Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The Flink is a frame and distributed stream batch integrated processing engine, and a platform product based on the Flink framework needs to accurately and conveniently display a Flink cluster state, a task running state, daily monitoring, a running log and the like in the face of different users. The native Web UI page of the flink is used as a carrier for integrating various details such as the scale of a flink cluster, the health degree, the running state of a task and the like, is a part of functions which are required by a product based on the flink framework and can be obtained at a very low cost, and therefore, research and development personnel integrate the Web UI into a platform product based on the flink framework.

In the prior art, for better management and resource isolation, Kubernets are used for container management. Kubernetes, a container management tool, includes a host node and a plurality of computing nodes each communicatively coupled to the host node. The flink cluster runs in Kubernets, and one flink cluster comprises a management node and a slave node. When a fin cluster contains a plurality of management nodes, there may be a plurality of Web UIs that result in the fin cluster, and the address of each Web UI is not fixed. For example, when a master node in a flink cluster fails, a slave node in the flink cluster replaces the failed master node, and the address of the Web UI is transformed.

However, due to security requirements, a user cannot directly access the Web UI and further cannot access nested sub-pages of the Web UI. However, it is a difficult and complicated process to open the access right of the Web UI of the flink cluster for each user.

In order to solve the problem that a user cannot access a Web UI and nested sub-pages of the Web UI, the existing solution is as follows: in the earlier stage, the Web UI is acted based on the function of an application layer, and the general idea is as follows: assuming that a network in which a cluster is located is a first network, a network in which a terminal device of a user is located is a second network, the first network and the second network are different networks, for example, the first network is located in a Virtual Private Cloud (Virtual Private Cloud), and the second network is located in another VPC, the terminal device cannot directly access a Web UI of the cluster. The address of the clustered Web UI in the first network is also referred to as a virtual address. In order to enable the terminal equipment to access the Web UI or the sub-pages, a proxy server is arranged, the Web UI of each flight cluster and the addresses of the nested sub-pages are modified in advance, and the actual Web UI address is used as a parameter of the virtual proxy address. After determining all contents of the Web UI, the proxy server filters the contents, filters out non-links in the contents, and obtains a proxy address by taking an actual address of a link (namely a sub-page) as a parameter. And then, the proxy server transforms the addresses of all the sub-pages in the Web UI into virtual proxy addresses. Therefore, in the process that the user accesses the cluster, no matter the Web UI or the sub-page is, the address is modified into the virtual proxy address in advance, and therefore the user can acquire the Web UI or the sub-page through the proxy server. The link is, for example, a link related to a nested sub page such as HyperText Markup Language (HTML).

The research shows that: the existing proxy mechanism has the following disadvantages:

1. low efficiency and low speed.

Because a plurality of sub-pages are nested in the Web UI, after the proxy server obtains the relevant data of the Web UI, the data are filtered to obtain the addresses of the sub-pages, and the addresses of the sub-pages are also modified, so that the process is time-consuming. Also, when the Web UI contents are excessive, the CPU occupancy is high.

2. The error rate is high.

When the addresses of nested sub-pages are analyzed from the data stream of the Web UI, missing situations easily occur, and when the situation is accessed by a user, situations that the sub-pages do not exist or the authority is limited easily occur.

3. The dynamic subpage is inaccessible.

For the native Web UI of the high-version flink, the addresses of some sub-pages are dynamically spliced in a js function according to the actual environment. The existing proxy mechanism can not deal with the situation because the addresses of the Web UI and the sub-pages are reformed in advance and the addresses of the dynamic sub-pages can not be taken in advance, so that a user can not access the dynamic sub-pages.

Based on this, the embodiment of the present application provides a cluster access method, which is implemented in a brand-new address resolution manner, and by transferring a cluster identifier of a target cluster to a server as a path parameter of a proxy address, so that the server can obtain and return related data of the target cluster, thereby achieving the purpose of quickly accessing the target cluster.

Fig. 1 is a schematic diagram of a cluster system to which a cluster access method provided in the embodiment of the present application is applied. Referring to fig. 1, the present application uses kubernets for container management. Kubernetes, a container management tool, includes a host node and a plurality of computing nodes each communicatively coupled to the host node. A compute node is a workload node and a master node is used to manage and control multiple compute nodes. Multiple containers are deployed in each compute node. Some of the containers are used to form flink clusters, such as flink cluster 1 and flink cluster 2 in the figure.

A flink cluster contains a manager node, also known as master node, and a slave node, also known as worker node. The number of the management nodes can be multiple, a leader (leader) node exists in the management nodes, and when the leader node fails, a standby management node can be upgraded to the leader node. Each flink cluster has a unique cluster identity.

The server is a server which provides pages such as a WeB UI and the like for the user, and the server performs address splicing and the like after receiving the access request, acquires the data stream and sends the data stream to the terminal equipment. The server may include a Web server and a proxy server, which may be integrated or separately located, the Web server and the terminal device being located in the second network, and the proxy server and the cluster being located in the first network. The Web server is used for providing contents displayed by front-end pages and the like for the terminal equipment, and the proxy server is used for accessing the target cluster and returning data streams. Unless otherwise stated, the following description is made by taking an example of an integrated configuration of a Web service and a proxy server.

Hereinafter, the cluster access method described in the embodiment of the present application is described in detail based on the architecture shown in fig. 1. For example, please refer to fig. 2, fig. 2 is a flowchart of a cluster access method provided in an embodiment of the present application, including the following steps:

201. and the terminal equipment displays the cluster list.

Wherein different clusters in the cluster list map different proxy addresses.

Illustratively, a cluster list is displayed on a display screen of the terminal device, each cluster in the cluster list corresponds to a respective proxy address, and a path parameter of the proxy address includes a cluster identifier of the cluster. The proxy address is the address of the parent page of the cluster in the second network.

202. And when the user selects the target cluster in the cluster list, the terminal equipment sends a first access request to the server.

Accordingly, the server receives the first access request.

The first access request is used for requesting to acquire a first data stream of a parent page of a target cluster, the first access request carries a target proxy address of the target cluster, and the parent page comprises information of the target cluster.

Illustratively, a user selects a target cluster in the cluster list by touching, clicking and the like, and triggers the terminal device to send a first access request to the server, where the first access request carries an agent address of the target cluster, and a path parameter of the agent address of the target cluster includes a cluster identifier of the target cluster.

203. And the server determines a first actual address of the target cluster according to the target cluster identifier in the path parameter of the target proxy address of the target cluster.

The first actual address is an address of the target cluster in a first network, the target proxy address is an address of the target cluster in a second network, and the first network and the second network are mutually disconnected.

Illustratively, the first network and the second network are not connected, which means that the first network and the second network are located in a non-passing VPC, etc. Each cluster has a unique cluster identifier, and the server can determine a first actual address of a parent page of the target cluster according to the cluster identifier of the target cluster, wherein the parent page is also called a Web UI (user interface), a home page and the like.

The destination agent address is for example: { proxy Domain }/$ { proxy App Path }/$ { cluster Id }/$ { middle Path }. The proxy Domain is a Domain name machine port of the proxy server, the proxy App Path is a proxy application Path, the cluster Id is a unique identifier (cluster identifier) of a cluster to which the Web UI belongs, and the midle Path is used as a Path buffer, so that nested addresses in the Web UI are prevented from crossing a parent page Path, and the nested addresses cannot reach the proxy.

204. And the server accesses the target cluster according to the first real address to acquire the first data stream.

After the server determines the first actual address, the server can access the target cluster to obtain a first data stream, such as a byte stream, for generating a parent page of the target cluster, where the first data stream includes non-links, and the like.

205. The server sends the first data stream to the terminal device.

Correspondingly, the terminal equipment receives the first data stream sent by the server.

206. And the terminal equipment generates the father page according to the first data stream.

207. And the terminal equipment displays a father page so that the user can view the target cluster on the father page.

Illustratively, the terminal device receives a first data stream and displays a first page of a target cluster through page rendering. Through the home page, the user can check the target cluster state, the task running state, daily monitoring, running logs and the like.

According to the cluster access method provided by the embodiment of the application, when a user accesses a target cluster, the user selects the target cluster from a cluster list displayed by a terminal device, and the terminal device is triggered to send a first access request for requesting to access a parent page of the target cluster to a server, wherein the first access request carries a target proxy address. After receiving the first access request, the server determines a first actual address of a father page according to the cluster identifier contained in the path parameter of the target proxy address, accesses the target cluster according to the first actual address to obtain a first data stream and returns the first data stream to the terminal device, and the terminal device generates the father page of the target cluster according to the first data stream for a user to check the target cluster. By adopting the scheme, the cluster identifier of the target cluster is used as the path parameter of the proxy address and transmitted to the server, so that the server can obtain and return the first data stream for generating the father page.

In the embodiment of the application, an implementation mode of a nested address in a Web UI is utilized: relative addresses, the first data stream used to generate the parent page contains links and non-links. Whenever the address of the parent page is pointed to the proxy server, then the addresses of the nested links, i.e. the addresses of the child pages, all point to the proxy server.

In the embodiment of the present application, a container management is performed by using kubernets, and a cluster is a flink cluster. There may be multiple management nodes in a flink cluster, and due to kubernets scheduling and other reasons, the master node may change, resulting in a change in the first actual address of the parent page of the target cluster. While the cluster identification of the target cluster is unchanged. Therefore, the unique cluster identifier of the target cluster is hidden in the path parameter and is transmitted as the path parameter. And the server identifies a target cluster which the user wants to access according to the cluster identifier, and determines a Web UI address of the target cluster, namely the first actual address, so as to access.

By adopting the scheme, the purpose that the server analyzes the first actual address is achieved by implicitly transmitting the relevant information of the cluster to which the flash WebUI belongs by utilizing the path parameters in the web access path.

In general, many nested addresses are exposed on the parent page of the target cluster, with different nested addresses indicating different child pages. In the existing proxy mechanism, after a first data stream of a parent page of a target cluster is acquired, the first data stream is filtered to obtain link addresses, and the link addresses are transformed into addresses accessible by a proxy server. In the following, how to access the sub-page is explained in detail. Exemplarily, referring to fig. 3, fig. 3 is a flowchart of a cluster access method according to another embodiment of the present application.

The embodiment comprises the following steps:

301. and when the user selects the sub-page identifier of the target sub-page in the parent page, the terminal equipment determines the relative address of the target sub-page.

Illustratively, a parent page is displayed on a terminal device of a user, the parent page is provided with a plurality of click-to-jump controls, and different controls represent different sub-pages. And the user touches or clicks one of the controls through a mouse to trigger the terminal equipment to automatically determine the relative address of the target sub-page. For example, the browser of the terminal device automatically determines the relative address. The relative address is an address relative to the target proxy address of the parent page. For example, the destination agent address is: { proxy Domain }/$ { proxy App Path }/$ { cluster Id }/$ { middle Path }, relative address: { realSourceRelative Path }.

302. And the terminal equipment splices the target proxy address and the relative address to obtain a first spliced address.

Continuing to take the target agent address as: { proxy Domain }/$ { proxy App Path }/$ { cluster Id }/$ { middle Path }, relative address: { realSourceRelative Path } takes as an example, the first splice address is $ { proxyHost: port }/$ { proxyappath }/$ { clusterId }/$ { middlePath }/$ { realradio active Path }.

303. And the terminal equipment sends a second access request to the server.

The second access request is used for requesting to access a target sub-page of the father page, the second access request carries a first splicing address, and the first splicing address is formed by splicing the target proxy address and the relative address of the target sub-page.

304. And the server acquires a second data stream according to the first splicing address.

Illustratively, the server can determine the actual address of the target sub-page according to the first splicing address, and accesses the target cluster according to the actual address of the target sub-page to acquire the second data stream.

For example,

305. and the server sends the second data stream to the terminal equipment.

Illustratively, the server does not need to analyze the data stream, but sends the second data stream to the terminal device in the form of byte stream, thereby greatly improving the data transmission efficiency and reducing the data processing pressure of the CPU.

306. And the terminal equipment generates a target sub-page according to the second data stream.

And the terminal equipment receives the second data stream and displays the sub-page of the target cluster through page rendering. Through the sub-pages, the user can view the target cluster state, the task running state, the daily monitoring or running log and the like.

307. And the terminal equipment displays the target sub-page so that the user can view the target sub-page.

By adopting the scheme, for nested links of child pages such as scripting languages (JavaScript, js) and Cascading Style Sheets (CSS) scripts on a parent page, the server can automatically carry out address splicing according to the target proxy address of the parent page and the relative address of the target child page, and the links in the parent page do not need to be filtered in advance and are not required to be reformed in advance. Therefore, the utilization rate of the CPU can be reduced and the efficiency can be improved.

In the above embodiments, the example is described in which the child page is a child page nested in the parent page. However, the embodiment of the present application is not limited, and in other possible implementations, the sub page may also be a page dynamically generated based on a high version of the flink.

Illustratively, with the advent of high versions of flink, particularly after the flink 1.9 version, some dynamic child pages can be generated, which are not child pages originally nested in parent pages, but child pages that are automatically generated according to the user's operation and some JS scripts or algorithms. Because the existing proxy mechanism is used for transforming the address of the sub-page into the virtual address related to the proxy service in advance, the existing proxy mechanism prevents a user from accessing a page dynamically generated based on a high-version flink.

In the embodiment of the application, the relative address may be a relative address of a nested sub-page or a relative address of a sub-page dynamically generated based on a high-version flink, so that the cluster access method provided by the embodiment of the application can access the sub-page dynamically generated based on the high-version flink.

In the above embodiment, the target cluster includes a master node and a slave node, and when the master node of the target cluster changes, the parent page of the target cluster is updated.

Illustratively, a flink cluster comprises a plurality of main nodes and a plurality of slave nodes, and operations such as kubernets scheduling, user continuous starting and stopping of the cluster lead the flink cluster to be changed continuously, so that a Web UI (user interface) is caused, namely, the address of a father page is large and unfixed, IP (Internet protocol) conversion is difficult to realize on a transmission layer, and some control authority cannot be increased. Therefore, the embodiment of the present application continues to implement the proxy mechanism in a seven-layer proxy manner, i.e., in a manner of doing proxy at the application layer.

In the embodiment of the application, even if the management node of a flink cluster changes, so that the parent page changes, namely the actual address of the parent page changes, the cluster identifier of the flink cluster does not change, and the changed parent page is registered on the proxy server. Therefore, the proxy server can access the parent page according to the cluster identifier. The reason why the actual address of the parent page changes may be, for example: and changing the management node of the target cluster, and the like, thereby realizing high reliability of the target cluster.

In the above embodiment, after the second access request reaches the proxy server, the proxy server analyzes the first splicing address to obtain the target proxy address and the relative address, and can determine the first actual address of the parent page according to the target proxy address, and splice the first actual address and the relative address of the child page to obtain the second splicing address, which is the actual address of the target child page, so as to implement access to the child page. By adopting the scheme, the purpose that the server accurately acquires the related information of the sub-page is achieved.

In the above embodiment, after the server parses the first splicing address to obtain the target address and the relative address, it is further determined whether the relative address is included in a control list, where the control list includes the relative address of the sub-page that restricts the access right of the user. And when the relative address is contained in the control list, determining a second data stream for generating the target sub-page according to the relative address, and returning the second data stream to the server.

And when the relative address is contained in the control list, the server sends prompt information to terminal equipment, wherein the prompt information is used for prompting that the user cannot access the target sub-page.

For example, a control list is pre-stored on the server, and some relative addresses for limiting the user to access are stored in the control list, that is, the user cannot access the sub-pages corresponding to the relative addresses. And after the server analyzes the relative address each time, comparing the relative address with the control list, and if the relative address belongs to the control list, returning prompt information to prompt the user that the target sub-page cannot be accessed. In addition, the server can return other set page contents besides the prompt information. For the resource without system special limitation, the server accesses the real resource address and transmits the data to the user interface in the form of byte stream.

In the above embodiment, before the terminal device accesses the target cluster, a list request is sent to the server to request a third data stream for generating a list page, where the list page is used to display the cluster list. And after receiving the list request, the server generates the proxy address of each cluster. For any cluster, the path parameter of the proxy address of the cluster contains the cluster identifier of the cluster. And then, the server sends a third data stream to the terminal equipment, wherein the third data stream carries the proxy address of each cluster. And after the terminal equipment receives the third data stream, rendering a display page of the cluster list according to the third data stream. By adopting the scheme, the terminal device displays the cluster list for the user to select the target cluster, and the selected cluster can trigger the interaction between the terminal device and the server, so that the problem that the cluster cannot be accessed due to the network failure is avoided.
