Pude avanzar un poco mas. Ahora tengo un error cuando quiero levantar con docker-compose una base LDAP. Copio la salida
root@portal-d:/var/aplicaciones/expedientes/dev/servicios# docker-compose -f ldap.yml -p ldap up -d
WARNING: Service "ldap" uses secret "usuarios_ldap_admin_pass" which is external. External secrets are not available to containers created by docker-compose.

Quise usar de base el yml de expendientes: https://hub.siu.edu.ar/siu/expedientes/-/blob/develop/dev/servicios/ldap.yml
(en dicho yml cambie la imagen del SIU por una propia personalizada y edite las variables de entorno. Ahora, porque se usan secrets ahi si no son compatibles con docker-compose? no me queda clara esa parte.
Ademas veo que es completamente diferente a esta otra parte de la doc de arai: https://documentacion.siu.edu.ar/usuarios/docs/cache/instalacion-bases-ldap/#desplegar
En este ultimo caso tampoco tengo claro como se conectarian entre si, ya que no usan las mismas redes de Docker.
