docker-compose with multiple options to enable dbt's serve docs functionality - docker

Question

I am trying to generate/access documentation for dbt via this guide: https://docs.getdbt.com/reference/commands/cmd-docs. The issue is I am getting a 'This Site Cant Be Reached'. So I am referencing this post DBT docker: Docs Served but Not Accessible via Browser - which notes to add --publish to my docker-compose. Currently I have a makefile with the line below:
docker-compose -f docker-compose.yml
I would think to change it to the below but does not seem to work.
docker-compose -f docker-compose.yml -p
as I get the error:
Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "-p": executable file not found in $PATH: unknown
As well, I tried to edit the docker-compose.yml file to include the below:
version: '3.9'
services:
localdev:
build: .
image: localdev:latest
ports:
- "80:80"
- "8080"
- "8080:8080
stdin_open: true
tty: true
environment:
- ENV=my-env
- ADD_PATH=/bin/docker
volumes:
- $LOCAL_REPO_DIR:/usr/app/code
- /var/run/docker.sock:/var/run/docker.sock:ro
- /usr/local/bin:/bin/docker:ro
command: /usr/app/entrypoint.sh
While this allowed me to spin up the container, I was still not able to access to webpage locally.

dbt docs serve by default serves on port 8080. If you want the localdev container's port 8080 to be accessible at 8080 on the host machine, you need:
ports:
- "8080:8080"
You should only list port 8080 once in this list; if you list it alone, without a host port:
ports:
- 8080
Docker will expose it on a random port on the host.
