Any matching `ConfigMap` that is found is processed as follows:
|
||||
|
||||
* Apply individual configuration properties.
|
||||
* Apply as `yaml` the content of any property named `application.yaml`.
|
||||
* Apply as a properties file the content of any property named `application.properties`.
|
||||
* Apply as `yaml` (or `properties`) the content of any property that is named by the value of `spring.application.name`
|
||||
(if it's not present, by `application.yaml/properties`)
|
||||
* Apply as a properties file the content of the above name + each active profile.
|
||||
|
||||
An example should make a lot more sense. Let's suppose that `spring.application.name=my-app` and that
|
||||
we have a single active profile called `k8s`. For a configuration as below:

|

|

====

[source]

----
|

kind: ConfigMap
|

apiVersion: v1
|

metadata:
|

name: my-app
|

data:
|

my-app.yaml: |-
|
||||
...
|
||||
my-app-k8s.yaml: |-
|
||||
..
|

my-app-dev.yaml: |-
|

..
|

someProp: someValue

These is what we will end-up loading:
|
||||
|
||||
- `my-app.yaml` treated as a file
|
||||
- `my-app-k8s.yaml` treated as a file
|
||||
- `my-app-dev.yaml` _ignored_, since `dev` is _not_ an active profile
|
||||
- `someProp: someValue` plain property
|
||||
|
||||
The single exception to the aforementioned flow is when the `ConfigMap` contains a *single* key that indicates
|
||||
the file is a YAML or properties file. In that case, the name of the key does NOT have to be `application.yaml` or
