World Deleted? After Update

[Borderman2]

Hello, it's me again today we where playing on the server and we lost connection to it assuming it was a another chrash but the server didn't come back on the network.

i assume that the network connection got cut. the server continued to functiond normal (without connection). after the auto restart from the server it couldn't connect to steam and tried a few times to establish a connection, when the connection finally came back steam made an update. and now the "instances" folder is empty.

can you help out?

Logs.txt

sorry that the logs are in a txt file otherwise it would have looked bad (and im lazy to format). those are the last surviving logs.

best regards 2B.

Hey, how do you run the image? I mean how did you connect the "instances" folder? Do you use volumes, or do you use host directories?

[Borderman2]

Hey, Whatever comes as default is what i am are using. im not a expert with docker containers so if you mean mounting a directory or setting a WORKDIR i have not done that.

best regards 2B.

If you start it with "docker run" let me know your full starting command and if you run with a composer file let me know its contents please.

in the folder where i have downloaded the docker i use docker-compose up -d to start it. i use docker container ls to list if its there and docker container logs -f se-ds-docker to see its logs.

and this is the content of the docker-compose file.

version: '3.8'

services:
  se-server:
    build: .
    image: spaceengineers:latest
    container_name: se-ds-docker
    restart: unless-stopped
    volumes:
      # left side: your docker-host machine
      # right side: the paths in the image (!!do not change!!)
      - /appdata/space-engineers/instances:/appdata/space-engineers/instances
      - /appdata/space-engineers/SpaceEngineersDedicated:/appdata/space-engineers/SpaceEngineersDedicated
      - /appdata/space-engineers/steamcmd:/root/.steam
    ports:
      - target: 27016
        published: 27016
        protocol: udp
        mode: host
    environment:
      - WINEDEBUG=-all
      - INSTANCE_NAME=SpaceServer
      - PUBLIC_IP=127.0.0.1
      # public ip required for healthcheck

Ok, if you use this file, your instances folder should never be cleared at all by the image. Could anything on your host-machine delete the folder?

My idea was that you use docker-volumes instead of host links, that might lead to empty folders maybe but in your case it might be host related issue.

i was going to answer but git went down ... anyway everything else was fine but space, is it possible to store the world in the home directory?

[Devidian]

sure, you can change the left part of volumes to whatever you want.

[Borderman2]

i m looking at the documentation and if im understanding it correctly i need to add volumes: - myapp:/home/SE/ but what doese myapp stand for?

im not an expert with docker containers. if you could help out that woud be very appreciated.

One way is to change the left side like this:

version: '3.8'

services:
  se-server:
    build: .
    image: spaceengineers:latest
    container_name: se-ds-docker
    restart: unless-stopped
    volumes:
      # left side: your docker-host machine
      # right side: the paths in the image (!!do not change!!)
      - /home/SE:/appdata/space-engineers/instances
      - /appdata/space-engineers/SpaceEngineersDedicated:/appdata/space-engineers/SpaceEngineersDedicated
      - /appdata/space-engineers/steamcmd:/root/.steam
    ports:
      - target: 27016
        published: 27016
        protocol: udp
        mode: host
    environment:
      - WINEDEBUG=-all
      - INSTANCE_NAME=SpaceServer
      - PUBLIC_IP=127.0.0.1
      # public ip required for healthcheck

Another way is to add a docker volume like this: see documentation

version: '3.8'

services:
  se-server:
    build: .
    image: spaceengineers:latest
    container_name: se-ds-docker
    restart: unless-stopped
    volumes:
      # left side: your docker-host machine
      # right side: the paths in the image (!!do not change!!)
      - instancesVolume:/appdata/space-engineers/instances
      - gameVolume:/appdata/space-engineers/SpaceEngineersDedicated
      - steamVolume:/root/.steam
    ports:
      - target: 27016
        published: 27016
        protocol: udp
        mode: host
    environment:
      - WINEDEBUG=-all
      - INSTANCE_NAME=SpaceServer
      - PUBLIC_IP=127.0.0.1
      # public ip required for healthcheck
volumes:
  instancesVolume:
  gameVolume:
  steamVolume:

ok thank you, sad that the world is lost but now we can at least make an script that saves the current backup folder and zip it.
