FEATURE STATE: Kubernetes v1.11 [beta] The cloud-controller-manager is a Kubernetes control plane component that embeds cloud-specific control logic. The cloud controller manager lets you link your cluster into your cloud provider's API, and separates out the components that interact with that cloud platform from components that only interact with your cluster. By decoupling the interoperability logic between Kubernetes and the underlying cloud infrastructure, the cloud-controller-manager component enables cloud providers to release features at a different pace compared to the main Kubernetes project.

This page shows how to access clusters using the Kubernetes API. 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:

This page shows how to use Romana for NetworkPolicy. Before you begin Complete steps 1, 2, and 3 of the kubeadm getting started guide. Installing Romana with kubeadm Follow the containerized installation guide for kubeadm. Applying network policies To apply network policies use one of the following: Romana network policies. Example of Romana network policy. The NetworkPolicy API. What's next Once you have installed Romana, you can follow the Declare Network Policy to try out Kubernetes NetworkPolicy.

This page provides an overview of authentication in Kubernetes, with a focus on authentication to the Kubernetes API. Users in Kubernetes All Kubernetes clusters have two categories of users: service accounts managed by Kubernetes, and normal users. It is assumed that a cluster-independent service manages normal users in the following ways: an administrator distributing private keys a user store like Keystone or Google Accounts a file with a list of usernames and passwords In this regard, Kubernetes does not have objects which represent normal user accounts.

This document details the deprecation policy for various facets of the system. Kubernetes is a large system with many components and many contributors. As with any such software, the feature set naturally evolves over time, and sometimes a feature may need to be removed. This could include an API, a flag, or even an entire feature. To avoid breaking existing users, Kubernetes follows a deprecation policy for aspects of the system that are slated to be removed.

Production-Grade Container Orchestration

This page shows how to use kubectl to list all of the Container images for Pods running in a cluster. 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:

In this example, you will run a Kubernetes Job with multiple parallel worker processes. In this example, as each pod is created, it picks up one unit of work from a task queue, completes it, deletes it from the queue, and exits. Here is an overview of the steps in this example: Start a message queue service. In this example, you use RabbitMQ, but you could use another one. In practice you would set up a message queue service once and reuse it for many jobs.

To report a security issue, please follow the Kubernetes security disclosure process. Work on Kubernetes code and public issues are tracked using GitHub Issues. Official list of known CVEs (security vulnerabilities) that have been announced by the Security Response Committee CVE-related GitHub issues Security-related announcements are sent to the kubernetes-security-announce@googlegroups.com mailing list.
