I wrote an automized puppet file for the installation with Vagrant.
It's just for a fast installation for a apache web server (with PHP5, MySQL)
and atm it is as simple as possible for the beginning.
Every time I start up my Vagrant I get these messages and couldn't interpret
by myself:
←[0;36mnotice: /Stage[main]/Lamp/Package[php5]/ensure: ensure changed 'purged' t
o 'present'←[0m
←[0;36mnotice: /Stage[main]/Lamp/Package[mysql-client]/ensure: ensure changed 'p
urged' to 'present'←[0m
←[0;36mnotice: /Stage[main]/Lamp/Package[mysql-server]/ensure: ensure changed 'p
urged' to 'present'←[0m
←[0;36mnotice: /Stage[main]/Lamp/Package[apache2]/ensure: ensure changed 'purged
' to 'present'←[0m
This is not an error at all.
It just says, that the state of those packages has changed from purged to present.
purged = not installed
present = installed
It just means, the package was installed successfully.

I am getting my toes wet with chef at my job and have been tasked with installing making a recipe to install telegraf on our machines with custom configs. Let me also preface this with I have no ruby experience.
Before downloading or installing telegraf I want to verify that the if telegraf exists to only do all the following work if the versions miss match.
So I have attempted to set an attribute during the recipe runtime that other resources will check against.
ruby_block 'get telegraf version' do
block do
#tricky way to load this Chef::Mixin::ShellOut utilities
Chef::Resource::RubyBlock.send(:include, Chef::Mixin::ShellOut)
command = 'C:\\Program Files\\telegraf\\telegraf.exe --version'
command_out = shell_out(command)
node.default['windows']['telegraf']['installed_version'] = 'good'
end
notifies :write, 'log[log_version]', :delayed
action :run
only_if { ::File.exists?('C:\\Program Files\\telegraf\\telegraf.exe')}
end
log 'log_version' do
message node['windows']['telegraf']['installed_version']
level :error
end
When I look at the output though I see
* ruby_block[get telegraf version] action run[2018-07-23T14:48:11-07:00] INFO: Processing ruby_block[get telegraf version] action run (win-telegraf::telegraf line 26)
[2018-07-23T14:48:11-07:00] INFO: ruby_block[get telegraf version] called
- execute the ruby block get telegraf version
* log[log_version] action write[2018-07-23T14:48:11-07:00] INFO: Processing log[log_version] action write (win-telegraf::telegraf line 39)
[2018-07-23T14:48:11-07:00] ERROR:
So why is it when I read node['windows']['telegraf']['installed_version'] that the log prints nothing instead of 'good'?
Chef uses a two-pass loading system, check out https://coderanger.net/two-pass/ for more details. But the tl;dr for this case is that the stuff inside block do ... end runs in the second phase, while the Ruby code for the log resource is evaluated in the first phase. In general you can fix this using the lazy{} helper, but in this case what you probably want is either a custom resource or an Ohai plugin. For "normal" Windows applications, this is all handled by the MSI subsystem and the windows_package resource, but as Telegraf doesn't offer MSI packages you are a bit out of luck. That said, there are packages available for Chocolatey (a Windows packaging system like Mac's Homebrew) so you might want to look into using that instead of writing this yourself.
I have a Go program that uses aws-sdk-go to talk to dynamodb. Dependencies are vendored. Go version 1.7.1. aws-sdk-go version 1.6.24. The program works as expected in all the following environments:
dev box from shell (Arch Linux)
docker container running on my dev box (Docker 1.13.1)
Ec2 instance from shell (Ubuntu 16.04)
When I run the docker container on kubernetes (same one I tested on my dev box), I get the following error:
2017/03/02 22:30:13 DEBUG ERROR: Request dynamodb/GetItem:

Based on:
https://golang.org/src/net/http/transport.go
https://godoc.org/golang.org/x/net/lex/httplex#ValidHeaderFieldValue
It looks like the problem is with the header value validation, yet I am at a loss to understand why it works everywhere except on my k8s cluster. The cluster is composed of Ec2 instances running the latest CoreOS stable ami (CoreOS stable 1235.8.0)
The docker image that works on my dev machine is scratch based. To troubleshoot I created an image based on Ubuntu latest with a separate go program that just does a simple get item from dynamodb. When this image is run on my k8s cluster and the program run from an interactive shell, I get the same errors. I have confirmed I can ping the dynamodb endpoints from this env.
I am having a hard time troubleshooting this issue: am I missing something stupid here? Can someone point me in the right direction or have an idea of what is going on?
remember the "-n" when you do this:
echo -n key | base64
The \n after hidden is certainly invalid. Not sure if it is actually there or somehow got inserted when you were cleansing for posting.
Consider:
package main
import (
"fmt"
"golang.org/x/net/lex/httplex"
)
func main() {
fmt.Println("Is valid (without new line)", httplex.ValidHeaderFieldValue("AWS4-HMAC-SHA256 Credential=hidden/20170302/us-east-1/dynamodb/aws4_request, SignedHeaders=accept-encoding;content-length;content-type;host;x-amz-date;x-amz-target, Signature=483f56dd0b17d8945d3c2f2044b7f97e531190602f132a4d5f828264b3a2cff2"))
fmt.Println("Is valid (with new line)", httplex.ValidHeaderFieldValue("AWS4-HMAC-SHA256 Credential=hidden\n/20170302/us-east-1/dynamodb/aws4_request, SignedHeaders=accept-encoding;content-length;content-type;host;x-amz-date;x-amz-target, Signature=483f56dd0b17d8945d3c2f2044b7f97e531190602f132a4d5f828264b3a2cff2"))
}
One guess would be wherever the real hidden value is getting pulled from (config file etc) mistakenly has the \n in there and it's happily getting pulled into your header, but only in this case.
I am having some problems trying to bootstrap a windows node for Chef. This node was initially able to be partially bootstrapped, it was getting through most of the process but however, failing near the end - on the windows client itself I can see a number of expected files under C:\Chef
However since upgrading my Ruby and Knife-Windows to remedy the original issue - I am now not able to bootstrap at all, I get the error below:
chefadmin#AUK-CHEFMGT1:~$ knife bootstrap windows winrm 10.28.154.61 -x chefadmin -P xxxxxx
/opt/chefdk/embedded/lib/ruby/gems/2.1.0/gems/chef-12.5.1/lib/chef/mixin/path_sanity.rb:25:

Remote node responded after 0.01 minutes.
Bootstrapping Chef on 10.28.154.61
ERROR: RuntimeError: Knife-Windows < 1.0 does not support validatorless bootstraps
I've tried a few different versions of knife-windows, initially 1.1.1, and most recently the pre-release version of 1.0.0 rc1, however, they are all giving me this error.
I am not sure why this is a problem, as the validation.pem does exist on the windows client in C:\Chef\
In case it matters, here is my knife.rb config file:
chefadmin#AUK-CHEFMGT1:~$
GNU nano 2.2.6 File: /home/chefadmin/chef-repo/.chef/knife.rb
current_dir = File.dirname(__FILE__)
log_level :info
log_location STDOUT
node_name "chefadmin"
client_key "#{current_dir}/ChefRSA.pem"
validation_client_name "company"
validation_key "#{current_dir}/companyvalidator"
chef_server_url "https://10.28.253.101/organizations/company"
syntax_check_cache_path "#{ENV['HOME']}/.chef/syntaxcache"
cookbook_path ["#{current_dir}/../cookbooks"]
"#{current_dir}/companyvalidator" Does that file exist? Usually that would be something ending in .pem. If that path isn't a thing, it would fall back to new-style bootstrapping which I don't think works on Windows yet.
I'm trying to use chef to check out a git repo to a windows client node.
This seems simple enough and I've got the following resource definition:
git "C:\\pathtocheckout" do
repo "https://gitserver/repo.git"
action [ :checkout, :sync]
end
But when this is reached by chef-client I get:
Errno::EIO: git[C:\pathtocheckout] (cookbook_name::test line 21) had an error: Errno::EIO: Input/output error - CreateProcessW
I've had a look at the stacktrace produced and it appears to be something to do with creating a process to run the git command - but this is the limit of my knowledge.
I've made sure git is installed on on Path, removed all other recipes from the run list, running as a different admin user and I've tried different repositories but all with the same error.
So I'm pretty stumped - anyone got a way I can dig into this error and see what is going on?
I have a Ruby script (non-Rails) that connects to a SQL Server database. When run from the command line, it runs fine. When executed via an http request, it generates an error, specifically when opening the DB connection. Something about the combination of the http/SQL methods is failing.
I'm running the script on a machine with: Windows 7 Ultimate (64-bit), Ruby 1.9.3p125, Apache 2.2.11. The database is SQL Server 10.0.4000, hosted on a separate (corporate, internal) server.
The script looks something like this:
#!/Ruby193/bin/ruby
require 'win32ole'
...
$qadb = nil
begin
$qadb = SqlServer.new('192.168.100.249', 'qauser', 'password')
$qadb.open('qadb')
rescue
logRegression("Rescued: Unable to access QADB: #{$!}")
end
The SqlServer class is based on David Mullet's code, found at http://rubyonwindows.blogspot.com/2007/03/ruby-ado-and-sqlserver.html (not copied here for brevity).
From the command line, the DB opens fine and I get an expected result from the script. When I call the script via my internal server (http://qatools/getTask.rb) I get the following error in my log file:
Rescued: Unable to access QADB: failed to create WIN32OLE object from `ADODB.Connection'
HRESULT error code:0x8007007e
The specified module could not be found.
I've considered that I might be missing a DLL. Other research led me to ntwdblib.dll -- I tried downloading a copy and placing it in various folders. I've also considered that I might be facing an Apache configuration issue and/or a security/permissions issue but I haven't found any solutions for those that seem to fit my specific problem.
Any ideas?
