Chef SRE DigitalOcean

I use this repo for a challenge, it's a cookbook to deploy a node.js app.

Requirements

• Chef-server;
• knife;
• CentOS 7.6

How-to

This directory contains the chef-repo where cookbooks are stored and a simple script to register the node on chef-server.

• Copy the first_boot_chef.sh to the server;

./first_boot_chef.sh

After the execution it's finished the server it's registered on Chef-server with nodejs installed.

Knife

We must copy the user and the validation key from the Chef-server to our workstation.

mkdir -p /Users/tadeu/.chef 
touch knife.rb

Your's knife.rb file must look like this:

node_name 'tadeu'
client_key '/Users/tadeu/.chef/tadeu.pem'
chef_server_url 'https://centos-s-2vcpu-4gb-nyc1-01/organizations/lnx_teste'
validation_key '/Users/tadeu/.chef/lnx_teste.pem'
cookbook_path '/Users/tadeu/lnx_sre/chef-repo/cookbooks/'
validation_client_name 'lnx_teste'
log_level :info
log_location STDOUT
node_name 'tadeu'
syntax_check_cache_path '/root/.chef/syntax_check_cache'
knife[:editor]="vim"

knife ssl fetch
knife ssl check

• To check:

knife client list 

• Upload cookbooks:

knife cookbook upload nodejs --force
knife cookbook upload bootstrap_lnx

• Add the bootstrap_lnx recipe:

knife node run_list add <node> "recipe[bootstrap_lnx]"

• Chef-client on node

chef-client
