Esto **dependerá mucho** de la forma en que **implementarás tu sistema**, y probablemente estará conectado con la forma en que inicias programas, manejas reinicios, etc.

Aquí hay algunas ideas posibles:

* Un "Contenedor de Inicio" en Kubernetes que se ejecuta antes de tu contenedor de aplicación
* Un script de bash que ejecuta los pasos previos y luego inicia tu aplicación

Now let's build from the previous chapter and add the missing parts to have a complete security flow.

## Get the `username` and `password` { #get-the-username-and-password }

We are going to use **FastAPI** security utilities to get the `username` and `password`.

Bevor wir tiefer in das **Dependency Injection** System eintauchen, lassen Sie uns das vorherige Beispiel verbessern.

## Ein `dict` aus dem vorherigen Beispiel { #a-dict-from-the-previous-example }

Im vorherigen Beispiel haben wir ein <abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">`dict`</abbr> von unserer Abhängigkeit („Dependable“) zurückgegeben:

	dst   chan []jstream.KVS // result of block decode
	err   error              // any error encountered will be set here
}

// Read - reads single record.
// Once Read is called the previous record should no longer be referenced.
func (r *PReader) Read(dst sql.Record) (sql.Record, error) {
	// If we have have any records left, return these before any error.
	for len(r.current) <= r.recordsRead {
		if r.err != nil {
