Variables

Variables is poverfull mechanism for customization.List of variables and values for deployment you can see on the specifications tab.

Additionaly in project configuration we can create more variables.

If you use helm chart in your service - the variables tab will contain a lot of variables parsed from values.yaml file. You can edit this vars and get changes in resulting yaml.

This variables specified for service and are not available in other services in the same project.

Let`s try to add new variable and save

Then you can see your variable in deployment sync vars.

Good.

Now you can use this var in your yaml

But that is not all.

Value sources for variables

You can select where take a value for this variable.

You can select one of this options:

Values defined at a Project Level	The simplest - hardcoded value in this form
Deployment Specific Variables	The link to other existed variable (copy value from other variable)
Deployment Configuration	Most useful - Take the value from deployment configuration UI. You can have a different values in different deployments. Unified dynamically create UI for your service configuration.

For our test var TestVar will set type Deployment Configuration and check deployments configuration. You will see a new tab and input for your variable.

Change this value and check the resulting yaml.

Variable types

You can define variable type and Variable input type.

• Variable type - like in programming languages with strong typization. can be a boolean, string, number, array, map. (Type any means that unifie will not change your variable type. It will use the exact value.)

• UI Variable Input Type - Affect only for UI.

Type conversion is important for kubernetes.  For example, such params as "replicas" or "containerP
