No Unpredictable Errors in Reverse Proxy and Deployment

Docker-Blue-Green-Runner's run.sh script is designed to simplify deployment: "With your .env, project, and a single Dockerfile, simply run 'bash run.sh'." This script covers the entire process from Dockerfile build to server deployment from scratch.
In contrast, Traefik requires the creation and gradual adjustment of various configuration files, which can introduce the types of errors mentioned above.
