Performing Terraform Import via Azure Pipelines for Existing Azure Resources

Importing state to terraform may be required when a resource is manually created previously, now need to be managed by terraform. Or it can be a situation where you Move code from one repo to another for reorganizing purpose and now you need to refer to exesting resource in Azure and map it to new repo terraform code. The state import can be performed with terraform import command manually. However, performin such task manually targeting production environments is not ideal and kind of impossible, in autmated deployment implementations. In this post let's discuss, a Azure pipeline task that can be used to perform the state imports in a rerunnable way.

Such task toupdate terraform state in Azure pipline should be placed between the terraform init and terraform plan tasks as shown below.

Enable Prometheus Data Scraping for Bitnami Redis Cluster Deployed on AKS with Managed Prometheus

 "Setup Redis Cluster with JSON and Search Modules on AKS with Binami Redis Using Custom Image" and "Setup Managed Prometheus for AKS via Terraform" are explained in the previous posts. To enable setting up monitoring and alerting for the Redis Custer deployed in AKS the first step is to enable Prometheus data scraping in the Redis cluster we deployed on AKS. Let's look at the steps in this post.

The expectation is to have redis metrices available to Azure managed grafana via the managed prometheus in AKS as shown below.

Setup Managed Prometheus for AKS via Terraform

 We have discussed "Deploying Azure Managed Grafana with Terraform" ealier. Now that we have managed grafana available in Azure for the AKS clsuters we can enable managed prometheus. You can setup prometheus on your own in AKS however it is beter to use Azure managed prometheus with AKS as it would leverage the capabilities of Azure monitor and Azure managed grafana to better monitoring and alerting abilities and avoid additional work required to setup full monitoring and observability on your own in an AKS cluster. The offcial documentation is here for leaning more information on the setup.

Setup Redis Standalone with JSON and Search Modules on AKS with Binami Redis Using Custom Image to Allow Local Development

 As we discusssed in  "Setup Redis Cluster with JSON and Search Modules on AKS with Binami Redis Using Custom Image" the cluster deployemnt does not allow the redis to be accessed outside of AKS/kubernetes. To allow local development with redis we have to deploy redis standalone on AKS. Ideally the standalone should be setup in development environment and clsuter mode should be setup in QA and production environments. Let's look at how to setup redis standalone with json and search modules using custom image we built in "Build Custom Docker Images with Redis Json and Search Module Support for deploying Bitnami Redis Cluster and Standalone in AKS".
