We are in the process of migrating our blog away from Wordpress.com and on to railway.com, everything is currently working, however, after a deployment a few hours ago, there appear to be 2 docker containers running on our production deployment architecture, even though we only specify 1 to be running. When we remove the oldest deployed wordpress container, it successfully appears removed, but then a few minutes later it returns. 

I've attached a screen shot.

We are also hosting our wordpress site at a subdir which means the content is moved to /var/www/html/blog, but if we trigger redeployment, although are files are still present, the deployment adds another wordpress install at /var/www/html is it possible to stop that happening, is there a feature to snapshot an existing architecture into a private template or something?

Thanks
