Code Review
This pull request addresses several points of feedback from a previous review, improving the quality and clarity of the Cloudron troubleshooting documentation. The changes are generally good, including better command examples, security warnings, and corrected paths. The comments provided further enhance the security aspects of the MySQL connection example by advocating for the use of environment variables for passwords, aligning with best practices for secure tool usage and providing technical justifications for these recommendations.
Note: Security Review has been skipped due to the limited scope of the PR.

With the suggested change to use MYSQL_PWD to provide the password securely, this note about password exposure in the process list is no longer necessary and can be removed for clarity.

- When documenting security practices, explicitly emphasize the preference for secure tools over less secure alternatives. Removing notes that become obsolete due to the adoption of a more secure method implicitly reinforces the preference for the secure approach.

Using the -p flag with a password on the command line exposes the password in the process list, as noted in the comments. A more secure method is to use the MYSQL_PWD environment variable, which the mysql client automatically uses. This avoids exposing the password in the process list and makes the accompanying warnings unnecessary.

| docker exec -it -e MYSQL_PWD="$(cat /home/yellowtent/platformdata/mysql/root_password)" mysql mysql -uroot |
References
- When documenting security practices, explicitly emphasize the preference for secure tools (e.g., gopass) over less secure alternatives (e.g., plaintext files), even if the alternatives are permitted with restrictions. This comment advocates for a more secure method (
MYSQL_PWD) over a less secure one (command-line password). - When documenting restrictions, provide the technical reason behind them to improve understanding. The comment explains that using the
-pflag exposes the password in the process list, providing the technical justification for preferringMYSQL_PWD.

Following the suggestion to use MYSQL_PWD instead of the -p flag, the part of this note about password exposure in the process list is no longer relevant and can be removed.
