 8 | ## 1. Get dependencies
 9 | 
10 | We only have one dependency, so let's get it and vendor it:
11 | 
12 | ```sh
13 | docker run --rm -v "$PWD":/app -w /app iron/node:dev npm install
14 | ```
15 | 
16 | ## 2. Test it locally
17 | 
18 | ```sh
19 | docker run --rm -it -p 8080:8080 -v "$PWD":/app -w /app iron/node node server.js
20 | ```
21 | 
22 | Check localhost:8080 to ensure it's running.
23 | 
24 | ## 3. Build image
25 | 
26 | ```sh
27 | docker build -t treeder/tiny-node:latest .
28 | ```
29 | 
30 | ## 4. Test the image
31 | 
32 | Now that we built the image, let's run it.
33 | 
34 | ```sh
35 | docker run --rm -it -p 8080:8080 treeder/tiny-node
36 | ```
37 | 
38 | Surf to: http://localhost:8080/
39 | 
40 | Boom.
41 | 
42 | ## Fat version
43 | 
44 | To build the fat version, change all the iron/node bits to node:argon.
