Hello everyone !
I am trying to run nextcloud in Docker containers but I need a production deployment. So, I can’t use only docker-compose for production and I need to use Swarm.
This is my docker-compose file :
version: ‘3’
services:
proxy:
image: jwilder/nginx-proxy:alpine
labels:
- “com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy=true”
container_name: nextcloud-proxy
networks:
- nextcloud_net
- nginx_net
ports:
- 80:80
- 443:443
volumes:
- ./proxy/conf.d:/etc/nginx/conf.d:rw
- ./proxy/vhost.d:/etc/nginx/vhost.d:rw
- ./proxy/html:/usr/share/nginx/html:rw
- ./proxy/certs:/etc/nginx/certs:ro
- /etc/localtime:/etc/localtime:ro
- /var/run/docker.sock:/tmp/docker.sock:ro
db:
image: mariadb
container_name: nextcloud-mariadb
networks:
- nextcloud_net
volumes:
- db:/var/lib/mysql
- /etc/localtime:/etc/localtime:ro
environment:
- MYSQL_ROOT_PASSWORD=OpenSource2020!
- MYSQL_PASSWORD=LesDBavantlesputes!
- MYSQL_DATABASE=nextcloud_db
- MYSQL_USER=nextcloud_db_user
app:
image: nextcloud:latest
container_name: nextcloud-app
networks:
- nextcloud_net
depends_on:
- proxy
- db
volumes:
- nextcloud:/var/www/html
- ./app/config:/var/www/html/config
- ./app/custom_apps:/var/www/html/custom_apps
- ./app/data:/var/www/html/data
- ./app/themes:/var/www/html/themes
- /etc/localtime:/etc/localtime:ro
links:
- db
environment:
- MYSQL_PASSWORD=mysqlpassword
- MYSQL_DATABASE=nextcloud_db
- MYSQL_USER=nextcloud_db_user
- VIRTUAL_HOST=myserver.mydomain
- LETSENCRYPT_HOST=myserver.mydomain
- LETSENCRYPT_EMAIL=mail@mydomain
- NEXTCLOUD_HOSTNAME=myserver.mydomain
- NEXTCLOUD_ADMIN_USER=admin
- NEXTCLOUD_ADMIN_PASSWORD=admin
volumes:
nextcloud:
db:
networks:
nextcloud_net:
nginx_net:
When I run it with docker-compose up, everything works well !
I delete all volumes on the disk and do docker system prune --volumes to delete all and restart from scratch.
I create a swarm with :
docker swarm init
I deploy the stack :
docker stack deploy -c docker-compose.yml stack_nextcloud
Yesterday, it worked but I reach this page when I browse my server :
Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.
I wanted to retry today but this time I get something else.
The command docker stack deploy ends with no errors and my 3 services are created (db, app and proxy) but only the db container is created !

What am I doing wrong ?
Thanks
