### Use environment variable as default

You can set a Bake variable to use the value of an environment variable as a default value:
If an environment variable exists with the same name as a declared Bake
variable, Bake uses that environment variable value instead of the declared
default.

To disable this environment-based variable lookup, set
`BUILDX_BAKE_DISABLE_VARS_ENV_LOOKUP=1`.


```hcl
variable "HOME" {
default = "$HOME"
default = "/root"
}
```
