Docker based Dicom CStore Service

This project demonstrate load balanced Docker deployment of DICOM CStore service.

Overview

DICOM CStore service implemented using DCM4CHEE Java library. Service is deployed inside Docker and instances are scaled and load balanced using nginx.

Build requirements

Java 17 or higher
Functioning Docker setup

Build instructions - Using multistage docker build

Checkout repository

 git clone https://github.com/madhub/dicomservices.git

Regular Build instructions

Checkout repository

 git clone https://github.com/madhub/dicomservices.git

Change to cstoreservice directory
```
 cd cstoreservice
```
Build fat jar
```
gradlew.bat clean jar
```

Build Docker image

docker build -t dicomdemos/dicomstorescp:1.0 .

Confirm Docker image is created successfully
```
docker images
```

Deploying service into Docker

Service is deployed using docker-compose with nginx load balancing DICOM assoication across instances. By default nginx port 4040 published to host. Port 4040 used for all DICOM communications

Change to deployment\docker directory

   docker-compose up --scale dicomstorescp=3

Verify the DICOM connectivity
- Using DCMTK tools
```
  echoscu  localhost 4040 
```
- Using DCM4CHEE Tools
```
   storescu  -c store-scp@localhost:4040 
```
