Steps to start connector

Users need to follow following steps to start the connector:

1. Provide following details in docker-compose file:

   • Vectra base URL
   • Vectra client_id and client_secret

      environment:
        BASE_URL: <vectra-base-url>
        CLIENT_ID: <vectra-client-id>
        CLIENT_SECRET: <vectra-client-secret>
     

2. Provide destination server details and cron schedules for each APIs in the config.json file.

   {
     "configuration": {
         "server": [
             {
                 "name": "<server-name>",
                 "server_protocol": "<server-protocol>",
                 "server_host": "<destination-server-ip-or-host>",
                 "server_port": <destination-server-port>
             }
         ],
         "scheduler": {
             "audit": "<cron-expression-for-audit>",
             "detections": "<cron-expression-for-detections>",
             "entity_scoring": "<cron-expression-for-entity-scoring>"
         },
         "retry_count": <retry-count>
     }
   }
   

   NOTE: Replace <> values with actual values.

   Find the config.json field description here.

3. In case of TLS servers, provide a TLS configured server certificate(.pem) file in the cert folder.

   • Certificate file name should be the same as the server name provided in config.json.

4. Place config.json, cert folder in the same directory where docker-compose file is present.

   Working directory/
   ├── docker-compose.yml
   ├── config.json
   └── cert/
       └── server1.pem
   

5. Run command 'docker compose up -d' to start the connector.

Note

• User need to restart docker compose in case of any update in config.json. The steps are listed below.
  • Run 'docker compose stop'
  • Make required changes in config.json
  • Run 'docker compose up -d' to start the connector.
• A Dockerfile is provided in the vectra-connector folder but it is not required to build the image locally. A pre-built image has been posted in Docker Hub and is pulled automatically by docker-compose.
