Cleanup Failed Tasks in SDDC Manager

I was chatting with my colleague Paudie O’Riordan yesterday about PowerVCF as he was doing some testing internally and he mentioned that a great addition would be to have the ability to find, and cleanup failed tasks in SDDC Manager. Some use cases for this would be, cleaning up an environment before handing it off to a customer, or before recording a demo etc.

Currently there isnt a supported public API to delete a failed task so you have to run a curl command on SDDC Manager with the task ID. So getting a list of failed tasks and then running a command to delete each one can take time. See Martin Gustafson’s post on how to do it manually here.

I took a look at our existing code for retrieving tasks (and discovered a bug in the logic that is now fixed in PowerVCF 2.1.5!) and we have the ability to specify -status. So requesting a list of tasks with -status “failed” returns a list. So i put the script below together to retrieve a list of failed tasks, loop through them and delete them. The script requires the following inputs

  • SDDC Manager FQDN. This is the target that is queried for failed tasks
  • SDDC Manager API User. This is the user that is used to query for failed tasks. Must have the SDDC Manager ADMIN role
  • Password for the above user
  • Password for the SDDC Manager appliance vcf user. This is used to run the task deletion. This is not tracked in the credentials DB so we need to pass it.

Once the above variables are populated the script does the following:

  • Checks for PowerVCF (minimum version 2.1.5) and installs if not present
  • Requests an API token from SDDC Manager
  • Queries SDDC Manager for the management domain vCenter Server details
  • Uses the management domain vCenter Server details to retrieve the SDDC Manager VM name
  • Queries SDDC Manager for a list of tasks in a failed state
  • Loops through the list of failed tasks and deletes them from SDDC Manager
  • Verifies the task is no longer present

Here is the script. It is also published here if you would like to enhance it

Site Protection & Disaster Recovery for VMware Cloud Foundation Validated Solution

Along with the release of VMware Cloud Foundation 4.3.1, we are excited to announce the general availability of the Site Protection & Disaster Recovery for VMware Cloud Foundation Validated Solution. The solution documentation, intro and other associated collateral can be found on the Cloud Platform Tech Zone here.

The move from VMware Validated Designs to VMware Validated Solutions has been covered by my team mate Gary Blake in detail here so I wont go into that detail here. Instead I will concentrate on the work Ken Gould and I (along with a supporting team) have been working to deliver for the past few months.

The Site Protection & Disaster Recovery for VMware Cloud Foundation Validated Solution includes the following to deliver an end-to-end validated way to protect your mission critical applications. You get a set of documentation that is tailored to the solution that includes: design objectives, a detailed design including not just design decisions, but the justifications & implications of those decisions, detailed implementation steps with PowerShell alternatives for some steps to speed up time to deploy, operational guidance on how to use the solution once its deployed, solution interoperability between it and other Validated Solutions, an appendix containing all the solution design decisions in one easy place for review, and finally, a set of frequently asked questions that will be updated for each release.

Disaster recovery is a huge topic for everyone lately. Everything from power outages to natural disasters to ransomware and beyond can be classed as a disaster, and regardless of the type of disaster you must be prepared. To adequately plan for business continuity in the event of a disaster you must protect your mission critical applications so that they may be recovered. In a VMware Cloud Foundation environment, cloud operations and automation services are delivered by vRealize Lifecycle Manager, vRealize Operations Manager & vRealize Automation, with authentication services delivered by Workspace ONE Access.

To provide DR for our mission critical apps we leverage 2 VCF instances with NSX-T federation between them. The primary VCF instance runs the active NSX-T global manager and the recovery VCF instance runs the standby NSX-T global manager. All load balancing services are served from the protected instance, with a standby load balancer (disconnected from the recovery site NSX Tier-1 until required, to avoid IP conflicts) in the recovery instance. Using our included PowerShell cmdlets you can quickly create and configure the standby load balancer to mimic your active load balancer, saving you a ton of manual UI clicks.

In the (hopefully never) event of the need to failover the cloud management applications, you can easily bring the standby load balancer online to enable networking services for the failed over applications.

Using Site recovery Manager (SRM) you can run planned migrations or disaster recovery migrations. With a single set of SRM recovery plans, regardless of the scenario, you will be guided through the recovery process. In this post I will cover what happens in the event of a disaster.

When a disaster occurs on the protected site (once the panic subsides) there are a series of tasks you need to perform to bring those mission critical apps back online.

First? Fix the network! Log into the passive NSX Global Manager (GM) on the recovery site and promote the GM to Active. (Note: This can take about 10-15 mins)

To cover the case of an accidental “Force Active” click..we’ve built in the “Are you absolutely sure this is what you want to do?” prompt!

Once the promotion operation completes our standby NSX GM is now active, and can be used to manage the surviving site NSX Local Manager (LM)

Once the recovery site GM is active we need to ensure that the cross-instance NSX Tier-1 is now directing the egress traffic via the recovery site. To do this we must update the locations on the Tier-1. Navigate to GM> Tier-1 gateways > Cross Instance Tier-1. Under Locations, make the recovery location Primary.

The next step is to ensure we have an active load balancer running in the recovery site to ensure our protected applications come up correctly. To do this log into what is now our active GM, select the recovery site NSX Local Manager (LM), and navigate to Networking > Load Balancing. Edit the load balancer and attach it to the recovery site standalone Tier-1.

At this point we are ready to run our SRM recovery plans. The recommended order for running the recovery plans (assuming you have all of the protected components listed below) is as follows. This ensures lifecycle & authentication services (vRSLCM & WSA) are up before the applications that depend on them (vROPS & vRA)

  • vRSLCM – WSA – RP
  • Intelligent Operations Management RP
  • Private Cloud Automation RP

I’m not going to go through each recovery plan in detail here. They are documented in the Site Protection and Disaster Recovery Validated Solution. In some you will be prompted to verify this or that along the way to ensure successful failover.

The main thing in a DR situation is, DO NOT PANIC. And what is the best way to getting to a place where you DO NOT PANIC? Test your DR plans…so when you see this…

Your reaction is this…

BookReview: Rest — Fresh Perception

Trust the plan…test the plan…relax…you have a plan!

Hopefully this post was useful..if you want to learn more please reach out in the comments…if you’re attending VMworld and would like to learn more or ask some questions, please drop into our Meet The Experts session on Thursday.

Take a look at Ken’s post on the Planning & Preparation Workbook for this validated solution for more details.

Part 2: Working With the SRM VAMI API : Replacing the Appliance Certificate

In Part 1 of this series we saw how to retrieve a sessionId from the Site Recovery Manager VAMI interface using Postman & Powershell. In this post we will use that sessionId to replace the appliance SSL certificate using the API. To start we again use the VAMI UI to inspect the endpoint URL being used for certificate replacement by doing a manual replacement. In this case the URL is:

https://sfo-m01-srm01.sfo.rainpole.io:5480/configure/requestHandlers/installPkcs12Certificate

Site Recovery Manager expects the certificate in P12 format so I used CertGen to create the cert format needed. When using the UI you browse to the cert file and it uploads in the browser along with the certificate passphrase. Behind the scenes it is then base64 encoded, so you need to do this before using the API.

# Base64 encoded the p12 file

$certFile = ".\sfo-m01-srm01.4.p12"

$base64string = [Convert]::ToBase64String([IO.File]::ReadAllBytes($certFile))


$body = '{
"certificateContent": "'+$base64string+'",
"certificatePassword": "'+$certPassword+'"
}'

#Create the required headers using the sessionId

$headers = @{"Content-Type" = "application/json"}
$headers.Add("dr.config.service.sessionid", "$sessionId")


$uri = "https://sfo-m01-srm01.sfo.rainpole.io:5480/configure/requestHandlers/installPkcs12Certificate"


Invoke-RestMethod -Method POST -Uri $uri -Headers $headers -body $body

And there you have it..your appliance cert replaced via the API.

Part 1: Working With the SRM VAMI API : Retrieving a Session ID

I’ve recently been doing a lot of work with VMware Site Recovery Manager (SRM) and vSphere Replication (vSR) with VMware Cloud Foundation. Earlier this year we (Ken Gould & I) published an early access design for Site Protection & Recovery for VMware Cloud Foundation 4.2. We have been working to refresh & enhance this design for a new release. Part of this effort includes trying to add some automation to assist with the manual steps to speed up time to deploy. SRM & vSR do not have publicly documented VAMI APIs so we set about trying to automate the configuration with a little bit of reverse engineering.

As with most APIs, whether public or private, you must authenticate before you can run an API workflow, so the first task is figuring out how the authentication to perform a workflow works. Typically, if you hit F12 in your browser you will get a developer console that exposes what goes on behind the scenes in a browser session. So to inspect the process, use the browser to perform a manual login, and review the header & response tabs in the developer view. This exposes the Request URL to use, the method (POST) and the required headers (accept: application/json)

The Response tab shows a sessionId which can be used for further configuration API calls in the headers as dr.config.service.sessionid

So with the above information you can use an API client like Postman to retrieve a sessionId with the URL & headers like this

And your VAMI admin user and password in JSON format in the body payload

You can also use the information to retrieve a sessionId using PowerShell

$headers = @{"Content-Type" = "application/json"}
$uri = "https://sfo-m01-srm01.sfo.rainpole.io:5480/configure/requestHandlers/login"
$body = '{"username": "admin","password": "mypassword"}'

$request = Invoke-RestMethod -Method POST -Uri $uri -Headers $headers -body $body

$sessionID = $request.data.sessionId

$sessionId

Keep an eye out for additional posts where we will use the sessionId to perform API based tasks

Checking Password Expiry For VMware Cloud Foundation Management Components

Within a VMware Cloud Foundation instance, SDDC Manager is used to manage the lifecycle of passwords (or credentials). While we provide the ability to rotate (either scheduled or manually) currently there is no easy way to check when a particular password is due to expire, which can lead to appliance root passwords expiring, which will cause all sorts of issues. The ability to monitor expiry is something that is being worked on, but as a stop gap I put together the script below which leverages PowerVCF and also a currently undocumented API for validating credentials.

The script has a function called Get-VCFPasswordExpiry that accepts the following parameters

  • -fqdn (FQDN of the SDDC Manager)
  • -username (SDDC Manager Username – Must have the ADMIN role)
  • -password (SDDC Manager password)
  • -resourceType (Optional parameter to specify a resourceType. If not passed, all resources will be checked. If passed (e.g. VCENTER) then only that resourceType will be checked. Supported resource types are

PowerVCF is a requirement. If you dont already have it run the following

Install-Module -Name PowerVCF

The code takes a while to run as it needs to do the following to check password expiry

  • Connect to SDDC Manager to retrieve an API token
  • Retrieve a list of all credentials
  • Using the resourceID of each credential
    • Perform a credential validation
    • Wait for the validation to complete
    • Parse the results for the expiry details
    • Add all the results to an array and present in a table (Kudos to Ken Gould for assistance with the presentation of this piece!)

In this example script I am returning all non SERVICE user accounts regardless of expiry (SERVICE account passwords are system managed). You could get more granular by adding something like this to only display accounts with passwords due to expire in less than 14 days

if ($validationTaskResponse.validationChecks.passwordDetails.numberOfDaysToExpiry -lt 14) {
               Write-Output "Password for username $($validationTaskResponse.validationChecks.username) expires in $($validationTaskResponse.validationChecks.passwordDetails.numberOfDaysToExpiry) days"
           }

Here is the script content. As always feedback is welcome. Also posted in Github here if anyone wants to fork and improve https://github.com/LifeOfBrianOC/Get-VCFPasswordExpiry

VMware Cloud Foundation Bringup With Signed Certs on ESXi Hosts

Traditionally VMware Cloud Foundation (VCF) has followed the hybrid approach when it comes to SSL certificate management. Hybrid mode essentially means using CA signed certs for the vCenter Server machineSSL cert, and VMCA signed certs for the solution user certs. In this mode, ESXi host certs are VMCA managed also. You then have the option to integrate with an external Microsoft CA or continue to use VMCA for all certs. If you decide to integrate with a Microsoft CA, ESXi host certs remain VMCA managed. This is not always ideal as some customers require all components on the network to be signed by a known & trusted CA. Up until the recent 4.1 VMware Cloud Foundation (VCF) release it was not possible to use custom CA signed certs on your ESXi hosts, as hybrid mode would overwrite your CA signed ESXi certs with VMCA signed certs. There is a great blog post here on how to manually enable CA signed certs here but with VCF 4.1 it is now supported to do this via the API during bringup. The procedure is as follows:

 

  1. Install the ESXi hosts that will be used for bringup with the ESXi version on the Bill Of Materials for 4.1
  2. Install your custom CA signed certs on each host that will be used for the management domain
    1. Log in to the ESXi Shell, either directly from the DCUI or from an SSH client, as a user with administrator privileges.
    2. In the directory /etc/vmware/ssl, rename the existing certificates using the following commands.
      mv rui.crt orig.rui.crt 
      mv rui.key orig.rui.key
      
    3. Copy the certificates that you want to use to /etc/vmware/ssl.
    4. Rename the new certificate and key to rui.crt and rui.key.
    5. Restart the host management agents by running the following commands
 /etc/init.d/hostd restart /etc/init.d/vpxa restart 

Repeat the above steps for all management domain hosts

To ensure that SDDC Manager is aware that you are using custom certs you need to add a flag in the bringup json along with the PEM encoded signing chain certificate, so that it is added to the SDDC Manager keystore. This will ensure the certificates are trusted. The API guide for 4.1 provides an example json spec here. Pay particular attention to this section

securitySpec" : {
"esxiCertsMode" : "One among:Custom, VMCA",
"rootCaCerts" : [ {
"alias" : "string",
"certChain" : [ "string" ]
} ]
}

So to enable support for signed certs you would set this section as follows (Substituting your signing CA chain)

 securitySpec" : { 
"esxiCertsMode" : "Custom", 
"rootCaCerts" : [ { 
"alias" : "Rainpole-CA", 
"certChain" : [ "-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----" ] } ] } 

 

 

You can then follow the steps outlined in the API guide to deploy the management domain using the Cloud Builder API. Note that once custom mode is enabled, all future workload domains that you create must also use signed certs.

Announcing VMware Skyline Support for VMware Cloud Foundation 4.1

VMware Skyline™ is a proactive support service aligned with VMware Global Support Services. VMware Skyline automatically and securely collects, aggregates, and analyzes product usage data which proactively identifies potential problems and helps VMware Technical Support Engineers improve the resolution time.

With the release of VMware Skyline collector 2.6, it is now supported to add VMware Cloud Foundation awareness to Skyline advisor to ensure that Skyline findings and recommendations take into account, and do not violate the VMware Cloud Foundation design or Bill Of Materials (BOM). To enable this integration you add the SDDC Manager from each Cloud Foundation instance. When a vCenter Server, NSX-T Manager, & vRealize Operations Manager from that VMware Cloud Foundation instance is added they are automatically associated with the SDDC Manager and tagged for VCF based recommendations in Skyline Advisor.

 

To add Cloud Foundation to Skyline you need to do the following

Add a user in SDDC Manager and assign the VMware Cloud Foundation Viewer role.

Configure the VMware Skyline Collector to add the SDDC Manager instance by entering the FQDN & credentials for the above user

Once added SDDC Manager will show in the collector inventory view

 

Logging into Skyline Advisor in VMware Cloud Services you now see VMware Cloud Foundation listed as part of the inventory on the dashboard.

Navigating to the Inventory tab enables you to expand the VMware Cloud Foundation view to see the associated Cloud Foundation inventory

  1. VMware Cloud Foundation
  2. SDDC Manager
  3. Management Domain
  4. Workload Domain(s)
  5. vRealize Operations Manager

 

Skyline findings and recommendations for these associated inventory items will now be surfaced as solution-based Proactive Findings.

Get started with Skyline here https://docs.vmware.com/en/VMware-Skyline/index.html

Where Are My VMware Cloud Foundation Logs?

From time to time we all need to look at logs, whether its a failed operation or to trace who did what when. In VMware Cloud Foundation there are many different logs, each one serving a different purpose. Its not always clear which log you should look at for each operation so here is a useful reference table.

PowerVCF 2.0 Authentication Changes

One of the many major enhancements in VMware Cloud Foundation 4.0 is a switch from basic authentication to token based authentication for the VCF API.

Basic authentication is a header field in the form of Authorization: Basic <credentials>, where credentials is the base64 encoding of a username and password. The credentials are not encrypted, therefore Basic Authentication is not the industry standard for API authentication.

VCF 4.0 has moved to using token based authentication (JWT Tokens to be exact) for securing the API. The token implementation is as follows:

  1. An authorized user executes a POST API call to /v1/tokens
  2. The response contains an access token and a refresh token
    1. The access token is valid for 1 hour
      1. The access token is passed in every API call header in the form of Authorization: Bearer <access token>
    2. The refresh token is valid for 24 hours
      1. The refresh token is used to request a new access token once it has expired

PowerVCF 2.0 abstracts all of this in the following way:

  • An authorized user connects to SDDC Manager to request the tokens by running:

Connect-VCFManager -fqdn sfo-vcf01.sfo.rainpole.io -username svc-vcf-api@rainpole.io -password VMw@re1!

  • The access & refresh tokens are stored in memory and used when running subsequent API calls. As each API call is executed PowerVCF checks the expiry of the access token. If the access token is about to expire, it uses the refresh token to request a new access token and proceeds with the API call. So the user does not need to worry about token management.

We have also introduced roles that can be assigned to users. Initially we have ADMIN & OPERATOR, with more roles planned for a future release.

ADMIN = Full Administrator Access to all APIs

OPERATOR = All Access except Password Management, User Management, Backup Management

To request an API token you must have a user account that is assigned either the ADMIN or OPERATOR role in SDDC Manager. The default administrator@vsphere.local user is assigned the ADMIN role during bringup but it is advisable to add additional users for performing day to day tasks.

Once you have a user added you can then authenticate with SDDC Manager to retrieve your access & refresh tokens.

Tip: You can connect using the administrator@vsphere.local user to add new users using PowerVCF. You can use the New-VCFUser PowerVCF cmdlet to create the user and assign a role like so:


Connect-VCFManager -fqdn sfo-vcf01.sfo.rainpole.io -username administrator@vsphere.LOCAL -password VMw@re1!

New-VCFUser -user vcf-admin@rainpole.io -role ADMIN

Once your user is configured PowerVCF will do the rest when it comes to managing the API access tokens.
