encryption infrastructure, allowing them to use a set of keys for Google Cloud and internal operations. SunGard, a consulting service client, is looking forward to testing this security option on the basis of GCE for a large volume of financial market trading services.The new feature will allow SunGard to control the client's data without paying the third-party cryptographic service provider.And Google pages particularly solemnly remind potential use
addition, the problems encountered by these new versions may not be found on the Internet.
Kubernetes is not designed to be bound to the Google Cloud platform, but for the above reasons, to reduce unnecessary obstacles, we recommend using GCE as the runtime environment for the first attempt (although GCE is a charged environment ). By default, five
KubernetesKubernetes is the Google Open Source container cluster Management system, which provides application deployment, maintenance, extension mechanisms and other functions, using kubernetes can easily manage the cross-machine operation of containerized applications, the main functions are as follows:1) Use Docker for application wrapping (package), instantiation (instantiate), and run.2) Run and manage containers across machines in a clustered m

The replication controller enables the equivalent number of pods to be enabled on other host machines. Replication controller can create multiple pod replicas by Repcon templates, as well as direct replication of existing pods, which need to be associated through label selector.

Next we will explore what Kubernetes is, what it can do, and how it is done.1. What is Kubernetes

Given the popularity of Docker, Google launched Kubernetes management docker cluster, and many people are expected to try. Kubernetes is supported by a large number of companies, and the Kubernetes Cluster deployment Tool integrates the IaaS platform such as Gce,coreos,aws, which is also very convenient to deploy. Give

At present, Kubernetes's Ingress provides nginx and GCE two kinds of implementations, interested students can directly refer to the official documents, Https://githu
to the intranet forwarding. Kubernetes provides three ways of Nodeport, LoadBalancer and Ingress. Nodeport, in the previous guestbook example, the use of Nodeport has been delayed. The Nodeport principle is that kubernetes exposes a port on each node: Nodeport, the external network can access the backend service through (either node) [Nodeip]:[nodeport]. LoadBalancer, on nodeport basis,

It is
functions are as follows:
1 Use Docker for application wrapping (package), instantiating (instantiate), running (run).
2 to run and manage the containers across the machine in a cluster manner.
3 to solve the communication problem between Docker and cross machine containers.

Easy to learn: lightweight, simple, easy to understand
Portable: Supports public cloud, private cloud, hybrid cloud, and multiple cloud platforms
Scalable: Modular, pluggable, support hooks, can be any combination
Self-healing: Automatic rescheduling

The purpose of the filtering host is to filter out the host that does not meet the pod requirements, and now the filtering rules implemented in Kubernetes include the following (implemented in Kubernetes
