Weasis-Manager

Weasis-Manager allow to manage Weasis viewers on an IT Infrastructure.

Architecture

Main functionalities

• Launch of Weasis viewers (several launch endpoints, including IHE IID Profile-compatible launch)
• Creation and association of user or machine groups
• Creation of an xml file (manifest) containing the studies, series and instances to be downloaded. This file will then be transmitted to Weasis to load the images into the viewer.
• Manifest storage in a redis cache
• Storage of resources required by the different versions of Weasis on Minio/S3
• Creation of versions of Weasis launched only for certain groups
• Live changed of Weasis properties
• Versions management of i18n translations used by Weasis
• Compatibility management between versions of Weasis installed on clients and versions of resources uploaded in Weasis-Manager (storage on Minio S3 + cache)
• Pacs connectors management
• Retrieve OAuth2 tokens on IDP to enable Weasis to authenticate on dcm4chee pacs
• Cryptography of launch urls

Launch the different containers in local

If you want to launch all the containers:

• Via the terminal, go to the folder "docker": cd docker

• Launch via the following docker command:

docker compose -p imaging_hub -f docker-compose.yml -f docker-compose.local.yml up -d

• Or launch via this command script:

  ./scripts/start.sh local

Minio

The service "create-bucket" in docker-compose.local.yml will launch the creation of a bucket and an access key for weasis-manager.

It is also possible to create the bucket/access key manually:

• Access to the Minio console:

http://localhost:9090

with

User: weasis-manager
Password: weasis-manager

• Once logged, go to Administrator -> Buckets and fill the bucket name with "weasis-manager-bucket", then create the bucket.

• Then go to User -> Access Keys and create the access key "access-key" with the secret key "secret-key"

Keycloak

In order to access to the keycloak console:

http://localhost:8085

with

User: admin
Password: admin

When launching Keycloak with the docker-compose file keycloak.yml in the docker folder, a configuration is directly imported in the keycloak container. This configuration will create:

• a realm "weasis-manager"
• a client "weasis-manager" in order for the manager to connect with the authorization grant type "authorization_code"
• a user "weasis-manager-user" which will have a role "admin" associated in order to access to the different "secured" views of the manager

Dcm4chee

In order to access to the pacs dcm4chee:

http://localhost:8080/dcm4chee-arc/ui2/en/study/study

As an example, you can import the file "dicom-example" located in the folders "docker -> dcm4chee" by using the dcm4chee interface.

Run configuration

• Configure the run configuration and add in VM options the following properties:

  -Duser.timezone=UTC
  -DENVIRONMENT=local
  -DEUREKA_CLIENT_SERVICE_URL_DEFAULT_ZONE=http://localhost:8761/eureka
  -DREGION=local
  -DDATACENTER=local
  -Dserver.port=8081
  -Dmanagement.server.port=19001
  -DBACKEND_URI=http://localhost:8081
  -DDB_HOST=localhost
  -DDB_PORT=45101
  -DDB_NAME=weasis-manager
  -DDB_USER=weasis-manager
  -DDB_PASSWORD=weasis-manager
  -DCONFIGSERVER_URI=http://localhost:8888
  -DS3_ACCESS_KEY=access-key
  -DS3_SECRET_KEY=secret-key
  -DS3_ENDPOINT=http://localhost:9080
  -DS3_BUCKET_NAME=weasis-manager-bucket
