    Specifying path to configuration file

    Once installed, CloverDX Server requires the configuration of essential (database connection, license, sandboxes) and optional (SMTP, LDAP authentication, SAML, etc.) features. The configuration is done by specifying configuration properties in a [property-key]=[property-value] format.

    The configuration might contain sensitive data; therefore, CloverDX Server enables you to encrypt the configuration properties (for more information, see Securing configuration properties).

    CloverDX can load the configuration properties from several sources. We recommend the easiest, most convenient way:

    Configuration file on specified location

    The cloverServer.properties configuration file is a text file which contains all CloverDX settings. You can edit the file either manually, or using a simple and intuitive Setup GUI.

    For an example configuration file, see Example configuration file.

    The path to the file can be specified by system property, context parameter or environment variable.

    We recommend specifying the path with the clover.config.file system property.

    Example for Apache Tomcat:

    Edit bin/setenv.sh (or bin\setenv.bat) and add -Dclover.config.file=/absolute/path/to/cloverServer.properties to CATALINA_OPTS.

    For more information and examples on the supported application containers, see Specifying path to configuration file.

    Alternative configuration sources

    There are other sources of configuration properties, as well. Each source containing the configuration data has a different priority. If a property isn’t set, application’s default setting is used.

    Combining configuration sources could lead to a confusing configuration which would make maintenance much more difficult.

    • Environment Variables

      Environment variables are variables configured by means of your operating system (e.g. $PATH is an environment variable).

      There are two ways of configuration via environment variables:

      • direct override - using environment variables with the same name as the configuration properties and adding the clover. prefix. For example, the environment variable clover.sandboxes.home will override the configuration property sandboxes.home.

        Some operating systems may not use a dot (.) character, so underlines (_) may be used instead of dots. So the clover_config_file name works as well.

      • placeholders - configuration properties can reference environment variables using the ${env:ENVIRONMENT_VARIABLE} syntax. For instance, sandboxes.home=${env:SANDBOXES_ROOT}.

        Placeholders can be used in all CloverDX Server properties. If placeholder must not be resolved, use doubled '$' character, e.g. security.ldap.user_search.filter=(sn=$${username}).

    • System Properties

      System properties are configured by means of JVM, i.e. with the -D argument (-Dclover.config.file).

      Set a system property with the clover. prefix, i.e. (clover.config.file).

      Underlines (_) may be used instead of dots (.) so the clover_config_file name works as well.

      System properties can also be referenced from within placeholders in all CloverDX Server properties. For instance, sandboxes.home=${sys:user.home}/sandboxes.

    • Configuration File on Default Location

      A text file containing configured CloverDX properties. By default, CloverDX searches for the file on the [AppServerDir]/cloverServer.properties path.

    • Modification of Context Parameters in web.xml

      This way isn’t recommended, since it requires a modification of the WAR file, but it may be useful when none of the approaches above are possible.

      Unzip clover.war and modify the WEB-INF/web.xml file. Add the following piece of code into the file:

      <context-param>
    <param-name>[property-name]</param-name>
    <param-value>[property-value]</param-value>
</context-param>

    • Context Parameters (Available on Apache Tomcat)

      Some application servers allow you to set context parameters without modification of the WAR file.

      This way of configuration is possible, but it is not recommended, as Apache Tomcat may ignore some context parameters in some environments. Using the configuration file is almost as convenient and much more reliable.

      Example for Apache Tomcat:

      On Tomcat, it is possible to specify context parameters in a context configuration file [Tomcat_home]/conf/Catalina/localhost/clover.xml which is created automatically just after deployment of the CloverDX Server web application.

      You can specify a property by adding this element:

      <Parameter name="[propertyName]" value="[propertyValue]" override="false" />

      (Note: by setting the override attribute to false), the context parameter does not override the default setting associated with the owning host.)

    Priorities of configuration sources

    Configuration sources have the following priorities (from the highest to lowest):

    1. Context parameters

      Context parameters are specified in an application server or directly in a web.xml file (not recommended).

    2. External configuration file

      The path to the external configuration file can be specified in several ways. CloverDX Server attempts to find the file in this order (only one of them is loaded):

      1. the path specified with a config.file context parameter;

      2. the path specified with a clover_config_file or clover.config.file system property (recommended);

      3. the path specified with a clover_config_file or clover.config.file environment variable;

      4. the default location ([AppServerDir]/cloverServer.properties).

    3. System properties

    4. Environment variables

    5. Default values

    Specifying path to configuration file

    Setup uses the configuration file to save the Server’s settings. The path to the file is specified by the clover.config.file system property. Each application server has a different way to configure the path:

    • Apache Tomcat

      Edit bin/setenv.sh (or bin/setenv.bat) and add -Dclover.config.file=/absolute/path/to/cloverServer.properties to CATALINA_OPTS.
