Terms in this definition

• Chat message roles

  Labels on chat messages: instructions go under system, the person's input under user, the model's previous answers under assistant, and results returned by a called tool under tool (or function).

• az aks

  Azure CLI commands for managing AKS. For example, az aks install-cli installs kubectl, while running az aks update or az aks nodepool update with --enable-cluster-autoscaler --min-count --max-count enables autoscaling.

• AKS

  Short for Azure Kubernetes Service, a managed Kubernetes offering that gives full control of clusters and node pools. Scaling uses the cluster autoscaler and Horizontal Pod Autoscaler; user sign-in is not built in.

• LIKE

  Compares strings with a pattern that can contain the % and _ wildcards. Because it only understands character patterns, searching big volumes of text this way is much slower than using full-text search.

• Cluster autoscaler

  Scales an AKS node pool, Windows pools included, by adding or removing VMs as the demand from pods rises and falls.

• Set

  Secret permission in Key Vault for writing secrets; some older material refers to it as Create.

Related terms

• az aks get-credentials

  Fetches AKS cluster credentials and merges them into kubeconfig, letting kubectl connect. With --admin, it instead retrieves the local administrator credential, intended for emergencies.

• kubelogin

  Plug-in that supplies credentials to kubectl by performing the Microsoft Entra sign-in for AKS. Running az aks install-cli installs it.

• Live data

  Real-time portal view in Container insights showing pod metrics, events and container logs, much as kubectl top pods, get events and logs would.
