Configuring the Proxy Settings
OS X
Follow the instructions on the Setup Docker on OS X. Past the docker run hello-world
step.
From the installation documentation we know that docker-machine
actually runs in a VirtualBox VM within OS X, wrapping and hiding the older boot2docker
code. So no existing proxy configuration settings apply, and you have to duplicate them as described next.
$ docker-machine ssh default
Now the command prompt will say something like:
docker@default:~$
We need root access:
$ sudo -s
Now the command prompt will say something like:
root@default:/home/docker#
Now configure the proxy:
echo "export HTTP_PROXY=http://<proxy_address>:[port]" >> /var/lib/boot2docker/profile echo "export HTTPS_PROXY=http://<proxy_address>:[port]" >> /var/lib/boot2docker/profile
For verification:
# cat /var/lib/boot2docker/profile
Exit out of ssh session:
# exit $ exit
Restart docker-machine
:
$ docker-machine restart default
Ubuntu
Execute following command:
$ sudo echo "export HTTP_PROXY=http://<proxy_address>:[port]" >> /etc/default/docker $ sudo echo "export HTTPS_PROXY=http://<proxy_address>:[port]" >> /etc/default/docker
Restart Docker
$ sudo service docker restart
CentOS 6
Execute following command:
$ sudo echo "export HTTP_PROXY=http://<proxy_address>:[port]" >> /etc/sysconfig/docker $ sudo echo "export HTTPS_PROXY=http://<proxy_address>:[port]" >> /etc/sysconfig/docker
CentOS 7
Execute following command to create docker.service.d
folder and edit http-proxy.conf
file:
$ sudo mkdir /etc/systemd/system/docker.service.d $ sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf
Now configure the proxy:
[Service] Environment="HTTP_PROXY=http://<proxy_address>:[port]" Environment="HTTPS_PROXY=http://<proxy_address>:[port]"
Reload daemon and restart Docker:
$ sudo systemctl daemon-reload $ sudo systemctl restart docker
For verification:
$ sudo systemctl show docker --property Environment
