Error when mount a volume using docker-compose

Question

I'm using docker-compose to setup domserver.I can run the domserver successfully using image of dockerhub.However,when I want to mount a directory into the container,it will pop error message like this:

dj-domserver_1  | /scripts/start.sh: line 29: cd: /opt/domjudge/domserver: No such file or directory

the directory domjudgeKChen is cp from the container that is setup by the image of dockerhub (domserver6.0.3) this is the domserver part in yml file:

dj-domserver:
                image: domjudge/domserver:6.0.3
                volumes:
                        - /sys/fs/cgroup:/sys/fs/cgroup:ro
                        - ~/domjudgeKChen/opt/domjudge:/opt/domjudge
                environment:
                        - CONTAINER_TIMEZONE=Asia/Taipei
                        - MYSQL_ROOT_PASSWORD=rootpw
                        - MYSQL_DATABASE=domjudge
                        - MYSQL_USER=domjudge
                        - MYSQL_PASSWORD=djpw
                networks:
                        dj-db:
                        dj-judgedaemons:
                depends_on:
                  - phpmyadmin
                  - dj-mariadb
                ports:
                        - 9090:80
                links:
                        - dj-mariadb:mariadb
                restart: always

and this is the entire.yml file code:

The other question is that I can't setup the judgehost using this yml file.This is the error message when using docker-compose up

error: Authentication failed (error 401) while contacting http://domserver/api/v4/judgehosts. Check credentials in restapi.secret.

If I comment out line 22 in the yml and the domserver can setup using docker-compose up and the mariadb,phpmyadmin would also be fine.

please help me mount the directory into the container and setup the judgehost image successfully.Thanks!

Answer 1

IIRC you must use absolute references for your volumes; you can't use ~ .

Replace ~ in the volume mount with the absolute path and prefix that to /domjudgeKChen/opt/domjudge in your volume definition.
