今天我已成功按照以下说明升级 docker https://askubuntu.com/questions/472412/how-do-i-upgrade-docker。
但是,当我在浏览器中打开存储库URL https://get.docker.com/ubuntu/时,它只是一个文本页面,其中包含bash commands
列表。
我的问题是:
这个文本页面的URL如何适用?
apt是否只运行bash命令?
如果是这样,为什么会有同样的问题 命令:
" echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list
"
就像那样 https://askubuntu.com/questions/472412/how-do-i-upgrade-docker
答案 0 :(得分:5)
位于https://get.docker.com/ubuntu/的页面包含可用于安装docker
的脚本# Check that HTTPS transport is available to APT
if [ ! -e /usr/lib/apt/methods/https ]; then
apt-get update
apt-get install -y apt-transport-https
fi
# Add the repository to your APT sources
echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list
# Then import the repository key
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
# Install docker
apt-get update
apt-get install -y lxc-docker
但apt-get
使用 这个脚本,必须手动运行。
该脚本使用以下内容创建配置文件/etc/apt/sources.list.d/docker.list
:
deb https://get.docker.com/ubuntu docker main
运行apt-get update
时,将使用此配置文件,apt-get update
将使用该行并从中构建以下网址
https://get.docker.com/ubuntu/dists/docker/main/binary-amd64/Packages
软件包管理系统的软件包缓存将使用Packages
文件中描述的软件包进行更新。

Description: Linux container runtime Docker complements LXC with a high-level API which operates at the process level. It runs unix processes with strong guarantees of isolation and repeatability across servers. Docker is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.
....
最后apt-get upgrade
将下载并安装软件包。
答案 1 :(得分:-2)
如果我没弄错(我还是Linux新手),
sudo sh -c "echo deb http://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
它会将文本文件复制到http://get.docker.io/ubuntu
,然后将其粘贴到etc/apt/sources.list.d/docker.list
。然后执行shell文件。
