Override application.properties used in Docker

[rapetum228]

Hello, I am interested in how I can override the application.properties file. I run integrations through Docker, in Portainer. In Portainer it is possible to create a service based on an image and override some files of this image in the container. I would like to know if it is possible to do the same for Camel Karavan images?
Other options of overriding are also welcome (for example, creating several application.properties for different environments).
In your repository you have such a folder https://github.com/apache/camel-karavan/tree/main/karavan-demo/placeholder, which has two files application.properties and local.properties. What is the correct way to use it? Help me, please.🙏🏻

You could use environment properties placeholders ex: ${env:APP_HOME} and set env variables for container

Thank you. Indeed, variables defined in application.properties in Docker are interpreted as ENVs in a special way.
For example, let's write 2 variables in application.properties:

myrabbit.host = localhost
test.variable = 1

Their equivalent is in Docker ENVs, which can be overridden: MYRABBIT_HOST, TEST_VARIABLE
