Docker是一套提供容器(英語:Container)的軟體。

安裝

可以用這個一行指令直接安裝:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -; sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"; sudo apt update; sudo apt install -y docker-ce

另外可以加裝docker-compose:

sudo apt install -y docker-compose

或是比較新版的docker-compose:

sudo curl -L "https://github.com/docker/compose/releases/download/1.28.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose; sudo chmod 755 /usr/local/bin/docker-compose

範例

啟動一個簡單的Ubuntu環境:

docker run -i -t --rm ubuntu:latest /bin/bash

然後把APT的伺服器換掉:

perl -pi -e 's/archive.ubuntu.com/tw.archive.ubuntu.com/g' /etc/apt/sources.list
apt update -y

裝些簡單的東西:

apt install -y curl vim-nox wget
