Inside accounts folder run
mvnw spring-boot:run
It starts accounts microservice. accounts microservice uses an in-memory database. It seeds database by sample data on startup. If accessing an external port has limited in your organization, this command (mvnw spring-boot:run) won't work. In the accounts folder run something like flowing command instead.
java -jar target/product1-0.0.1-SNAPSHOT.jar
Inside bank-ui folder in command run
ng serve --proxy-config proxy.conf.json
It starts bank-ui Angular web application. For watching communication logs you can use --verbose option, like this.
ng serve --proxy-config proxy.conf.json --verbose
Inside microservice-test(root) folder in command run
docker-compose -f "docker-compose.yml" up -d --build
It creates related docker images and starts both bank-ui Angular web application and backend accounts microservice containers. This way bank-ui can call backend microservice by its container name and related Url.
