Setting up the backend	Starting the backend services

In order to have realtime search running we need:

• deepstream server
• mongodb server
• mongodb replicate (for changefeeds to be enabled)
• realtime-search

Due to the slightly more complex nature of the backend we will let docker-compose manage everything by just using the following commands:

git clone https://github.com/deepstreamIO/deepstream.io-realtime-search.git
cd deepstream.io-realtime-search/example
docker-compose up

Which would result in all the four images being pulled down and run, with deepstream port exposed on 6020

To look a little deeper into it, you'll see that:

• We have a deepstream config.yml file for mongodb configuration:

embed:server/realtime-search/example/conf/config.yml

• A docker compose file + a mongodb script which sets up deepstream, realtime search, mongodb and a mongodb replica (all using the default images):

embed:server/realtime-search/example/docker-compose.yml

Once you run docker-compose up that should be it for the backend!

You can also look at all the CLI commands by running

> docker run deepstreamio/realtime-search mongo --help

Usage: provider mongo [options]

start a mongodb realtime search provider
