Run a Test on RabbitMQ Cluster in AKS with perf-test

 Once a RabbitMQ cluster is deployed on AKS as described in "Setting Up RabbitMQ Cluster in AKS Using RabbitMQ Cluster Operator" it would be grat to test if the deployment is working as expected. For this purpose we can use a perf-test . Let's run a perf-test step by step for RabbitMQ in AKS cluster using wsl in this post.

Expectation is to run a performance test as shown below.

Resolve "System.NotSupportedException: Globalization Invariant Mode is not supported" in Microsoft.Data.SqlClient with Alpine Docker Image

 You may encounter exception "System.NotSupportedException: Globalization Invariant Mode is not supported" in Microsoft.Data.SqlClient in Linux Alpine docker images. Exception details are as below.

fail: Poc.Common.Api.Middleware.GlobalExceptionHandlerMiddleware[0]      Unexpected error occurred.      System.NotSupportedException: Globalization Invariant Mode is not supported.         at Microsoft.Data.SqlClient.SqlConnection.TryOpen(TaskCompletionSource`1 retry, SqlConnectionOverrides overrides)         at Microsoft.Data.SqlClient.SqlConnection.Open(SqlConnectionOverrides overrides)         at Microsoft.Data.SqlClient.SqlConnection.Open()         at Poc.Domain.Core.Implementation.Sql.SqlCommanRunner.RunAsync(String command) in /build/src/Shared/Domain/Poc.Domain.Core/Implementation/Sql/SqlCommanRunner.cs:line 20

Setting Up RabbitMQ Cluster in AKS Using RabbitMQ Cluster Operator

 We have discused "Setting Up RabbitMQ Cluster Operator and Topology Operator via Azure Pipelines in AKS" in the previous post. The deployed cluster oprator in AKS can be used deploy a RabbitMQ cluster. In this post let's explore deploying a production ready RabbitMQ Cluster in AKS (without TLS/SSL - we will explore that in a future post), to be used with apps deployed in same AKS cluster. 

Once successfully deployed the RabbitMQ clsuter the rabbitmq namcspace should have resources shown in the below image. We are deploying a three node RabbitMQ cluster, each pod scheduled in a different Azure availability zone node. Cluster access setup with service/rabbitmq-cluster ClusterIP, as we only need access within AKS cluster for apps. How to use it for local development, we can discuss in a future post.

Setting Up RabbitMQ Cluster Operator and Topology Operator via Azure Pipelines in AKS

Using operators to setup RabbitMQ cluster in  AKS (kubernetes) is a recomended approach. There are two RabbitMQ operators we need to deploy into AKS for setting up a RabbitMQ cluster and managing message setup in the deployed RabbitMQ cluster.

• Cluster Operator: Automate provisioning, management and oprations of a RabbitMQ cluster within AKS.
• Messaging Topology Operator: Managing message topologies within the deployed RabbitMQ cluster in AKS.

In this post let's look at how to seup above two operators in AKS using Azure DevOps pipeline step.
