aliyun coreos update 阿里云升级coreos

[Krast Blue]

阿里云升级难点在GFW。。。

思路：

自建代理  lantern 容器

自建升级服务器  nginx容器

阿里云默认CoreOS版本为681.2.0

查看CoreOS版本

iZ112hg7i1tZ / # cat /etc/os-release

NAME=CoreOS

ID=coreos

VERSION=681.2.0

VERSION_ID=681.2.0

BUILD_ID=

PRETTY_NAME="CoreOS 681.2.0"

ANSI_COLOR="1;32"

HOME_URL="https://coreos.com/"

BUG_REPORT_URL="https://github.com/coreos/bugs/issues”

更改网络权限

iZ112hg7i1tZ / # chmod 777 -R /etc/systemd/network/*

iZ112hg7i1tZ / # ls -lha /etc/systemd/network/*

-rwxrwxrwx 1 root root 247 Mar 22 09:13 /etc/systemd/network/10-eth0.network

-rwxrwxrwx 1 root root 139 Mar 22 09:13 /etc/systemd/network/10-eth1.network

查看更新服务器

cat /etc/coreos/update.conf

SERVER=http://127.0.0.1/835.13.0/

GROUP=stable

查看当前使用的usr分区

iZ112hg7i1tZ / # df -h

nginx docker

获取nginx docker镜像

docker pull nginx

生成nginx配置文件

cat > /home/default.conf << EOF

server {

        error_page 405 =200 $uri;

        location / {

            root /home/coreos_updates/amd64-usr;

            autoindex on;

            autoindex_exact_size off;

            autoindex_localtime on;

            allow all;

        }

        location /amd64-usr {

            root /home/coreos_updates;

            autoindex on;

            autoindex_exact_size off;

            autoindex_localtime on;

            allow all;

    }

}

EOF

启动nginx docker容器

docker run --name nginx -p 80:80 -v /home/coreos_updates/amd64-usr:/home/coreos_updates/amd64-usr:ro -v /home/default.conf:/etc/nginx/conf.d/default.conf:ro -d nginx

update-engine前台更新

update_engine_client -update

good luck！
