# `keys` Function
|
|
|
|
-> **Note:** This page is about Terraform 0.12 and later. For Terraform 0.11 and
|
|
earlier, see
|
|
[0.11 Configuration Language: Interpolation Syntax](../../configuration-0-11/interpolation.html).
|
|
|
|
`keys` takes a map and returns a list containing the keys from that map.
|
|
|
|
The keys are returned in lexicographical order, ensuring that the result will
|
|
be identical as long as the keys in the map don't change.
|
|
|
|
## Examples
|
|
|
|
```
|
|
> keys({a=1, c=2, d=3})
|
|
[
|
|
"a",
|
|
"c",
|
|
"d",
|
|
]
|
|
```
