Docker Friendly

[Jmilesy]

Is it possible to have the file structure more Docker Friendly?

so have the Data and setting/config files in a subfolder so that they can be stored outside the docker image?

Would symbolic links work for you?

[Jmilesy]

to be honest, i am not sure

For example, if the config folder was in the cumulus folder, it could actually be stored outside the container, and docker could reference the external folder.

for example, as it is Cumulus.ini is stored in the main folder and would be wiped as soon as the container was updated or rebuilt.

Yep, I get where you're coming from. So if you stored the ini file (and the data and backup folders) outside the image and had symbolic links to the locations from inside your docker image then when you tear down and stand up your container the symbolic links (being part of the image) should allow MX to access the untouched configuration and data/backups.

basically, but docker deals with all of that for you.

it is just easier to set up with the config and data as a seperate folder, then you can point it at the folder.

I don't use docker, but I use sym links to place all the temporary files and realtime.txt etc on a ram drive to save disk wear on my rPi. A sym link for the config file should work fine and as Cumulus.ini is not part of the Cumulus distribution it would be be overwritten by updates either.

Moving the config file is possible but it low priority and would go on a very long to-do list.

it sounds like the symlink will work, as this could be set up outside the docker file, it would just need to set up the links to those files on the docker.

the entire container is rewritten so the config file is deleted from within it, so a remote symlink should work too.
