Therefore, according to the embodiment of the application, when a user manages the Kubernets cluster, the Kubernets cluster can be managed through the browser, the corresponding main node does not need to be logged in, and the corresponding Kubernets cluster can be downloaded according to user requirements for managing Kubernets cluster, so that the problems that in the prior art, when the user manages the Kubernets cluster through kubecectl, the corresponding main node needs to be logged in, the operation is complex, the convenience is insufficient, the version of kubecectl is fixed, the Kubernets cluster of the corresponding version cannot be selected according to user requirements, and the Kubernets cluster is not flexible are solved.
In step S102, receiving a kubecect service creation request sent by a user through a browser includes:
receiving a kubecect service creation request sent by a user through clicking a creation control on a Kubernets cluster management page; wherein the Kubernetes cluster management page is displayed through a browser.
Specifically, a Kubernetes cluster management page is displayed on a browser, such as a World Wide Web browser, after a user clicks a creation control on the page, the browser sends a creation kubecect service request to a Master node of the Kubernetes cluster through a transmission protocol, and the Master node receives the request. A create control, such as a create service button, a transport protocol, such as the HTTP protocol.
In step S102, the kubecect service creation request carries the kubecect service version information input by the user through the browser.
Specifically, the user can input the kubecect service version information required by the user through the browser, and the kubecect service creation request sent by the browser carries the kubecect service version information input by the user through the browser. In a specific embodiment, a Kubernets cluster management page displayed by a browser is provided with a plurality of check boxes, a kubecectel service version represented by each check box is marked beside each check box, a user checks the check boxes to represent that the user needs kubecectel service of the version, the user clicks a kubecectel service creation button on the page after checking the check boxes, a kubecectel service creation request sent by the browser carries kubecectel service version information represented by the check boxes checked by the user, and the kubecectel service creation request carries the kubecectel service version information input by the user through the browser.
Further, after the step S102 is completed, before the step S104, that is, before downloading the kubecect service corresponding to the kubecect service version information into the container of the kubernets cluster according to the kubecect service creation request, the method further includes:
(a1) acquiring a user identifier of a user;
(a2) and judging whether the user has the authority of creating the kubecect service or not according to the user identification of the user.
In the step (a1), after receiving the kubecenetes cluster Master node creation request sent by the user through the browser, the Master node may further obtain, through the browser, a user identifier of the user, where the user identifier is, for example, a user name used by the user to log in a Kubernetes cluster management page.
In the step (a2), after acquiring the user identifier of the user, the Master node of the Kubernetes cluster queries the right corresponding to the user identifier in the database, and determines whether the user has the right to create the kubecect service according to the right corresponding to the user identifier.
Further, if the Master node of the kubernets cluster determines that the user has the right to create the kubecectel service, step S104 is performed to download the kubecectel service corresponding to the kubecectel service version information to the container of the kubernets cluster. If it is determined that the user does not have the right to create the kubecect service, returning rejection information to the browser and not performing step S104, for example, displaying on a kubernets cluster management page: "creation of kubecect without permission".
In the step S104, downloading the kubecect service corresponding to the kubecect service version information to the container of the kubernets cluster according to the kubecect service creation request includes:
(b1) creating a Deployment according to the creation request of the kubecect service, and defining kubecect service version information in a container environment variable of the Deployment;
(b2) when a container group is started through the Deployment, reading kubecect service version information from a container environment variable of the Deployment, and downloading kubecect service corresponding to the kubecyte service version information to a container of a Kubernetes cluster.
In the step (b1), after determining that the user has the right to create the kubecenetes cluster, the Master node of the Kubernetes cluster starts to create a namespace, then creates a service account, binds the service account with the cluster role after creating the service account, and creates a Deployment as the controller of the container group after binding the cluster role. The construction content of the Deployment comprises that kubecect service version information is defined in a container environment variable, and the kubecect service version information is kubecect service version information input by a user through a browser. The specific implementation flow of step (b1) can be seen from the description of fig. 2 below.
In this embodiment, in the step (b2), reading the kubecect service version information from the container environment variable of the delivery, and downloading the kubecect service corresponding to the kubecect service version information to the container of the kubernets cluster includes:
(b2.1) extracting a specific script file from a previously acquired image file for starting the container group;
(b2.2) executing a specific script file, wherein the specific script file is used for reading the kubecect service version information from the container environment variable of the Deployment and downloading the kubecect service corresponding to the kubecenetes cluster container.
In the step (b2.1), the kubernets cluster has a preset image file for starting the container group, and the image file contains a specific script file. When the Master node creates the Deployment, the construction content of the Deployment comprises the address of the image file, and the image file is pulled according to the address of the image file so as to extract the specific script file in the image file. In a specific embodiment, an image file of the kubernets cluster for starting the container group is stored in a Docker warehouse, where the Docker warehouse centrally stores the image file, and the image file is based on the following steps: 3.10 System creation.
In step (b2.2), when the container group in the delivery is started, a specific script file is executed, and the script file reads the container environment variable of the delivery to obtain the kubecect service version information input by the user through the browser, then accesses the download website corresponding to the kubecect service version set in the script, and downloads the binary file of the kubecect service version into the container of the delivery.
After the step S104 is completed, that is, after the kubutect service is created, the step S106 may be performed to receive a cluster management request sent by a user through a browser, and manage a kubernets cluster based on the cluster management request and the kubutect service.
In step S106, the receiving of the cluster management request sent by the user through the browser includes:
receiving a kubecect cluster management request sent by a user through clicking a management control on a Kubernets cluster management page; wherein the Kubernetes cluster management page is displayed through a browser.
Specifically, a Kubernetes cluster management page is displayed on the browser, after a user clicks a management control on the page, the browser sends a cluster management request to a Master node of the Kubernetes cluster through a transmission protocol, and the Master node receives and processes the request. The management control is, for example, a manage cluster button, and the cluster management request is, for example, a Web Socket request.
Further, in step S106, before managing the kubernets cluster based on the cluster management request and the kubecect service, the method further includes:
(c1) acquiring a user identifier of a user;
(c2) and judging whether the user has the authority of managing the Kubernetes cluster or not according to the user identification of the user.
In the step (c1), after receiving the cluster management request sent by the user through the browser, the Master node may further obtain, through the browser, a user identifier of the user, where the user identifier is, for example, a user name used when the user logs in a kubernets cluster management page.
In the step (c2), after acquiring the user identifier of the user, the Master node queries the right corresponding to the user identifier in the database, and determines whether the user has the right to manage the kubernet cluster according to the right corresponding to the user identifier.
Further, if the Master node of the kubernets cluster determines that the user has the authority to manage the kubernets cluster, the management of the kubernets cluster may be performed based on the cluster management request and the kubecect service in step S106, and if it is determined that the user does not have the authority to manage the kubernets cluster, the reject information is returned to the browser and the next step is not performed, for example, the display on the kubernets cluster management page: "No permission to use kubecect".
In step S106, a kubernets cluster is managed based on the cluster management request and the kubecfect service, specifically, after the Master node determines that the user has the authority to manage the kubernets cluster, a TTY (TeleTYpe, virtual console, serial port, and pseudo terminal device) connection is established with a container in the container group, that is, a terminal connection with the container is established, after the TTY connection is established, the browser displays a page using the kubecutet service, and the user can operate on the page to manage the kubernets cluster, for example, a kubernets cluster executes a corresponding command by inputting a kubecfect command on the page, so that the user manages the kubernets cluster using the kubecutet service through the browser.
Further, when the user uses the kubecectl service to manage the kubernets cluster, the method provided in this embodiment further includes:
(d1) acquiring behavior data which is executed by a user and is related to management of a Kubernetes cluster;
(d2) and storing the behavior data into a database, wherein the behavior data is used for auditing the user.
Specifically, in step (d1), the Master node may obtain, through a connection established with the browser, for example, a Web Socket connection, a behavior data flow generated when the user manages the kubernets cluster through the browser using a kubecect service.
In the step (d2), after acquiring the behavior data stream, the Master node copies and formats the behavior data stream, and stores the formatted data into a database for viewing data records of a user management Kubernetes cluster and auditing the user.
In a specific embodiment, fig. 2 is a specific flowchart of a cluster management method provided in an embodiment of the present application.
As shown in fig. 2, the kubernets cluster includes a Master Node and a work Node, the Master Node includes a user right control module, a logic processing module, a kubernets API (Application programming interface), a king namespace, a king service account, a cluster role "cluster-admin", a mirror image file king-kubutect for starting a container group, a user behavior auditing module, and a database, and the work Node includes a Deployment, a container group Pod, a container, a kubutect service, and a specific script file king-kubutect.
As shown in fig. 2, after the user clicks the create service button, the Web browser sends a create kubecect service request to the user permission control module, where the request carries kubecect service version information input by the user, and after receiving the request, the user permission control module queries the database and determines whether the user has permission to create kubecect service according to the user identifier, if so, the request is delivered to the logic processing module, and if not, the "no permission to create kubecect" is returned to the browser. After receiving and processing the request for creating the kubutect service, the logic processing module sends a request for creating a namespace to the kubernets API, after receiving the request, the kubernets API creates a namespace, the name of the namespace can be preset, for example, king, all the created resources are under the namespace, and the namespace can be used for resource isolation of the kubutect service. After the king namespace is created, the kubernets API can then create a service account named king, after the service account king is created, the logic processing module binds the service account king with a cluster role "cluster-admin" preset by the kubernets, so that the service account king has all the rights of the cluster role cluster-admin, for example, the rights of viewing containers, editing containers and the like in the kubernets cluster. After the cluster role binding is established, the Kubernets API establishes the Deployment, and the construction content of the Deployment comprises the following steps:
(1) the name of the Deployment, which is preset;
(2) the namespace of the Deployment is the created king namespace;
(3) the container group Pod of the Deployment uses the service account, i.e. the container group uses the created king service account, so that the container group Pod of the Deployment has all rights of the cluster role "cluster-admin".
(4) The name of the container in the Pod, which is preset;
(5) the mirror image file address used for starting the container, this file is set up in advance;
(6) the environment variable of the container defines the kubecect service version information;
(7) the lifecycle management command of the Pod, which is executed to execute a specific script file king-kubutect.
In this way, when the container group in the Deployment is started, the script is executed, the script reads the environment variable of the container in the Deployment, acquires the kubecect service version information input by the user, and then accesses the corresponding website in the internet and downloads the kubecect binary file into the container.
After the Deployment is completed, the Web browser sends a WebSocket request to a user authority control module according to the operation of clicking a cluster management button by a user, after the user authority control module receives the request, a database is inquired, whether the user has authority to manage a Kubernet cluster is judged according to user identification, if the user has the authority, the request is transmitted to a logic processing module, if the user does not have the authority to use kubecect, the logic processing module returns no authority to use kubecect to the browser, after receiving and processing the request, the TTY connection is established between the browser used by the user and a Pod in a container group Pod through a Kubernet API, after the connection is established, the browser displays a page using kubecect service, and the user can input a kubecect command line on the page to manage the Kubernet cluster. The logic processing module can copy a Web Socket data stream generated by managing a Kubernetes cluster on the page by a user and transmit the copy to the user behavior auditing module, and the user auditing module uniformly stores the data processed in a database for the user to audit in the future.
In summary, it can be seen that the present embodiment has the following beneficial effects:
(1) the Kubernetes cluster can be managed by using the kubecect service through one key of the Web browser without logging in a Master node of the Kubernetes cluster, and the operation is simple and convenient.
(2) The kubecect service of different versions can be downloaded according to the requirements of users, and the kubecect service of multiple versions is supported, so that the method is more flexible.
(3) The authority control of the user can be realized, and the safety of creating the kubecectl service and managing the Kubernets cluster is ensured.
(4) The operation of managing the Kubernetes cluster by the user is recorded in the database, so that the user behavior audit in the future is facilitated.
(5) By adopting the Deployment mode of the Deployment, if the server deployed by the container fails, the server can be automatically migrated to other servers, so that the normal running state of the container is ensured.
In summary, particular embodiments of the present subject matter have been described. Other embodiments are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may be advantageous.
