Вот эксепшн. Уже пробовал и localhost и сделал container_name: db, пробовал сам service в docker-compose менять на db, нет коннекта.

Пока захардкодил DataSourceBuilder.create(), так как думал проверить работает или нет, получается не работает...
@Configuration
public class LiquibaseConfiguration {
@Bean
public SpringLiquibase liquibase() {
SpringLiquibase liquibase = new SpringLiquibase();
liquibase.setChangeLog("classpath:db/changelog/db.changelog-master.yml");
liquibase.setDataSource(dataSource());
return liquibase;
