<1> 首先配置docker容器的DNS
The cat /etc/resolv.conf command to view the vessel and the host's DNS settings, DNS settings, and a host of container should be consistent.
docker DNS setup parameters may be added when starting to set the container --dns 8.8.8.8 (present active)
Or be permanently set by the DNS parameters / etc / default / docker, and then restarted DOCKER force,
export http_proxy="http://10.1.9.100:808/"
DOCKER_OPTS="--dns 210.83.210.155 --dns 127.0.1.1"
sudo service docker restart
Is there apt.conf file <2> View the container / etc / apt / directory, the proxy configuration file:
:: HTTP :: Proxy Acquire "http://10.1.9.100:8080/";
Acquire :: :: the FTP Proxy "ftp://10.1.9.100:8080/";
Acquire :: :: HTTPS Proxy "HTTPS: //10.1.9.100:8080/ ";
if not the file, the file can be copied apt.conf the host machine to the corresponding container directory.
<3> The proxy server settings:
Some developers also problems encountered, because of the company's Proxy settings.
If readers use a Proxy, you can try to create a directory name in the /etc/apt/apt.conf.d/ container is the file 99fixbadproxy
$ Sudo gedit /etc/apt/apt.conf.d/99fixbadproxy
copy the following text into the above-mentioned document, then save and exit:
Acquire::http::Pipeline-Depth 0;
Acquire::http::No-Cache true;
Acquire::BrokenProxy true;
<4> 清cache缓存：
APT-GET Clean sudo $
$ sudo APT-GET-Missing Update --fix
<5> You can change the APT source, the Internet has a lot of domestic sources, you can change the way the search.
