Docker Compose v1 and v2 use different separators

When you install Docker Desktop, the latest version of docker-compose (v2) will be included in it. Docker Compose v2 uses dash (-) as the separator for image names, whereas v1 uses underscore (_). The image names in docker-compose.yml for Violet Rails are written according to the naming convention of docker-compose v1.

If your Docker Desktop is using docker-compose v2, it will not be able to find violet_rails_solutions_app image, since it will look for violet_rails-solutions_app.

Open Docker Desktop and go to Images to check which images Docker is using:

• or go to Settings > General and uncheck Use Docker Compose V2.
