*This chapter will teach you how to use variables within a fleet.*


Variables in the fleet
------------------------

Go to the **Variables** tab of your fleet. There you will see a list of variables. This list contains only Global and Fleet variables.

Right now you can see the ``UPDATE`` variable that we created earlier.

Variables in fleets can be managed in the same way as any other variable: you can change the name, value, value type and description. To learn how to do that, see REFERENCE TO VARIABLES.

Creating a variable
---------------------

The process of creating a fleet variable is the same as creating a global one (see REFERENCE TO THE VARIABLES SECTION: HOW TO CREATE A GLOBAL VARIABLE). Click the **\"+\"** button, provide a name, value and description, and click **Create**.

Overriding an existing variable
---------------------------------

As mentioned in the Variables chapter <----- REFERENCE, you can override variables. To do so, create a variable with the same name as the variable you want to override. The next screenshot shows how to override the ``UPDATE`` variable:

We are creating the ``UPDATE`` variable with a 12h value, but as you saw, that variable already exists, so after we press **Create**, the Global variable will be overridden for this fleet.
