TCA on vUnhandledException

TCA 2.1 Systemsettings add-on stuck in Processing status

Sun, 31 Jul 2022 19:45:30 +0200

When deploying a v2 cluster you may notice that an input field for the capv user password is missing. To be able to set a password you will have to deploy the systemsettings cluster add-on, however with following the default wizard settings the add-on deployment gets stuck.

Not only does the add-on deployment get stuck, but also none of the settings get applied to the actual cluster. The main symptom can be seen in the picture below.

TCA 2.1 What's new - Kubernetes Cluster Diagnosis

Wed, 27 Jul 2022 22:56:02 +0100

Telco Cloud Automation 2.1 introduced a new feature to be able to perform better health checks for deployed Kubernetes clusters. This post will explore that functionality.

The diagnosis can be run against management clusters, workload clusters or specific nodepools. When going into the details of each of those objects you will find a Diagnosis tab like in the picture below.

When you first run this you obviously would not have results listed, but still have the button to "Run Diagnosis". When that button is clicked a new wizard pops up which lets you choose if you only want to run a subset of tests (you can simply multi-select by clicking on each of the options you want) or if you leave the field blank (it does read optional) all of the tests at once as shown in the figure below.

As the amount of features delivered by Telco Cloud Automation increases there is going to be an impact on the sizing of the appliances. This post is going to explore what exactly has changed between 2.0 and 2.1 from a sizing perspective.

The following table summarizes the sizing requirements for each of the components in a production based deployment for Telco Cloud Automation 2.0. You would either choose a VM based or a CNA based deployment.

TCA 2.1 What's new - CaaS Management Cluster options

Mon, 25 Jul 2022 19:50:16 +0100

While most of of the new features on the CaaS side in Telco Cloud Automation are utilized by Workload Clusters we will explore some new functionality for Management cluster deployemts in this post.

Telco Cloud Automation 2.1 introduces a new v2 CaaS cluster api version. New functionality includes the following:

AKO Operator Support
TKG extensions for Prometheus and Fluentbit
Stretch cluster support in the UI
A new user interface
IPv6 support

Not everything will be reflected on management clusters which still use the v1 API and UI version but most of the features will be covered in this post (except for Prometheus, Fluentbit and AKOO which will get their own blog post shortly and the new user interface which isn't supported for Management clusters today).

TCA 2.1 What's new - AD authentication

Telco Cloud Automation 2.1 was released last week and this post will explore the newly introduced feature to directly access Active Directoy authentication via the TCA Manager.

Release Notes description

The release notes cover this topic in a rather brief statement:

1Integration with external Active Directory system for user authentication, in addition to vCenter Server authentication.

I will concentrate on the configuration for the virtual machine form factor of Telco Cloud Automation here, but the steps on how to configure this functionality within the Cloud Native deployment of Telco Cloud Automation can be found in the installation guide, you are looking to modify the "tcaMgr" section accordingly.
