yum安装升级docker和docker-compose_yum docker-compose

1、环境说明

centos7

docker-ce版本： docker-ce-20.10.9-3.el7

docker-comose:   1.28.4

2、卸载已有docker

yum remove -y docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

 或者

sudo yum remove docker \
docker-common \
container-selinux \
docker-selinux \
docker-engine

卸载Docker后,/var/lib/docker/目录下会保留原Docker的镜像,网络,存储卷等文件. 如果需要全新安装Docker,需要删除/var/lib/docker/目录

rm -fr /var/lib/docker/

3、安装

3.1 配置docker yum源

推荐方法1

方法1：

先安装yum-utils：

yum install -y yum-utils.noarch

然后执行：

yum-config-manager \
--add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

配置docker镜像源地址：

sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://1nj0zren.mirror.aliyuncs.com",
        "https://docker.mirrors.ustc.edu.cn",
        "http://f1361db2.m.daocloud.io",
        "https://registry.docker-cn.com"
    ]
}
EOF

再执行：

sudo systemctl daemon-reload

3.2 安装docker:

查看所有可用的docker版本:

yum list docker-ce --showduplicates | sort -r

这里我们安装 docker-ce-20.10.9-3.el7 版本

yum -y install  docker-ce-20.10.9-3.el7

查看docker版本:

docker version

安装docker命令补全工具：

yum install -y bash-completion

启动docker服务:

systemctl status docker
systemctl start docker

systemctl restart docker

设置开机自启动:

systemctl enable docker

3.3、安装docker-compose

去github上下载二进制包来安装

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

上面这个github的地址太慢了，如果你能耐得住就慢慢等。。
可以采用下面这个速度较快的方式：

curl -L https://get.daocloud.io/docker/compose/releases/download/1.28.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

你可以通过修改URL中的版本，可以自定义您的需要的版本。

将可执行权限赋予二进制文件：

chmod +x /usr/local/bin/docker-compose

创建软链接：

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

4、验证

执行命令查看安装的版本

docker-compose version

docker version
