Ok, this is how create a simple nginx cookbook for Chef

For this example I don’t use chef-server, but i work directly on the machine. In my case the machine is a Vagrant VM based on Ubuntu/xenial64, but i think that you can use a VPS or Cloud service and others Linux OS.

As first thing to do, we must install ChefDK on our machine:

curl https://omnitruck.chef.io/install.sh | sudo bash -s -- -P chefdk -c stable
Enter fullscreen mode Exit fullscreen mode

Then we have to create a folder called cookbooks where we will go to insert our cookbooks:

mkdir cookbooks
Enter fullscreen mode Exit fullscreen mode

inside the cookbooks folder we create our first cookbook named mynginx:

cd cookbooks
Enter fullscreen mode Exit fullscreen mode
chef generate cookbook mynginx
Enter fullscreen mode Exit fullscreen mode

Edit the file default.rb in in mynginx/recipes/default.rb

package 'git'
package 'tree'

package 'nginx' do
  action :install
end


service 'nginx' do
  action [ :enable, :start ]
end


cookbook_file "/var/www/html/index.html" do
  source "index.html"
  mode "0644"
end


template "/etc/nginx/nginx.conf" do   
  source "nginx.conf.erb"
  notifies :reload, "service[nginx]"
end
Enter fullscreen mode Exit fullscreen mode

from inside the mynginx folder I must generate a file index.html:

chef generate file index.html
Enter fullscreen mode Exit fullscreen mode

edit the file index.html in files/default/index.html

<html>
  <head>
    <title>Hello there</title>
  </head>
  <body>
    <h1>This is a test</h1>
    <p>Please work!</p>
  </body>
</html>
Enter fullscreen mode Exit fullscreen mode

create a templates named nginx.conf:

chef generate template nginx.conf
Enter fullscreen mode Exit fullscreen mode

edit the file nginx.conf.erb in templates/nginx.conf.erb and insert your custom configuration of nginx.

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##
    # Gzip Settings
    ##

    gzip on;
    gzip_disable "msie6";

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}


#mail {
#   # See sample authentication script at:
#   # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
# 
#   # auth_http localhost/auth.php;
#   # pop3_capabilities "TOP" "USER";
#   # imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
#   server {
#       listen     localhost:110;
#       protocol   pop3;
#       proxy      on;
#   }
# 
#   server {
#       listen     localhost:143;
#       protocol   imap;
#       proxy      on;
#   }
#}
Enter fullscreen mode Exit fullscreen mode

now you can launch chef-client in local mode for install or update your machine:



sudo chef-client -z --runlist "mynginx"
Enter fullscreen mode Exit fullscreen mode
