For the deployment we will use an AKS cluster with the IoT Edge virtual Read more [...]

Configuring Azure Kubernetes Service via the Terraform OSS Azure Resource Provider to use a custom DNS server for domain specific name resolution

I have already written about on how to use a custom DNS server for domain specific name resolution with AKS a couple of weeks ago. -> https://www.danielstechblog.io/using-custom-dns-server-for-domain-specific-name-resolution-with-azure-kubernetes-service/ Today I am writing about how you can leverage the newly announced Terraform OSS Azure Resource Provider for the same configuration with Read more [...]

Building ARM-based container images with VSTS for your Azure IoT Edge deployments

Currently, I am working and playing around with Azure IoT Edge deployments in combination with Azure Kubernetes Service and a Raspberry Pi 2. The files referenced in through out the blog article can be found in my GitHub repository. -> https://github.com/neumanndaniel/kubernetes/tree/master/iotedge/webserver My first challenge was to find a way on how to build ARM-based container images Read more [...]

Azure Kubernetes Service and Azure Active Directory integration

Last week Microsoft announced the GA of Azure Kubernetes Service. Since then we can integrate Azure Active Directory with Azure Kubernetes Service. When enabling Azure Active Directory integration, AKS requires that RBAC is also enabled. A detailed configuration guide can be found in the Azure documentation. -> https://docs.microsoft.com/en-us/azure/aks/aad-integration Before you can make Read more [...]

Using custom DNS server for domain specific name resolution with Azure Kubernetes Service

Just a short blog post about a small challenge I had these days. If you want to specify a custom DNS server for domain specific name resolution with AKS, you can do so.

Using ACS Engine to build private Kubernetes clusters with bring your own Virtual Network on Azure

Looking at Azure Container Service (AKS) – Managed Kubernetes you may have recognized that AKS currently does not support bring your own VNET and private Kubernetes masters. If you need both capabilities and one of them today, you must use ACS Engine to create the necessary Azure Resource Manager templates for the Kubernetes cluster deployment. -> https://github.com/Azure/acs-engine Beside Read more [...]

Keeping your ACS Engine Kubernetes cluster on Azure up-to-date

It is quite simple to keep a Kubernetes cluster created by ACS Engine on Azure up-to-date, because the master and agent nodes are configured by default to automatically apply security patches on a nightly schedule. But you need a solution like Kured to automatically reboot the agent nodes in the cluster, so the security patches take effect. Rebooting the master nodes is a manual task after all. -> Read more [...]
