Kyvos CICD Utility

As a part of the constant endeavor to enhance the ease of working with Kyvos, the Continuous Integration and Continuous Deployment (CI/CD) Utility is created to automate the versioning of Kyvos entities like Semantic Models, Relationships, Datasets, etc., using Git as a versioning tool. It can be used to migrate entities from one Kyvos deployment (Source) to another Kyvos deployment (Target).

• It uses Gitlab to store versions of Kyvos entities in XML format.  

• It also provides integration with Bitbucket repositories.  

• It is a Java-based utility that uses Kyvos REST APIs to export the entities from source Kyvos deployment and import them to target Kyvos deployment. It is designed to be used in Linux systems. 

The CI/CD Utility comprises the following two utilities:

• Export Utility: It fetches entities from Kyvos deployment in XML format, stores them in a local folder, and then pushes them to the configured Git repository. It has a configuration file to define all entities to be fetched along with source Kyvos deployment and git repository details.

• Import Utility: It uses Jenkins to automate the import of entities from the Git repository to target Kyvos deployment.  The Jenkins pipeline is configured in the Gitlab server to pull the entities from Gitlab to the local file system. Jenkins then launches the import utility shell script, which finally imports the entities from the file system to target Kyvos deployment.

Utility bundle details  

The utility bundle contains a single zip file having the following folders and files within it:  

• Conf folder: It contains serverDetailExportUtility.properties, serverDetailImportUtility.properties, and cicdLogs.properties 

• Input folder: It contains an input.json file to configure the exported entities and the Gitlab server details. 

• Lib folder: This folder contains the required libraries for the utility. 

• Output folder: This initially blank folder will place exported entities' XML files when not pushing them into the Gitlab server.

• ExportKyvosEntities.sh: This is a script file to launch the Export utility.  

• ImportKyvosEntities.sh: This is a script file to launch the Import utility.  

Export Utility 

Prerequisites 

1. Git Bash: It is a package that installs Bash, some common Bash utilities, and Git on an operating system. This is needed to execute the Git commands on your system. 

2. GitLab: Git server with main and feature branches. 

Setting up Export Utility 

1. Extract the setup zip file.  

2. Configure source Kyvos deployment details in the serverDetailExportUtility.properties file located in the Conf folder. Provide the following details in this file. If you don't provide the details in the file, you can alternatively provide them as an argument to the export utility script.

   • KYVOS_URL = <YourKyvosURL>/rest/ 

   • USERNAME = <KyvosUserName> 

   • PASSWORD = <KyvosUserPassword> 

3. Configure input.json within the input folder to define the entities to be exported.  The following table provides details of the parameters in the input.json file. 

4. Provide execute permission on ExportKyvosEntities.sh file, using chmod +x ExportKyvosEntities.sh, if not already provided.

Example configurations for different scenarios

• Export All entities from one or more folders

"SEMANTIC_MODEL_DETAILS": {"Folder1" : [], “Folder2”: [] }

"DATASET_RELATIONSHIP_DETAILS": { "Folder1" : [], “Folder2” : [] }

“DATASET_DETAILS": { "Folder1" : [], “Folder2” : [] }

• Export single/multiple entities from ROOT (when entities are not a part of any folder)

"SEMANTIC_MODEL_DETAILS": { "ROOT" : [ “Model4”, “Model5”] }

"DATASET_RELATIONSHIP_DETAILS": {"ROOT": [ “DatasetRelationship4”, “DatasetRelationship5”]}

"DATASET_DETAILS": { "ROOT" : [ “Dataset4”, “Dataset5”] }

• Export ALL entities, which includes all entities at ROOT and all folders with all entities

“SEMANTIC_MODEL_DETAILS": { }

“ DATASET_RELATIONSHIP_DETAILS ": { }

“DATASET_DETAILS": { }

Executing Export Utility

Run ./ExportKyvosEntities.sh $KyvosUrl, $Username, $Password 

The parameters are optional and can be set in the serverDetailExportUtility.properties file. If values are given in both places, the script arguments take precedence.

You can access the execution log file in the conf/log folder containing cicd.log.

Steps performed by Export Utility

1. If the GITPUSH parameter is set as Y, all the entity XML files will be exported to the GitLab Feature branch in the following order.

   1. A GIT PULL is performed from the feature branch specified in the input file to sync the remote and local repository (GITRepo).

   2. The entities are exported to the GITRepo folder from Kyvos, a local repository clone of the GitLab repository.

   3. Entities are then pushed to the GitLab feature branch.

2. The entities are directly exported to the Output folder if the GITPUSH parameter is set as N in the input file. No GIT PULL and GIT PUSH will be performed in this case.

Import Utility

The import utility works in two steps.

Step 1: On changes in the configured Gitlab branch, the Jenkins pipeline triggers to pull the changed files in the local file system; it then launches the ImportKyvosEntities.sh script.

A Jenkins pipeline is required to automate

1. the identification of the change in the configured Gitlab branch and

2. pull the changed entity files into a configured folder within the local file system

3. to launch the ImportKyvosEntities.sh script

Step 2: On execution, the ImportKyvosEntities.sh script reads all the entities xml files placed in the configured folder and uses Kyvos REST APIs to import them in target Kyvos deployment.

If the Jenkins pipeline is not configured, Step 2 can still launch ImportKyvosEntities.sh independently.

Prerequisites

• Git Bash: It is a package that installs Bash, some common bash utilities, and Git on an operating system. This is needed to execute the Git commands on your system.

• GitLab: Git server with main and feature branches.

• Jenkins: For automated execution of the Import utility script, based on a trigger from GitLab.

Setting up Import Utility

1. Extract the setup zip. 

2. Configure source target Kyvos deployment details in the serverDetailImportUtility.properties file in the Conf folder. This file needs the details below to be filled in. If the details are not provided in this file, then alternatively, these details can be provided as an argument to the import utility script.

   • KYVOS_URL = <YourKyvosURL>/rest/

   • USERNAME = <KyvosUserName>

   • PASSWORD = <KyvosUserPassword>

   • KyvosEntitiesPath=<Path of KyvosEntities store in local machine>
     NOTE: It’s value should represent the directory path leading up to the KyvosEntities folder.
     For example:
     /data/Automation_Data/mayank/CICD/CICD_Utility_2023.5/EntitiesInMultipleFolders/CICD_Testing/KyvosEntities

3. Execute the chmod +x ImportKyvosEntities.sh permission on the ImportKyvosEntities.sh file, if not already provided.

Executing Import Utility separately without Jenkins

Execute the following Import Utility separately without Jenkins to perform step 2.

Run ./ImportKyvosEntities.sh $KyvosEntitiesPath $Username $Password $KyvosUrl 

KyvosEntitiesPath is a local machine’s GitLab Repo folder path, storing entities on the pull. This is a mandatory parameter. The other parameters are optional if set in the serverDetailImportUtility.properties file. If values are given at both places, script arguments take the preference.

You can access the execution log file in the conf/log folder, which contains the file named cicd.log.

Jenkins job setup and integration with GitLab Repository

If the Jenkins job is not created and configured, see the Creating new Project in Jenkins section.

If the Jenkins job is not Integrated with the GitLab Repository, see the GitLab settings to integrate with Jenkins section.

Once the above steps are completed, you can execute the Import Utility via Jenkins.

Executing Import Utility via Jenkins

Trigger the Import utility by executing the following pipeline using the Jenkins job.  Once configured, the job will automatically be triggered by webhook whenever you push entities to the main branch.

sh "jenkinsWorkspace/ImportUtilityFilePath ${KyvosEntitiesPath} ${KyvosUsername} ${KyvosPassword} ${KyvosURL}" 

All the parameters are mandatory here. Add these parameters to Jenkins pipeline:

• KyvosEntitiesPath: represents the directory path storing Kyvos entities within the Jenkins workspace dedicated to your project. Data is fetched from the main GitLab repository during the Jenkins workflow and stored in this location. Subsequently, this directory is the source for deploying data to the intended environment.

• KyvosUsername is the name of the native user with admin access to the target Kyvos deployment.

• KyvosPassword is the password of the native user with admin access to the target Kyvos deployment.

• KyvosURL is the URL of the target Kyvos deployment.

  

pipeline {
    agent any
    stages {
        stage ('Environment Details') {
            steps {
                sh '''
                env | grep -e PATH -e JAVA_HOME
                which java
                java -version
                mvn –version"” }}
             stage('Checkout') {
            steps {
                checkout (
                    [$class: 'GitSCM',
                    branches: [[name: '*/your_branch_name']],
                    extensions: [], userRemoteConfigs:
                    [[credentialsId: 'your_credential_id',
                    url: 'your_git_url']]]   ) } }  
        stage('Build') {
            steps {
                script{
                 
                    dir('jenkinsWorkSpacePath/cicdUtilityPath') {
                        sh "pwd"
                sh " jenkinsWorkSpacePath /cicdUtilityPath/ImportKyvosEntities.sh ${kyvosEntitiesPath} ${KyvosUsername} ${kyvosPassword} ${KyvosURL}"     }  } } } } }

• Kyvos Monitor Image displays updated audit logs for imported Datasets, Relationships, and Semantic Model entities post Import utility execution.
