Offline Installation - sourceforge download

Hello @grumo
I’m not sure that I understand your whole installation steps, but I assume that the best way to deploy Document server on the server without access to Internet is the docker installation. Could you please follow and check the result?

  1. Download image with ONLYOFFICE Document Server from the official repository from the DockerHub on a server with Internet access using command:
    sudo docker pull onlyoffice/documentserver
  2. Save image as files with the command:
    sudo docker save -o documentserver.docker onlyoffice/documentserver
  3. Transfer image file to a machine without Internet access and deploy them as Docker images with the command:
    sudo docker load -i documentserver.docker
    More information can be found in the article at the link (offline files - Downloading docker image for transfer to non-internet-connected machine - Server Fault).
  4. Execute following command to run a new Docker container with Document Server:
sudo docker run -i -t -d -p 80:80 -p 443:443 --name=onlyoffice-document-server --restart=always \
    -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data  \
    -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
    -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql  onlyoffice/documentserver
