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

• Change to cstoreservice directory

   cd cstoreservice

• Invoke multistage build

  docker build -t dicomdemos/dicomstorescp:1.0 -f Dockerfile-multistage .    ```
  

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
