# uaa
This application was generated using JHipster 5.4.2, you can find documentation and help at [https://www.jhipster.tech/documentation-archive/v5.4.2](https://www.jhipster.tech/documentation-archive/v5.4.2).
This is a "uaa" application intended to be part of a microservice architecture, please refer to the [Doing microservices with JHipster][] page of the documentation for more information.
This is also a JHipster User Account and Authentication (UAA) Server, refer to [Using UAA for Microservice Security][] for details on how to secure JHipster microservices with OAuth2.
This application is configured for Service Discovery and Configuration with the JHipster-Registry. On launch, it will refuse to start if it is not able to connect to the JHipster-Registry at [http://localhost:8761](http://localhost:8761). For more information, read our documentation on [Service Discovery and Configuration with the JHipster-Registry][].
## Development
To start your application in the dev profile, simply run:
./mvnw
For further instructions on how to develop with JHipster, have a look at [Using JHipster in development][].
## Building for production
To optimize the uaa application for production, run:
./mvnw -Pprod clean package
To ensure everything worked, run:
java -jar target/*.war
Refer to [Using JHipster in production][] for more details.
## Testing
To launch your application's tests, run:
./mvnw clean test
For more information, refer to the [Running tests page][].
### Code quality
Sonar is used to analyse code quality. You can start a local Sonar server (accessible on http://localhost:9001) with:
```
docker-compose -f src/main/docker/sonar.yml up -d
```
Then, run a Sonar analysis:
```
./mvnw -Pprod clean test sonar:sonar
```
For more information, refer to the [Code quality page][].
## Using Docker to simplify development (optional)
You can use Docker to improve your JHipster development experience. A number of docker-compose configuration are available in the [src/main/docker](src/main/docker) folder to launch required third party services.
For example, to start a mysql database in a docker container, run:
docker-compose -f src/main/docker/mysql.yml up -d
To stop it and remove the container, run:
docker-compose -f src/main/docker/mysql.yml down
You can also fully dockerize your application and all the services that it depends on.
To achieve this, first build a docker image of your app by running:
./mvnw package -Pprod jib:dockerBuild
Then run:
docker-compose -f src/main/docker/app.yml up -d
For more information refer to [Using Docker and Docker-Compose][], this page also contains information on the docker-compose sub-generator (`jhipster docker-compose`), which is able to generate docker configurations for one or several JHipster applications.
## Continuous Integration (optional)
To configure CI for your project, run the ci-cd sub-generator (`jhipster ci-cd`), this will let you generate configuration files for a number of Continuous Integration systems. Consult the [Setting up Continuous Integration][] page for more information.
