Does config subtititue quarkus. properties with QUARKUS_ envs?

[agreedSkiing]

If I have quarkus.datasource.blocking.jdbc.url = ${quarkus.datasource.jdbc.url:jdbc:postgresql://localhost:5433/quarkus} will it then use the variabel export QUARKUS_DATASOURCE_JDBC_URL when running?

Yes. Even for substitutions, the lookup rule still applies.
