Day 03

Introduction

Using cp, curl, jq

Prerequisites

Challenge

Challenge 1

Copy the Dockerfile from Day 2 with cp

cp ../Day-02/Dockerfile .
cp ../Day-02/main.go .

Challenge 2

Change main.go so we have a json file to request

vi main.go

Change the function handler to the following content

func handler(w http.ResponseWriter, r *http.Request) {
    
    json := `[
        {
            "Path": "interfaces/interface[name=Ethernet1]/subinterfaces",

                    }
                }
                ]
            }
            }
        },

    fmt.Fprintf(w, "%s", json)

}

Start the Server again 
sudo docker build -t json-server . 
docker run -d -p 8080:8080 json-server

Challenge 3

Now get the JSON data from the server

curl localhost:8080

Next format the JSON data, so it looks presentable with jq

curl localhost:8080 | jq

Challenge 4

At last get all of the path from the JSON data or if you want it harder get the interface name from the path.
