Sitecore AKS - Collection shard cluster health check completed with status Unhealthy and Health check for shard cluster is failed.

The Problem

While running the installation steps for setting up Sitecore XP in AKS, we found that the CM/CD pods are not running. This was primarily due to the fact that CM/CD pods were waiting on other pods like xDBsearch to come to running state due to wait-initialization. After waiting for significant time, we found that xDBsearch pod is not coming up and it probably has an issue. Ran kubectl logs command to check xdbsearch logs and found below entries - 



The Solution

This error definitely implied that the shard databases have some issue. We deleted the shard databases and ran the init job again. When the init job completes, it is advisable to check logs by running kubectl logs command. This will inform if the job was successful or did it errored out at some point.

Once the shard databases were recreated, we recreated the pods and this time the xdbsearch pods came up fine. Thanks for reading :)

Sitecore PowerShell Script to create all language versions for an item from en version

  We have lots of media items and our business wants to copy the data from en version of media item to all other language versions defined in System/Languages. This ensures that media is available in all the languages. So, we created the below powershell script to achieve the same -  #Get all language versions defined in System/Languages $languages = Get-ChildItem /sitecore/System/Languages -recurse | Select $_.name | Where-Object {$_.name -ne "en"} | Select Name #Ensuring correct items are updated by comparing the template ID  $items = Get-ChildItem -Path "/sitecore/media library/MyProjects" -Recurse | Where-Object {'<media item template id>' -contains $_.TemplateID} #Bulk update context to improve performance New-UsingBlock (New-Object Sitecore.Data.BulkUpdateContext) { foreach($item in $items){    foreach($language in $languages){ $languageVersion = Get-Item -Path $item.Paths.Path -Language $language.Name #Check if language versi...

Make Sitecore instance faster using Roslyn Compiler

When we install the Sitecore instance on local, the first load is slow. After each code deploy also, it takes a while for the Sitecore instance to load and experience editor to come up. For us, the load time for Sitecore instance on local machines was around 4 minutes. We started looking for ways to minimize it and found that if we update our Web.config to use Roslyn compiler and include the relevant Nugets into the project, our load times will improve. We followed the simple steps - Go to the Project you wish to add the NuGet package and right click the project and click 'Manage NuGet Packages'. Make sure your 'Package Source' is set to nuget.org and go to the 'Browse' Tab and search Microsoft.CodeDom.Providers.DotNetCompilerPlatform. Install whichever version you desire, make sure you note which version you installed. You can learn more about it  here . After installation, deploy your project, make sure the Microsoft.CodeDom.Providers.DotNetCompilerPlatform.d...

Experience of a first time Sitecore MVP

The Journey I have been working in Sitecore for almost 10 years now. When I was a beginner in Sitecore, I was highly impressed by the incredible community support. In fact, my initial Sitecore learning path was entirely based on community written blogs on Sitecore. During a discussion with my then technology lead Neeraj Gulia , he proposed the idea that I should start giving back to developer community whenever I get chance. Just like I have been helped by many developers via online blogs, stackoverflow etc., I should also try to help others. Fast forward a few years and I met  Nehemiah Jeyakumar  (now an MVP). He had a big archive of his technical notes in the form Sitecore blogs. I realized my first blog dont have to be perfect and it can be as simple as notes to a specific problem for reference in future. That's when I probably created my first blog post on Sitecore. At that time, I didn't knew about the Sitecore MVP program. Over the years, I gained more confidence to writ...

Clean Coding Principles in CSharp

A code shall be easy to read and understand. In this post, I am outlining basic principles  about clean coding after researching through expert recommended books, trainings and based on my experience. A common example to start with is a variable declaration like - int i  The above statement did not clarify the purpose of variable i. However,  the same variable can be declared as -  int pageNumber The moment we declared the variable as int pageNumber, our brain realized that the variable is going to store the value for number of pages. We have set the context in our brain now and it is ready to understand what the code is going to do next with these page numbers. This is one of the basic advantages of clean coding. Reasons for clean coding -  • Reading clean code is easier - Every code is revisited after certain amount of time either by the same or different developer who created it. In both the cases, if the code is unclean, its difficult to understand and u...
