After using YAML for a long time, for many, many Kubernetes manifest files, I have today learnt that it contains two multiline value types (called scalars):
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
scalarsExample:
|
||
|
|
literalScalar: |
|
||
|
|
Literal scalars use the pipe (`|`) to denote the start of the value with the scope indicated by indentation.
|
||
|
|
All content here is used literally, with newlines preserved.
|
||
|
|
<-- This is the start of the line, the spaces before this aren't included in the literal.
|
||
|
|
This should be used when storing things like file contents (e.g. in a ConfigMap)
|
||
|
|
foldedScalar: >
|
||
|
|
Folded scalars use the greater-than symbol (`>`) to denote the start of the value with the scope indicated by indentation.
|
||
|
|
Unlike literal scalars newlines aren't preserved and instead converted into spaces.
|
||
|
|
<-- This is the start of the line, the spaces before this aren't included in the value.
|
||
|
|
This should be used when you'd normally use a string but the contents are long and wrapping makes it easier to read.
|
||
|
|
