@ -80,7 +80,7 @@ Docker Cloud allows you to define build environment variables either in the hook
In the following example, we define a build hook that uses `docker build` arguments to set the variable `CUSTOM` based on the value of variable we defined using the Docker Cloud build settings. `$IMAGE_NAME` is a variable that we provide with the name of the image being built.
```none
docker build --build-arg CUSTOM=$VAR -t $IMAGE_NAME
docker build --build-arg CUSTOM=$VAR -t $IMAGE_NAME .
```
> **Caution**: A `hooks/build` file overrides the basic [docker build](/engine/reference/commandline/build.md) command
