# Test data loader
A Docker image that generates test data and loads it into a FHIR store.
The data is generated by [bbmri-fhir-gen](https://github.com/samply/bbmri-fhir-gen), according to the [BBMRI/GBA FHIR profile](https://samply.github.io/bbmri-fhir-ig/overview.html).
The following FHIR resource types will be present in the generated data:
- Patient
- Observation
- Condition
- Specimen
- Organization (for collection and site)
The user can control the naumber of patients generated. The remaining resources are created in proportion to the number of patients.
## Quickstart
The supplied `docker-compose.yml` file can be used for trying things out. It contains a FHIR store (Blaze) and the test data loader. Start it like this:
```
docker-compose up
```
Wait for the test data to finish loading (a couple of minutes). Then try this (in a different console):
```
curl http://localhost:8080/fhir/Patient
```
This should return a list of patients known to the store (all 2000 of them).
## Configuration
The test data loader is configured using environment variables:
| Variable | Description | Default |
|-------------------------------------------|--------------------------------------------------------------------------------------------------------------------|----------------------------------|
| `FHIR_STORE_URL` | HTTP Address of the FHIR store | http://store:8080/fhir |
| `PATIENT_COUNT` | Number of patients to be generated. | 100 |
| `START_DELAY` | Time in seconds before starting upload. | 0 |
| `USE_BRIDGEHEAD_AUTH` | Use Bridgehead-specific authorization credentials to access Blaze. | false |
| `KEEP_ALIVE` | Keep the script alive once it has done its work. | false |
| `WAIT_FOR_BLAZE` | Wait until blaze is ready before starting upload. | false |
You can use the START_DELAY variable if you want to wait for something (typically Blaze) to start before running the data load.
If you set USE_BRIDGEHEAD_AUTH to true, then the script will look in /etc/bridgehead, to see if there is a file called ccp.local.conf or similar, and try to extract the authorization credentials for Blaze from there.
If you set KEEP_ALIVE to true, the script will never terminate. This can be useful if you are working in a Bridgehead environemnt, where terminating containers cause the Bridgehead to shut down.
If you set WAIT_FOR_BLAZE to true, the script will poll blaze every second and only start the upload when it is ready.
## Building
```
docker build -t samply/test-data-loader . --no-cache
```
