-#### Variable types
+#### Types of variables
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/issues/46806) in GitLab 11.11.
There are two types of variables supported by GitLab:
-- "Variable": the Runner will create an environment variable named same as the variable key and set its value to the variable value.
-- "File": the Runner will write the variable value to a temporary file and set the path to this file as the value of an environment variable named same as the variable key.
+- [Variable type](#variable-type): The Runner will create an environment variable named the same as the
+ variable key and set its value to the variable value.
+- [File type](#file-type): The Runner will write the variable value to a temporary file and set the
+ path to this file as the value of an environment variable, named the same as the variable key.
-Many tools (like [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html) and [kubectl](https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/#the-kubeconfig-environment-variable)) provide the ability to customise configuration using files by either providing the file path as a command line argument or an environment variable. Prior to the introduction of variable types, the common pattern was to use the value of a CI variable, save it in a file, and then use the newly created file in your script:

echo "$KUBE_CA_PEM" > "$(pwd)/kube.ca.pem"
- # Use the newly created file
+# Pass the newly created file to kubectl
kubectl config set-cluster e2e --server="$KUBE_URL" --certificate-authority="$(pwd)/kube.ca.pem"
```
-This can be simplified by creating a variable of type "File" and using it directly. For example, let's say we have the following variables.
