[DOCS] Create More Detailed Installation and Usage Instructions

[jspeed-meyers]

👋 I'd be grateful for more detailed installation and usage instructions. I've been struggling to use the container that is created from the Dockerfile and I can't figure out if it's my own fault (user error) or a bug. I suspect that part of my confusion stems from sparse installation and usage instructions. Thank you for creating this cool project!

I thought I would provide my intent, the steps I was following, and the error I encountered.

My intent: I am trying to connect the container built with the Dockerfile in this repo to a container running an instance of MongoDB.

The steps I followed:

I create a network for the containers to share.

docker network create my_network

I then start a mongo instance on this network.

docker run --name some-mongo -d -p 27017:27017 --network my_network mongo:latest

I build the image for the testing tool with the Dockerfile.

git clone https://github.com/mongodb/mongo-perf && cd mongo-perf

docker build --tag=mongo-perf/mongo-perf:test . 

I then run the newly created container.

docker run -it --network my_network mongo-perf/mongo-perf:test -f  testcases/simple_insert.js -t 1 2 4 --host localhost

The error:

MongoDB shell version v5.0.8
connecting to: mongodb://localhost:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server localhost:27017, connection attempt failed: SocketException: Error connecting to localhost:27017 (127.0.0.1:27017) :: caused by :: Connection refused :

Error: Command '['mongo', '--norc', '--host', 'localhost', '--port', '27017', '--eval', "print('db version: ' + db.version()); db.serverBuildInfo().gitVersion;"]' returned non-zero exit status 1.

There’s a connection error. I’ve tried and failed to debug it.

I'm running this on an Apple M1 Pro (Sonoma 14.5) with Docker version 20.10.21, build baeda1f.

Hey pal!

Your host is wrong, you should be using the name of your mongo container as host, in your case should be something like docker run -it --network my_network mongo-perf/mongo-perf:test -f testcases/simple_insert.js -t 1 2 4 --host some-mongo

That's all I can help though, I've been stuck in some other tests here, but as the README said its supposed to be an internal tool, I don't know if they are going to give any support for this
