Consul must first be installed on your machine. Consul is distributed as a  binary package  for all supported platforms and architectures. This page will not cover how to compile Consul from source, but compiling from source is covered in the  documentation  for those who want to be sure they're compiling source they trust into the final binary. Installing Consul To install Consul, find the  appropriate package  for your system and download it. Consul is packaged as a zip archive. After downloading Consul, unzip the package. Consul runs as a single binary named  consul . Any other files in the package can be safely removed and Consul will still function. The final step is to make sure that the  consul  binary is available on the  PATH . See  this page  for instructions on setting the PATH on Linux and Mac.  This page  contains instructions for setting the PATH on Windows. Verifying the Installation After installing Consul, verify the installation worked by opening a new terminal se...

Chef is a powerful automation platform that transforms infrastructure into code. Whether you’re operating in the cloud, on-premises, or in a hybrid environment, Chef automates how infrastructure is configured, deployed, and managed across your network, no matter its size. This diagram shows how you develop, test, and deploy your Chef code. The workstation is the location from which users interact with Chef. On the workstation users author and test  cookbooks  using tools such as  Test Kitchen  and interact with the Chef server using the  knife  and  chef command line tools. Nodes are the machines—physical, virtual, cloud, and so on—that are under management by Chef. The chef-client is installed on each node and is what  performs the automation on that machine . Use the Chef server as your foundation to create and manage flexible, dynamic infrastructure whether you manage 50 or 500,000 nodes, across multiple datacenters, public and private clouds, and in heterogeneous environments...

The  service-list  subcommand is used to display a list of all available services. A service that is enabled is labeled with an asterisk (*). This subcommand has the following syntax: $ chef-server-ctl service-list The output will be as follows: bookshelf* nginx* oc_bifrost* oc_id* opscode-chef-mover* opscode-erchef* opscode-expander* opscode-pushy-server* opscode-reporting* opscode-solr4* postgresql* rabbitmq* redis_lb* bifrost ¶ The  oc_bifrost  service ensures that every request to view or manage objects stored on the Chef server is authorized. status ¶ To view the status for the service: $ chef-server-ctl status bifrost to return something like: $ run: bifrost: ( pid 1234 ) 123456s ; run: log: ( pid 5678 ) 789012s start ¶ To start the service: $ chef-server-ctl start bifrost stop ¶ To stop the service: $ chef-server-ctl stop bifrost restart ¶ To restart the service: $ chef-server-ctl restart bifrost to return something like: $ ok: run: bifrost: ( pid 1234 ) 1234s kill ¶ To kill...

Create a linux machine, login into it and execute the following command: curl -s https://omnitruck.chef.io/install.sh | sudo bash -s -- -P chefdk Now we need to change the default ruby to point it to the chef ruby and not the system ruby. Execute the following command for it. echo 'eval "$(chef shell-init bash)"' >> ~/.bash_profile Note: eval  is part of POSIX. Its an interface which can be a shell built-in.Its described in the "POSIX Programmer's Manual":  http://www.unix.com/man-page/posix/1posix/eval/ eval - construct command by concatenating arguments It will take an argument and construct a command of it, which will be executed by the shell. This is the example of the manpage: 1 ) foo = 10 x = foo 2 ) y = '$' $x 3 ) echo $y 4 ) $foo 5 ) eval y = '$' $x 6 ) echo $y 7 ) 10 In the first line you define  $foo  with the value  '10'  and  $x  with the value  'foo' . Now define  $y , which consists ...

Install docker with the following command: yum install docker systemctl start docker Then we need to install the kitchen-docker ruby gem. chef gem install kitchen-docker Create a cookbook: chef generate cookbook my_cookbook Edit the .kitchen.yml file in the generated cookbook.
