I am using yaml properties file for the sping boot configuration.
My structure of application.yml is following:
information:
server: ${SERVER_INFO:devserver}
config:
"[http://www.myshop.com]":
- Sam
- Joe
"[https://www.google.com]":
- Mary
... other properties of Map type.
All this values basically represent structure Map<String, List<String>>
where key is site address and List is a array of the users. There could be many entries of this map, I am using this structure to read properties dynamicly.
How my docker container looks:
app:
ports:
- "8080:8080"
build:
... i will skip this info
image: testapp
environment:
- SERVER_PORT=8080
- SERVER_INFO=QAAserver // overrided sucessfully
- INFORMATION_CONFIG=?? // how to pass Map<Sting, List<String>> here?
So, basically, I need an ability to pass values of Map<String, List<String>> from docker compose env var to the spring boot, to override current value. How can I do it?
