Ruby in Docker Oddity
## Summary
I have a set of rspec tests that run for a repo. My runner is using the config below:
```
concurrent = 1
check_interval = 0
[[runners]]
name = "centos-7-docker"
url = "https://code.example.com/"
token = "my token here"
executor = "docker"
[runners.docker]
tls_verify = false
image = "genebean/cent7runner:latest"
privileged = false
disable_cache = false
volumes = ["/cache"]
[runners.cache]
```
If I run the same code with the same test and the same Docker image on my local machine everthing works but when run in GitLab CI I get this error:
```

## Steps to reproduce
Run this Rakefile and Gemfile via GitLab CI:
```ruby
# Rakefile
require 'rubygems'
require 'puppet_blacksmith/rake_tasks'
require 'puppetlabs_spec_helper/rake_tasks'
require 'puppet-lint/tasks/puppet-lint'
require 'yamllint/rake_task'
exclude_paths = [
"pkg/**/*",
"vendor/**/*",
"spec/**/*",
]
PuppetLint.configuration.fail_on_warnings = true
PuppetLint.configuration.ignore_paths = exclude_paths
PuppetLint.configuration.log_format = "%{path}:%{linenumber}:%{check}:%{KIND}:%{message}"
PuppetSyntax.exclude_paths = exclude_paths
desc "Validate manifests, templates, and ruby files"
task :validate do
Dir['manifests/**/*.pp'].each do |manifest|
sh "puppet parser validate --noop #{manifest}"
end
Dir['spec/**/*.rb','lib/**/*.rb'].each do |ruby_file|
sh "ruby -c #{ruby_file}" unless ruby_file =~ /spec\/fixtures/
end
Dir['templates/**/*.erb'].each do |template|
sh "erb -P -x -T '-' #{template} | ruby -c"
end
end
YamlLint::RakeTask.new do |yamllint|
yamllint.paths = %w(
**/*.yml
**/*.yaml
)
end
task :tests do
Rake::Task[:lint].invoke
Rake::Task[:validate].invoke
Rake::Task[:yamllint].invoke
Rake::Task[:spec].invoke
end
```
```ruby
# Gemfile
# vim:ft=ruby
source 'https://rubygems.org'
if ENV.key?('PUPPET_VERSION')
puppetversion = "#{ENV['PUPPET_VERSION']}"
else
puppetversion = ['~> 4.0']
end
group :development, :unit_tests do
if RUBY_VERSION < '2.0'
gem 'json', '1.8.3'
gem 'json_pure', '1.8.3'
else
gem 'json', '>= 2.0.2'
gem 'json_pure', '>= 2.0.2'
end
gem 'metadata-json-lint', '~> 0.0.6'
gem 'puppet', puppetversion
gem 'puppet-lint', ['>= 1.0.0', '< 1.1.0']
gem 'puppetlabs_spec_helper', '~> 0.10'
gem 'rspec-puppet', '~> 2.0'
gem 'yamllint', '~> 0.0.9'
# puppet-lint plugins
gem 'puppet-lint-absolute_classname-check', '~> 0.1'
gem 'puppet-lint-empty_string-check', '~> 0.2'
gem 'puppet-lint-leading_zero-check', '~> 0.1'

gem 'puppet-lint-undef_in_function-check', '~> 0.1'
gem 'puppet-lint-unquoted_string-check', '~> 0.2'
gem 'puppet-lint-variable_contains_upcase', '~> 1.0'
end
group :packaging do
gem 'puppet-blacksmith', '>= 3.3.0'
end
```
## Actual behavior
The error shown at the top is thrown
## Expected behavior
The test to run without issue as it does when running it in the Docker container locally.
