Docker for Rails Developers

Configuring a Production Environment

Rails pioneered out-of-the-box support for multiple environments. How does this fit in with our Docker setup? We know that our production config will differ from that in development, but what settings do we need and how do we organize things?

Previously, we created the following file structure for our config:

$ tree .env
.env
└── development
    ├── database
    └── web

1 directory, 2 files

Let’s create a copy of our development config as a starting point for our production config:

$ cp -r .env/development .env/production

This should leave us with the following file structure:

$ tree .env
.env
├── development
│   ├── database
│   └── web
└── production
    ├── database
    └── web
