What is the difference b/w a docker image generated by docker-compose build vs docker build?

While building a docker image, image id is different if the image is built using docker-compose build vs docker build. The env has different hostname.

What else is different? Why images are different?

There are no differences between the actual image that gets built between docker-compose build and a "manual" docker build in terms of the contents of the image.

The difference is only in naming/tagging of the build result, which docker-compose does automatically for you. Other than that, the docker-compose build is no different behind the scenes and simply a wrapper for the normal docker build.

In addition to the naming difference, there could be difference in the resulting image if the parameters of the builds are different: the build: section of the docker-compose.yml and the command line parameters of the docker build command. For example the --build-args can be different.
