Question

What is the difference between docker-compose build and docker build?

Suppose in a dockerized project path there is a docker-compo

Answer 1

Adding to the first answer...

You can give the image name and container name under the service definition.

e.g. for the service called 'web' in the below docker-compose example, you can give the image name and container name explicitly, so that docker does not have to use the defaults.

Otherwise the image name that docker will use will be the concatenation of the folder (Directory) and the service name. e.g. myprojectdir_web

So it is better to explicitly put the desired image name that will be generated when docker build command is executed.

e.g. image: mywebserviceImage container_name: my-webServiceImage-Container

example docker-compose.yml file :

version: '3.2'
services:
  web:
    build:
      dockerfile: Dockerfile-alpine
      context: ./web
    ports:
      - 8099:80
    image: mywebserviceImage
    container_name: my-webServiceImage-Container
    depends_on:
      - database
