I’m attempting to install nextcloud docker on my Synology 923+ inside portainer.
When I create the instance without redis in my docker compose file I can bring up the nextcloud app without issue. The same is true if I add the redis portion to my compose file, but exclude the
REDIS_HOST env from the nextcloud service. However, once nextcloud attempts to use redis as the session handler the nextcloud site will spin until it times out.
After many hours of troubleshooting I think I’ve found the issue, but can’t figure out a fix. I have confirmed the redis server is up. Unfortunately ping is not installed with the nextcloud docker, but using /dev/tcp I’ve established that the nextcloud container cannot ping the redis container. This the db container which is on the same network as the redis and nextcloud containers can ping without issue.
Here is my docker-compose.yml:
version: '3' services: db: image: mariadb:10.6 restart: always command: --transaction-isolation=READ-COMMITTED --log-bin=binlog --binlog-format=ROW --innodb-read-only-compressed=OFF volumes: - /volume1/docker/nextcloud/database:/var/lib/mysql environment: - MYSQL_ROOT_PASSWORD_FILE=/run/secrets/mysql_root_pw - MYSQL_PASSWORD_FILE=/run/secrets/mysql_pw - MYSQL_DATABASE_FILE=/run/secrets/mysql_db - MYSQL_USER_FILE=/run/secrets/mysql_user - MARIADB_AUTO_UPGRADE=1 - MARIADB_DISABLE_UPGRADE_BACKUP=1 secrets: - mysql_db - mysql_user - mysql_pw - mysql_root_pw nc-redis: image: redis:5 restart: always volumes: - /volume1/docker/nextcloud/redis:/data expose: - 6379 app: image: nextcloud restart: always ports: - 8080:80 volumes: - /volume1/docker/nextcloud/config:/var/www/html environment: - MYSQL_PASSWORD_FILE=/run/secrets/mysql_pw - MYSQL_DATABASE_FILE=/run/secrets/mysql_db - MYSQL_USER_FILE=/run/secrets/mysql_user - MYSQL_HOST=db - REDIS_HOST=nc-redis secrets: - mysql_pw - mysql_db - mysql_user depends_on: - db - nc-redis secrets: mysql_user: file: /volume1/docker/vars/mysql_user.txt mysql_db: file: /volume1/docker/vars/mysql_db.txt mysql_pw: file: /volume1/docker/vars/mysql_pw.txt mysql_root_pw: file: /volume1/docker/vars/mysql_root_pw.txt redis_pass: file: /volume1/docker/vars/redis_pw.txt nc_user: file: /volume1/docker/vars/nc_user.txt nc_pw: file: /volume1/docker/vars/nc_pw.txt
Unfortunately all the logs I’ve been able to find have been useless.
Does anyone have any ideas?
Thanks in advance.
