# FDO Manager Service

**This is WIP - don't use it unless you want to break things.**

Reference implementation of a RESTful Service API for basic FDO operations.
This service exposes the functionality of the
[FDO Manager SDK](https://gitlab.com/fairdo/fdo-manager/sdk).


## Build JAR

```
mvn clean package
```

This results in `application/target/fdo-manager-service.application-${version}.jar`

## Run

Either build the application and start the JAR with

```
java -jar application/target/fdo-manager-service.application-${version}.jar
```

or start it directly from maven with

```
mvn spring-boot:run
```

### Use Mockup Repository

Build the JAR file, then run

```
java -Dmock=true -jar application/target/fdo-manager-service.application-${version}.jar
```

### Request

By default you can access the service at `http://localhost:8081/api/v1`. Try

```
curl http://localhost:8081/api/v1/hello
```

### API Specs

You can view the API specs at `http://localhost:8081/api/v1/swagger-ui/index.html`.

### Stop

Stop the running service with `CTRL-C`.

## Troubleshooting

### Exception on startup

When running the mockup repository as described above, the following exception is shown:
```
java.io.IOException: ERROR: cannot read repository config directory: repositories
        at com.indiscale.fdo.manager.service.ManagerPool.getConfig(ManagerPool.java:58)

        at java.base/java.lang.Thread.run(Thread.java:1570)

```

This configuration is not needed for the mockup repository and can be ignored.
