Using several mongodbs with monstache - mongodb

Question

I have a working monstache deployment using docker for elasticsearch and mongodb synchronization. the configuration file is as shown below:
mongo-url = "mongodb://project-db:27017"
elasticsearch-urls = ["http://es7:9200"]
direct-read-namespaces = ["project.data"]
change-stream-namespaces = ["project.data"]
[logs]
error = "./logs/error.log"
[[mapping]]
namespace = "project.data"
index = "Project"
[[script]]
namespace = "project.data"
path = "./scripts/collection.js"
routing = true
However, I need to add several other databases like 10 of them. mongo-url is a string. Is there a way to add several mongodb sources for indexing?

Monstache seems reasonably light. I'd recommend using multiple dockers in a docker compose setup. Something like so:
version: '3.5'
networks:
proxynet:
name: proxynet
driver: bridge
services:
mongodb:
networks:
- mongodbnet
- proxynet
ports:
- 27017:27017
container_name: mongodb
image: mongo:4.2.17
command: --auth --replSet mongoset
volumes:
- /path/to/docker/mongodb/data:/data/db
restart: unless-stopped
elasticsearch:
container_name: elasticsearch
networks:
- proxynet
ports:
- 9200:9200
- 9300:9300
environment:
- "discovery.type=single-node"
- ELASTIC_PASSWORD=random
volumes:
- /path/to/docker/elasticsearch/data:/usr/share/elasticsearch/data
image: elasticsearch:7.5.2
restart: unless-stopped
monstache01:
networks:
- proxynet
image: rwynn/monstache
container_name: monstache
ports:
- 8080:8080
working_dir: /monstache
command: -f ./monstache.toml
volumes:
- /path/to/monstache01:/monstache
depends_on:
- elasticsearch
- mongodb
restart: unless-stopped
monstache02:
networks:
- proxynet
- mongodbnet
image: rwynn/monstache
container_name: monstache
ports:
- 8081:8080
working_dir: /monstache
command: -f ./monstache.toml
volumes:
- /path/to/docker/monstache02:/monstache
depends_on:
- elasticsearch
- mongodb
restart: unless-stopped
