# Advanced YAML syntax
|
|
|
|
## Anchors & aliases
|
|
|
|
You can use [YAML anchors & aliases](https://yaml.org/spec/1.2.2/#3222-anchors-and-aliases) as variables in your pipeline config.
|
|
|
|
To convert this:
|
|
```yml
|
|
pipeline:
|
|
test:
|
|
image: golang:1.18
|
|
commands: go test ./...
|
|
build:
|
|
image: golang:1.18
|
|
commands: build
|
|
```
|
|
|
|
Just add a new section called **variables** like this:
|
|
|
|
```diff
|
|
+variables:
|
|
+ - &golang_image 'golang:1.18'
|
|
|
|
pipeline:
|
|
test:
|
|
- image: golang:1.18
|
|
+ image: *golang_image
|
|
commands: go test ./...
|
|
build:
|
|
- image: golang:1.18
|
|
+ image: *golang_image
|
|
commands: build
|
|
```
|
|
