如何在Debian中安装并使用Docker容器

在Debian中安装并使用Docker容器

Docker是一个开源的容器化平台，它允许开发者将应用程序及其依赖项打包到一个可移植的容器中，然后在任何支持Docker的系统上运行，本文将介绍如何在Debian系统中安装和配置Docker，以及如何使用Docker容器。

安装Docker

1、更新系统软件包列表

在开始安装Docker之前，首先需要更新Debian系统的软件包列表，打开终端，输入以下命令：

sudo aptget update

2、安装依赖项

Docker需要一些依赖项才能正常工作，输入以下命令安装这些依赖项：

sudo aptget install 
    apttransporthttps 
    cacertificates 
    curl 
    gnupg 
    lsbrelease

3、添加Docker官方仓库

接下来，需要添加Docker官方仓库的GPG密钥，输入以下命令：

curl fsSL https://download.docker.com/linux/debian/gpg | sudo gpg dearmor o /usr/share/keyrings/dockerarchivekeyring.gpg

4、添加Docker仓库源

将Docker仓库源添加到sources.list文件中，输入以下命令：

echo 
  "deb [arch=$(dpkg printarchitecture) signedby=/usr/share/keyrings/dockerarchivekeyring.gpg] https://download.docker.com/linux/debian $(lsb_release cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

5、再次更新软件包列表

更新软件包列表后，可以开始安装Docker了，输入以下命令：

sudo aptget update

6、安装Docker Engine

现在可以安装Docker Engine了，输入以下命令：

sudo aptget install dockerce dockercecli containerd.io

7、启动Docker服务

安装完成后，需要启动Docker服务，输入以下命令：

sudo systemctl start docker

8、设置Docker开机自启

为了让Docker在系统启动时自动运行，需要将其设置为开机自启，输入以下命令：

sudo systemctl enable docker

使用Docker容器

1、拉取镜像

要使用Docker容器，首先需要从Docker Hub或其他镜像仓库拉取一个镜像，拉取一个Ubuntu镜像，输入以下命令：

docker pull ubuntu:latest

2、查看镜像列表

可以使用docker images命令查看已拉取的镜像列表，输入以下命令：

docker images

3、创建容器

使用docker run命令创建一个新的容器，创建一个名为mycontainer的Ubuntu容器，输入以下命令：

docker run d name mycontainer ubuntu:latest /bin/bash c "while true; do echo 'Hello, World!'; sleep 1; done" &> /dev/null & disown %1; docker ps a; docker logs mycontainer; docker stop mycontainer; docker rm mycontainer; docker rmi ubuntu:latest; exit; clear; history; cat /proc/meminfo; free m; df h; uname a; uptime; date; whoami; cat /etc/osrelease; cat /etc/*release; cat /proc/version; cat /proc/cpuinfo; cat /proc/mounts; cat /proc/net/dev; cat /proc/sys/kernel/hostname; cat /proc/sys/kernel/ostype; cat /proc/sys/kernel/version; cat /proc/sys/kernel/domainname; cat /proc/sysrqtrigger; cat /proc/swaps; cat /proc/loadavg; cat /proc/uptime; cat /proc/stat; cat /proc/self/status; cat /proc/self/cpuset; cat /proc/self/cgroup; cat /proc/self/ns; cat /proc/cmdline; lsblk; lsmod; modinfo $(lsmod); dmesg | tail n 1000000000000000000000000000000000000000000000000000000000000000; top bn1 | head n 5; htop bn1 | head n 5; iostat xm 1 2 | head n 5; netstat antp | head n 5; ifconfig | head n 5; route n | head n 5; dig +short myip.opendns.com @resolver1.opendns.com. resolver1.opendns.com (42.223.169.83); dig +short myip.opendns.com @resolver1.opendns.com.anycast.opendns.com (2620:119:35::35); dig +short myip6.opendns.com @resolver1.opendns.com. resolver1.opendns.com (42.223.169.83); dig +short myip6.opendns.com @resolver1.opendns.com.anycast.opendns.com (2620:119:35::35); wget http://www.google.com O | wc l; wget http://www.baidu.com O | wc l; wget http://www.bing.com O | wc l; wget http://www.yahoo.com O | wc l; wget http://www.yandex.ru O | wc l; wget http://www.msn.com O | wc l; wget http://www.live.com O | wc l; wget http://www.qq.com O | wc l; wget http://www.aliyun.com O | wc l; wget http://www.huaweicloudapis.com O | wc l; wget http://www.appleidpreviewerapitestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapigatewaytestclientappserviceprodus2aapi
