Ubuntu18 安装docker及部署docker

安装docker

用官方提供的源太慢了，所以我采用了国内的阿里云源进行安装。

修改镜像源为阿里云源：

vim /etc/apt/sources.list

阿里云镜像源：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

更新软件索引：

apt-get update

安装依赖：

sudo apt install apt-transport-https ca-certificates curl software-properties-common

安装GPG证书：

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

添加docker软件信息：

Sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

更新并安装docker-ce

sudo apt-get  update
sudo apt-get  install docker-ce

安装成功后使用docker version查看docker version查看版本信息

部署nginx

拉取官方nginx镜像

docker pull nginx

查看本地镜像

docker images

运行容器

docker run --name nginx-test -p 8080:80 -d nginx

参数说明：

–name nginx-test：容器名称。
-p 8080:80： 端口进行映射，将本地 8080 端口映射到容器内部的 80 端口。
-d nginx： 设置容器在在后台一直运行。
