Docker-compose setting problem about Domjudge server - docker

Question

I want to build a domjudge server with mriadb, phpmyadmin, judgehost in the docker base on Debian9,
I've install the docker and docker compose
here is the docker-compose.yml code below.
and I use docker-compose up -d and there are some WARNING and ERROR pop out.
here is the entire docker-compose.yml file code
http://codepad.org/souBFdFz
WARNING and ERROR messages:
WARNING: some networks were defined but are not used by any service: phpmyadmin, dj-judgedameons_1, dj-judgedameons_2
ERROR: dor domjudge_dj-judgedameons_2_1 Cannot start service dj-judgedameons_1 : OCI runtime create failed: container_linux.go:345: starting container process caused "process_linux.go:311:getting Starting domjudge_dj-judgedameons_1_1
...and a lots of error messages that I cant even read(binary code or address i think)
Please help me fix it or if there is a easy way to set up domjudge server with mariadb, phpmyadmin, judgehost
THANKS!
Update
I've tried this file several times and it has a drifferent result but it still can't connect to the server (domjudge & phpmyadmin).
here is the message

Unfortunately what you want to do is not really possible because of how the application is built: containers need to wait for each other and some of them need manual actions.
However, this is a sequence of actions that works and will bring all containers up and running.
NOTE: I removed the networks declarations because they don't add any value.

Start the database and wait for it to initialize (otherwise the server will exit because it cannot find the schema it needs)
docker-compose up -d dj-mariadb
Start the server:
docker-compose up -d dj-domserver
Get the admin password from the logs:
docker-compose logs dj-domserver
Look for the line saying: Initial admin password is .... and save the password.
Set the judgehost password in the web interface: open http://localhost:9090 and login with user admin and the password you saved from the previous step. Go to Users and click on judgehost user. In there change the password to domjudge (according to what you set in the docker-compose.yml for JUDGEDAEMON_PASSWORD. Save the data.
Start the rest of the containers:
docker-compose up -d
Verify that all containers are up and running:
docker-compose ps
Output should look similar to this:
