This page shows how to use kubectl port-forward to connect to a MongoDB server running in a Kubernetes cluster. This type of connection can be useful for database debugging. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts.

Production-Grade Container Orchestration

Objectives Learn about a Service in Kubernetes. Understand how labels and selectors relate to a Service. Expose an application outside a Kubernetes cluster. Overview of Kubernetes Services Kubernetes Pods are mortal. Pods have a lifecycle. When a worker node dies, the Pods running on the Node are also lost. A Replicaset might then dynamically drive the cluster back to the desired state via the creation of new Pods to keep your application running.

This tutorial shows you how to run a sample app on Kubernetes using minikube. The tutorial provides a container image that uses NGINX to echo back all the requests. Objectives Deploy a sample application to minikube. Run the app. View application logs. Before you begin This tutorial assumes that you have already set up minikube. See Step 1 in minikube start for installation instructions. Note:Only execute the instructions in Step 1, Installation.

This tutorial shows you how to run a standalone kubelet instance. You may have different motivations for running a standalone kubelet. This tutorial is aimed at introducing you to Kubernetes, even if you don't have much experience with it. You can follow this tutorial and learn about node setup, basic (static) Pods, and how Kubernetes manages containers. Once you have followed this tutorial, you could try using a cluster that has a control plane to manage pods and nodes, and other types of objects.

Objectives Learn what a Kubernetes cluster is. Learn what Minikube is. Start a Kubernetes cluster on your computer. Kubernetes Clusters Kubernetes is a production-grade, open-source platform that orchestrates the placement (scheduling) and execution of application containers within and across computer clusters. Kubernetes coordinates a highly available cluster of computers that are connected to work as a single unit. The abstractions in Kubernetes allow you to deploy containerized applications to a cluster without tying them specifically to individual machines.

Production-Grade Container Orchestration

Configuring the aggregation layer allows the Kubernetes apiserver to be extended with additional APIs, which are not part of the core Kubernetes APIs. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:

Note This tutorial applies only for new clusters. Pod Security is an admission controller that carries out checks against the Kubernetes Pod Security Standards when new pods are created. It is a feature GA'ed in v1.25. This tutorial shows you how to enforce the baseline Pod Security Standard at the cluster level which applies a standard configuration to all namespaces in a cluster. To apply Pod Security Standards to specific namespaces, refer to Apply Pod Security Standards at the namespace level.

This page shows how to create an external load balancer. When creating a Service, you have the option of automatically creating a cloud load balancer. This provides an externally-accessible IP address that sends traffic to the correct port on your cluster nodes, provided your cluster runs in a supported environment and is configured with the correct cloud load balancer provider package. You can also use an Ingress in place of Service.
