Can you rollback a database migration with Deploynix?

No. Rollback only reverts code. If your broken deployment ran migrations, you need to handle database rollback separately — either by writing a reverse migration or by restoring from backups. This is the biggest limitation of any rollback system and why careful database testing is non-negotiable.

What happens to in-flight requests during a rollback?

Nginx instantly starts serving the old code from the rolled-back release. Requests that are already in-flight may hit the new code briefly, but all new requests go to the old code. It's not a graceful drain-and-switch — it's instantaneous. For most applications this is fine, but services with very long-running requests should be aware.

How many old releases does Deploynix keep on disk?

It's configurable. You specify how many recent releases to retain, then older ones get deleted to save disk space. This balances rollback flexibility with storage costs. Keeping 10-20 releases is typically enough to cover most disaster scenarios without bloating your server.

Will this actually work with my PHP/Node/Python app?

Deploynix is framework-agnostic. It works with any language or framework as long as you can configure your web server (Nginx, Apache) to serve from the `current` directory. The principles scale everywhere.

The 30-Second Rollback: Why Deploynix's Release Strategy Actually Works (And Why It Matters)

It's 4:47 PM on Friday. Your deployment passed CI, hit production, and immediately broke everything. With Deploynix, you're back to working code in 30 seconds. Here's why symlink-based releases are the closest thing DevOps has to an undo button.

⚡ Key Takeaways

Deploynix uses atomic symlink swaps to enable 30-second rollbacks—far faster than traditional redeployment approaches that can take 5-10 minutes. 𝕏
The release-based architecture keeps previous deployments intact on disk, making rollback a symlink operation rather than a full redeployment, but it doesn't solve database migration failures. 𝕏
Rollback covers code, dependencies, and compiled assets but does NOT undo database schema changes, environment variables, or queued jobs—understanding these boundaries is critical for on-call decision-making. 𝕏
