Configured Docker-Bind/Path is empty, can't backup Files

[Noah0302]

Hello everyone,

Ive run into an issue not being able to backup the Config-Files of my pawelmalak/flame Container, since the path I configured a while back seems to be empty:

noah@flamedashboard:~$ ls /vw-data
noah@flamedashboard:~$ ls -a /vw-data
.  ..

I have not noticed this for Months, since I was able to configure the Dashboard via the Webinterface, with the Changes being persistent between Reboots of the Host and stopping of the Container.
Updating the Container resulted in it being reset to the default Config, so I just restored a Snapshot for now, thats also when I noticed that something was wrong.

Here is a Sample of the Output when inspecting the running Container:

Try 

docker exec <container> /bin/ls /data

Does it show the files you’re looking for ? If no, verify that you’re mounting in the correct path

Sorry for the late reply!

I created the Container like that initially:

docker run -d --name=flamedashboard -e TZ=Europe/Berlin -p 80:5005 -v /vw-data/:/data/ -e PASSWORD=PWHERE --restart unless-stopped pawelmalak/flame

However I realized just now, that I misconfigured the Command. I put

/vw-data/:/data/

instead of

/vw-data/:/app/data

This way it was an invalid Mount and it just stored the Files somewhere else...

 

 

 

Your provided Command did show me the Files I was looking for, just had to remove the "/" before "/data".
Now I knew that the files are present on the Filesystem.

 

 

 

I found them by searching for all Folders named "data" with the following Command:

sudo find / -type d -name "data"

And then navigating to the path that included the correct Container-ID.
There I was able to just ZIP the files and download them via SFTP.

 

 

Thank you for the Input!

This is because the container’s Dockerfile will have the statement “Workdir /app”, meaning if you perform `ls data`, that’s equivalent to performing `ls /app/data`
