目录 [toc] 什么是Kubeadm?   大多数与 Kubernetes 的工程师，都应该会使用 kubeadm 。它是管理集群生命周期的重要工具，从创建到配置再到升级; kubeadm 处理现有硬件上的生产集群的引导，并以最佳实践方式配置核心 Kubernetes 组件，以便为新节点提供安全而简单的连接流程并支持轻松升级。   在 Kubernetes 的文档 Creating a single master cluster with kubeadm 中已经给出了目前kubeadm的主要特性已经处于 Beta 状态了，在 2018 年就会转换成正式发布 (GA) 状态态，说明 kubeadm 离可以在生产环境中使用的距离越来越近了。    什么是容器存储接口(CSI)?   容器存储接口最初于 1.9 版本中作为 alpha 测试功能引入，在 1.10 版本中进入 beta 测试，如今终于进入 GA 阶段正式普遍可用。在 CSI 的帮助下， Kubernetes 卷层将真正实现可扩展性。通过 CSI ，第三方存储供应商将可以直接编写可与 Kubernetes 互操作的代码，而无需触及任何 Kubernetes 核心代码。事实上，相关规范也已经同步进入 1.0 阶段。    什么是CoreDNS?   在1.11中，官方宣布 CoreDNS

PHP app cannot connect to docker mysql container at 127.0.0.1

由 橙三吉。 提交于 2021-02-19 04:18:39
问题 Mysql is in it's own docker-compose.yml as I want a mysql server up and running that any other php application can connect to. So I do not have php and mysql in the same docker-compose.yml. From the php application, I can connect to mysql if I use the mysql container's gateway ip address by looking it up and then hard coding it into the php application. docker inspect mysql-db . But docker will change that 172... ip address each time mysql restarts so that is not ideal for development. I can

Why is a folder created by WORKDIR owned by root instead of USER

由 五迷三道 提交于 2021-02-19 03:59:48
问题 I have the following Dockerfile ARG DEV_USER=dev # Other stuff ... USER $DEV_USER # Other stuff ... WORKDIR /home/$DEV_USER/Projects When I start a container and execute ls /home/dev , the Projects folder is owned by root . Does WORKDIR ignore the fact that USER was invoked earlier? 回答1: I failed to find detail documents for this, but I'm interested on this, so I just had a look for docker source code, I guess we can get the clue from sourcecode: moby/builder/dockerfile/dispatcher.go (Line
