I build my dev and prod environments using the same scripts with just a few changes. To make the two match closer, dev is just a vagrant vm. It works great and I’ve never been tempted to change. If I wanted to run micro services, docker might be nice, but I’m told that microservices are really unpleasant to work with in the long run Some other commenters are taking about problems with dependencies and your production environment getting config drift without docker - this need never happen if you just use scripts to build your environments and never modify your servers manually, always do it via updating your scripts in vc. That’s just infrastructure as code, it doesn’t need docker. A few bash scripts and environment variables can do the same job
