How to set permissions for samba?

[Giresharu]

Hello, I’m new to Linux and Docker, so there are many concepts that I haven’t had time to fully understand yet.

I’m currently encountering a permissions issue; one of the directories on my Linux does not have write permissions for all users.(since I use my Linux as an HTPC, I must prevent children from modifying important files). Now, after using Samba with this image, although I can access it from other devices, I don’t have permissions to create new folders or write files.

What I want to know is whether I need to grant read and write permissions on Linux to the user that represents Docker, or perhaps the Samba user?

This question might seem silly to a Linux expert, but due to my limited abilities, I don’t know how to break this down into keywords for an online search, so I had to come and file an issue, hoping someone can help me out. Thank you!
