I found workaround for this problem. If there is NO property spring.config.import in application.properties file then environment variables from Docker, Docker Compose and Kubernetes work file.

Problem is when I try to run this service manually from command line tool. I have to use command with parameter spring-boot.run.arguments then:

mvn -f ./springcloud-fe-thymeleaf-be-springboot-db-sql-mysql-config_BE spring-boot:run -Dspring-boot.run.arguments="--spring.config.import=configserver:http://localhost:8888"
