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
Then we have to create a folder called cookbooks where we will go to insert our cookbooks:
mkdir cookbooks
inside the cookbooks folder we create our first cookbook named mynginx:
cd cookbookschef generate cookbook mynginx
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
from inside the mynginx folder I must generate a file index.html:
chef generate file index.html
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>
create a templates named nginx.conf:
chef generate template nginx.conf
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;
# }
#}
now you can launch chef-client in local mode for install or update your machine:
sudo chef-client -z --runlist "mynginx"
Good Luck!
