Start with one service
Choose a tool you can understand and maintain. Read its requirements, update process and backup instructions before deployment. Expanding a dependable setup is easier than rescuing a collection of abandoned experiments.
Use maintained components
Select supported images and packages, verify their source and track releases. Pin versions deliberately while keeping a routine to evaluate updates. An old container can remain vulnerable even when the host operating system is current.
Plan identity and recovery
Protect logins, keep recovery codes privately and make sure account access does not depend on the same service that has failed. A password manager or mail service needs particular care because other recoveries may depend on it.
Keep it rebuildable
Record the configuration and back up persistent data. Test the restore on a separate machine. A clear rebuild procedure turns a failure from an improvised emergency into a bounded maintenance task.
