Okay, so I have a question about automatically updating a file that is in a docker, but I think it's more a generic question, not something specific to this docker.

 

And I'm wondering if this approach below works (not sure about the path!) or, should I be doing something else altogether, as it's a docker?!

 

Basically, with the docker binhex-get-iplayer, it has a script which downloads/moves files, but I need it to do this for m4a files, along with the default mp4, so I tweaked a docker script start.sh:

from

 if [[ -n $(find /data/get_iplayer/incomplete/ -name '*.mp4') ]]; then

 

to

 if [[ -n $(find /data/get_iplayer/incomplete/ -name '*.m??') ]]; then

 

Then, assuming this file will get overwritten when the docker updates, I was thinking I could just cron a script to check the contents of this start.sh file, and 'sed' the line to replace the mp4 string each time.

 

But ...

 

the file on the Unraid filesystem is in a "weird" folder, which I'm unsure if it will change or not? I found it here (along with a bunch of other dockers with similar 'long random string directory name':

/var/lib/docker/btrfs/subvolumes/39b661b458331e319abf6b115bf8557821a8429853db56309846bbb6bb976ede/home/nobody/start.sh

 

And, also wondering if there is a better way to make custom modifications to a docker, etc.??

 

thanks

thoughts...

 

docker execute and  user scirpt?

https://docs.docker.com/reference/cli/docker/container/exec/

 

and or add a docker varible and or volume to set a path in the container  -- file replacement...

 

I don't recommend messing with /var/lib/docker/btrfs/subvolumes/

yeah do NOT edit that file, i will have a little think about the best way to achieve this, please can you post a link this in the support thread for the container so i don't forget.

Thanks. Okay so don’t mess with the /var/lib/docker stuff - i hear it.
I took a look at the docker variable for the path, but couldn’t really figure it out, so will leave that alone.

Will keep a track on any changes to this docker to see if there is a permanent solution, else i will just keep on checking the file and editing it manually for now. :)

 

Please use the next docker image and add docker variable to edit the file in docker format to not break host and make edits to use the player.
