Override application.yml with environment variable in Spring boot

Question

I need my application should pick value of a key from environment variables instead of application.yml.

If a particular property is available in both environment variables as well as in appliation.yml then it should pick the value which is specified as part of environment variables.
If a particular property is not there in environment variables then it should pick value from application.yml else not.

This is the default behavior of spring. Doesn't it work for you out of the box? — Roman-Stop RU aggression in UA, Nov 20 '19 at 09:26

For your two questions. You can use something like:

spring:
  profiles: ${YOUR_ENV_FOR_PROFILE:YOUR_DEFAULT_PROFILE}

If you set an environment variable(Ex. YOUR_ENV_FOR_PROFILE) then spring use it, otherwise spring use a default value "YOUR_DEFAULT_PROFILE"

Why complicate things? This should run out of the box in Spring Boot. No need for complex syntax here. – Stefan Haberl Nov 20 '19 at 10:58
