[Docker入门-1] Docker CE for Ubuntu hello-world

时间 2020-01-26 标签 docker 入门 ubuntu hello world

环境

Ubuntu Server 16.04(LTS) amd64web

卸载旧版本

sudo apt-get remove docker docker-engine docker.io containerd runc

It’s OK if apt-get reports that none of these packages are installed.docker

存储驱动

默认就行ubuntu

安装Docker CE

一、更新包索引windows

sudo apt update

二、安装依赖包bash

$ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

三、添加Docker的官方GPG密钥curl

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

经过搜索指纹的最后8个字符，验证您如今拥有带指纹的密钥tcp

sudo apt-key fingerprint 0EBFCD88

四、Docker stable 稳定版本svg

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable" && apt-get update

五、经过运行hello-world 映像验证是否正确安装了Docker CEurl

sudo docker run hello-world

六、基本操做

普通用户权限（eg. user:ubuntu）

sudo usermod -aG docker ubuntu

Window10 下Linux子系统，Docker问题

ubuntu@DESKTOP-LJ47B6Q:~$ docker run hello-world
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.
ubuntu@DESKTOP-LJ47B6Q:~$ sudo systemctl start docker
[sudo] password for ubuntu:
System has not been booted with systemd as init system (PID 1). Can't operate.
ubuntu@DESKTOP-LJ47B6Q:~$

报错内容：

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
System has not been booted with systemd as init system (PID 1). Can’t operate.

上图中相关指令：

export PATH="$HOME/bin:$HOME/.local/bin:$PATH"
export PATH="$PATH:/mnt/c/Program\ Files/Docker/Docker/resources/bin"
alias docker=docker.exe
alias docker-compose=docker-compose.exe

$ docker -H tcp://0.0.0.0:2376 images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

$ echo >> ~/.bashrc <<EOF
# Connect to Docker on Windows
export DOCKER_HOST=tcp://192.168.99.100:2376  // your Docker IP
export DOCKER_CERT_PATH=/mnt/c/Users/YOUR_USERNAME/.docker/machine/certs
export DOCKER_TLS_VERIFY=1
export DOCKER_HOST='tcp://0.0.0.0:2375'
EOF
$ source ~/.bashrc

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
