Hello, 

I have successfully connected to my Unraid SSH as I usually do, then figured out how to bash into a docker container to list the files of the root of that container
 

docker exec -it dockercontainername /bin/bash

I can then 'ls' to see the files I want to copy or move to either 
01. a location on the UnRAID array - eg. /mnt/cache
02. the windows system I am on

I can't figure out how to copy the file so I can gain access to it. Does anyone know the method to do this
I tried some cp commands and scp commands and have not been successful

I don't really want to have to do a hexdump and piece this together, there has to be a way to get content out of the docker container and back into another container

Im not talking about the containers on appdata/cache/dockerimagename
talking about the files within the docker container itself

Thank you,

EDIT
After hunting and searching I was able to successfully figure out how to

 

• connect to docker container
• sudo and nano within docker
• copy files from docker container to unraid
• copy files from unraid to docker container(s)

 

 

How to connect to docker container:

docker exec -it contaidername /bin/bash

ls -l

To find the files or paths that need to be accessed for the copy command

 

exit

 

Add sudo & nano within docker container:

Sudo:

root@dockercontainerID# apk add sudo

(1/1) Installing sudo (1.9.10-r0)
Executing busybox-1.35.0-r17.trigger
OK: 279 MiB in 80 packages

 

Nano:

root@dockercontainerID:/# apk add nano
fetch http://dl-cdn.alpinelinux.org/alpine/v3.16/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.16/community/x86_64/APKINDEX.tar.gz
(1/1) Installing nano (6.3-r0)
Executing busybox-1.35.0-r17.trigger
OK: 277 MiB in 79 packages

 

How to copy files from docker container to UnRaid server:
 

root@servername:~# sudo docker cp containername:/filename.xxx ~/file path on unraid

-OR-

root@servername:~# sudo docker cp containername:/filename.xxx /file path on unraid

EXAMPLE:

root@servername:~# sudo docker cp mariadb:/filename.txt ~/mnt/cache/

 

How to copy files from Unraid server to docker container:
 

root@servername:~# sudo docker cp /unraid/location/123.txt containername:/

 

EXAMPLE::

root@servername:~# sudo docker cp /mnt/cache/123.txt mariadb:/

Hope that helps someone going down the same path as me tonight

 

Cheers!
