Better Documentation on how to upgrade to new version (server, docker-compose)

[TheNomad11]

Trilium is the most impressive app I have encountered but documentation could be better, especially regarding upgrading for us who are no sysadmins and still learning. Currently the only available information for the recommended docker setup is:

for docker server installation - pull the image of the newer version and restart

In the past, this did not work for me, I only got error message, therefore I was looking for a docker-compose file. After some searching I found a working one, now I did the standard docker-compose stop, docker-compose pull, docker-compose up -d but then it seemed my Trilium instance got wiped out, the first set-up screen appeared. It seems there have been upgrade issues before, see #1747, EDIT: also related to unresolved issue #1971

So what is the recommended way to update?

And: Is using a docker-compose file recommended or not?

My docker-compose file:

version: '2.1'
services:
  trilium:
    image: zadam/trilium:latest
    user: root
    restart: always
    environment:
      - TRILIUM_DATA_DIR=/root/trilium-data
    ports:
      - "6080:8080"
    volumes:
      - /home/USER/trilium/trilium-data:/home/node/trilium-data

Thanks!

(Will now try to restore from backup)

EDIT: Backup was not saved in data folder, I experimented with permissions and changed data folders, nothing worked, so some permission issues it seems

EDIT 1: This solution worked for me #1747 (comment)
But the data directory is not as it shown in the backup section at /home/node but under root

Remember this:

volumes:
  - Host directory:Container directory

You've changed the default note storage directory to /root/trilium-data in Container by setting environment variable TRILIUM_DATA_DIR. So your volume mapping should be like:

volumes:
  - /home/USER/trilium/trilium-data:/root/trilium-data

The last part, which is the Container directory, should be the same as the directory you set in the TRILIUM_DATA_DIR.

Thanks for helping me to understand docker.compose better! I will try again.
Nevertheless I think it is necessary to update the documentation
