It is not advisable.
Do not touch your production setup until they pass on your test and staging instance.
If you use frappe_docker you can create a second bench where you can do the install.
Actually Docker is a very technical for me to understand and modify.
And I feel that attachment uploading is very very slow when ERPNext is running in Docker container.
That is why I am thinking of installing latest version of ERPNext manually following various tutorials that are already available in this forum.
But what I need to understand is that it is advise able to install Frappe Bench outside the Docker Container when one is already running inside a Docker Container?
If installed will it interfere with already running docker image of ERPNext?
