Docker Parameters question

[gsg-git]

Hello iam preparing additional documentation including an Example.

So could you tell me which variables get a -v an which an -e.
what i guess it could be almost everything
What i have is:
-e Postgres variables
-v flatnode file
-e PBF_URL
-e REPLICATION_URL
-e Wikipediaimport
-v nominatim-data path (PostgreSQL) <----------------------------(so it is possible to run nominatim in a container and the DB locally?)
Flatnode Question of docu:
There it states, that you use a bindmount is it somethink like a Mount to a Folder outside of Docker?
If yes whats the diffrence betrween having the file just in docker?

--shm-size configures the Docker tmpfs i read this is a shared folder between the local system and the Container, but which function does this tmpfs have in the import?

Thank you!

Today the replication update und recheck interval where the ones i think i didnt get:
The REPLICATION_UPDATE_INTERVAL is for setting the interval of updates which where given from where the replication url is so with this interval i set the time the Nominatim installs updates(?)
And the REPLICATION_RECHECK_INTERVAL ist the interval for looking for aviable updates(?)
if yes is the check vor updates seems unnecessary to me(?)

Thank you!

Today i was curios and used printenv in the Container and there was everything i used in the docker run.
Can i change any settings via this systemvariables?
Thank you!

I now have at least an idea, why you would use a local flatnode file and database:
To ease installing updates
