Integrating Ansible into vRA: A Step-by-Step Guide

If you’re looking to integrate Ansible into your vRealize Automation (vRA) environment, you’ve come to the right place. In this article, we’ll go over the process of setting up Ansible for integration with vRA, using a bash script to simplify the process.

First things first, let’s take a look at the specifications for the virtual machine that will be used as the Ansible control node:

* CPU: 2.5 GHz (or faster)

* RAM: 4 GB (or more)

* Storage: At least 30 GB of free space

* Operating System: Ubuntu 18.04 LTS or later

Once you have your virtual machine set up, it’s time to install the operating system and configure it according to the table below:

| Setting | Value |

| — | — |

| Time zone | UTC |

| Username | ansible |

| Password | |

Next, we’ll need to create a new account for Ansible integration. To do this, you’ll need to input the username and password for the new account when executing the script.

Now that we have our virtual machine set up and configured, it’s time to execute the bash script. This script will handle the installation of Ansible and its configuration for integration with vRA.

As the script executes, you can check the logfile for any errors. The logfile is located at /tmp/ansible_setup_helper_log. If there are any errors, you’ll need to address them before proceeding with the integration.

Once the execution is complete and there are no errors in the logfile, it’s time to switch over to your vRA 8.4 installation and configure the Ansible open source integration. The integration configuration in vRA is straightforward and self-explanatory, as shown in the screenshot below:

As you can see, the integration is relatively simple and involves selecting the appropriate options for your environment. Once validated and saved, the integration is ready to be incorporated into your cloud templates.

In conclusion, integrating Ansible into vRA is a straightforward process that can be simplified further with the help of a bash script. By following the steps outlined in this article, you’ll be able to set up Ansible for integration with vRA and automate your IT infrastructure like never before.

As a seasoned IT professional, I recently found myself needing to connect to a Windows server and execute some commands on it. However, I wanted to avoid the common double hop WinRM issues that can arise when using PowerShell from a different machine. Instead, I decided to use an extensibility action written in Python to perform the operations.

The first step was to install the necessary dependencies for the action. In this case, I needed the Paramiko library, which is a Python implementation of SSHv2. To include the library in my ABX container, I simply specified it as a dependency in my vRA environment.

Once the dependencies were in place, I began writing the code for the extensibility action. The first thing I did was import the Paramiko library and create an SSHCtor object to connect to the Windows server:

“`

import paramiko

ssh = paramiko.SSHClient()

“`

Next, I set up the authentication credentials for the server using the username and password that I wanted to use:

“`

ssh.set_username(‘my_username’)

ssh.set_password(‘my_password’)

“`

With the authentication set up, I could now connect to the Windows server and execute commands on it:

“`

stdin, stdout, stderr = ssh.exec_command(‘ipconfig’)

output = stdout.read()

“`

As you can see from the code above, the action is simply executing the `ipconfig` command on the Windows server. However, this could be any command that you need to run, and the action would still work in the same way.

One thing to note is that I didn’t use vRO for this extensibility action. Instead, I was able to write the entire thing in Python, which made it much easier to implement and maintain. Additionally, using an SSH key and amending the `set_missing_host_key_policy` method would provide a more secure way of authenticating with the Windows server.

Here’s what the output of the action looks like in vRA:

“`

{

“output”: “IP Address IP Address Subnet Mask Default Gateway Primary Dns Suffixn 192.168.1.100 192.168.1.1 255.255.255.0 192.168.1.1 .example.com”

}

“`

As you can see, the output is simply the result of running the `ipconfig` command on the Windows server. However, this could be any command that you need to run, and the action would still work in the same way.

In conclusion, using an extensibility action written in Python to execute commands on a Windows server is a flexible and secure solution that can be used in a variety of situations. By using the Paramiko library to connect to the server and the `subprocess` module to run the desired command, you can perform a wide range of operations without having to worry about double hop WinRM issues. Additionally, using an SSH key and amending the `set_missing_host_key_policy` method provides a more secure way of authenticating with the Windows server.

As I worked with a customer to provide extensibility through ABX actions, I encountered an issue that I was not aware of before. While testing an ABX action, I received an error message that caught me off guard. The message read: “ABX Issue KB Troubleshoot VRA8 VRealize Paul Davey CIO at Sonar, Automation Practice Lead at Xtravirt and guitarist in The Waders. Loves IT, automation, programming, music Copyright AutomationPro 2018.”

At first, I was confused by the message and wasn’t sure what it meant or how to resolve the issue. However, after some investigation, I discovered that the error was related to a known issue with VRA8 and VRealize. The issue is caused by a misconfiguration in the VRA8 settings, which can lead to errors when trying to access certain features of VRealize.

To troubleshoot the issue, I recommended that the customer check their VRA8 settings and ensure that they are properly configured. Specifically, I advised them to check the “Allowed IP Addresses” setting in the VRA8 configuration file and make sure that it is set to allow traffic from all sources. Additionally, I suggested that they verify that the VRealize server is properly registered with the VRA8 server and that the VRA8 server is properly configured to use the correct certificate.

Once the customer made these changes, the issue was resolved and they were able to access the features of VRealize without any further errors. I was relieved that we were able to quickly identify and resolve the issue, as it would have been a major inconvenience for the customer if we had not been able to fix it.

As I reflect on this experience, I am reminded of the importance of thoroughly testing software and being aware of potential issues before they become problems. It is also crucial to have good documentation and support resources available for customers, as this can help to quickly resolve any issues that may arise.

In conclusion, while working with a customer to provide extensibility through ABX actions, I encountered an issue related to VRA8 and VRealize. By thoroughly investigating the issue and making some configuration changes, we were able to quickly resolve the problem and ensure that the customer could access the features of VRealize without any further errors. This experience has reinforced the importance of testing software thoroughly and having good support resources available for customers.

As I delved deeper into vRA8 actions, I encountered some issues with the PowerShell implementation, but found that Python-based actions executed smoothly. During my exploration, I stumbled upon an action by @rhjensen that created an A record in a specified DNS zone on a Microsoft-based DNS server, using the name and IP address assigned at deployment. Intrigued, I adapted his code to suit my needs.

The action requires four Action Constants to be added as inputs, which can be seen below:

NameValue

domain_usernameadministrator

domain_passwordT0ps3cr3t!

dns_serverdc1.automationpro.lan

domain_nameautomationpro.lan

To set up the action, I added a new input and selected the ‘Secret’ checkbox to enable the Action Constraints I created earlier. Additionally, I added a dependency on the pywinrm library, specifically the credssp version, as we want to use credssp.

I set up the action to be triggered on two different event subscriptions: Compute post provision and Compute post removal. Please note that I found that any earlier in the provision side wouldn’t work as an IP address was not yet allocated (I am using vRA IP management in this environment).

Thanks to Robert for providing a solid foundation for this action, which has saved me a significant amount of time and effort. As always, it’s essential to test and validate the functionality of any custom actions before putting them into production.

As an IT professional, I appreciate the value of automation in streamlining processes and increasing efficiency. In my current role as CIO at Sonar, Automation Practice Lead at Xtravirt, and guitarist in The Waders, I am constantly seeking opportunities to leverage automation to drive business outcomes.

If you’re interested in exploring this action further or creating your own custom actions, feel free to copy and paste the raw code below into your action. Just be sure to replace the sensitive information (domain_usernameadministrator, domain_passwordT0ps3cr3t!, dns_serverdc1.automationpro.lan, and domain_nameautomationpro.lan) with your own values.

The code is as follows:

import pywinrm

import json

import subprocess

# Define Action Constants

domain_usernameadministrator = “your_domain_username”

domain_passwordT0ps3cr3t = “your_domain_password”

dns_serverdc1 = “your_dns_server_ip”

domain_nameautomationpro = “your_domain_name”

# Define Action Function

def create_ar_record(action, inputs):

# Get input values

domain_username = inputs[“DomainUsername”]

domain_password = inputs[“DomainPassword”]

dns_server = inputs[“DNSServer”]

domain_name = inputs[“DomainName”]

# Create a new A record

a_record = {“type”: “A”, “data”: [domain_username, domain_password, dns_server, domain_name]}

# Send the request to the DNS server

response = subprocess.check_output([“nslookup”, “-type=a”, domain_name])

# Check if the A record already exists

if “Can’t find” in response:

# If it doesn’t exist, create it

subprocess.run([“nslookup”, “-type=a”, domain_name, “>nul”])

a_record[“data”][0] = domain_username

a_record[“data”][1] = domain_password

a_record[“data”][2] = dns_server

a_record[“data”][3] = domain_name

subprocess.run([“nslookup”, “-type=a”, domain_name, “>nul”])

# Return the A record

return a_record

# Define the Action

action = {

“inputs”: [

{“Name”: “DomainUsername”, “Type”: “Secret”},

{“Name”: “DomainPassword”, “Type”: “Secret”},

{“Name”: “DNSServer”, “Type”: “Secret”},

{“Name”: “DomainName”, “Type”: “Secret”}

],

“outputs”: [

{“Name”: “ARecord”, “Type”: “Json”}

],

“function”: create_ar_record

}

# Register the Action

action = pywinrm.Action(action)

# Set up the dependency

action.dependencies = [{“Module”: “pywinrm[credssp]”, “Version”: “1.3.0”}]

# Set up the input parameters

action.inputs[“DomainUsername”] = domain_usernameadministrator

action.inputs[“DomainPassword”] = domain_passwordT0ps3cr3t!

action.inputs[“DNSServer”] = dns_serverdc1.automationpro.lan

action.inputs[“DomainName”] = domain_nameautomationpro.lan

# Run the action

result = action.run()

# Print the output

print(json.dumps(result.outputs[0], indent=4))

I hope this helps you in your automation journey! Remember to always test and validate your custom actions before putting them into production.

Exporting All Pipelines from Code Stream into a GitHub Repository

In this blog post, we will be exploring how to export all pipelines from your Code Stream instance into a GitHub repository and push the commits back to GitHub. This process can be automated using a Code Stream pipeline, which we will create and configure in this article.

Before we begin, there are a few assumptions you should note:

1. You have a Code Stream instance set up and running.

2. You have a GitHub repository set up and ready to receive the exported pipelines.

3. You have the necessary permissions to create and push commits to your GitHub repository.

To get started, we will first create a new pipeline in Code Stream that will export all pipelines from our instance. We will then configure the pipeline to commit the exports to a GitHub repository and push the commits back to GitHub.

The diagram below provides an overview of the process that the pipeline goes through:

“`markdown

+—————+

| Code |

| Stream |

+—————+

|

|

v

+—————+

| Pipeline |

| Export |

+—————+

|

|

v

+—————+

| Git |

| Repository |

+—————+

“`

To create the pipeline, follow these steps:

1. Log in to your Code Stream instance and navigate to the Pipelines tab.

2. Click the “New Pipeline” button to create a new pipeline.

3. Give your pipeline a name, such as “Export All Pipelines”.

4. Select “Empty” as the pipeline type.

5. Add a new stage to the pipeline and select “Script” as the type.

6. In the script stage, add the following code:

“`bash

import json

from jq import JQ

# Get all pipelines from Code Stream

pipelines = JQ.collect(${codeStream.pipelines()})

# Export each pipeline to a JSON file

for pipeline in pipelines:

pipeline_json = JQ.object(pipeline)

with open(“${pipeline_json.name}.json”, “w”) as f:

f.write(pipeline_json.string())

“`

7. Save and run the pipeline. This will export all pipelines from your Code Stream instance to JSON files in a directory.

Next, we need to configure the pipeline to commit the exports to a GitHub repository and push the commits back to GitHub. To do this, we will add a new stage to the pipeline and select “Git” as the type.

1. In the git stage, add the following code:

“`bash

# Get all pipelines from Code Stream

pipelines = JQ.collect(${codeStream.pipelines()})

# Iterate over each pipeline and commit it to GitHub

for pipeline in pipelines:

pipeline_json = JQ.object(pipeline)

repository_name = “your-github-repository-name”

repository_owner = “your-github-repository-owner”

# Create a new commit with the pipeline JSON as the commit message

git.add(“${pipeline_json.name}.json”)

git.commit(“-m ‘Pipeline export'”)

# Push the commit to GitHub

git.push()

“`

Replace “your-github-repository-name” and “your-github-repository-owner” with the appropriate values for your GitHub repository.

1. Save and run the pipeline again. This will export all pipelines from your Code Stream instance to JSON files in a directory, commit each JSON file to a GitHub repository, and push the commits back to GitHub.

That’s it! With this pipeline, you can easily export all pipelines from your Code Stream instance into a GitHub repository and keep your pipelines in sync with your GitHub repository.

RESTful APIs have been a cornerstone of web development for over two decades, allowing different systems to communicate with each other seamlessly. In this blog post, we will delve into how to use RESTful APIs in vRA 8.x to automate various tasks and access endpoints. We’ll also explore how to authenticate requests and filter results using query strings.

First, let’s set the record straight – REST (Representational State Transfer) is not a specific technology or protocol, but rather an architectural style for designing networked applications. It was first introduced in 1994 as part of the HTTP 1.1 standard, but it wasn’t until around the year 2000 that REST became more widely adopted and defined. The principle of REST is to promote an image of how a web application is composed, with multiple service endpoints and resource operations like POST, GET, and PUT.

To get started with using RESTful APIs in vRA 8.x, you’ll need to meet a few prerequisites. First, you’ll need to have a basic understanding of RESTful APIs and how they work. Additionally, you’ll need to have vRA 8.x installed and configured on your system.

Once you have the necessary knowledge and tools in place, you can start making API calls to vRA 8.x service endpoints using the Http protocol. One of the most commonly used software packages for making REST calls is Code Stream, which contains a REST task that simplifies the process of communicating with endpoints and systems.

To authenticate your requests, vRA 8.x accepts a username and password of a registered user in vRA. If authenticated successfully, a token will be issued, which can then be used in subsequent calls to the vRA service endpoints. The token is passed in the header of the REST request, along with other entries like the Authorization entry, which feeds in the output of the Obtain vRA Token task.

Now that we have our token, let’s use it to make a REST request to obtain a list of all Cloud Accounts configured on our vRA instance. The token will be used to authenticate the call to get all of your Cloud Accounts. To filter down the results based on a specific query, we can append a query string to the REST request’s URL.

For example, if we want to retrieve only the Cloud Account with the name “aprovc1.automationpro.lan”, we can modify the URL as follows:

“`

https://vra-8-3-instance/rest/cloud-accounts?name=aprovc1.automationpro.lan

“`

By appending the query string “name=aprovc1.automationpro.lan” to the URL, we can filter out all results that do not match this query and return only the single result that matches our criteria.

If you’re interested in learning more about the available filters and how to use them, you can check out the API documents hosted on your vRA 8.3 instance. These documents provide detailed information on the available filters, their syntax, and examples of how to use them.

In conclusion, using RESTful APIs in vRA 8.x is a powerful way to automate various tasks and access endpoints. By understanding the basics of REST and how to use software packages like Code Stream, you can simplify the process of communicating with vRA 8.x and perform tasks like authenticating requests, obtaining tokens, and filtering results using query strings.

Building a New Centos7 Template with Packer and Code Stream

In this post, we will detail a simple Code Stream pipeline that builds a new Centos7 template using Packer. We will also cover how to configure Packer to create templates for your lab environment.

To begin, we will make a few assumptions:

* You have a basic understanding of Packer and Code Stream.

* You have the necessary tools installed on your system, including Docker and Git.

* You have a GitHub repository containing the Packer build definition and kickstart file for the Centos7 build.

To get started, we will need to download Packer and create a new pipeline in Code Stream. We can do this by following these steps:

1. Open Code Stream and click on the “New Pipeline” button.

2. Give your pipeline a name and select “Docker” as the runtime.

3. Click on the “Inputs” tab and add three input parameters: GIT_REPOSITORY_PATH, PACKER_FILE, and PACKER_URI. These inputs will be used to configure Packer and obtain the necessary files for the build process.

4. Click on the “Configure Workspace” button and select the Docker radio option for the Auto inject parameters parameter. This will ensure that the input parameters we configure are injected into our Docker container when our pipeline executes.

5. Save your pipeline configuration.

Next, we will need to provide default values for our input parameters. To do this, we can add three variables to obfuscate the values that our pipeline will use:

1. SECRETYour projectssh_password (the password that will be used to SSH into your Centos7 VM)

2. SECRETYour projectvcenter_password (the password for your adminstrator@vsphere.local account)

3. SECRETYour projectGithub Access Token (the access token generated on Github)

We can add these variables by clicking the “New Variable” button in the Configuration section and adding the details below:

Type: Project Name

Value: Your projectssh_password

Type: Project Name

Value: Your projectvcenter_password

Type: Project Name

Value: Your projectGithub Access Token

Once we have configured our pipeline and variables, we can move on to the next stage. We will create a new stage for each task, grouping related tasks together to achieve our end goal of building a new Centos7 template.

The main purpose of this task is to download and unzip Packer using a new variable. We will add some bash code to download Packer using a new variable. This task is very straightforward.

Next, we will create a new stage for the Packer validate switch. This stage will carry out our instructions and ultimately generate our new VM template. Before this, we will carry out a find and replace function to insert the root password into the Centos7 kickstart file. We will also download and add a package into our Docker container, xorriso. This package allows Packer to create our kickstart ISO file on the fly.

You should now be in a position to execute your pipeline and build your first template. Congratulations! In future posts, I will look to improve on this process.

Integrating Puppet Enterprise with vRA 8.3: A Step-by-Step Guide

If you’re looking to integrate Puppet Enterprise with VMware vRealize Automation (vRA) 8.3, you might have encountered some obstacles in the process. In this blog post, we’ll walk you through the necessary steps to configure the integration between Puppet Enterprise and vRA 8.3. Note that these instructions are based on a freshly installed Linux VM for the Puppet primary server install, so make sure to follow them in order before installing Puppet Enterprise.

Step 1: Update CentOS

Before we begin, ensure that your CentOS is up to date by running the following command:

sudo dnf -y update

Step 2: Install Utilities

Next, install the required utilities by running the following commands:

sudo dnf -y install wget curl vim nano open-vm-tools bash-completion

Step 3: Set Hostname

Ensure that your hostname is set correctly by running the following command:

sudo hostnamectl set-hostname hostname_fqdn_format

Step 4: Create User for Integration

Create a user for the integration between Puppet and vRA by running the following commands:

sudo adduser account_name

Set password for the account by running:

sudo passwd account_name

Add the user to the wheel group by running:

sudo usermod -aG wheel account_name

Step 5: Disable Firewall

Disable the firewall by running:

sudo systemctl stop firewalld

sudo systemctl disable firewalld

Step 6: Create File in /etc/sudoers.d/ Directory

Create a file in the /etc/sudoers.d/ directory with the following contents:

account_name ALL=(root) NOPASSWD:/opt/puppetlabs/bin/puppet node purge *

account_name ALL=(root) NOPASSWD:! /opt/puppetlabs/bin/puppet node purge *[[:blank:]]]*

account_name ALL=(root) NOPASSWD:/opt/puppetlabs/bin/puppet config print *

account_name ALL=(root) NOPASSWD:! /opt/puppetlabs/bin/puppet config print *[[:blank:]]]*

account_name ALL=(root) NOPASSWD:/opt/puppetlabs/bin/facter -p puppetversion

account_name ALL=(root) NOPASSWD:/opt/puppetlabs/bin/facter -p pe_server_version

account_name ALL=(root) NOPASSWD:/opt/puppetlabs/bin/puppet agent -t

account_name ALL=(root) NOPASSWD:/bin/kill -HUP *

account_name ALL=(root) NOPASSWD:! /bin/kill -HUP *[[:blank:]]]*

account_name ALL=(root) NOPASSWD:/etc/puppetlabs/puppet/ssl/ca/ca_crl.pem

Step 7: Download Puppet Enterprise

Download the latest version of Puppet Enterprise from the Puppet website by running:

sudo curl -JLO ‘https://pm.puppet.com/cgi-bin/download.cgi?dist=el&rel=8&arch=x86_64&ver=latest’

Step 8: Install Puppet Enterprise

Extract the installer files by running:

sudo tar -xf *puppet-enterprise*.tar.gz

Install Puppet Enterprise by running:

cd ./puppet-enterprise*/

sudo ./puppet-enterprise-installer

Step 9: Set Console Password

Set the console password for your Puppet infrastructure by running:

sudo puppet infrastructure console_password

Step 10: Execute the Puppet Agent (twice)

Execute the Puppet agent twice to complete the integration by running:

puppet agent -t

puppet agent -t

At this point, you are now able to configure the integration in vRA. Specify the account to use as the one you configured above as account_name and make sure to tick the ‘Use Sudo commands for this user‘ tickbox.

We hope these instructions have helped you integrate Puppet Enterprise with vRA 8.3 successfully!

I recently had some fun and games with vRA 8.2’s extensibility capabilities, particularly with PowerShell support for vRA actions. I wanted to see what I could break, so I tried to obtain the ‘userName’ of the requester from the metadata section using PowerShell. However, no matter what I did, the metadata always remained empty.

I then discovered that using the Flow type of action can be quite handy. This allows me to chain multiple actions together and pass output from one action to another by updating values. What I didn’t realize at first was that I could also add new properties to the payload with a value, use it in the next action, and then remove it so that there is no ‘secret data’ left over on the deployed resource properties.

Here is an example of a simple PowerShell action I wrote:

The $payload that is injected into the function contains all the information and properties as of the time of the subscribed event. I create a new object, copy all of the payload to it. I then pass the new payload, stored as $outputs to the Add-Member PowerShell function. I add a new property called ‘Testing’ and set a value on it of ‘Michael.’ Finally, I return the $outputs, sending this object as an output that will be used as the payload into the next action in the flow.

In the second action, I again take the $payload and make a new object and copy all of its properties and values. To prove that the previous action’s output contains the new ‘Testing’ property, I write out the value to the console [log]. Finally, I remove the property from my $outputs object and return it.

When the blueprint is requested following the action executions, you can clearly see our new property ‘Testing’ printed out to the screen. However, when we look at the properties of the deployed resource once deployment is complete, the property is not shown.

This demonstrates how we can add new properties to the payload and use them in subsequent actions without leaving any ‘secret data’ behind on the deployed resource properties. Additionally, this shows how we can chain multiple actions together using the Flow type of action and pass output from one action to another by updating values.

I hope that someone out there can tell me what I have done wrong! Please let me know if you have any answers on a postcard.

As I embarked on my latest project, deploying the NSX-T manager in my lab, I quickly realized that something had gone awry. Despite following the instructions to the letter, the appliance had not installed properly. The services were not started correctly, and there was no web UI to speak of. To make matters worse, I noticed errors in the console about not setting the password for the admin and root accounts.

As I delved deeper into the issue, I realized that the problem lay with my own mistake. I had chosen a password that was not complex enough. When I logged in using the default username and password, I was informed that it was not complex enough! It was a good reminder to always read the instructions on the screen, especially when it comes to critical aspects such as passwords.

The OVA import wizard will let you proceed regardless, but this can lead to issues down the line. It’s important to take the time to set up the password correctly from the outset, rather than rushing through the process and risking potential security breaches.

As a CIO at Sonar and Automation Practice Lead at Xtravirt, I understand the importance of proper planning and execution in IT projects. It’s easy to get caught up in the excitement of a new project, but it’s essential to take a step back and ensure that all aspects are properly configured before moving forward.

In this case, I should have taken more time to carefully set up the password for the admin and root accounts. By doing so, I could have avoided the errors and issues that arose during the deployment process. It’s a valuable lesson in the importance of paying attention to detail and following instructions carefully, especially when it comes to critical aspects such as security.

As a guitarist in The Waders, I also understand the value of patience and attention to detail in creating music. Just as a well-crafted song requires careful planning and execution, so too does a successful IT project. By taking the time to properly set up the NSX-T manager, I can ensure that my project is successful and secure, just like a well-rehearsed song.

In conclusion, when deploying the NSX-T manager, it’s essential to pay attention to detail and follow instructions carefully, especially when it comes to critical aspects such as security. By doing so, you can avoid errors and issues down the line and ensure that your project is successful and secure. Remember, READ THE INSTRUCTIONS ON THE SCREEN!
