Docker Swarm集群初探

由 百般思念 提交于 2020-04-07 05:54:21
前言 相信Docker技术大家都有所了解，单个Docker能发挥的作用毕竟有限，也不便于管理，所以Docker得组集群来使用才能发挥强大的技术优势。既然要组集群那就涉及诸如Docker的资源调度、管理等等一系列问题。目前涉及Docker集群的三个主要的技术无外乎Swarm、 Kubernetes 、Mesos三种。从本文开始作者将会一一实践这几种主要的Docker集群技术，话不多说，现在开始。 注意： 作者的kubernetes相关实践在此 注： 本文首发于 My 公众号 CodeSheep ，可 长按 或 扫描 下面的 小心心 来订阅 ↓ ↓ ↓ 环境准备 Mac OS X 10.13.2 Docker 17.09.1-ce-mac42 (21090) virtualbox（虚拟集群中节点时需要） boot2docker v1.8.0（在虚拟节点中起docker环境时需要） 环境搭建 节点规划如下： 我们需要4个节点（1个master + 3个slave），由于没有真实地4台物理机，所以下文中是靠 docker-machine 、 virtualbox 以及 boot2docker 来虚拟出4个独立IP地址的带docker环境的节点，大家注意！ 环境安装： Docker环境安装： Tips ： 以前Mac上一般是使用 boot2docker 这个专门为OS X上运行 Docker

Get the size of a Docker image before a pull?

问题 How does one get the size of a Docker image before they pull it to their machine? 回答1: When you search for a docker image on Docker hub, there will be 2 tabs- Repo Info and Tags . Open Tags tab and you will see the sizes of all the types of images you can pull for that image. 回答2: For image on Docker Hub: curl -s -H "Authorization: JWT " "https://hub.docker.com/v2/repositories/library/<image-name>/tags/?page_size=100" | jq -r '.results[] | select(.name == "<tag-name>") | .images[0].size' |

问题 I have a fresh install using boot2docker. (DockerToolbox was giving me the same error. After uninstalling DockerToolbox, I deleted ~/.docker and searched my whole filesystem for anything starting with "docker" and found no other configuration files where things might be hiding.) This is the second command I did, after docker run hello-world : bash-3.2$ docker run -it ubuntu /bin/bash Unable to find image 'ubuntu:latest' locally latest: Pulling from library/ubuntu 6071b4945dcf: Verifying
