As shown in fig. 2, the embodiment includes operations S210 to S230, and the installation method of the cloud-native application may be performed by a server.

In operation S210, a helm chart software package is constructed according to the deployment situation of the cloud native application.

Helm is a Kubernets package manager (i.e., software package manager), and is the best way to find, share, and use the software built by Kubernets. Helm Charts (software package) is a series of YAML files used to encapsulate Kubernets native applications. Some Metadata of an application may be customized at the time the application is deployed by a user to facilitate distribution of the application.

For application (such as cloud native application) publishers, applications can be packaged by Helm, application dependencies can be managed, application versions can be managed, and applications can be published to the software repository; for users (such as application installers), the application program can be searched, installed, upgraded, rolled back and uninstalled on Kubernets in a simple mode without writing complex application deployment files after Helm is used.

With the help (package manager), packages can be quickly found, downloaded and installed like the apt used in Ubuntu, yum used in Centos or the pip in Python.

In operation S210, an application developer may build a palm chart software package according to a deployment situation of an application (i.e., a cloud native application). A template file, which may be a key configuration value predefined value file, may be used to collect all configuration items into one value.

In operation S220, in response to the user determining the palm chart software package, a form corresponding to the palm chart software package is generated and displayed.

For example, a user views a palm chart software package in a software repository in a WEB page, and selects the palm chart software package for installation (i.e., the user determines the palm chart software package). And responding to the fact that the user determines the palm chart software package, generating a corresponding dynamic form, and displaying the form to the user.

In operation S230, in response to a first configuration item input in the form by the user, a palm chart software package manager corresponding to the first configuration item is called to install the cloud-native application.

The user can install the software package through a web page mode, for example, an application installer inputs a key configuration item (first configuration item) according to actual requirements. In response to a first configuration item input in the form by the user, starting to call a palm chart software package manager corresponding to the first configuration item to install the cloud native application.

According to the installation method of the cloud native application, a palm chart software package is constructed according to the deployment condition of the cloud native application; responding to the fact that a user determines a palm chart software package, generating a form corresponding to the palm chart software package and displaying the form; and responding to a first configuration item input in the form by the user, and calling a palm chart software package manager corresponding to the first configuration item to install the cloud native application. The visual design is realized by displaying the form; when interacting with an application installer, the application installer can directly input a key configuration item (namely a first configuration item) in the form, and execute the installation of the cloud native application by means of the palm chart software package manager according to the content of the key configuration item, so that the cloud native application is installed in a what-you-see-is-what-you-get manner.

According to the deployment situation of the cloud native application, a palm chart software package is constructed, and the steps comprise: and according to the deployment condition of the cloud native application, predefining metadata parameters of the palm chart software package.

Metadata is defined as: data describing the data, descriptive information for the data and information resources. Metadata (Metadata) is data (data about other data) describing other data, or structural data (structured data) for providing information about a certain resource. Metadata is data that describes an object such as an information resource or data, and is used for the purpose of: identifying a resource; evaluating the resources; tracking changes of the resource in the using process; the method realizes simple and efficient management of a large amount of networked data; the information resources are effectively discovered, searched and integrally organized, and the used resources are effectively managed.

The basic characteristics of metadata are as follows: a) once the metadata is established, it can be shared: the structure and integrity of the metadata depend on the value and use environment of the information resources; the development and utilization environment of metadata is often a varied distributed environment; neither format can fully satisfy the different needs of different groups. b) Metadata is a coding scheme: metadata is an encoding system used to describe digital information resources, especially network information resources, which results in fundamental differences between metadata and conventional data encoding systems; the most important feature and function of metadata is to build a machine understandable framework for digitized information resources. Since metadata is also data, it can be stored and retrieved in a database in a data-like manner. The use of data elements will be made accurate and efficient if the organization of the data elements is provided while the metadata describing the data elements is provided. The user may first view his metadata when using the data in order to be able to obtain the information he wants.

The method for installing the cloud native application provided by the embodiment is used for constructing a palm chart software package, and comprises the following steps: the metadata parameters of the palm Chart software package are predefined. Since metadata is data that describes data and is shareable once established, a changing distributed environment can be achieved by predefining metadata parameters, thereby generating a dynamic form.

Responding to the fact that a user determines a palm chart software package, generating a form corresponding to the palm chart software package and displaying the form, wherein the steps of: and responding to the fact that the user determines the palm chart software package, generating a form corresponding to the palm chart software package according to the metadata parameter of the palm chart software package, and displaying the form.

Different Metadata parameters defined according to the palm chart software package. And dynamically rendering different page forms by using the metadata parameters, so that a corresponding page does not need to be designed for each software package, and various different software packages can be conveniently accessed and decoupled from a WEB platform.

According to the installation method of the cloud native application provided by the embodiment, according to the difference of each software or application, when the software or application leaves a factory, a page form rendering form during later installation is configured through predefined visual configuration metadata, so that a user can install the cloud native application conveniently in a form of a dynamically configurable form.

According to the deployment situation of the application, building a helm chart software package, which further comprises the following steps: according to the deployment condition of the application, at least one of a list file of a pod of the predefined helm chart software package, a Template file of the predefined helm chart software package and a value list of the predefined helm chart software package.

Helm (software package manager) is equivalent to a package management tool yum of the Linux system, and managed software packages are some packaged manifest files. Helm chart is a Helm chart software package that may contain a manifest file of predefined pod, which may include: configuration information such as Service, Deployment, daemon set, repliaset, stateful set, HPA, etc. it is needless to say that the above list files do not always include all the configuration information, and the contents included in the list may be different according to different applications. Template is a Template file, and because a configuration list can be suitable for various scenes, some custom configurations need to be made according to the use scenes of a user, such as: HTTPS is configured in the Nginx configuration list, a configuration certificate is needed, but the certificate cannot be packaged into Chart in advance, a mechanism is needed to adapt to the custom requirements by means of passing variables, Template exists for the purpose, and a value list (values. Reproducibility: is Helm's Chart (software Package) warehouse, supports HTTPS/HTTP. And (3) Release: s is an example of a particular Chart deployed on a target K8s (Kubernets) cluster.

According to the installation method of the cloud native application, a user can conveniently manage the palm chart software package through at least one of the list file of the pod of the predefined palm chart software package, the Template file of the predefined palm chart software package and the value list of the predefined palm chart software package.

In response to a first configuration item input in a form by a user, invoking a palm chart software package manager corresponding to the first configuration item to install a cloud native application, including: generating a second configuration item in response to the first configuration item input in the form by the user; according to the second configuration item, a palm chart software package manager is called to install the cloud native application.

According to the installation method of the cloud native application, the second configuration item is generated by responding to the first configuration item input by the user in the form, the installation difficulty of an application installer can be reduced, if the application installer only needs to input some key configuration items, the second configuration item (such as a complete configuration item) can be automatically generated, and therefore the palm chart software package manager is called to install the cloud native application according to the second configuration item, and user experience is greatly improved.

The installation method of the cloud native application further comprises the following steps: in response to a first configuration item input in the form by the user, a resolution corresponding to the first configuration item is determined, so that the form shows the resolution corresponding to the first configuration item.

According to the installation method of the cloud native application, the software package is installed in a WEB-UI visual mode, corresponding analysis is performed for help explanation aiming at each configuration item, the installation difficulty of a user is reduced, if the user refers to the corresponding analysis, the installation can be performed only by clicking input on a page, and the cloud native application is installed in a what you see is what you get mode.

The installation method of the cloud native application further comprises the following steps: responding to a first configuration item input in the form by a user, and verifying the first configuration item according to a preset verification rule; and sending an error prompt when the checking result is error.

For example, the input of the user (first configuration item) is checked according to a preset check rule. When the user inputs an error, an error prompt is sent to allow the user to correct the current input.

The installation method of the cloud native application provided by this embodiment can provide a verification function, avoid an installation problem caused by an erroneous input (first configuration item), reduce installation difficulty, and improve installation power.

The installation method of the cloud native application comprises the following steps that a first configuration item comprises at least two configuration items, and the method further comprises the following steps: determining whether a mutual exclusion relationship exists between the configuration items aiming at least two configuration items; and sending an error prompt under the condition that the mutual exclusion relationship is determined to exist.

The installation method of the cloud native application provided by this embodiment may check the plurality of configuration items, for example, check whether a mutual exclusion relationship exists between the plurality of configuration items.

The installation method of the cloud native application provided by the embodiment provides a diversified data verification function, avoids the installation problem caused by the mutual exclusion relationship among configuration items, can reduce the installation difficulty, and improves the installation power.

Fig. 3 schematically illustrates a schematic diagram of an installation method of a cloud-native application according to an embodiment of the present disclosure. Referring to FIG. 3, a dynamic form 301, a rendering engine API302, a software package manager 303, a first input check 304, a second input check 305, and an installation manager 306 are included.

The dynamic form 301 is used to interact with an application installer, rendering a form generated from the application through front-end js. The rendering engine API302 is primarily used to extract metadata definition documents of key configuration items from the software package, which specify how the front-end dynamic form should be displayed, how to interact with the installer. The rendering engine API302 can check metadata format and logic, understanding the configuration items in metadata. And then generating data which can be understood by the front js, returning the data to the dynamic form module, and enabling the dynamic form module to work according to the data. The package manager 303 is used to manage the packages, similar to a package repository, to which all the lm charts are accessed and which defines the metadata document of the key configuration item (e.g. the first configuration item). The first input check 304 is used to check the user input according to the check rule generated by the rendering engine API. When the user inputs an error, an error prompt is returned, so that the user can correct the error prompt conveniently. The second input check 305 may be used in conjunction with the first input check 304, for example, to check that the front end cannot check, such as mutual exclusion relationship among multiple configuration items; the second input check 305 may also be used alone. The installation manager 306 may be used to manage the installed software packages for the user to later maintain the installed applications (i.e., cloud-native applications). Such as upgrading, modifying configurations, etc.

Fig. 4 schematically illustrates an execution flowchart of an installation method of a cloud-native application according to an embodiment of the present disclosure; as shown in fig. 4, this embodiment includes operations S401 to S412.

In operation S401, an application software developer constructs a palm characters installation package according to the deployment condition of an application (cloud native application). Such as template file and key configuration value predefined value file, all configuration items are collected into one value. Then, according to the format and type of the configuration in the values.yaml, etc., a verification manner for rendering the values.metadata.yaml file of the installation form and regarding the key configuration item (first configuration item) is defined. Such as integer configuration, value range, a normal IPv4 address, etc. Value, metadata, yaml is put in a peer directory with value, yaml and is packed into a normal helm characters software package through helm.

In operation S402, the packaged helm characters software package is uploaded to the software warehouse platform.

In operation S403, it is determined whether the software package passes the verification. For example, the software warehouse checks the uploaded package, mainly parsing the definition values. If the parsing fails (i.e., the software package fails to be checked), operation S405 executes to return an error prompt.

If the software package passes the verification, the application installer operates S404 to view the installation package in the software repository in a web page, and select the installation package for installation.

In operation S406, the rendering engine and the front end render into a corresponding dynamic form according to the defined values.

In operation S407, the application installer inputs a key configuration item (first configuration item) according to the actual situation and the prompt.

In operation S408, it is determined whether the first check passes. When an error is input, operation S410 is performed, the configuration item cannot be submitted, and error details are displayed.

When the application installer completes the submission of the configuration item and passes the first check, operation S409 is performed, for example, the first configuration item is provided to the backend system for checking at the logic level. If the second check is not passed, operation S412 is executed to return an error prompt.

In operation S411, that is, after the second verification is passed, according to data (such as the first configuration item) provided by the front end, predefined values.yaml contents in the palm characters software package are covered, all merged configuration items (such as the second configuration item) are generated, and a call to the palm characters software package manager corresponding to the first configuration item is started to install the cloud native application.
