Since Rancher v2.7.X, RKE2 has become the default Kubernetes version for provisioning on all major hyper scalers and virtualization platforms. Let’s look at enabling a cloud provider using Terraform. Terraform Plan I’m assuming that you have set up Terraform already. For the actual RKE2 cluster, we will be using the rancher2_cluster_v2 resource: …

The acronym stands for Telegraf, InfluxDB, Chronograf, and Kapacitor; InfluxDB 2.0 is more of a TI stack though since InfluxDB now bundles the UI. Here is a manual installation of the complete…

SUSE Rancher includes an operator-based Prometheus installation in the Apps Marketplace. For long-term storage, it can be beneficial to use a central instance for logging and monitoring, such as the Grafana Cloud. We will use Grafana Labs’ Cloud offering in this example, but you could use a self-hosted Mimir instance…

The “other” observability tool for Rancher and Kubernetes is Elasticsearch. Here is a manual installation of the complete stack; as in the previous article on Prometheus, this installation neither provides high availability nor persistence. All configuration files below have been copied and adapted from the respective Github repositories and follow…

Even though Rancher offers a cluster driver for Azure AKS, it can sometimes be helpful to create and import an AKS cluster, as it provides complete flexibility when defining the cluster. In this article, we’ll use Terraform to create and import an AKS cluster into Rancher using the generic cluster…

Even though SUSE Rancher includes an operator-based Prometheus installation in the Apps Marketplace, it can be beneficial to manually install a complete Prometheus/Loki/Grafana stack. All configuration files below have been copied and adapted from the respective Github repositories and follow their published licenses. State Metrics An essential tool for Kubernetes metrics is…

Even though Rancher offers node and cluster drivers for most cloud providers and hypervisors, it can sometimes be helpful to import existing clusters and register them. In this article, we’ll be using Terraform to register a cluster with Rancher. …
