Managing Parameters

CloudTruth Parameters exist across all of your Environments in a project and can be made up of a combination of internal and external values. Parameters can also be marked as Secret which will mask the Parameters value and store it in your organizations dedicated managed vault. Parameters are always scoped to the selected project.
Parameter
Definition
​Internal​
User defined value per Environment
​External​
Value obtained from a CloudTruth integration​
​Secret​
Masked Parameter Values protected by Vault
In addition you can apply validation to your parameter values by bounding the value to a specific type and set custom rules that apply across all environments. You can also mark the Parameter as Dynamic which allows you to reference other parameters and templates in the value.
Adding an Internal Parameter Value
Select a Project to create a Parameter in.
From the Parameter Store page click Add Item to create a new parameter.
Enter a Parameter name, you can select whether the parameter is a secret and provide a description. Expand the Rules to add an optional type and constraints for the parameter.
Click Create Parameter.
The Parameter is created in the default Environment and you can enter an Internal, External or empty value as the Parameter default. Add an Internal value and Click Save.
Secrets
Mark the parameter as a secret to store it in your organizations dedicated vault. Values for Parameters created with the 'secret' option will not be displayed by default wherever the secret is referenced.
Using this option prevents the unnecessary display of sensitive data when performing routine configuration tasks.
Password generation
We provide the ability to automatically generate secure random passwords for you and allow you to specify your minimum requirements. Select the Show Password Generator dropdown.
Dynamic Parameters
Marking a Parameter value as Dynamic allows you to reference and interpolate other values and templates from the project.
This parameter evaluated_demo contains a value with text evaluated_memory_size: that includes the value from a referenced project parameter {{service.app.memory}}.
Clicking Show Evaluated displays the evaluated value for the referenced parameter.
Dynamic values cannot be secrets, meaning they cannot be stored in your organization's vault, but they CAN reference secrets. If you have secret information you'd like to use in a dynamic value, store it in a secret Parameter and reference it in your dynamic value.
Overriding Parameter Values
Parameters are present in all of the Environments in a project and by default are set to the value from the parent Environment. You can set a unique Parameter value for each Environment by overriding the value.
Click on a Parameter from the Parameter Store list.
The Parameter details page is displayed. In this example we have three Environments (Production, Dev and Staging) under the default parent.
Select the Environment where you would like to override the value and click Edit Value.
The Edit Environment Value page is displayed, set the Parameter value for the selected Environment and click Save.
Now the Parameter details page shows the updated value for the selected Environment. The remaining Environments retain the default value.
Inline Value Edits
Parameters can also be edited from the Parameters, Compare and History pages. On each page the 
 will allow you to directly edit the value for a specific environment or remove an override. The Compare page will allow you to edit values for each environment selected in the compare.
Searching Parameters
As your Parameter list grows you can use the search to find all parameters with a specific string within your project.
From the Parameter Store page you can list all Parameter values for a specific Environment by selecting the Environment in the drop down box. Values that have overrides for the selected Environment are indicated in the Value Source.
Edit Parameter Settings
Select the Parameter you want to edit from the Parameter Store page and click Edit Parameter Settings from the Parameter menu.
The Edit Parameter dialogue allows you to update the description, change whether the parameter is a secret and update or set rules.
Deleting Parameters
Select the Parameter you want to edit from the Parameter Store page and click Delete Parameter from the Parameter menu.
Template References
The Parameter settings page will display the number of Templates a given Parameter is referenced in. You can navigate to each Template from the Template List tab. Parameters that are referenced in a template are protected from deletion.
