Provided detailed commands to backup and upgrade Rustdesk

[juanchomang]

I expanded on the commands to provide more detailed instructions on how to perform a backup of Rustdesk as well as bringing down the docker containers, removing the containers, removing the images, pruning any unused images, and finally pulling and bringing back up a fresh image of Rustdesk docker container.

changed:
docker kill

for a more gentle:
docker stop

[rustdesk]

Coud you confirm if below better If docker compose up -d --build --pull always does not work for you？

docker compose down
docker compose pull 
docker compose up -d

Your commands work, but it is not a docker compose way. :(

[juanchomang]

Sure, that works for upgrading but it does not clean up unused images.

[rustdesk]

docker compose down
docker rmi rustdesk/rustdesk-server-pro  
docker image prune -f 
docker compose pull 
docker compose up -d

Will work?

[juanchomang]

Yes, that would work very well.

[rustdesk]

Interesting, the pull does not overwrite old image? The old image is not removed? How does it look like with docker images?

[juanchomang]

I will try at the next version upgrade as it is not possible to replicate the environment now that I have upgraded... I even tried to pull an older image but the tag doesn't match so it won't overwrite...

[juanchomang]

I will try this:

docker compose down
docker compose pull
docker compose up -d

[rustdesk]

Thanks, great.

[xlionjuan]

docker compose pull
docker compose up -d

This will reduce downtime. The first command pulls the new image; the second command switches to the new image and recreates the container without having to wait for the pull process (though both RustDesk OSS and Pro server images are small).

After Docker switches to the new image, the old one becomes a "dangling image" (unused). Users should remove it themselves if needed.

We should not suggest users run this command, as they may be unfamiliar with Docker and risk causing data loss. We shouldn't have to take this responsibility.

docker image prune -f
