Set the Security Credentials Using Gradle

Overview

MarkLogic Data Hub creates the following roles:

data-hub-admin-role
flow-developer-role
flow-operator-role

For more information on roles, see Users and Roles

You can specify the usernames and passwords of the accounts associated with these roles, either in the appropriate gradle*.properties file or through the mlUsername and mlPassword options at the command line.

Before you begin

You need:

Java SE JDK 8
MarkLogic Server (See Version Compatibility.)
Gradle 4.6 or later

Procedure

Add the credentials to a gradle*.properties file.

   # You must update this username and password manually.
  # The recommended account to use is one assigned to flow-developer-role.
  mlUsername=flow-developer
  mlPassword=your-flow-developer-password
  ...
  # The flow-developer user is automatically generated by DHF.
  mlFlowDeveloperRole=flow-developer-role
  mlFlowDeveloperUserName=flow-developer
  mlFlowDeveloperPassword=your-flow-developer-password
  ...
  # The flow-operator user is automatically generated by DHF.
  mlFlowOperatorRole=flow-operator-role
  mlFlowOperatorUserName=flow-operator
  mlFlowOperatorPassword=your-flow-operator-password

If the account is specific to an environment, add the credentials to gradle-{env}.properties, where {env} is the environment you are setting up.
If the same account is used in all environments, add the credentials to gradle.properties. *

If you do not want to save the credentials in a file, you can specify the credentials when running the Gradle task at the command line.
