Stability When you use Git to manage your Kubernetes cluster, you automatically gain a convenient audit log of all cluster changes outside of Kubernetes. An audit trail of who did what, and when to your cluster tutorial, you will need a Kubernetes cluster. This tutorial should work with any valid Kubernetes installation. This example uses three Ubuntu hosts on Digital Ocean and then installs Kubernetes with kubeadm PART 1: SPIN UP A KUBERNETES CLUSTER eBook 15 1. Create three droplets in Digital Ocean Sign up or log into Digital Ocean and create three Ubuntu instances with the following specifications: • Ubuntu 16

revert/rollback and fork in the case of a catastrophic event. Meet compliance requirements Build an audit log of all cluster changes and attribution that meets SOC 2 compliance just by using Git. Standardize Amazon Web Service (AWS) Weavework’s invented and honed GitOps to accelerate and automate the installation of production-grade Kubernetes. The Weave Kubernetes Platform (WKP) works with Amazon Elastic

the result is the same each time, so the operation is idempo- tent. In contrast, adding a line to a log file leaves multiple lines for the event, so it is not idempotent. This issue doesn’t seem obvious that get the cluster configured with the GitOps controller. The base directory contains YAML installation configuration, while overlays contain GitOps controller config- urations. There is only one overlay

manage all deployments both infrastructure changes and code, you automatically generate a full audit log of all cluster changes made outside of Kubernetes. In short, it tells you who did what, and when.

linux 下的 mv 操作之所以能跨文件系统，是因为它是通过 read 源文件，然后 write 目标文件的方式实现的：© XXX Page 10 of 15 mv $ strace -o log sh -c 'mv srcfile /tmp/dstfile' ... rename("srcfile", "/tmp/dstfile") = -1 EXDEV (Invalid cross-device
