[phpMyAdmin Developers] Docker questions

Hi, I'm trying to work on and test the docker container and having some trouble doing local development off of the repository. from my phpmyadmin/docker repository: docker build -t pmadocker . docker run -name mydocker -d -e PMA_ARBITRARY=1 -p 8080:80 pmadocker Trying to log in does give the login page, but it doesn't have the server field. I've also tried with PMA_HOST=192.168.23.1 and it doesn't work, either. Basically, this doesn't seem to pass environment variables (PMA_ARBITRARY or PMA_HOST if I instead specify that). Using the Docker Hub build does work: docker run --name myadmin -d -p 8081:80 -e PMA_ARBITRARY=1 phpmyadmin/phpmyadmin Any idea what I'm doing wrong?
