安装Docker

在ECS节点上启动容器，安装Docker。

1. 如果您安装过Docker，须先卸载机器上的docker残留，执行如下命令。

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

2. 安装依赖包。

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

3. 设置镜像。

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

4. 下载安装docker。

sudo yum install docker-ce

5. 启动运行。

sudo systemctl enable docker   # 设置开启自启
sudo systemctl start docker    # 启动Docker

启动并运行容器

1. 使用centos7.9编写dockerFile基础镜像。

FROM docker.m.daocloud.io/centos:centos7.9.2009

RUN echo "[base]" > /etc/yum.repos.d/CentOS-Base.repo \
    && echo "name=CentOS-7 - Base - mirrors.aliyun.com" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "#mirrorlist=http://mirrorlist.centos.org/?release=\$releasever&arch=\$basearch&repo=os" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "baseurl=http://mirrors.aliyun.com/centos/7/os/\$basearch/" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "gpgcheck=1" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "[updates]" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "name=CentOS-7 - Updates - mirrors.aliyun.com" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "#mirrorlist=http://mirrorlist.centos.org/?release=\$releasever&arch=\$basearch&repo=updates" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "baseurl=http://mirrors.aliyun.com/centos/7/updates/\$basearch/" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "gpgcheck=1" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "[extras]" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "name=CentOS-7 - Extras - mirrors.aliyun.com" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "#mirrorlist=http://mirrorlist.centos.org/?release=\$releasever&arch=\$basearch&repo=extras" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "baseurl=http://mirrors.aliyun.com/centos/7/extras/\$basearch/" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "gpgcheck=1" >> /etc/yum.repos.d/CentOS-Base.repo \
    && echo "gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7" >> /etc/yum.repos.d/CentOS-Base.repo

# ./emrcli.sh install cn-beijing

# docker run -dit emr:latest  tail -f /dev/null

2. 创建并运行容器。

# 在dockerfile文件所在目录执行
docker build -t liubin-centos7.9:v1
# 运行
docker run -t -i liubin-centos7.9:v1 /bin/bash

3. 安装EMR CLI。
