipment, and the electronic equipment can be equipment such as a PC (personal computer), a tablet personal computer and the like, and can also be a server.
After receiving the configuration management instruction, the electronic device acquires each first mirror image warehouse address name in the cluster, then acquires a first service name of the deployment application corresponding to each first mirror image warehouse address name, and establishes a corresponding relationship between each first mirror image warehouse address name and each first service name. This process is performed during the configuration management phase.
When service management is performed, the electronic device receives a service management instruction carrying an address name of a mirror image warehouse, wherein the address name of the mirror image warehouse carried in the service management instruction is called as a second mirror image warehouse address name in the embodiment of the invention. The electronic device can determine a 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.
In the embodiment of the present invention, after receiving the configuration management instruction, the electronic device obtains, for each first mirror image repository address name in the cluster, a first service name of the deployment application corresponding to the first mirror image repository address name, and establishes a correspondence between each first mirror image repository address name and each first service name. And then when sending a service management instruction to the electronic equipment, the electronic equipment determines a corresponding second service name according to the second mirror image warehouse address name only by carrying the second mirror image warehouse address name, and then service management is completed. Because the specific service name does not need to be carried in the service management instruction, the electronic equipment determines the corresponding service name according to the mirror image warehouse address name, the problem of complicated and long operation commands is solved, and the learning cost of operation and maintenance personnel is reduced.

In the embodiment of the invention, for each first mirror image warehouse address name, when the electronic device identifies that each application corresponding to the first mirror image warehouse address name is deployed, the third service name of each application is obtained. And then determining a common longest substring of the third service name of each application, wherein the common longest substring of the third service name of each application can be determined through a binary search algorithm, and then the common longest substring is used as the 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 efficiency of obtaining a first service name of a deployment application corresponding to a first mirror repository address name, on the basis of the foregoing embodiments, in an embodiment of the present invention, when each identified application corresponding to the first mirror repository address name is deployed, before obtaining a third service name of each identified application, the method further includes:
and judging whether a first service name of the deployment application corresponding to the address name of the first mirror image warehouse is stored locally, if so, acquiring the first service name from the local, and if not, performing the subsequent steps.
For each first mirror image warehouse address name, when the electronic equipment acquires a first service name of a deployment application corresponding to the first mirror image warehouse address name for the first time, and when each application corresponding to the first mirror image warehouse address name is already deployed, acquiring a third service name of each application; determining a common longest substring of the third service name of each application according to the third service name of each application; and taking the common longest substring as a first service name and storing the common longest substring locally. And when the first service name of the deployment application corresponding to the address name of the first mirror image warehouse is obtained subsequently, the first service name can be directly obtained from the local place without obtaining the first service name in a mode of obtaining the public longest substring.
Therefore, in the embodiment of the present invention, before acquiring, for each first mirror image warehouse address name, a first service name of a deployment application corresponding to the first mirror image warehouse address name, the electronic device first determines whether the first service name of the deployment application corresponding to the first mirror image warehouse address name is locally stored, if so, acquires the first service name from the local, and if not, acquires the first service name by acquiring a longest common substring. In the embodiment of the invention, the first service name is acquired only for the first time in a mode of acquiring the public longest substring and is stored locally, and then the first service name can be directly acquired locally, so that the efficiency of acquiring the first service name of the deployment application corresponding to the address name of the first mirror image warehouse is improved.

and splicing the address name of the second mirror image warehouse and the second service name according to a preset format of cluster management, determining a service management command line, and performing service management according to the service management command line.
In the embodiment of the invention, after the electronic device determines the second mirror image warehouse address name and the second service name, the second mirror image warehouse address name and the second service name need to be spliced according to a preset format of cluster management, the service management command line is determined, and after the command line in the preset format is obtained, the electronic device performs service management according to the service management command line.

The electronic equipment receives the mirror image pulling instruction, wherein the mirror image pulling instruction can carry one mirror image file name to be pulled or a plurality of mirror image file names to be pulled, and the number is not limited in the embodiment of the invention. In addition, the mirror image pulling instruction carries identification information of each pulling destination device corresponding to each mirror image file name. The electronic device can obtain each first image file name carried in the image pulling instruction and corresponding equipment identification information of each pulling destination.
The electronic equipment establishes parallel mirror image pulling processes according to the number of the first mirror image file names, namely the number of the mirror image pulling processes is the same as that of the first mirror image file names, and one first mirror image file is pulled through one process. The electronic equipment pulls the image file of each first image file name to the corresponding target equipment based on the parallel image pulling process and the identification information of each pulling target equipment, so that batch pulling of the image files is realized.

and judging whether each second image file name carries preset deleting information, if so, forwarding the image deleting instruction to an image storage server, and enabling the image storage server to delete the image file of each second image file name.
In the embodiment of the invention, after receiving the mirror image deleting instruction, the electronic device acquires each second mirror image file name carried in the mirror image deleting instruction, and deletes the mirror image file of each second mirror image file name locally. And judging whether each second image file name carries preset deleting information, if so, forwarding the image deleting instruction to an image storage server, so that the image storage server deletes the image file of each second image file name. By adopting the method provided by the embodiment of the invention, if the image files in the local storage server and the image storage server are required to be deleted at the same time, only the preset deleting information is carried in the image deleting instruction, and the deleting instruction is not required to be sent to the image storage server independently, so that the image deleting process is simplified.
The cluster management process provided by the embodiment of the invention is explained in detail below.
First, the cluster management related terms are explained as follows:
the cluster management scheme provided by the embodiment of the invention is realized based on a cluster management tool clusterictl of a Docker Swarm. The Cluster 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.
Docker: docker uses Go language that Google company promoted to develop and realize, because technology such as cgroup, namespace of Linux kernel, Union FS of the overlayFS class, etc., encapsulate and isolate the process, belong to the virtualization technology of the operating system level. An isolated process is also referred to as a container because it is independent of the host and other isolated processes. The initial implementation was based on LXC, removing LXC from version 0.7 onwards, and instead using self-developed libcontaner, starting from 1.11, further evolving to use runC and contianerd.
Swarm: docker Swarm is a cluster management and orchestration tool built-in (native) to the Docker engine using the SwarmKit. The built-in kv storage function provides a number of new features, such as: decentralized design with fault tolerance, built-in service discovery, load balancing, routing grids, dynamic scaling, rolling update, secure transmission and the like.
Registration: after the image is built, the image can be easily operated 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 Docker Registry is the service.
A Docker Registry may contain multiple warehouses (repositories); each warehouse may contain a plurality of tags (tags); one mirror image for each label. Typically, a repository will contain images of different versions of the same software, and tags are used to correspond to the various versions of the software. We can specify which version of this software is the mirror image specifically by the format of < repository name > < tag >. If no tag is given, latest will be the default tag.
Taking the Ubuntu image as an example, Ubuntu is the name of the warehouse, which contains various version tags, such as 16.04, 18.04, etc. We can specify which version of the mirror is required by either ubuntu:16.04 or ubuntu: 18.04.
Warehouse names often appear as two-part paths, such as jwilder/nginx-proxy, the former often meaning the user name in a Docker Registry multi-user environment, and the latter often the corresponding software name. But this is not absolute and depends on the software or service of the particular Docker Registry used.
The technical problems mainly solved by the embodiment of the invention comprise: docker's own command line is comparatively complicated, and the study degree of difficulty is big, and the fortune dimension personnel are on hand slow. What is more, a Docker Swarm cluster is introduced, and the general operation command is more and longer. The command line tool of the Docker is a program of a single thread model, and communicates with the Docker daemon through a local Socket by using an HTTP API. However, because of the limitation of the command line, we can only pull one mirror at a time, i.e. execute the docker pull command once, and if multiple mirrors are pulled, the commands need to be executed separately. When the mirror image is deleted, the mirror image files on the local storage server and the mirror image storage server cannot be synchronously deleted, and the deletion is generally realized 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 clusterctl command line tool has an initialization for the first use, that is, the required data is automatically collected and stored as a configuration file for use by other commands. The cluster configuration installation structure diagram is shown in fig. 2 and includes a management node Master and a plurality of worker nodes worker connected to 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 all in a domain name form in order to indicate the mirror names belong to. The shape is as follows: netauth:5000, IP not directly used: port. The electronic device in the embodiment of the present invention may be a management node or a work node.
The specific functions of Clusterctl include: configuration self-adaptive initialization, asynchronous batch mirror image pulling, mirror image updating and uploading to Registry and local/Registry mirror image synchronous deletion.
Because of the command line tool, the following is expressed separately according to different commands:
1. configuration management-config.
Command (i.e. configuration management instruction): clusterctl config init.
The electronic device will automatically generate the following configuration into '/etc/clusterictl/config.json':
json states:
because the cluster is started, configuration initialization can be performed on the Master node according to the information of the cluster and the Docker, and a specific IP is mapped in a system hosts on the cluster equipment like a Registry address, and all requests of info sec. Of course, this value can also be configured via the "- -gisty" tag of the command line, which is shaped as: balaubala: 5000.
SwarmInfo states:
the information stored in SwarmInfo is used later to condense the command. At initialization, the business application may not have been deployed. So the 'StackName' and 'CommonPrefix' may not exist, and this part of information can be automatically captured and stored by the related command.
The initialization of the configuration is to collect some common and useful information from the docker and store the information in the configuration file. Therefore, the operation and maintenance personnel do not need to remember the configurations and can directly inquire. While also serving subsequent commands.
2. Service management-service.
The command is simplified by adding a command integration function to the adaptive configuration.
Service management command of the prior art: netauth:5000/test:2netauth-stack _ netauth-test.
The service management command of the embodiment of the invention comprises the following steps: clusterctl service update info sec. netauth:5000/test: 2.
netauth-stack _ netauth-test is the service name of a specific service.
First, when executing the command, it is determined whether there is any required SwarmInfo in local config. The commonpiffix is obtained by means of the longest substring and stored in config. Fig. 3 is a schematic diagram of a process of obtaining a service name of a deployment application corresponding to a mirror repository address name, and first of all, it is determined whether commonpiffix and StackName exist in SwarmInfo in a docker.json, if so, the service name is directly obtained from the local, if not, a Docker stack ls-format { { json. } is obtained from Docker information, then the json is analyzed to obtain the StackName, all running service names need to be compared when obtaining the commonpiffix, and then a common longest substring is extracted as the service name corresponding to the mirror repository address name.
For example, executing the following command, the following service name will be obtained, which is the specific one that is served last.
And acquiring the longest common substring through binary search from the result, and storing the StackName and CommonPrefix in config. For the next use.
After all the parameters are acquired, the command lines need to be spliced according to a preset format of cluster management. For example:
in the table, img is a mirror name, config, swarminfo, commonpiffix is a common substring read from configuration, and imgName is a resolved mirror name. And the mirror image name is info sec. netauth: 5000/audio: 2.0, the part of the audio and the public substring are obtained 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 pull.
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 'Registry' configuration in the config. So that the mirror can be pulled from the specified registry. After resolving the mirror name in images.conf, the Clusterctl main program asynchronously submits a command to execute according to 'docker pull < mirror name'. Because the command is executed directly, without waiting for the result of the response, there is a 2-fold increase in speed. Fig. 4 is a flow chart of asynchronous mirror image pull, and when a mirror image pull instruction is received, each first mirror image file name carried in the mirror image pull instruction and each corresponding pull destination device identification information are obtained. Establishing a parallel mirror image pulling process 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 target equipment based on the parallel image pulling process and the identification information of each pulling target equipment.
Go language, when executing a command line, may return without waiting for a result. The text is described as follows:
4. and deleting the mirror image synchronization.
Command: clusterctl rmi infosec. netauth: 5000/conference-management-server: 1.0.0- -with-registry.
Synchronous deletion refers to deleting the homonymous mirror of the local storage, and then deleting the mirror on the mirror storage server registry. First, the delete operation docker of the registry in the prior art does not provide a command line, and can only operate through the HTTP API. After the operation is encapsulated through the command, the operation and maintenance personnel do not need to deeply know the internal operation mode.
Fig. 5 is a flowchart of an image deletion process provided in the embodiment of the present invention, where 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. And judging whether each second image file name carries preset deleting information (with-registry), and if so, forwarding the image deleting instruction to an image storage server.
