Custom Chef Resource to start newrelic-infra in ubuntu - ruby

Question

Initially I started looking at Configure New Relic Infrastructure using Chef to setup newrelic infra chef cookbook for my project using chef solo, after some research I found that the dependencies in the cookbook is no longer supported.
So I decided to write a custom resource in the recipe so I can utilize chef idempotency.
I have tried the following steps under Install for Ubuntu in my ubuntu box and verified new relic-infra installation:
Now I am trying write a chef resource like this:
Step1: Create a configuration file, and add your license key:
echo "license_key: YOUR_LICENSE_KEY" | sudo tee -a /etc/newrelic-infra.yml
Added this resource block in my recipe for Step1:
file '/etc/newrelic-infra.yml' do
content 'license_key: added_key_here'
mode '0755'
owner 'root'
group 'root'
end
Step2: Enable New Relic's GPG key:
curl https://download.newrelic.com/infrastructure_agent/gpg/newrelic-infra.gpg | sudo apt-key add -
Added this resource block in my recipe for Step2:
apt_repository 'newrelic_key' do
uri 'https://download.newrelic.com/infrastructure_agent/gpg'
trusted true
key 'https://download.newrelic.com/infrastructure_agent/gpg/newrelic-infra.gpg'
end
I verified this step in the local box by listing the keys using this command:
sudo apt-key list
Step3: Create the agent's apt repo using the command for your distribution version:
printf "deb [arch=amd64] https://download.newrelic.com/infrastructure_agent/linux/apt bionic main" | sudo tee -a /etc/apt/sources.list.d/newrelic-infra.list
Added this resource block in my recipe for Step3:
file '/etc/apt/sources.list.d/newrelic-infra.list' do
content 'deb [arch=amd64] https://download.newrelic.com/infrastructure_agent/linux/apt bionic main'
mode '0755'
owner 'root'
group 'root'
end
Step4: Update your apt cache and Run the install script:
sudo apt-get update
sudo apt-get install newrelic-infra -y
Added this resource block in my recipe for Step4:
apt_update
apt_package 'newrelic-infra'
Error:
But the install fails with the following error:

I ran my vagrant file and it works for every step successfully but fails in the final install step... What am I doing wrong? Any troubleshooting tips would be helpful. Thanks!

Answer 1

firstly, you can combine together steps 2 and 3 using apt_repository by utilizing the arch and distribution.
if you read apt_repository documentation, you can see that you can even drop the apt update in step 4
Adding a new repository will update the APT package cache immediately.
secondly, back to your question...
from looking at your logs, specifically
default: execute[apt-get -q update] (/opt/chefdk/embedded/lib/ruby/gems/2.5.0/gems/chef-14.4.56/lib/chef/provider/apt_update.rb line 70) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '100'
it appears that you do not run chef-client on your node, rather you are using chef-dk. make sure that you are running chef-client (or chef infra client nowadays) within the node that you like to converge.
you can run chef-client in higher log level to reveal more about the execution by specifying the log_level
The level of logging to be stored in a log file. Possible levels: auto (default), debug, info, warn, error, or fatal. Default value: warn (when a terminal is available) or info (when a terminal is not available).
i hope it will help you solving your issue

Answer 2

Thanks again #Mr for providing your input. If anyone is wondering about the custom resource for new relic infra, here you go:
file '/etc/newrelic-infra.yml' do
content 'license_key: added my license key here'
mode '0755'
owner 'root'
group 'root'
end
apt_repository 'newrelic-infra' do
uri 'https://download.newrelic.com/infrastructure_agent/linux/apt'
trusted true
arch 'amd64'
components ['main']
distribution 'bionic'
key 'https://download.newrelic.com/infrastructure_agent/gpg/newrelic-infra.gpg'
end
