a basic NGINX cookbook chef

#nginx #devops #server #linux

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
