[Help] Folder settings for docker container [SOLVED]

[jnbixler]

Hi, quite new to Docker and to TOS6, and have a question about best practices for file locations; I am trying to set up a container for Kopia, I found an image and downloaded it, and now looking at the installations settings here:

https://kopia.io/docs/installation/#docker-images

Apparently I need to mount a number of local volumes, like so:

Code: Select all

# Mount local folders needed by kopia
            - /path/to/config/dir:/app/config
            - /path/to/cache/dir:/app/cache
            - /path/to/logs/dir:/app/logs
            # Mount local folders to snapshot
            - /path/to/data/dir:/data:ro
            # Mount repository location
            - /path/to/repository/dir:/repository
            # Mount path for browsing mounted snaphots
            - /path/to/tmp/dir:/tmp:shared

My question is, what would be the preferred location to mount these (aka the "/path/to/config/dir:)? Would it be my user home folder, or somewhere else? As a side note, I'm a little confused on the role of the home folder in TOS - I always thought it was for keeping personal files, but I read in another comment that it's not intended for data storage. What is it meant to be used for?

Appreciate any advice!

Hello, sorry for the delay. Here are the answers to your questions:

1.Regarding the script’s mount directories:
The script does have default mount paths (e.g., /app/config, /data). These are already optimized for the Kopia container, and there’s no need to reselect alternative locations unless you have specific requirements.
2.Regarding the /home directory:
While the /home directory can store data, its primary purpose on a multi-user NAS is to host personal directories for each user (e.g., /home/user1, /home/user2). This is because the NAS supports multiple users and needs a dedicated space to store their personal data—that’s the role of /home.

Hi, thanks for getting back to me!

1. Sorry, I'm still a little confused, don't I need to specify a root directory for those paths? "/path/to/config/dir:/app/config" wouldn't work as-is, right? Would it be something like "homes/[myusername]/docker/kopia/app/config"?

2. Thanks, that makes sense! I didn't realize you could set up a new share folder within the user directory.

The specific path configuration for mount directories can be flexibly set by users according to their actual requirements. Although Docker image authors may pre-define recommended mount paths in the base configuration (such as /var/lib/mysql for database data and /etc/nginx/conf.d for configuration files), as a container user, you have full authority to override the default mount points and extend your mounting needs as necessary.

Got it, I think I got it working... Thanks for the help!

The home directory on TOS is typically reserved for storing files and configurations related to your user account on the TOS system (e.g. application configurations, personal files you upload via the TOS user interface).

Don’t use /home/username or your user folder unless you’re experimenting. And always mount folders with the correct permissions (ro for read-only, shared if needed).
