在docker 容器中執行apt-get update有時候會報錯，固然形成錯誤的緣由有不少狀況，具體狀況具體分析，docker
APT Hash sum mismatch錯誤的常看法決方法總結這篇博客寫的不錯，在此感謝博主提供的思路。ubuntu
如下是本人解決docker容器中執行apt-get update報錯的解決辦法（踩了好多坑，血淋淋的阿，終於好用了。）：緩存

<1> 首先配置docker容器的DNS服務器
cat /etc/resolv.conf 該命令查看容器和宿主機的DNS設置，容器和宿主機的DNS設置應該一致。fetch
docker DNS的設置能夠經過啓動容器時添加參數 --dns 8.8.8.8 來設置（本次有效）ui
或者經過 /etc/default/docker的DNS參數來進行永久設置，而後重啓DOCKER生效，代理
export http_proxy="http://10.1.9.100:808/"
DOCKER_OPTS="--dns 210.83.210.155 --dns 127.0.1.1"rest
sudo service docker restartdns
<2> 查看容器 /etc/apt/目錄中是否有apt.conf文件，該文件配置了代理：ip
Acquire::http::proxy "http://10.1.9.100:8080/";
Acquire::ftp::proxy "ftp://10.1.9.100:8080/";
Acquire::https::proxy "https://10.1.9.100:8080/";
若是沒有該文件，能夠將宿主機中的apt.conf文件拷貝到容器對應目錄中。
<3>對代理服務器進行設置：
還有些開發者遇到的問題，是由於公司的Proxy的設置。
若是讀者朋友使用了Proxy，那麼能夠嘗試，在容器的 /etc/apt/apt.conf.d/ 目錄下建立一個名稱爲99fixbadproxy 的文件
$ sudo gedit /etc/apt/apt.conf.d/99fixbadproxy
把如下文本複製到上述文件中，而後保存退出：
Acquire::http::Pipeline-Depth 0;
Acquire::http::No-Cache true;
Acquire::BrokenProxy true;
<4> 清cache緩存：
$ sudo apt-get clean $ sudo apt-get update --fix-missing <5> 能夠更改APT源，網上有挺多的國內源，能夠搜索更改辦法。
