Volumes in Docker

[cairoapcampos]

I found the link below on how to create volumes for webvirtcloud:

https://www.nodinrogers.com/post/2021-12-30-webvirtcloud-in-a-docker-container/

Is this the best way to create volumes in a production environment?

I've already made some changes locally that have comments in bold. See the docker file below.

Some doubts:

1° Is it possible to change the script webvirtcloud/conf/runit/secret_generator.py not to generate keys that have quotes?

2° Is it possible to run the container with a non-root user?

"1° Is it possible to change the script webvirtcloud/conf/runit/secret_generator.py not to generate keys that have quotes?"

• it is done. i will upload new version of this generator. it generates urlsafe(without quota) secrets.

we especially did not automate settings.py modification. some user may want to use mysql/postgresql instead of "db.sqlite3"... volumes also related with this situation.

This question can be closed.

I'll try the tip in the link to see if it's possible to use a non-root user:

Thanks for changing the script webvirtcloud/conf/runit/secret_generator.py.
