Docker Deploy on VPS: Nginx Strategies for Zero Downtime A late shipment report from a production ERP system was consistently missing. It took three days to find the cause. Unexpected disruptions like this can be frustrating, especially when they occur in live systems. We need to consider similar sensitivities when deploying new versions of our Docker containers running on a VPS. Our goal is to make the updated version of the application available to users without interrupting the existing service. This leads us to powerful reverse proxy solutions like Nginx. We use Nginx not just as a web server, but as a critical orchestration tool in our live deployment processes. Especially with containerized applications, intelligently managing traffic during new version rollouts allows us to achieve our zero-downtime objective. In this post, I'll explain how I implement zero-downtime deployment strategies for our Dockerized applications on a VPS using Nginx.…
