Docker-compose：无法将 api 容器连接到 Minio 容器

Question

I'm trying to connect my api server to a minio container, i'm using dockercompose like this:

  minio:
    image: "minio/minio"
    # volumes:
    #   - ./docker-data/minio/data:/data
    command: minio server /data
    networks:
      - backend
    environment:
      MINIO_ACCESS_KEY: 7PDZZCOFGYUASDCBWW9L
      MINIO_SECRET_KEY: cSqaXmYpTk91asduFJ7ZKsZ+8e2pSLOXfc6ycogq
    ports:
      - "9000:9000"
  api:
    image: "applications-api"
    networks:
      - backend
    environment:
      NODE_ENV: test
    ports:
      - 3000:3000
  # command: npm run dockertest

networks:
  backend:

But I keep getting this error, the credentials are the same i cannot understand what i'm doing wrong, I appreciate any kind of help.

Error: connect ECONNREFUSED 172.22.0.2:443

Answer 1

I suspect the problem is your API tries to connect its own container's localhost.

If so, in your API code:

Try using host.docker.internal instead of localhost as minio client endpoint.

This will connect your API to the host's localhost.
