Did you create the network and want to attach the services to it? – Trentontrepan

Answer 1

That seems docker-compose configuration issue, use below docker-compose file, it will create a network and then you can use the same network in the docker-compose file.

version: '3.5'

services:
  webapp1:
    image: nginx:latest
    container_name: my_container
    ports:
      - "8080:80"
    networks:
      - my_network

networks:
  my_network:
    driver: bridge

Also Nginx port should be 80 inside the container if you did not modify the default configuration.

If you see this message, it may be because there is a space before "networks:". Because YAML is space sensitive.
