公司網絡使用代理服務器上外網。在ubuntu上用docker pull出現
$sudo docker pull busybox
Using default tag: latest
Pulling repository docker.io/library/busybox
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/busybox/images. You may want to check your internet connection or if you are behind a proxy.
的錯誤。
但是我明明已經爲ubuntu設置了http_proxy了。
查了試了半天，才知道還需要給docker單獨設代理，一下是步驟。
First, create a systemd drop-in directory for the docker service:
mkdir /etc/systemd/system/docker.service.d
Now create a file called /etc/systemd/system/docker.service.d/http-proxy.conf that
adds the HTTP_PROXY environment
variable:
[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/"
If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment
variable:
Environment="HTTP_PROXY=http://proxy.example.com:80/"
Environment="NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com"
Flush changes:
$ sudo systemctl daemon-reload
Verify that the configuration has been loaded:
$ sudo systemctl show docker --property Environment
Environment=HTTP_PROXY=http://proxy.example.com:80/
Restart Docker:
$ sudo systemctl restart docker$sudo docker pull busybox
Using default tag: latest
latest: Pulling from library/busybox
