I'm having trouble using the Azure Cosmos Emulator running in Docker. When run my app, I get the following error while trying to connect to the DB:
connection error: MongoNetworkError: failed to connect to server [localhost:10255] on first connect [Error: connect ETIMEDOUT 127.0.0.1:10255
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1129:14) {
name: 'MongoNetworkError',
[Symbol(mongoErrorContextSymbol)]: {}
}]
As per the Running on Docker instructions, I pulled the image and ran
md %LOCALAPPDATA%\CosmosDBEmulator\bind-mount
docker run --name azure-cosmosdb-emulator --memory 2GB --mount "type=bind,source=%LOCALAPPDATA%\CosmosDBEmulator\bind-mount,destination=C:\CosmosDB.Emulator\bind-mount" --interactive --tty -p 8081:8081 -p 8900:8900 -p 8901:8901 -p 8902:8902 -p 10250:10250 -p 10251:10251 -p 10252:10252 -p 10253:10253 -p 10254:10254 -p 10255:10255 -p 10256:10256 -p 10350:10350 mcr.microsoft.com/cosmosdb/windows/azure-cosmos-emulator
mongodb://localhost:C2y6yDjf5%2FR%2Bob0N8A7Cgv30VRDJIWEHLM%2B4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw%2FJw%3D%3D@localhost:10255/admin?ssl=true
I am able to access the explorer on https://localhost:8081/_explorer/index.html so the emulator is running.
I'm using mongoose in app

After some frustrated head scratching, I found the solution! Based off the Docker container page for the emulator instructions, you need to run the following docker command:
docker run --name azure-cosmosdb-emulator --memory 2GB --mount "type=bind,source=%LOCALAPPDATA%\CosmosDBEmulator\bind-mount,destination=C:\CosmosDB.Emulator\bind-mount" --interactive --tty -e AZURE_COSMOS_EMULATOR_MONGODB_ENDPOINT=true -p 8081:8081 -p 8900:8900 -p 8901:8901 -p 8902:8902 -p 10250:10250 -p 10251:10251 -p 10252:10252 -p 10253:10253 -p 10254:10254 -p 10255:10255 -p 10256:10256 -p 10350:10350 mcr.microsoft.com/cosmosdb/windows/azure-cosmos-emulator
The important change is the addition of: -e AZURE_COSMOS_EMULATOR_MONGODB_ENDPOINT=true
Update:
I have since found this enables the 3.2 protocol, for the 3.6 protocol you will need to use: -e AZURE_COSMOS_EMULATOR_MONGODB_COMPUTE_ENDPOINT=true
More discussion is available in this github discussion, where someone also pointed out that the Gremlin & Casandra options are:
-e AZURE_COSMOS_EMULATOR_GREMLIN_ENDPOINT=true
-e AZURE_COSMOS_EMULATOR_CASSANDRA_ENDPOINT=true
