The issue is resolved. Two things fixed this. Since my nginx.conf contained a 443 server, I had to comment that out. And, also I added restart: to my nginx service in my docker compose. I deleted my local certbot folder (all contents) and then reran my script with all my 443 config commented out. This time just the nginx started (executed from the docker-compose.yml) from the init-letsencrypt.sh script.
Sorry for the post.
