Overview

This document outlines the environment variables required for various containers during the installation or upgrade of KnowHOW. Few sections are marked mandatory, while the rest are optional and depending on the tools in use.

Mandatory configurations

If installing for the first time, provide the following:

  • MONGO_INITDB_ROOT_USERNAME = <DB ROOT USER>

  • MONGO_INITDB_ROOT_PASSWORD = <DB ROOT PASSWORD>

Mandatory configurations

For Upgrading KnowHOW:

  • mongock.start-system-version = <Your current KnowHOW version>

  • mongock.end-system-version = <Version to upgrade to>

  • mongock.migration-scan-package = com.publicissapient.kpidashboard.apis.mongock.upgrade

  • versionnumber = <Version number you are upgrading to>

For First-time Installation:

  • mongock.migration-scan-package = com.publicissapient.kpidashboard.apis.mongock.installation

  • mongock.end-system-version = <KnowHOW version number>

  • forgotPassword.uiHost = <KnowHOW server DNS without https://>

  • corsFilterValidOrigin = <KnowHOW server DNS without https://>

  • spring.data.mongodb.uri = mongodb://<DB USER>:<DB PASSWORD>@mongodb:27017/kpidashboard (URL-encode special characters in the password.)

  • aesEncryptionKey = <AES Encryption Key> (Generate using a random key generator; minimum length: 8.)

  • auth.secret = <JWT token signing secret> (Minimum length: 4.)

  • isRepoToolEnable = <true|false> (Enable or disable SCM.)

  • versionnumber = <Latest version number>

SAML Authentication:

To authenticate and authorize KnowHOW users using SAML

  • auth.subDomainCookie = true

  • auth.domain = <Auth service parent domain>

  • auth.centralAuthBaseURL = https://<Central Auth Backend DNS>

  • auth.resourceAPIKey = <Resource API key> (Generate an API Key by following the steps outlined here. This is required only when running central authentication.)

SCM Processor Setup:

When installing KnowHOW with the SCM Processor (i.e., when isRepoToolEnable=true)

  • exposed_api_key = <API key>

  • repoToolAPIKey = <API key> (Generate an API Key by following the steps outlined here. )

Optional Variables:

  • JAVA_OPTS = <JVM options>

  • DNS_SSL = <Your IP/DNS address>

  • API_HOST = <CustomAPI container name>

  • API_PORT = <CustomAPI port>

SAML Authentication:

To authenticate and authorize KnowHOW users using SAML

  • AUTHENTICATION_SERVICE = true

  • CENTRAL_LOGIN_URL = https://<Central Authentication Service URL>

  • spring.data.mongodb.uri = mongodb://<DB USER>:<DB PASSWORD>@mongodb:27017/kpidashboard

  • aesEncryptionKey = <Same key as defined in CustomAPI>

  • spring.data.mongodb.uri = mongodb://<DB USER>:<DB PASSWORD>@mongodb:27017/kpidashboard

  • aesEncryptionKey = <Same key as defined in CustomAPI>

  • spring.data.mongodb.uri = mongodb://<DB USER>:<DB PASSWORD>@mongodb:27017/kpidashboard

  • aesEncryptionKey = <Same key as defined in CustomAPI>
