Job for docker.service failed because the control……錯誤在文章末尾處。
首先這是我出現的問題
root@40b82f229080:~# apt-get update Err:1 http://deb.debian.org/debian buster InRelease Temporary failure resolving 'deb.debian.org' Err:2 http://security.debian.org/debian-security buster/updates InRelease Temporary failure resolving 'security.debian.org' Err:3 http://deb.debian.org/debian buster-updates InRelease Temporary failure resolving 'deb.debian.org' Reading package lists...

They have been ignored, or old ones used instead.
出現這個問題，大概率是DNS解析的問題，需要指定下dns
vim /etc/docker/daemon.json { "dns": ["114.114.114.114","8.8.8.8"] }
我是單獨添加的，所以這個文件的格式是這個樣子的，不知對不對，反正能用就對了
[root@localhost ~]# cat /etc/docker/daemon.json { "registry-mirrors":["https://sri78v3x.mirror.aliyuncs.com"] } { "dns": ["114.114.114.114","8.8.8.8"] }
可以選擇重啟下docker服務 systemctl restart docker
現在我們再進去看一下
[root@localhost ~]# docker exec -it nginx1 /bin/bash root@40b82f229080:/# apt-get install vim Reading package lists... Done Building dependency tree Reading state information...

OK，已經結局了

還有種情況，就是需要更換下apt源，否則執行update很慢
mv /etc/apt/sources.list /etc/apt/sources.list.bak cat <<EOF >/etc/apt/sources.list deb http://mirrors.ustc.edu.cn/debian stable main contrib non-free deb http://mirrors.ustc.edu.cn/debian stable-updates main contrib non-free EOF
這個是目前我找到的可以正確更新的兩個地址，來自於中國科技大學開源鏡像站，摘出來兩個能用的網址，大家可以 試試。
下面這個是清華大學開源鏡像站找到的 不過我的沒法用，可能是我復制粘貼的姿勢不對……
所以我還是用的上面的 ，親測是可用的。
# 默認注釋了源碼鏡像以提高 apt update 速度，如有需要可自行取消注釋 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

還有一種方法 是這樣，不過我還沒來得及測試：
以163 源為例，在容器內創建 etc/apνsources.list.d/163.list 文件：
cat <<EOF >/etc/apt/sources.list
deb http: //mirrors.163.com/ubuntu / bionic main restricted universe multiverse deb http: //mirrors 163.cαn/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.163.cαn/ubuntu/ bionic proposed main restricted universe multiverse deb-src http://mirrors.163.cαn/ubuntu/ bionic main restricted verse mult verse deb-src http //mirrors.163.com/ubuntu/ bionic-security mai restricted universe mul tiverse deb-src http://mirrors.163.com/ubuntu/ bionic updates main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ bionic-proposed main restricted universe multiverse
EOF

這個錯誤，網上有說什么內核問題啊，虛擬化問題啊，至少在我這里不是，我翻看了下日志，原來是因為/etc/docker/daemon.json文件格式錯誤了。導致docker服務起不來了，所以回去看看這個文件，十有八九是格式錯誤了。
