# Using detached applications
|
||
|
|
|
||
|
|
All the other samples use an application that is deployed **inside of an instance**. However, you can also deploy an application **detached** from the instance as a solo chart.
|
||
|
|
|
||
|
|
The reason for this is, that you
|
||
|
|
|
||
|
|
- can update the instance without running the application update
|
||
|
|
- update the application without touching the instance
|
||
|
|
- have multiple applications deployed within one instance
|
||
|
|
|
||
|
|
There are two major things you need to do:
|
||
|
|
|
||
|
|
1. make sure the application charts sets the instance name of the instance, it should connect to
|
||
|
|
2. take the default values of the application match the ones it would get by an instance deployment
|
||
|
|
|
||
|
|
This is a sample: (find the complete one in the [application.yaml](application.yaml))
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
nameOverride: SBS
|
||
|
|
docAreas:
|
||
|
|
- id: "SBS"
|
||
|
|
name: "DocArea with SBS"

|
|
# this is the name of the instance, it should belong to
|
||
|
|
name: "sample-detached"
|
||
|
|
|
||
|
|
# make sure it can wait for the nappl of the instance to be ready, before it deploys.
