Configuring the Dukes Bank Sample Application Blueprint

Configuring the Dukes Bank Sample Application Blueprint

In the previous part importing steps of Dukes Bank Sample Application Blueprint were described. Now it’s time to perform additional configurations steps to makes it works. (If you thought that you will be able to request sample three-tier app out of the box after you import it, you were wrong! Do not worry I overinterpreted it also when first seeing it during a training long time ago ;))

But going back to vRA Dukes Bank App – after successful import you have to configure the blueprint.

First of all you must prepare Centos template for the blueprint. There are following prerequesities:

  1. Install Guest Agent.
    • Guest agent can be downloaded from https://your_vra_FQDN:5480/software. You can download it on your mgmt station and then transfer to template machine or directly from template using following command:  #wget –no-check-certificate https://your_vra_FQDN:5480/software/download/prepare_vra_template.sh . After that it have to be made executable e.g # chmod u+x prepare_vra_template.sh and simply run it. A few information must be provided1gugent2gugent3gugent
    • SeLinux feature have to be disabled. without disabling it you can expect following error during deployment.selinux2To disable SELinux rom the command line, you can edit the /etc/sysconfig/selinux file. This file is a symlink to /etc/selinux/config. Changing the value of SELINUX or SELINUXTYPE changes the state of SELinux and the name of the policy to be used the next time the system boots. Simply change it to disabled and save settings.[root@host2a ~]# cat /etc/sysconfig/selinux
      # This file controls the state of SELinux on the system.
      # SELINUX= can take one of these three values:
      # enforcing – SELinux security policy is enforced.
      # permissive – SELinux prints warnings instead of enforcing.
      # disabled – SELinux is fully disabled.
      SELINUX=permissive
      # SELINUXTYPE= type of policy in use. Possible values are:
      # targeted – Only targeted network daemons are protected.
      # strict – Full SELinux protection.
      SELINUXTYPE=targeted
  2.  When your tepmlate is up and ready you have to make additional changes in blueprint. ( Do not forget to run data collection to see current state of your template/snapshot)
    • Modify the blueprint machine specs for each node:
      •Template Name / Customization Spec
      •Reservation Policy
      •Machine Prefix
      •Edit the property http_node_ips in Apache Load Balancer and Binding = Yes
    • In case you use DHCP address allocation you must add a dependency from Load Balancer Node machine to App Server node. Simply put an arrow to connect them.

 

That’s it now you are ready to resuest and test your sample Dukes Bank Application.

 

 

 

VCIX6-CMA – another goal achieved

VCIX6-CMA – another goal achieved

It is almost a tradition or habbit for me to share my experience about VMware exmination taken so far.

Well, it happened, I eventually passed the VCAP6-CMA Design exam which together with previos passed VCAP6-CMA Deploy exam gave me VCIX6-CMA tiltle and badge. It looks like this:vmware_milestone_CMA_expert-e1502128382899Nothing special, it was not an easy way to get it, though!

The biggest problem with that IMHO is that it is and old version which is based on vRA 6.X, whilst we currently have 7.3 available since sometime already..

Besides that I experienced a few additional problems with Pearson Vue/ VMware certification engine which made me to take it each exam more than once.  And still it’s version 6 and a few days ago VMware announced new versions of VCAP certs, however that’s only Design ones.

There is nothing more to do right nowe, just prepare for new version 🙂 which as a certification addicted I will for sure try to gain.

P.S. to be honest VCAP6-CMA Design exam was the most tricky one I have ever took so far.

 

Importing the Dukes Bank sample application blueprint – Introduction to vRealize CloudClient

Importing the Dukes Bank sample application blueprint – Introduction to vRealize CloudClient

Have you just installed the vRealize Automation in your lab and do not know how to start the journey with services? The Dukes Bank for vSphere application might be a perfect start for you!

But what is that mystery Dukes Bank application ? It is not widely known that there are let’s say “embedded” samples of multi-tiered vRealize Automation blueprints  that includes multiple machine components with networking and software components.

The reason that it is not known by many is that they are not available ad-hoc after installation, you will not see them inside your catalog. To publish these services in Tenant’s catalog you need to import and configure it first. Bellow I described the procedure how to import and publish these services, in another article you will find out how to configure it.

The ZIP file for Dukes Bank sample application blueprint is include on the vRA appliance, however to import it you have to use vRealize Cloud Client which can be downloaded here.

vRealize CloudClient is a CLI utility that provides verb-based access with a unified interface across vRA APIs, it is available since vRA version 6.2. The purpose of CloudClient tool is to create a layer of abstraction between vRA and end consumer, I mean Administrator of vRA to increase the ease by which he is able to run automated actions against vRA. It is worth to meantion that this tool is not a REST or SOAP API. It uses the vRA API instead.

Just to list a few of use cases for vRA API:

  • Reporting;
  • Monitoring and troubleshooting;
  • Change request system;
  • Operation scripts;
  • Migration between environments;
  • Creating reservations;
  • Creating business groups;
  • Creating entitlements;
  • Other management tasks.

Going back to the point, after downloading the CloudClient you can run it from Windows as well as Linux, however I realized that if you want to import Dukes Bank application you must run it from vRA appliance.

Whilst running it from Windows I received an error like below:

CC1

Well, my recommendation is to copy CloudClient into vRA appliance and run it using cloudclient.sh.

Before you will be ready to import Dukes Bank you need to download the package using following command:

#wget –no-check-certificate https://YOUR_vRA_URL:5480/blueprints/dukesbankappforv sphere.zip

Then you could copy it to /tmp for easier navigation.

CC2

When you have the package it is hight time to run CloudClient and connect to vRA using following command:

vra login userpass –user tenant_admin_username –tenant your_tenant_name –server https://vra.cloud.local –password your_pass

CC3

After successful login you can validate and import the package.

To validate use the following command with dry-run:

vra content import –path /DukesBankAppForvSphere.zip –dry-run true –resolution OVERWRITE

NOTE! Pay attention to capital letters, it is case sensitive.

To import the package change the argument of dry-run to false:

vra content import –path /DukesBankAppForvSphere.zip –dry-run false –resolution OVERWRITE

CC4

And that is it, the first step to deploy sample blueprints is done. You can validate that these packages are imported by from your vRA console. You need to log in as a user with software and infrastructure architect privileges. The Dukes Bank blueprints and software components on the Design > Blueprints tab and the Design > Software Components tab.
