Vim .vimrc

Note the format:

Vim docker-compose.yml

Version: "3" services: nginx: container_name: web-nginx image: nginx restart: always ports:-90:80 volumes: -. / webserver:/usr/share/nginx/html

The first part: version: specifies the version of the syntax format.

The second part; service: define the service (what kind of container you want to run)

/ / run the container specified by docker-compose. PS; also needs to have a docker-compose.yml configuration file in the current directory where this command is executed.
