Docker CE的安装——Ubuntu/Contos

Ubuntu

1.安装系统工具

sudo apt-get update sudo apt-get install ca-certificates curl gnupg

2.信任Docker的GPG公钥

sudo install -m 0755 -d /etc/apt/keyrings curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg sudo chmod a+r /etc/apt/keyrings/docker.gpg

3.写入软件源信息

echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

4.安装Docker

sudo apt-get update sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

5.查看信息

docker version

6.配置镜像加速

1）创建文件夹

sudo mkdir -p /etc/docker/

2）配置镜像加速内容

sudo cat > /etc/docker/daemon.json << EOF { "registry-mirrors": [ "https://docker.hpcloud.cloud", "https://docker.m.daocloud.io", "https://docker.unsee.tech", "https://docker.1panel.live", "http://mirrors.ustc.edu.cn", "https://docker.chenby.cn", "http://mirror.azure.cn", "https://dockerpull.org", "https://dockerhub.icu", "https://hub.rat.dev" ] } > EOF

3)重新加载

sudo systemctl daemon-reload

4）重启docker

sudo systemctl restart docker

Contos

1.安装系统工具

sudo yum install -y yum-utils

2.添加软件源信息

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

3.安装docker

sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

4.开启Docker服务

sudo service docker start

5.配置镜像加速

1）配置文件

sudo mkdir -p /etc/docker/ sudo cat > /etc/docker/daemon.json << EOF > { > "registry-mirrors": [ > "https://docker.hpcloud.cloud", > "https://docker.m.daocloud.io", > "https://docker.unsee.tech", > "https://docker.1panel.live", > "http://mirrors.ustc.edu.cn", > "https://docker.chenby.cn", > "http://mirror.azure.cn", > "https://dockerpull.org", > "https://dockerhub.icu", > "https://hub.rat.dev" > ] > } > EOF

2）重新加载并重启docker

sudo systemctl daemon-reload sudo systemctl restart docker

6.查看Docker信息

docker version 查看docker版本号

docker images 查看docker镜像

docker ps 查看docker容器
