手把手ubuntu18.04安装docker步骤
作者：互联网
01.业务背景
使用ubuntu18.04来安装docker
02.安装什么
安装docker-engine和安装docker-compose
03.官网地址
docker的官网:https://www.docker.com
ubuntu18.04安装docker的参考地址:
https://docs.docker.com/engine/install/ubuntu/
参考文章:Install Docker Engine on Ubuntu
无须安装docker-desktop
04.安装docker
步骤01.清理旧版
如果以前安装过docker,可以将旧版本进行卸载(one line).
卸载01:
sudo apt-get remove docker docker-engine docker.io containerd runc
卸载02:
sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-compose-plugin
卸载03:
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
步骤02.创建仓库
如果你是第一次安装docker,那么需要安装docker仓库.
Update the apt package index and install packages to allow apt to use a repository over HTTPS:
执行2.1: sudo apt-get update
执行2.2: (one line)
sudo apt-get install ca-certificates curl gnupg lsb-release
Add Docker’s official GPG key:
执行2.3: sudo mkdir -p /etc/apt/keyrings
执行2.4:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
Use the following command to set up the repository:
执行2.5: (one line)
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
需要确认不同的操作系统版本号,配置的数据根本不同.
使用ubuntu18.04,因此配置是bionic.
sudo gedit /etc/apt/sources.list.d/docker.list
deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu bionic stable
步骤03.下载引擎
Install Docker Engine.
Update the apt package index, and install the latest version of Docker Engine, containerd, and Docker Compose, or go to the next step to install a specific version:
执行3.1: sudo apt-get update
执行3.2: -- 安装了三个组件.
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
To install a specific version of Docker Engine,list the available versions in the repo, then select and install:
a. List the versions available in your repo:
执行3.3:
apt-cache madison docker-ce
b. Install a specific version using the version string from the second column.for example, 5:20.10.16~3-0~ubuntu-jammy.
执行3.4的命令参考:
sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io docker-compose-plugin
参考案例:
docker-ce | 5:20.10.17~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages
docker-ce | 5:20.10.16~3-0~ubuntu-bionic | https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages
执行3.4:
sudo apt-get install docker-ce=5:20.10.17~3-0~ubuntu-bionic docker-ce-cli=5:20.10.17~3-0~ubuntu-bionic containerd.io docker-compose-plugin
步骤04.执行镜像
Verify that Docker Engine is installed correctly by running the hello-world image.
执行4.1:sudo docker run hello-world
This command downloads a test image and runs it in a container. When the container runs, it prints a message and exits.Docker Engine is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands. Continue to Linux postinstall to allow non-privileged users to run Docker commands and for other optional configuration steps.
步骤05.启动镜像
01.如何启动docker
执行命令: sudo systemctl start docker
02.查看docker进程
执行命令: ps -ef | grep docker
03.执行镜像
执行命令: sudo docker run hello-world
05.安装docker-compose
步骤01.查看python
pip3是Python中的标准库管理器,它允许你安装和管理不属于 Python标准库的其它软件包.因为在ubuntu中可能安装python2或者python3.可能存在不同的pip工具.
本文主要使用python3来做验证.
验证：pip3 -V
安装: sudo apt install python3-pip
更新：pip3 install --upgrade pip
执行验证和更新命令.
列出已安装的包: pip3 list
步骤02.安裝docker-compose
执行安装: pip install docker-compose
