How to connect local private supermarket with local private chef server

Once you have your local supermarket and local chef-server setup you need to follow the following steps in order to connect both.

Chef Server Changes:

  • Go to chef-server repository folder
  • Go to the dev directory:
    • cd dev
  • Spin up the vagrant instance and follow the default instructions given for chef-server setup:
    • vagrant up
  • SSH into the vagrant machine by:
    • vagrant ssh
  • You need to change to sudo user:
    • sudo -i
  • Go to the specific directory as follows:
    • cd /etc/opscode
  • You need to edit the chef-server.rb
    • vim chef-server.rb
  • Register supermarket with oc-id in this file by appending the following configuration:
oc_id["applications"] = {
  "supermarket" => {
    "redirect_uri" => "https://localhost:4000/auth/chef_oauth2/callback"
  • In the above configuration we are saying that once authorized it should redirect to the specified URL. You will note that your supermarket is running at port: 3000 and with protocol: http but here we are setting up the port: 4000 and protocol: https as the chef server is running in https hence it will expect the redirect url to be a https url. We will be running an nginx server which will accept https request at port 4000 and the nginx server will then redirect the request to our supermarket server which will be running at port: 3000 and protocol: http. Check the next steps.

  • Once you have made the modifications to chef-server.rb you need to reconfigure the chef server by the command:

    • chef-server-ctl reconfigure
  • The above command will generate supermarket configuration under the folder /etc/opscode/oc-id-applications

    • Filename: supermarket.json
  • The supermarket.json will contain the client id(uid) and secret token(secret) as follows:

  "name": "supermarket",
  "uid": "<supermarket client id>",
  "secret": "<secret token for supermarket>",
  "redirect_uri": "https://localhost:4000/auth/chef_oauth2/callback",
  "scopes": []
  • You need to take the uid and secret and add both in your supermarket configuration.
  • Check the IP address of the chef-server by the command
    • ifconfig

      Take the value against: eth1. The IP would be something like:

Supermarket Changes

  • Go to the supermarket repo. Then run:
    • cd src/supermarket
  • Modify the .env file and add the generated uid and secret against the parameters:
    • CHEF_OAUTH2_APP_ID: <uid>
    • CHEF_OAUTH2_SECRET: <secret>
  • Also add the chef-server host address against the following parameter as follows:
      Note that we are using a named server. But we will be pointing this to our local chef-server IP in the following step.
  • Now create a hosts mapping in /etc/hosts file in your machine as follows so that any request to chef-server goes to the chef server IP:
    • <chef-server IP>
  • Change the port and protocol so that those match with the redirect url set in the chef-server as follows:
    • PORT=4000
    • PROTOCOL=https
  • Now edit the Procfile so that the rails server starts at port 3000 as follows:
    • web: bundle exec rails server --binding localhost -p 3000
  • This is the end of supermarket setup. Now let’s move to nginx configuration.

Nginx Configuration

  • Install Nginx in mac using Homebrew
    • brew install nginx
  • generate ssl ceritificate
    • openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /usr/local/etc/nginx/cert.key -out /usr/local/etc/nginx/cert.crt
  • Go to /usr/local/etc/nginx and update the conf file as follows:
worker_processes  1;
events {
    worker_connections  1024;

http {
    include       mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       4000 ssl;
        server_name  localhost;
        ssl_certificate      cert.crt;
        ssl_certificate_key  cert.key;
        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;
        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

        location / {
            proxy_pass http://localhost:3000/;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header origin 'https://localhost:4000';

  • start Nginx
    • brew services start nginx

-------------------------This is the end of setup. You should be good to go-------------------------
