Deployment with Docker

Running it all together

So, we have our web_server, application_server, and database containers all figured out. Let's verify that you have all the files matching these before moving on:

$ tree ..├── application_server│   ├── Dockerfile│   ├── index.js│   ├── package.json│   └── views│       └── index.pug├── database│   └── Dockerfile└── web_server    ├── Dockerfile    └── nginx_main_site.conf4 directories, 7 files

The next step for us is to build all the containers:

 $ # Build the app server image $ cd application_server $ docker build -t application_server . Sending build context to Docker daemon 34.3kB Step 1/10 : FROM node:8 <snip> Successfully built f04778cb3778 Successfully tagged application_server:latest  $ # Build the database image $ cd ../database
