Nginx https service

This example creates a basic nginx https service useful in verifying proof of concept, keys, secrets, and end-to-end https service creation in kubernetes. It uses an nginx server block to serve the index page over both http and https.

Generate certificates

First generate a self signed rsa key and certificate that the server can use for TLS. This step invokes the make_secret.go script in the same directory, which uses the kubernetes api to generate a secret json config in /tmp/secret.json.

$ make keys secret KEY=/tmp/nginx.key CERT=/tmp/nginx.crt SECRET=/tmp/secret.json

Create a https nginx application running in a kubernetes cluster

You need a running kubernetes cluster for this to work.

$ kubectl create -f /tmp/secret.json
secrets/nginxsecret

$ kubectl create -f examples/https-nginx/nginx-app.yaml
services/nginxsvc
replicationcontrollers/my-nginx

$ kubectl get svc nginxsvc -o json
...
                    {
                        "name": "http",
                        "protocol": "TCP",
                        "port": 80,
                        "targetPort": 80,
                        "nodePort": 30849
                    },
                    {
                        "name": "https",
                        "protocol": "TCP",
                        "port": 443,
                        "targetPort": 443,
                        "nodePort": 30744
                    }
...

$ kubectl get nodes -o json | grep ExternalIP -A 2
...
                        "type": "ExternalIP",
                        "address": "104.197.63.17"
                    }
--
                        "type": "ExternalIP",
                        "address": "104.154.89.170"
                    }
...

$ curl https://nodeip:30744 -k

Overview

A small script that converts the given open ssl public/private keys to a secret that it writes to stdout as json. Most common use case is to create a secret from self signed certificates used to authenticate with a devserver. Usage: go run make_secret.go -crt ca.crt -key priv.key > secret.json
