The new Azure RBAC for Kubernetes Authorization feature will enable us to manage RBAC for Kubernetes resources from Azure. Another options to use User Assigned Identity or manually create Service Principal (strongly not recommended!). Cluster IdentityĪKS needs its own identity to create additional resources like load balancers and managed disks.It is recommend to use System Assigned Identity because the lifetime of it is bind to the lifetime of the AKS cluster and credentials (certificates) are automatically rotated by Azure every 46 days. The Calico network policy supports more features, including support for both Azure CNI and Kubenet network plugins, and it is the default and recommended network policy solution to use. The Network Policy feature in Kubernetes enables you to define rules for ingress and egress traffic between pods in a cluster. Last, Azure CNI is considered first class citizen in AKS because usually all the new features in AKS are at first developed only for CNI. Another reason why to use Azure CNI instead of Kubenet is because Kubenet network plugin is susceptible to ARP spoofing which is a real issue when using Pod Identities. We will use Azure CNI because it is a prerequisite for using Virtual Nodes.
You can deploy AKS cluster using two network plugins out-of-the-box: Kubenet or Azure CNI. AKS Cluster AKS Cluster components Network Plugin However, it is strongly recommended to use a declarative tool for production workloads, such as Terraform or Bicep. We will be using the imperative way of deploying by leveraging the Azure CLI because it is easier to view the actual workflow fully, and it is much easier to learn by going step-by-step. Then, to learn more about the particular features of that baseline deployment, links are provided in the appropriate section.
#EPHEMERAL POOLS SERIES#
The idea of this post series is not to copy/paste what is already well documented out there but to put in place everything you need to build a baseline deployment for AKS, following the best practices. Everything around AKS is pretty well documented in the official documentation. Recognizing vernal pools in provincial policy will ensure they receive the attention and protection they deserve.Building an AKS baseline architecture - Part 1 - Cluster creationīuilding an AKS baseline architecture - Part 2 - Governanceīuilding an AKS baseline architecture - Part 3 - GitOps with Flux2īuilding an AKS baseline architecture - Part 4 - AAD Pod Identity OverviewĪzure Kubernetes Service (AKS) is a managed Kubernetes cluster offering by Microsoft. If we don’t know where these critical habitats are, we can’t protect them and so we will continue to lose them. Incentive to conserve: There’s a lot we don’t know about vernal pools in Ontario, such as where they are. Vernal pool, Waterloo Regional Forest © Noah ColeĤ. At the same time, they are very vulnerable to major shifts in temperature, precipitation and hydrological regimes. Climate change: Like other wetlands, vernal pools can help buffer against the adverse impacts of climate change. We should raise a glass of fresh water to vernal pools! Vernal pool, Altberg Nature Reserve © Noah Coleģ. Whether we realize it or not, we all benefit from vernal pools. Clean drinking water: Vernal pools are an important element of our headwaters and help to regulate water flow and keep our rivers and streams healthy. Thus acting as predator-free nurseries!

Because they dry out in the summer, vernal pools don’t support fish which might otherwise eat the eggs or young of these species. Habitat: Vernal pools are wetlands, and like all wetlands they provide critical habitat for many species, including wood frogs, Jefferson salamanders and fairy shrimp.
