Take the time to properly understand Linux file ownership and permission. Permission will be the cause of many issues you will encounter in you self-hosting journey on Linux. Make sure you know the basics of chmod (change permission) and chown (change ownership), Linux users and groups. This will save you some head-scratching, but don’t worry, you will learn by doing !

Remember that, if you setup everything right, especially with docker, running as root / with sudo is not required for any of the services you may want to run.
