Hi all. I’m new to docker. I have a project on asp.net core. It contains 4 projects: 3 microservices and 1 mvc. I configured docker compose in Visual Studio. Everything builds and run greate. Problem is that microservices can’t connect to each other. This is my compose file:
version: ‘3.4’
services:
identity:
image: ${DOCKER_REGISTRY}identity
build:
context: .
dockerfile: src/Services/Identity/IdentityService/Dockerfile
networks:
- backend
children:
image: ${DOCKER_REGISTRY}children
build:
context: .
dockerfile: src/Services/Children/Children.API/Dockerfile
depends_on:
- identity
networks:
- backend
report:
image: ${DOCKER_REGISTRY}report
build:
context: .
dockerfile: src/Services/Report/Report.API/Dockerfile
depends_on:
- identity
- children
networks:
- backend
links:
- "children:children"
webmvc:
image: ${DOCKER_REGISTRY}webmvc
build:
context: .
dockerfile: src/Web Apps/WebMVC/Dockerfile
depends_on:
- identity
- children
- report
networks:
- backend
networks:
backend:
driver: bridge
And docker-compose.override.yml file
version: '3.4'

Below code which send request:
public async Task<IEnumerable<Child>> GetChildren()
{
var uri = Infrastructure.API.Children.GetAll(_childrenByPassUrl);
//temporary hard coded URI
uri = "http://servicescoreexample_children_1:80/api/children";
var responseString = await _apiClient.GetStringAsync(uri);
return string.IsNullOrEmpty(responseString)
? Enumerable.Empty<Child>()
: JsonConvert.DeserializeObject<IEnumerable<Child>>(responseString);
}
Solution (and directory too) are named ServicesCoreExample.
Firstly I think that containers aren’t in one network, so I added a “backend” bridge. When I run docker-compose up and inspect network all containers places in one network.
I tried to set container_name in compose file and to add links. Nothing helps me.
The best result that I got:

It seems like request on http port was accepted but api return BadRequestObjectResult. When all projects run in IIS or just as asp.net core application all is good.
Any suggestions? I just wanted to use docker and comunicate between my services via https
