Running Docker behind http proxy

Error message

dial tcp: lookup index.docker.io: no such host

HTTP Proxy

This example overrides the default docker.service file.

If you are behind a HTTP proxy server, for example in corporate settings, you will need to add this configuration in the Docker systemd service file.

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/" "NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com"

Flush changes:

$ sudo systemctl daemon-reload

Restart Docker:

$ sudo systemctl restart docker
