Building a Multi-node Vagrant Splunk Environment, Part 2

Multi-node Vagrant Splunk Environment

By Michael O’Leary, Senior Consultant

As a Senior Consultant at Avocado, I recommend creating several environments prior to production for clients in the early stages of the DevOps journey. In my previous blog post, I focused on creating a multi-node development environment. This was to assist DevOps/ Splunk engineers developing on their local workstation or laptop. I went through the process of creating a basic lab with four tiers for a Splunk architecture (including management, searching, indexing and forwarding tier). In this part, I will explore the integration of the Ansible playbooks. This will assist you with on the fly provisioning of the virtual machine, creating a provisioning server with Ansible installed. This will produce roles in which to provision the servers.

Update the guests.yml file

Firstly let’s update the guests.yml file which should include our provisioning server. This server is called “mgmt”. Remember this is not a Splunk server. It is a provisioning server to be used if you don’t want to install Ansible on your host machine or if your host runs on Windows. I’ve added a shell script to install Ansible on CentOS 7 and another script to set the bash_profile prompt, however mileage may vary using other vagrant boxes.  The following shell script is to be executed in the guests.yml file.

In addition, I have included a code block to process the scripts located in the options of guests.yml. under the guest provisioning block.

The ansible_install.sh file looks like the following, it’s a quick and dirty shell installer for Ansible.

ansible_install

So let’s bring up our mgmt box. As in the previous article “vagrant up mgmt” will execute this. Ensure the shell provisioner is running the Ansible install process.

From your host machine, login into the ‘mgmt’ node using “vagrant ssh mgmt”.  Confirm that ansible is installed by running the “ansible –version” command.

To source the environment variables we want to configure – there is a script under the root directory called conf_ansible_env.sh.  This is used to set the ANSIBLE_ENV and ANSIBLE_CONFIG variables. To see a list of parameters that can be specified, run the script with no parameters identified. 

10:17 $ ./conf_ansible_env.sh
Set variables with the following flags
  -e {{ ENVIRONMENT }}
  -p {{ VAGRANT_PROVIDER }}
Example Usage: source conf_ansible_env.sh -e dev -p parallels 



Current settings are:
ANSIBLE_ENV: cluster
ANSIBLE_CONFIG: /Users/moleary/Workspace/multinode-lab/ansible/vars/cluster/ansible.cfg
VAGRANT_DEFAULT_PROVIDER:

In addition, to get a list of valid parameters, use the ‘list’ command when specifying the environment or provider (see below for an example).  The default environment and provider is ‘cluster’ and ‘vagrant’ respectively.

✔ ~/Workspace/multinode-lab [master|✚ 2]
11:06 $ ./conf_ansible_env.sh -e list
Ansible Environment is current set to: cluster
Selectable vagrant environments are
 - cluster
 - single
✔ ~/Workspace/multinode-lab [master|✚ 2]
11:06 $ ./conf_ansible_env.sh -p list
Current Default Vagrant provider is not set
Selectable vagrant providers are
 - virtualbox
 - parallels

Currently, two environments have been displayed in the output above. In a later blog I will expand these.

Ansible folder

Next we will add an Ansible folder. This folder will contain all the automation for our servers including roles, variables and playbooks. Ansible is described as self-documenting. The tasks in the roles and playbooks should tell you what the automation code is doing. Under the Ansible folder, I’ve created two subdirectories, “vars” and “roles”.

The “vars” folder contains all variables for the specific environment. In this case our environment is the “cluster” folder. I have also created an environment called “single” for the Splunk environment which has one combined search head / indexer (a common architecture for the sub 100 GB/day).

The “roles” contains the following for the configuration of our Splunk cluster:

  • Base – The base role for common configurations across the infrastructure, for example setting up a Splunk repository
  • Certificates – The certificate role is used to generate SSL certificates and configuration required to enable secure forwarding with SSL compress
  • Splunk – A common Splunk role for installing a Splunk base
  • Cluster Master – The Splunk role to create the cluster master
  • Indexer – The Splunk role to create the indexers
  • Search Head – The Splunk role to create the search heads
  • Universal_Forwarder – The Splunk roles to install the universal forwarder agent and configure deployment server
  • Local – A local host role that will download the Splunk binaries from their website

In addition to the roles above, I have created a repo directory which will be “rsynced” or shared (via virtualbox guest additions) to each individual server. This will be used to serve the binaries for splunk and the splunk universal forwarder as a custom yum repository. I have also added the splunk_repo.yml under the base role to create the necessary files for the repository to work. This will allow the standard “yum install splunk –y” to work as well. 

We need to ensure that we have connectivity with the other nodes using the “ansible -m ping all” command. This command should be run from the root of the project folder (which is /vagrant when using the mgmt box). If everything is green then we have connectivity via Ansible (see the screenshot below for reference).

Running the “run_main_play.sh” from the root of the project folder will configure the available nodes and output the urls for the web interfaces. I have included a standard playbook run below for reference.

If you would like to take a look at a copy of the lab, please check out the master branch that I have publicised.

I hope these posts have assisted you in the basic architecture. As part of Avocado’s daily consulting practice, Avocado engineers have an in depth experience of working with clients to build multiple environments. If you would like to discuss this further please get in touch through hello@avocado.com.au
