capabilities. 5 Clair Http://github.com/coreos/clair Clair is a container vulnerability analysis service. It provides a list of vulnerabilities that can threaten a container and sends a notification to the user when a new container vulnerability is released. 6 Weave Http://github.com/zettio/weave Weave Create a virtual network and connect to a Docker container that is deployed on multiple hosts.

At first, I was just looking for an API gateway to prevent the API from being maliciously requested, finding a lap to discover the Nginx-based openresty(Lua language) expansion module Orange is good (also found in Kong , but the feeling of complexity is useless), but also lazy to use Vagrant combined with Docker to quickly set up the environment, based on the dockerfile of others to run through the whole experiment, feel good.

Based on the idea of simplifying the architecture, we use ETCD to store IP data and operate the ETCD directly from the plugin. Complete the use and release of the IP.

This is a creation in Article, where the information may have evolved or changed. absrtact: with the advent of Docker, PaaS, CaaS (Container as A Service), and even DCOs (DataCenter OS) present an explosive development. In PAAs, because instances generally default to dynamic IPs, for 7-layer calls (such as HTTP requests), 7-tier dynamic routing is required to obtain the mapping of the application domain name (or virtual IP) and back-end instances to provide 7-tier services, and for 4-layer calls

In the first two parts of this series we describe the overall process of API server and how the API objects are stored in ETCD. In this article we will explore how to extend the API resources.In the beginning, the only way to extend the API resources is to extend the relevant API source code and integrate it into the resources you need. Or, push a whole new type into the community code for the new core object API. However, this can lead to a constant

Kubernetes can connect pods on different node nodes in the cluster, and by default, each pod is accessible to each other. However, in some scenarios, different pods should not be interoperable, and access control is required at this time. So how does it work?Brief introduction?? Kubernetes provides Networkpolicy feature, which supports network access control by namespace and by pod level. It uses the label to specify the namespaces or pod, and the underlying is implemented with Iptables. This ar

Pod is the most basic deployment dispatch unit in Kubernetes, and it can contain container, which logically represents an instance of a certain application. For example, a Web site application is built from the front end, back end, and database, and these three components will run in their respective containers, so we can create a pod containing three container. This paper will do a simple analysis of the basic processing flow of kubernetes. The pod creation process is shown in the following ill

Controller manager and scheduler. To achieve this reliably, we are want to having one actor modifying state at a time, but we want replicated instances of th ESE actors, in case a machine dies. To achieve this, we is going to use a lease-lock with the API to perform master election. We'll use --leader-elect the flags for each scheduler and Controller-manager, using a lease in the API would ensure that's only 1 ins Tance of the Scheduler and Controller-manager is running at once.That is, Control
