Docker-compose

I advise you to use docker-compose, which is a great tool for managing containers. You can create a docker-compose.yml with the following content (which must be adapted to your needs) and then run docker-compose up -d nextcloud-db, wait some 15 seconds for the database to come up, then run everything with docker-compose up -d, that's it! On subsequent runs, a single docker-compose up -d is sufficient!

Port

• 8888 : HTTP Nextcloud port.

IP

• IP : Nextcloud server ip address. to find ip address of your nextcloud server docker inspect DOCKERIMAGE | grep IPAddress | grep -Eo '[0-9.]+' | head -n1

Docker-compose file

Don't copy/paste without thinking! It is a model so you can see how to do it correctly.

    - nextant

# If using Redis
redis:

You can update everything with docker-compose pull followed by docker-compose up -d.

Reverse proxy

I use nginx on the host machine. Headers are already sent by the container, including HSTS, so there's no need to add them again. It is strongly recommended to use Nextcloud through an encrypted connection (HTTPS). so if you're using nginx, below is the configuration.

server {
  listen 8000;
  server_name example.com;
  return 301 https://$host$request_uri;
}

server {
  listen 4430 ssl http2;
  server_name example.com;

  ssl_certificate /certs/example.com.crt;
  ssl_certificate_key /certs/example.com.key;

  include /etc/nginx/conf/ssl_params.conf;

  client_max_body_size 10G; # change this value it according to $UPLOAD_MAX_SIZE

  location / {
    proxy_pass http://nextcloud:8888;
    include /etc/nginx/conf/proxy_params;
  }
}
