Don’t clone infrastructure — isolate data: ephemeral PR environments in a shared environment [ukr]

Using a production-proven case of adopting ephemeral PR environments in a single shared cluster, we’ll answer the key questions:

• How to achieve data isolation without cloning the entire infrastructure for every PR;
• Which battle-tested patterns work in 2025: schema-per-env for Postgres, RabbitMQ vhosts/headers, service-to-service tenant headers, third-party webhook metadata (Stripe/Paddle), Temporal tenant context, and the CI/CD lifecycle.

I’ll show practical approaches, common pitfalls, and ready-to-use templates with concise PHP snippets that let you run dozens of parallel features in one cluster, cut costs, and speed up CI.
