Docker的安装与配置
Docker从1.13版本之后采用时间线的方式作为版本号，分为社区版CE和企业版EE。
社区版是免费提供给个人开发者和小型团体使用的，企业版会提供额外的收费服务，比如经过官方测试认证过的基础设施、容器、插件等。
社区版按照stable和edge两种方式发布，每个季度更新stable版本，如17.06，17.09；每个月份更新edge版本，如17.09，17.10。
一、安装docker
1、Docker 要求 CentOS 系统的内核版本高于 3.10 ，查看本页面的前提条件来验证你的CentOS 版本是否支持 Docker 。
通过 uname -r 命令查看你当前的内核版本
$ uname -r
2、使用 root 权限登录 Centos。确保 yum 包更新到最新。
$ sudo yum update
3、卸载旧版本(如果安装过旧版本的话)
$ sudo yum remove docker docker-common docker-selinux docker-engine
4、安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
5、设置yum源
$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
6、可以查看所有仓库中所有docker版本，并选择特定版本安装
$ yum list docker-ce --showduplicates | sort -r
7、安装docker
$ sudo yum install docker-ce #由于repo中默认只开启stable仓库，故这里安装的是最新稳定版17.12.0
$ sudo yum install <FQPN> # 例如：sudo yum install docker-ce-17.12.0.ce
8、启动并加入开机启动
$ sudo systemctl start docker
$ sudo systemctl enable docker
9、验证安装是否成功(有client和service两部分表示docker安装启动都成功了)
$ docker version
配置镜像加速
针对Docker客户端版本大于 1.10.0 的用户
您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://....."]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
Docker的基本使用
docker version
docker container ls -a
docker container rm <容器id>
docker ps #查看容器id
docker ps -a #查看包含退出的容器id
docker exec -it <容器id> /bin/bash #进入容器
docker logs -f <容器id> #查看日志
docker images
docker image ls
docker pull nginx
docker rmi nginx (删除镜像)
docker pull mysql (默认拉取最新的镜像)
mkdir -p /usr/local/mysqlData/test/data
mkdir -p /usr/local/mysqlData/test/conf
chmod 777 /usr/local/mysqlData/test
docker run -p 3306:3306 --name test_mysql -v /usr/local/mysqlData/test/data:/var/lib/mysql -v /usr/local/mysqlData/test/logs:/logs -e MYSQL_ROOT_PASSWORD=123456 -d mysql
Kubernetes 环境搭建 - MacOS
使用清华的 brew 镜像源
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
brew update
相关软件安装
kubectl
docker (for Mac)
minikube
virtualbox
brew update && brew install kubectl && brew cask install docker minikube virtualbox

恭喜！Minikube 为你启动了一个虚拟机，并在该虚拟机中运行了 Kubernetes 集群。
