Deploy your MySQL app to Fly.io
Step-by-step deployment help for MySQL apps on Fly.io. We fix MySQL-specific deployment issues, configure Fly.io, and get your app live. From $19.
MySQL issues we fix before deploying
Common MySQL problems that affect Fly.io deployments.
SQL injection vulnerabilities
String concatenation used to build queries instead of parameterized statements, allowing attackers to read, modify, or delete data.
Missing database indexes
Tables without indexes on columns used in WHERE, JOIN, and ORDER BY clauses, causing full table scans as data grows.
No connection pooling
Opening a new database connection per request instead of using a connection pool, exhausting MySQL's max_connections limit under load.
Credentials in source code
Database host, username, and password hardcoded in application files or committed to version control.
Fly.io deployment issues we check for
Common Fly.io problems that break MySQL apps in production.
Dockerfile missing or misconfigured
Fly.io requires a Dockerfile for deployment. AI tools that scaffold without one force flyctl to auto-generate a suboptimal Dockerfile that misses build steps.
Volume only available in a single region
Fly volumes are pinned to one region. Multi-region deployments try to access a volume that doesn't exist in other regions, causing crashes.
Machine restarts losing in-memory state
AI-generated apps store session data or caches in memory. Fly machines can restart or migrate, wiping all in-memory state without warning.
Internal DNS resolution failing between services
Services within a Fly organization communicate via <app>.internal hostnames, but AI-generated code hardcodes localhost or public URLs.

Frequently asked questions
How do I deploy a MySQL app to Fly.io?
We handle MySQL deployments to Fly.io end to end. Start with our code audit ($19) to identify deployment blockers specific to your MySQL project, then we configure Fly.io, fix issues, and get your app live in production.
What MySQL issues affect Fly.io deployments?
MySQL projects commonly have sql injection vulnerabilities and missing database indexes. On Fly.io, these combine with dockerfile missing or misconfigured and volume only available in a single region to cause deployment failures.
Can SpringCode deploy my MySQL project to Fly.io?
Yes. We specialize in deploying MySQL applications to Fly.io. We audit your codebase for MySQL-specific issues, configure Fly.io correctly, and handle the full deployment so your app runs reliably in production.
What does MySQL deployment to Fly.io cost?
Our code audit ($19) identifies all Fly.io deployment blockers in your MySQL project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
