Running docker-compose in another Dockerized Container

I’m setting up my development environment and this time around I am using a docker container to run everything… like tmux, vim, etc.

When I run the image that runs my editor I use -v /var/run/docker.sock:/var/run/docker.sock and that way when I use the docker command in the shell of the editor container it links to docker on the host computer and I can run additional docker containers without an issue. This way I can code in my editor container and spin up other containers as dev envs.

However, if I try to run the same Dockerfile from the editor container that worked using docker build and docker run using a docker-compose.yml and docker-compose up I get the following output:

If I preform the same steps on the host machine using the same directory, I get the following normal output:
