How to start CosmosDB emulator with docker-compose?

Question

I've got a docker-compose project in Visual Studio which starts 3 services. One of them use cosmosdb.

I've followed the instructions on https://hub.docker.com/r/microsoft/azure-cosmosdb-emulator/ to start the emulator in a docker container and it worked.

But now I want to get it up and running through docker-compose file. Following is my current configuration.

version: '3.4'

services:
  gateway:        
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
    image: ${DOCKER_REGISTRY-}gateway
    ports:
      - "7000:80"
    depends_on:
      - servicea
      - serviceb
    build:
      context: .\ApiGateways\IAGTO.Fenix.ApiGateway
      dockerfile: Dockerfile

  servicea:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
    image: ${DOCKER_REGISTRY-}servicea
    depends_on: 
      - email.db
    build:
      context: .\Services\ServiceA
      dockerfile: Dockerfile

  serviceb:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
    image: ${DOCKER_REGISTRY-}serviceb
    build:
      context: .\Services\ServiceB
      dockerfile: Dockerfile

  email.db:
    image: microsoft/azure-cosmosdb-emulator
    container_name: cosmosdb-emulator
    ports:
      - "8081:8081"

I can see the container running when I run docker container list

But requests to https://localhost:8081/_explorer/index.html fails.

Any help on this much appreciated

Answer 1

I was in the same situation but the container was started with the following docker-compose.yml and it became accessible.

I can browse https://localhost:8081/_explorer/index.html

version: '3.7'

services:
    cosmosdb:
        container_name: cosmosdb
        image: microsoft/azure-cosmosdb-emulator
        tty: true
        restart: always
        ports:
            - "8081:8081"
            - "8900:8900"
            - "8901:8901"
            - "8979:8979"
            - "10250:10250"
            - "10251:10251"
            - "10252:10252"
            - "10253:10253"
            - "10254:10254"
            - "10255:10255"
            - "10256:10256"
            - "10350:10350"
        volumes:
            -  vol_cosmos:C:\CosmosDB.Emulator\bind-mount
        
volumes:
    vol_cosmos:   

Probably I needed to set "tty" or "volumes".
