-You can sepcify the variables that are used in the Checks in the Global file `unskript_config.yaml` You can see an example
-of that file in `unskript-ctl` Folder.  This step  be done before you start building your custom docker image.

-* In your `YOUR_REPO_DIRECTORY/actions/` Directory create a file unskript_config.yaml
-   > touch $YOUR_REPO_DIRECTORY/actions/unskript_config.yaml
-* Update the contents of the unskript_config.yaml file like so.
-   ```
-   globals:
-      namespace: "awesome-ops"
-      threshold: "string"
-      region: "us-west-2"
-      services: ["calendar", "audit"]
-   ```
