I need setup the corporation proxy in order Docker can download the images from public registry.
$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
Pulling repository docker.io/library/hello-world
Error while pulling image: Get https://index.docker.io/v1/repositories/library/hello-world/images: dial tcp: lookup index.docker.io: no such host
I'm using Ubuntu 12.04 machine. I have found this answer but systemctl
is not present in Ubuntu 12.04. How can I do this?
Thanks.
From Docker official documentation,
Create a systemd
drop-in directory for the docker service:
$ sudo mkdir -p /etc/systemd/system/docker.service.d
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/"
Or, if you are behind an HTTPS proxy server, create a file called /etc/systemd/system/docker.service.d/https-proxy.conf
that adds the HTTPS_PROXY
environment variable:
[Service]
Environment="HTTPS_PROXY=https://proxy.example.com:443/"
If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY
environment variable:
[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"
Or, if you are behind an HTTPS proxy server:
[Service]
Environment="HTTPS_PROXY=https://proxy.example.com:443/" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"
Flush changes:
$ sudo systemctl daemon-reload
Restart Docker:
$ sudo systemctl restart docker
Verify that the configuration has been loaded:
$ systemctl show --property=Environment docker
Environment=HTTP_PROXY=http://proxy.example.com:80/
Or, if you are behind an HTTPS proxy server:
$ systemctl show --property=Environment docker
Environment=HTTPS_PROXY=https://proxy.example.com:443/
