What problems have you encountered during deployment in your practice?

During deployment in Golang projects, I often encountered several issues:

• Dependency problems: incorrect version management of modules led to conflicts and build errors.
• Environment configuration issues: lack of a clear configuration management system caused errors when running in different environments.
• Long startup times: especially with large binaries and complex initializations.
• Database migration errors: inconsistency between schema versions and code caused failures.

To address these problems, I used:

• The Go Modules system with fixed versions.
• Configuration management tools (e.g., Viper).
• Optimization of initialization and lazy loading.
• Automation of migrations using specialized tools (e.g., Goose or Flyway).
