+
+  Comma separated list of terraform vars to set.
+
+  This is deprecated due to the following limitations:
+  - Only primitive types can be set with `var` - number, bool and string.
+  - String values may not contain a comma.
+  - Values set with `var` will be overridden by values contained in `var_file`s
+
+  You can change from `var` to `variables` by putting each variable on a separate line and ensuring each string value is quoted.
+
+  For example:
+  ```yaml
+  with:
+    var: instance_type=m5.xlarge,nat_type=instance
+  ```
+  Becomes:
+  ```yaml
+  with:
+    variables: |
+      instance_type="m5.xlarge"
+      nat_type="instance"
+  ```
