I'm trying to make a request from a container to another container within docker and I get a connection refused error.However, if I make the same request using postman, the error does not occur.

I make the request using axios and node.js

url:"http://localhost:8081/project"

async findAllProjects() {
        try {
            const url = URL_BASE_FEED + GET_PROJECTS;
            const request: IHttpRequest<void> = { url };
            const { data, status } = await this.http.get<void, IProject[]>(request);
            return { projects: data, status };
        } catch (error) {
            handleException(error);
        }
    }

error:

cors() middleware is enabled in both containers. The error happens only within docker containers.

  • Does this answer your question? [Connect to another container using Docker compose](https://stackoverflow.com/questions/35749385/connect-to-another-container-using-docker-compose) – Phil Feb 20 '23 at 22:41
  • TL;DR `localhost` is local to the container. If you're trying to connect to another container, you need to use its Docker network address – Phil Feb 20 '23 at 22:41
  • ahh you're right, I must pass the url as an environment variable – Luciano Pulido Feb 20 '23 at 23:16
