Benchmarks getting azure private images
#
# This script has been adapted from a similar script by Dave Gynn (@dgynn):
#
# - https://gist.github.com/dgynn/bd54e970f8942ce2ca532e4adc3fd30a
#
# And the functionality has been heavily modified and made configurable from a
# script by Daniel Berger (@djberg96)
#
# - https://gist.github.com/djberg96/809562e6e7868966a22032935ee6e5e8
#
# With updates to allow different forms of profiling and performance
# improvements around the original script, and for profiling only subsets of
# the data. Also makes use of `VCR` to reduce variations of results between
# runs.
#
# Requires ruby and a semi recent version of bundler (> 1.10)
#
# Git is optional, but the script will have to be updated in the inline gemfile
# to use the non-git version of the `memory_profiler` gem (see comments)
#
#
#
# This can be run against a local version of Azure::Armrest or the latest gem
# release for comparison
#
# Run at least once with --install-gems to ensure all required Gems are installed
#
# ruby ./azure_private_images_benchmark.rb --install-gems
#
# If you wish to change gems (based on options, see below), you must re-run
# with --install-gems
#
#
#
# To run against local code
#
# ruby ./azure_private_images_benchmark.rb --local
#
# To run against latest release
#
# ruby ./azure_private_images_benchmark.rb

### Option Parsing ###
options = { :install_gems => false, :local => false, :sa_samples => 10 }
ARGV.options do |opts|
opts.banner = "Usage: #{File.basename $PROGRAM_NAME} [options]"
opts.on("--install-gems", "Bundle install the gems. Run with this flag once.") do |install|
options[:install_gems] = install
end
opts.on("--local", "Run against local code rather than installed gem") do |local|
options[:local] = local
end
opts.on("--silent-bundler", "Don't display bundler output") do
require "bundler"
options[:ui] = Bundler::UI::Silent.new
end
opts.on("--profile", "Profile a sample of the storage accounts") do
options[:profile] = true
options[:profile_full] = false
end
opts.on("--samples=SAMPLES", "Number of storage account samples to use") do |samples|
options[:sa_samples] = samples.to_i
end
opts.on("--profile-full", "Profile all of the storage accounts (could take time)") do
options[:profile] = false
options[:profile_full] = true
end
# Can't use this with ---profile or --profile_full
# Not currently implemented
opts.on("--mem-over-time", "Capture memory over time (requires fork)") do
options[:mem_over_time] = true
end
opts.on("-h", "--help", "Show this help") { puts opts; exit }
opts.parse!
end
### Dependency Handling ###
bundler_keys = [:ui]
bundler_opts = options.select {|k,v| bundler_keys.include?(k) && v }
gemfile(options[:install_gems], bundler_opts) do
source "https://rubygems.org"
if options[:local]
gem "azure-armrest", :path => "./"
else
gem "azure-armrest"
end
gem "vcr"
gem "webmock"
# gem "memory_profiler"
#
# This version has some unreleased improvements in place that very much
# improve the string analysis of memory_profiler when dealing with
# c-extensions.
gem 'memory_profiler', :github => 'dgynn/memory_profiler', :branch => 'reduced-string-memory'
gem "sys-proctable", :require => false

### Azure::Armrest configuration ###
#
# Put your real credentials in a file in tmp/azure_credentials.cfg with the
# following format (extra spacing optional, but at least 1 is needed):
#
# tenant_id: [TENANT_ID_HERE]
# subscription_id: [SUBSCRIPTION_ID_HERE]
# client_id: [CLIENT_ID_HERE]
# client_key: [CLIENT_KEY_HERE]
#

key, val = line.split(/: +/)
next if key.nil?

end
conf = Azure::Armrest::Configuration.new(az_keys)
### VCR Configuration ###
VCR.configure do |config|
config.cassette_library_dir = Pathname.new(Dir.pwd).join('tmp', 'vcr_cassettes').to_s
config.hook_into :webmock
end
images = nil
### Main Script ###
