Using a Proxy Server
Proxy server 3128 : Trade london

In some environments, HTTP connections must pass through a proxy. The Deis builder component supports proxies by respecting the proxy-related environment variables defined in /etc/environment_proxy.

Additionally, Docker is also configured to respect the settings in this file.

By default, /etc/environment_proxy has all environment variables set to blank values:

HTTP_PROXY= HTTPS_PROXY= ALL_PROXY= NO_PROXY= http_proxy= https_proxy= all_proxy= no_proxy=


Proxy settings must be respected by the applications you’re building. When using custom buildpacks, make sure they respect proxy settings.

Configuring before server launch

Before provisioning the servers using the provision scripts in the Deis repository, edit contrib/coreos/user-data.example and replace the contents of the file to suit your environment.

For example:

- path: /etc/environment_proxy owner: core content: | HTTP_PROXY= HTTPS_PROXY= ALL_PROXY= NO_PROXY="," http_proxy= https_proxy= all_proxy= no_proxy=","

After running make discovery-url and provisioning your servers, the platform will come up with your proxy settings.

Configuring after server launch

It’s also possible to configure these settings after the server has been provisioned, but this will result in downtime of the Deis platform as components are restarted.

You’ll need to edit /etc/environment_proxy on all CoreOS hosts (as the builder component can be relocated to any host in the cluster). Then, restart Docker with sudo systemctl restart docker and monitor Deis components with deisctl list. It may be necessary to restart components if they do not recover automatically from the Docker restart.
