Taints and Tolerations in Kubernetes

Taints are applied to Node’s and Tolerations are applied to Pod’s.

They restrict Pod’s to be allocated to Node’s

Check if any taints are already applied to node

kubectl describe controlplane | grep Taints

Apply taint to a node

//kubectl taint nodes <<node name>> <<key>>=<<value>>:<<effect>>
kubectl taint nodes controlplane app=webapp:NoSchedule

Taint types/effects:-

  • NoSchedule – The pod will not get scheduled to the node without a matching toleration.
  • PreferNoSchedule  – This is a softer version of NoSchedule where the controller will not try to schedule a pod with the tainted node. However, it is not a strict requirement
  • NoExecute – This will immediately evict all the pods without the matching toleration from the node

Add toleration to Pod-

// nginx-pod.yaml
apiVersion: v1
kind: Pod
metadata:
  name: nginx-app
spec:
  containers:
  - name: nginx
    image: nginx
  tolerations:
  - key: color
    value: blue
    operator: Equal
    effect: NoSchedule

Tolerations Operators-

  • Equal – default value. Checks the value of key with the node taint key and value
  • Exists – checks if the key ecists in the node taint key

Create a new Pod

kubectl create -f nginx-pod.yaml

Check the POD created on which node-

kubectl get pods -o wide

Untaint the node (note “-” after NoSchedule)

kubectl taint nodes controlplane node-role.kubernetes.io/master: NoSchedule-

Sitecore Asp.Net rendering with Content Resolver for Helix Examples Solution

In my previous post we saw how to create a simple rendering with data source.

For creating rendering using content resolver first follow the blog <<enter blog url here>>

Content resolvers help provice more complex data beyond the serialization of a component data source.

In this blog will list all the Articles on the page which are marked as Featured Article.

The custom logic for filtering will go in Content resolver.

Craete a project for Content Resolver(.net framework 4.8) . This framework is used just to follow with the exisitng content resolvers provided by Helix Examples Solution.

Content Resolver Project (BasicCompany.Feature.Articles.Platform)

Create a new .Net Framework project

Instead of creating new poroject I will copy the project from Navigation/Platform folder and rename it to BasicCompany.Feature.Articles.Platform.

Delete all the files from this project as it relates to Navigation. You may also want to change the AssemblyName and the AssemblyInfo file.

Create Models for Articles and Article

Create Models Folder and add below models

Articles.cs

using Sitecore.Data.Items;
using System.Collections.Generic;

namespace BasicCompany.Feature.Articles.Models
{
    public class Articles
    {
        public Item ArticlesPage { get; set; }

        public IList<Article> ArticleItems { get; set; }
    }
}

Article.cs

using Sitecore.Data.Items;

namespace BasicCompany.Feature.Articles.Models
{
    public class Article
    {
        public Item Item { get; set; }

        public Item ItemData { get; set; }
        public string Url { get; set; }
    }
}

Create Service for ArticleBuilder and ArticleRootResolver

Create a new folder Services and following-

//IArticleBuilder
 public interface IArticleBuilder
    {
        Articles.Models.Articles GetArticles(Item contextItem);
    }
//ArticleBuilder 

 public class ArticleBuilder : IArticleBuilder
    {
        private readonly IArticleRootResolver _articleRootResolver;
        private readonly BaseLinkManager _linkManager;

        public ArticleBuilder(BaseLinkManager linkManager, IArticleRootResolver articleRootResolver)
        {
            _articleRootResolver = articleRootResolver;
            _linkManager = linkManager;
        }

        public Articles.Models.Articles GetArticles(Item contextItem)
        {
            var articleRoot = _articleRootResolver.GetArticleRoot(contextItem);
            if (articleRoot == null)
            {
                return new Articles.Models.Articles();
            }

            return new Articles.Models.Articles()
            {
                ArticlesPage = articleRoot,
                ArticleItems = GetArticleItems(articleRoot, contextItem)
            };
        }

        private IList<Article> GetArticleItems(Item articleRoot, Item contextItem)
        {
            var items = new List<Item>();

            items.AddRange(articleRoot.Children.Where(item => item.DescendsFrom(Templates.ArticleItem.Id)));

            var articleItems = items.Select(item => new Article()
            {
                Item = item,
                ItemData = item.Axes.GetDescendants().FirstOrDefault(itemData => itemData.DescendsFrom(Templates.ArticleItemData.Id)),
                Url = _linkManager.GetItemUrl(item)
            }).ToList();

            return articleItems;
        }
    }
//IArticleRootResolver

 public interface IArticleRootResolver
    {
        Item GetArticleRoot(Item contextItem);
    }

namespace BasicCompany.Feature.Articles.Services
{
    public class ArticleRootResolver : IArticleRootResolver
    {
        public Item GetArticleRoot(Item contextItem)
        {
            if (contextItem == null)
            {
                return null;
            }
            return contextItem.DescendsFrom(Templates.ArticleRoot.Id)
                ? contextItem
                : contextItem.Axes.GetAncestors().LastOrDefault(x => x.DescendsFrom(Templates.ArticleRoot.Id));
        }
    }
}

Create Layout Service i.e. content resolver class

Create new folder LayoutServices and add following-

namespace BasicCompany.Feature.Articles.LayoutService
{
    public class ArticleContentResolver : Sitecore.LayoutService.ItemRendering.ContentsResolvers.RenderingContentsResolver
    {
        private readonly IArticleBuilder _articleBuilder;

        public ArticleContentResolver(IArticleBuilder articleBuilder)
        {
            _articleBuilder = articleBuilder;
        }

        public override object ResolveContents(Rendering rendering, IRenderingConfiguration renderingConfig)
        {
            var articles = _articleBuilder.GetArticles(this.GetContextItem(rendering, renderingConfig));

            var contents = new
            {
                ArticleItems = articles.ArticleItems.Select(item => new
                {
                    Item = item.Item,
                    ItemData = item.ItemData,
                    Serialized = base.ProcessItem(item.ItemData, rendering, renderingConfig)
                }).Select(article => new
                {
                    Url = LinkManager.GetItemUrl(article.Item),
                    Id = article.Item.ID,
                    Fields = new
                    {
                        Title = article.Serialized[article.ItemData.Fields["Title"].Name],
                        Description = article.Serialized[article.ItemData.Fields["Description"].Name],
                        ShortDescription = article.Serialized[article.ItemData.Fields["ShortDescription"].Name],
                    }
                })
            };

            return contents;
        }
    }
}

Create Service Configurator to register the services-

namespace BasicCompany.Feature.Articles
{
    public class ServicesConfigurator : IServicesConfigurator
    {
        public void Configure(IServiceCollection serviceCollection)
        {
            serviceCollection.AddTransient<Services.IArticleBuilder, Services.ArticleBuilder>();
            serviceCollection.AddTransient<Services.IArticleRootResolver, Services.ArticleRootResolver>();
        }
    }
}

Create Template Class

Change the Item ID’s as per your Sitecore Instance

namespace BasicCompany.Feature.Articles
{
  public static class Templates
  {
        public static class ArticleItem
        {
            public static readonly ID Id = new ID("{EE5CE126-890D-4F01-9DD5-3D81FC397A91}"); //
        }

        public static class ArticleItemData
        {
            public static readonly ID Id = new ID("{8AA19CA1-99A6-4588-B1D7-3FA9A8F6756A}"); //
        }

        public static class ArticleRoot
        {
            public static readonly ID Id = new ID("{A46A11C6-C7F9-4F61-BF0C-FFF060F0FECC}"); //
        }
  }
}

Create App Config to register the ServiceConfigurator-

Create Feature.Articles.config file in App_Config/Include/Feature folder

<?xml version="1.0"?>

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <services>
      <configurator type="BasicCompany.Feature.Navigation.ServicesConfigurator, BasicCompany.Feature.Navigation" />
    </services>
  </sitecore>
</configuration>

Create Templates for Article

These templates are used to indicate the different level s of Article. i..e Article Page- will inherit from _ArticleRoot, ArticlePage will inherit from _ArticleItem and Article Content will inherit from _ArticleItemData

Sitecore Items

Create Rendering Content Resolver

Create a New “Rendering Contents Resolvers Folder” in /sitecore/system/Modules/Layout Service

Craete a New “Rendering Contents Resolver” in this folder.

Provide the type – BasicCompany.Feature.Articles.LayoutService.ArticleContentResolver, BasicCompany.Feature.Articles

Create Articles Json Rendering

Craete a neJson rendering name “Articles” and newly created content resolver in the “Rendering Contents Resolver” field.

Add the new rendering to the page

Publish items

Rendering Project

Create Models Articles.cs

using Sitecore.AspNet.RenderingEngine.Binding.Attributes;
using Sitecore.LayoutService.Client.Response.Model.Fields;

namespace BasicCompany.Feature.Articles.Models
{
    public class Articles
    {
        [SitecoreComponentField]
        public ContentListField<Article> ArticleItems { get; set; }
    }
}

Create new view Articles.cshtml in /Views/Shared/Components/SitecoreComponent

@using Sitecore.AspNet.RenderingEngine.Extensions
@model BasicCompany.Feature.Articles.Models.Articles


<div class="container">
    <div class="product-list-columns columns is-multiline">
        @foreach (var article in Model.ArticleItems)
        {
            <partial name="_ArticleList" model="article" />
        }
    </div>
</div>

Create _ArticleList.cshtml in Views/Shared folder

Note its using ItemLinkField

@model ItemLinkField<Article>

<a href="@Model.Url" class="column product-list-column is-4-desktop is-6-tablet">
    <div class="card">
        <div class="card-content">
            <div class="content">
                <h4 asp-for="@Model.Fields.Title"></h4>
                <p asp-for="@Model.Fields.ShortDescription"></p>
            </div>
        </div>
    </div>
</a>

Update the RenderingEngineOptionsExtensions

namespace BasicCompany.Feature.Articles.Extensions
{
    public  static class RenderingEngineOptionsExtensions
    {
        public static RenderingEngineOptions AddFeatureArticle(this RenderingEngineOptions options)
        {
            options

                .AddModelBoundView<Article>("Article")
                .AddModelBoundView<Models.Articles>("Articles");
            return options;
        }
    }
}

Update Articles.modules.json to serialiaze content resolver

{
  "namespace": "Feature.Articles",
  "items": {
    "includes": [
      {
        "name": "templates",
        "path": "/sitecore/templates/Feature/Articles"
      },
      {
        "name": "renderings",
        "path": "/sitecore/layout/Renderings/Feature/Articles"
      },
      {
        "name": "contents-resolvers",
        "path": "/sitecore/system/Modules/Layout Service/Rendering Contents Resolvers/Articles"
      }
    ]
  }
}

IMP – Ensure the Startup.cs has AddFeatureArticle() added in AddSitecoreRenderingEngine

Output

List of Articles-

When we click on any of the Article take to the Article page-

The above pages are shown as per this structure in Sitecore

Configure Sitecore Content Serialization for ASP.Net Rendering with Helix Examples Solution

In this blog will creata a new component name Article in the Helix Examples Solution to demonstrate how to configure and use Sitecore Content Serlialization (SCS).

Assuming the Sitecore CLI is installed along with Sitecore.DevEx.Extensibility.SerializationSitecore.DevEx.Extensibility.Publishing plugins are installed.

For more details on the plugin installation please see this link- https://doc.sitecore.com/xp/en/developers/101/developer-tools/install-sitecore-command-line-interface.html

Open the helix-basic-aspnetcore folder in Visual Studio and see Sitecore.json file. This file has the configuration settings for SCS.

modules – willl look into the src folder for *.module.json file for any component specific configuration the items that need to be serialized.

So lets create a new module or rendering feature named “Articles”. Just a folder and not a project itself

1. Create a module json for serlialization configuration

IMP – Create Articles.module.json file in the project root folder

Add following to the json file-

{
  "namespace": "Feature.Articles",
  "items": {
    "includes": [
      {
        "name": "templates",
        "path": "/sitecore/templates/Feature/Articles"
      },
      {
        "name": "renderings",
        "path": "/sitecore/layout/Renderings/Feature/Articles"
      }
    ]
  }
}

Here the items that will be serliazed are templates and rendering from the given path in Sitecore to the local Solution Folder configured in Sitecore.json file the path mentioned in defaultModuleRelativeSerializationPath property. See step 1

IMP- Ensure the module file is in Articles folder. Your project folder should looks like this-

2. Create a Sitecore Template and Rendering for Articles

Create a Json Rendering for now(fill in the details later)

3. Sync the items (manual)

Execute following command to serlaize the items for Articles-

dotnet sitecore ser pull

Project folder should now have items folder with templates and rendering-

Thats it any Templates and rendering created for Articles (new component) should be serliazed.

Refer BasicCompany.module.json for any placeholders, layouts etc serlization at the project level.

Hope this helps.

Kubernetes commands for managing Pods

To get the cluster info use-

kubectl cluster-info

To get list of nodes user-

kubectl get nodes

Creating Pod – imperative way

Create a POD with nginx image and name nginx in default namespace

// kubectl run <<pod name>> --image <<image in docker hub>> 
kubectl run nginx --image nginx

Create a POD with nginx image and name nginx in different namespace

// kubectl run <<pod name>> --image <<image in docker hub>> -n <<namespace name>>
kubectl run nginx --image nginx -n production

Get Pods and details

Get a list of POD’s in default namespace

kubectl get pods

Get a list of POD’s in other namespace

//kubectl get pods -n <<namespace name>>
kubectl get pods -n production

Check the node of the Pod it is created-

kubectl get pods -o wide

Create POD using yaml – declarative way

// file name- pod-definition.yaml
apiVersion: v1
kind: Pod
metadata:
  name: nginx-pod-yaml
spec:
  containers:
    - name: nginx-container-yaml
      image: nginx

Create a pod declarative way-

kubectl create -f pod-definition.yaml

Deleting Pod

Delete a pod in default namespace

// kubectl delete pod <<pod-name>>
kubectl delete pod nginx-pod-yaml

Delete all pods in default namespace

kubectl delete --all pods

Delete a pod in custom namespace

//kubectl delete pod <<pod-name>> -n <<namespace-name>>
kubectl delete pod nginx-pod-yaml -n development

Delete all pods in custom namespace

//kubectl delete --all pods -n <<namespace-name>>
kubectl delete --all pods -n development

Create a Asp.Net simple rendering using data source in Helix Examples Solution

In this blog will create a simple rendering uing Asp.Net Rendering SDK in Helix Examples Solution

Please refer the blog to create a rendering folder and configure the SCS before proceeding this blog.

So lets create a new module or rendering feature named “Articles”.

1. Create a Feature project using Razor Class Library

Project Name – BasicCompany.Feature.Articles.Rendering

Notice the project path

Choose .Net Core 3.1 Framework-

Delete any exisitng files and folders under this project-

Edit the project to use netcoreapp3.1 and AddRazorSupportForMvc to true

Rename helix-basic-aspnetcore\src\Feature\Articles\BasicCompany.Feature.Articles.Rendering to rendering. Just to follow other feature fodler structure.

2. Install Sitecore packages

Sitecore.AspNet.RenderingEngine

Sitecore.LayoutService.Client

I have installed verions 16 just to be in sync with other projects. You may install the latest.

New rendering project should have these packages installed-

Remove these packages as this may be not required at thi point of time or downgrade this to 3.1.1

Refer the new created rendering project to BasicCompany.Project.BasicCompany.Rendering

When the solution is build you may see this error-

Severity Code Description Project File Line Suppression State
Error The package reference ‘Sitecore.AspNet.RenderingEngine’ should not specify a version. Please specify the version in ‘C:\projects\Helix.Examples\examples\helix-basic-aspnetcore\Packages.props’ or set VersionOverride to override the centrally defined version. BasicCompany.Feature.Articles.Rendering C:\projects\Helix.Examples\examples\helix-basic-aspnetcore\src\Feature\Articles\rendering\BasicCompany.Feature.Articles.Rendering.csproj

Solution– Remove the version for the plugin fropm project file

Edit the project file and remove version from the PackageReference-

Solution should build successully.

3. Ensure Articles.modules.json file in Feature folder

Please see this blog <<Enter blog url here>> how to create a module.json file to serliaze the Sitecore items for new Feature.

4. Create required Sitecore Templates, content, renderings and Placeholder Settings

Template – Article in following path- /sitecore/templates/Feature/Articles

Page Type Template – Create 2 page type templates “Articles” and “Article” page as below.

Add any required Insert Options where necessary.

IMP- inherit from _NavigationItem to display the Articles as Navigation option

Enter Navigation Title for Articles page-

Content

Create content in Home page based on the Article templates created.

Rendering

Create a new Json Rendering Article. See previous post

Set Datasource Location- ./Page Components|query:./ancestor-or-self::*[@@templatename=’Site’]/Shared Content/Articles

Datasource Template- /sitecore/templates/Feature/Articles/Article

Add rendering to Template

Add Header, Article and Footer Controls to the Presentation

Select appropriate datasource for the Article component-

You can also add the component from experience editor. For simplicity purpose I am adding this from the presentation details manually.

Publish the changes and see https://www.basic-company-aspnetcore.localhost

Note:- If you get bad gateway error the resolution is in this blog <<blog for resolution>>

you should see the Articles option in Navigation-

Note- We wont be configuring “Articles” page in this blog. Will see that in next blog when uing Content Resolver.

See thie Article page-

https://www.basic-company-aspnetcore.localhost/Articles/Sitecore%20Content%20Serialization%20structural%20overview

There is a error – “Unknown component ‘Article'”. This is because we havent yet created view for this component.

Create Model in BasicCompany.Feature.Articles.Rendering project for rendering Article component

Note the propeties are using Sitecore.LayoutService.Client.Response.Model.Fields

using Sitecore.LayoutService.Client.Response.Model.Fields;
using System;
using System.Collections.Generic;
using System.Text;

namespace BasicCompany.Feature.Articles.Rendering.Models
{
    public class Article
    {
        public TextField Title { get; set; }

        public RichTextField Description { get; set; }

        public TextField ShortDescription { get; set; }
    }
}

Create View in BasicCompany.Feature.Articles.Rendering project for rendering Article component

Create Article.cshtml file under Views/Shared/Components/SitecoreComponent

Add following markup-


@model Article

<div class="container">
    <section class="hero is-small product-detail-hero">
        <div class="hero-body">
             <h3  class="title" asp-for="Title"></h3>
            <sc-text class="subtitle is-one-quarter" asp-for="Description"></sc-text>
        </div>
    </section>
</div>

InViews Folder create _ViewImports.cshtml file and put the following in file-

@using Sitecore.LayoutService.Client.Response.Model
@using Sitecore.LayoutService.Client.Response.Model.Fields
@using Sitecore.AspNet.RenderingEngine.Extensions
@using BasicCompany.Feature.Articles.Rendering.Models

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@addTagHelper *, Sitecore.AspNet.RenderingEngine

Add Extensions for registering the ModelBoundView. This is a static class and will be used in Project Rendering on application startup (BasicCompany.Project.BasicCompany.Rendering).

using BasicCompany.Feature.Articles.Rendering.Models;
using Sitecore.AspNet.RenderingEngine.Configuration;
using Sitecore.AspNet.RenderingEngine.Extensions;

namespace BasicCompany.Feature.Articles.Extensions
{
    public  static class RenderingEngineOptionsExtensions
    {
        public static RenderingEngineOptions AddFeatureArticle(this RenderingEngineOptions options)
        {
            options
                .AddModelBoundView<Article>("Article");            
            return options;
        }
    }
}

In BasicCompany.Project.BasicCompany.Rendering project, Startup.cs register the component-

Build the Project

Output– https://www.basic-company-aspnetcore.localhost/Articles/Sitecore%20Content%20Serialization%20structural%20overview

Issues

Bad gateway error while accessing – https://www.basic-company-aspnetcore.localhost/

Solution-

Restart the rendering container

docker ps
docker restart <<rebdering container>>

Debug Helix Examples solution using Asp.Net Rendering hosted in Docker Containers

See this blog to setup the development environment for Helix Examlpes using Docker

Open the solution from following location – \examples\helix-basic-aspnetcore

Open the containers tab and should list all the containsers with its status-

You may also use following command to check the status of contrianers-

docker ps

Lets debug the Navigation which has content resolver-

Right click the CD container and Attach to Process

Select Managed(.Net 4.x) debug type. Select w3wp.exe and click Attach.

Helix Examples Solution should now run in debug mode.

Build the solution, add a breakpoint to any of the resolvers (Header or Footer)

Refresh or visit the site – https://www.basic-company-aspnetcore.localhost/ and should be able to see the debugger-

Issues debuging or just building the solution-

Bad Gateway-

Solution- You may see the errors with command-

docker-compose logs -f rendering

Following log appears- binary is being used by another process. This is the issues with the dotnet watch with the docker

Solution- Restart the rendering container

This should bring up the site.

You can also watch the changes outside the docker. See here for more details-

Sitecore Headless Development with ASP.NET Rendering SDK – Helix Examples Solution – The Docker Way

This blog will give a quick overview of setting development environment for Headless Development with ASP.Net Rendering SDK using the Helix Examples and the docker.

Although there are videos and blogs around same I will do a quick walk through on setting Helix Examples and any errors I faced whilst setting up the environment.

Refer the following for same – https://github.com/Sitecore/Helix.Examples/tree/master/examples/helix-basic-aspnetcore

Install .Net Core 3.1

https://dotnet.microsoft.com/en-us/download/dotnet/3.1

Install .Net core 3.1 on your machine and this is required to create any rendering or platform projects later to extend the Helix Examples Solution or compiling the existing code.

Install Docker Desktop on Windows

https://docs.docker.com/desktop/windows/install/

Run this on Hyper-V mode and Switch to Windows Containers

Install Visual Studio Code and Visual Studio 2022 Community Edition

https://visualstudio.microsoft.com/vs/community/

https://code.visualstudio.com/download

Whilst installing Visual Studio 2022 select the .Net Framework project and templates option as the platform projects uses .Net Framework 4.8 version. This will also help further if you want to extend the solution.

Install and Configure Windows Terminal (optional)

https://docs.microsoft.com/en-us/windows/terminal/install

https://dev.to/shahinalam02/customize-your-terminal-using-oh-my-posh-theme-38if

https://www.hanselman.com/blog/my-ultimate-powershell-prompt-with-oh-my-posh-and-the-windows-terminal

Install Windows Terminal, refer above link and if you fancy applying the themes, although this is optional.

Install git

https://git-scm.com/download/win

Clone Helix Examples Solution

https://github.com/Sitecore/Helix.Examples

https://github.com/Sitecore/Helix.Examples.git

Initialise the config

Navigate to \examples\helix-basic-aspnetcore and run following-

.\init.ps1 -LicenseXmlPath C:\<<path to license>>\license.xml -SitecoreAdminPassword "b"

This should initalise teh .env file and fill in the values of the variables for License and Admin Password. Also it will populate other variables.

Build Images

Once the config are initialised run folowing command-

up.ps1

Once all the images are downloaded and built along with solution login to CM should will be asked.

Login to the CM and Allow access to Sitecore API and Offline Access

Once this done the CD and CM app should be ready along with the data been synched.

Check the logs for any errors in rendering with following command-

Solidity deployment error – ContractNotFound: No contract deployed at address

At time when the Ganache tool is re-opened all the Transactions and Constracts are reset. Whilst deploying contract you might see the error –

ContractNotFound: No contract deployed at {address}

PS C:\Projects\Blockchain\Solidity\brownie_fundme> brownie run .\scripts\deploy.py --network ganache-local

ContractNotFound: No contract deployed at 0x7465E5ca8aFeFba39eFD83bd056ACAafa3d16646

Solution-

Delete all the files and folders in Deployment folder as closing the Ganache tool will reset contracts etc. the deployment folder has references to old contract.

Add new network in Ganache using brownie for Ethereum Smart Contract local development

This should show the list of networks available in Brownie.

brownie networks list

In the Ethereum (persistent network) there is no Ganache(local) network

Add a network to Ethereum

brownie networks add Ethereum ganache-local host=http://127.0.0.1:7545 chainid=1337

Name of the network- ganache-local

host- where ganache endpoint is listening i.e. RPC Server

chainid – for ganache it is 1337

Output
