Init Bundle

Init Bundle is a simple approach to creating configuration resources when starting Aidbox.

It is equivalent to just executing Bundle in Aidbox using POST /fhir. There are some differences:

1. It is executed before the internal HTTP server starts, and before the health check response.
2. Unsuccessful execution of the init bundle of type transaction prevents Aidbox from starting.
3. Unsuccessful execution of the init bundle of type batch triggers warnings in the log; Aidbox continues the startup process.
4. Aidbox startup will be interrupted if the specified file is unavailable or is not a valid bundle resource of transaction or batch type.
5. Only JSON format is supported.

Usage

Specify BOX_INIT_BUNDLE env. The value must be an URL.

BOX_INIT_BUNDLE=<URL>

Examples of URLs:

• file:///tmp/bundle.json
• https://storage.googleapis.com/<BUCKET_NAME>/<OBJECT_NAME>

Example

If a Bundle file is created at /tmp/bundle.json:

{
  "type": "batch",
  "resourceType": "Bundle",
  "entry": [
    {
      "request": {
        "method": "POST",
        "url": "/Observation",
        "ifNoneExist": "_id=o1"
      },
      "resource": {
        "id": "o1",
        "code": {
          "text": "text"
        },
        "status": "final",
        "effectiveDateTime": "2000-01-01"
      }
    }
  ]
}

Aidbox will apply it if the BOX_INIT_BUNDLE is set to:

BOX_INIT_BUNDLE=file:///tmp/bundle.json

Hints

1. First, check that Aidbox handles the Bundle as it should using POST /fhir. Try to post it several times to make sure it is idempotent. Then add it to BOX_INIT_BUNDLE.
2. Note that the Aidbox format is not supported.
3. Aidbox handles an id in the body of the POST request. That's why posting the resource with an id twice will cause an duplicate key error. Use conditional create or update for that.
