Using Azure Policy for Kubernetes

In my last blog post I mentioned that the next topic is about Azure Policy in combination with Azure Arc enabled Kubernetes. I decided to write about Azure Policy for Kubernetes instead covering Azure Kubernetes Service and Azure Arc enabled Kubernetes. As Azure Policy for Kubernetes is based on the Open Policy Agent Gatekeeper implementation, I will also highlight the difference between the Read more [...]

Using Azure Resource Graph to show ASC container image scan findings

In my previous blog post I showed you how to connect your Azure Container Registries with Azure Security Center. -> https://www.danielstechblog.io/connecting-azure-container-registry-with-azure-security-center/ Today we talk about how to receive the scan results via Azure Resource Graph instead of using the Security Center UI path. You can submit your queries against the Resource Graph Read more [...]

Connecting Azure Container Registry with Azure Security Center

Back in March Microsoft released the container image scanning solution in the Azure Security Center for the Azure Container Registry. -> https://azure.microsoft.com/en-us/updates/vulnerability-scanning-for-images-in-azure-container-registry-is-now-generally-available/ The container image scanning solution is powered by Qualys and seamlessly integrated into the Security Center UI. Connecting Read more [...]

Secure Kubernetes API server access in Azure Kubernetes Service

Running Kubernetes at a cloud provider especially managed Kubernetes like AKS or GKE provides you with a solid foundation and applied security best practices for the managed master control plane. But there is one downside, the public accessible API endpoint to control the Kubernetes cluster. Even the API endpoint is only exposed via HTTPS and access is secured via the Azure Active Directory integration Read more [...]

Disable the Kubernetes dashboard on Azure Kubernetes Service

A recently introduced change enables the capability to disable the Kubernetes dashboard on an AKS cluster. This is achieved by providing the Kubernetes dashboard as an AKS add-on like the Azure Monitor for containers integration, AKS virtual nodes or the HTTP application routing. I stumbled over that capability in the Terraform Azure provider documentation for Azure Kubernetes Service. -> Read more [...]

AKS VMSS base image update script – multiple node pool support

At the beginning of September, I have published a blog post about how to update the base image of a VMSS-based AKS cluster. -> https://www.danielstechblog.io/updating-the-base-image-of-a-vmss-based-aks-cluster/ On LinkedIn I had a good discussion with one of the AKS PMs about that and I want to highlight two things first. The shell script I have written directly interacts with the VMSS Read more [...]

Secure Jenkins worker nodes on Azure

Jenkins has two nifty plugins available to leverage the power of the Azure platform for on-demand worker nodes. -> Azure Container Instances -> Azure Virtual Machines In this blog post I want to quickly highlight to secure the access to Jenkins worker nodes running on Azure. The assumption is that your Jenkins CI master is running outside of Azure e.g. on-premises. When you are using Read more [...]

Updating the base image of a VMSS-based AKS cluster

Earlier this year I had written a blog post about updating the VMSS base image of an aks-engine cluster. -> https://www.danielstechblog.io/updating-the-base-image-of-an-vmss-aks-engine-cluster/ Today, we focus on Azure Kubernetes Service running with VMSS. Microsoft releases updates regularly to the AKS service and refreshes also the base image for the AKS worker nodes. -> https://github.com/azure/aks/releases This Read more [...]

Distribute Azure Kubernetes Service kubeconfig credentials

Last week I showed you the kubeconfig credentials distribution for AKS Engine. -> https://www.danielstechblog.io/distribute-aks-engine-kubeconfig-credentials/ In this blog post I walk you through the steps for Azure Kubernetes Service. The distribution of the kubeconfig credentials for an AKS cluster with AAD integration is a lot easier thanks to the following two built-in RBAC roles. -> Read more [...]

Distribute AKS Engine kubeconfig credentials

In my last blog post I showed you the integration of an AKS Engine cluster with Azure Active Directory. -> https://www.danielstechblog.io/using-an-aks-engine-cluster-with-azure-active-directory-integration/ Today we talk about the distribution of the kubeconfig credentials to our engineers and developers. You do not want to give them access via SSH to the AKS Engine master for two reasons. Read more [...]
