Docker Proxy Configuration
==========================
StarlingX uses publicly available container runtime registries. If you are
behind a corporate firewall or proxy, you need to set proxy settings.
For example, if the StarlingX OAM interface or network is behind an http/https
proxy, relative to the Docker registries used by StarlingX or applications
running on StarlingX, then Docker within StarlingX must be configured to use
these http/https proxies.

Proxy overview

The figure below shows how proxies are used in StarlingX.

:alt: StarlingX proxy usage
*Figure 1: StarlingX proxy usage*
The items labeled *a* and *b* in the figure indicate two configuration files:
* Configuration file *a* lists sysadmin shell proxy environment variables.
This file is not required for StarlingX bootstrap or any StarlingX
operations. You **must** manually add this file if you are accessing the
public network via a proxy. You **must** add the following StarlingX
specific IP addresses to the no_proxy list:
* registry.local
* {controller OAM gateway IP/floating IP/host IP}
* {controller management floating IP/host IP}
* {controller cluster gateway IP}
* 10.96.0.1 {apiserver cluster IP for Kubernetes}
* 10.96.0.10 {coredns cluster IP for Kubernetes}
* `*.cluster.local`
* Configuration file *b* lists container runtime proxy variables
(docker_proxy). Configure these variables in the ``localhost.yml`` file
before Ansible bootstrap. This file is **required** if you are accessing
the public network via a proxy. StarlingX specific IP addresses will be
automatically added to the no_proxy list.
The numbered items in the figure indicate the process flow:
#. In the ``localhost.yml`` file, fill in the Docker proxy section for
configuration file *b*.
#. The bootstrap process is responsible for pulling Docker images from either:
* the public registry using the proxy setting in (1) or
* the private registry within the company/organization network.
The bootstrap process will push to the registry.local afterwards.
#. After the Kubernetes API server is running, the bootstrap process will
communicate with it for further StarlingX configuration. You **must** ensure
the cluster network gateway is set for no_proxy in configuration file *a*.
#. After StarlingX provisioning is complete, any operations that pull Docker
images will use configuration file *b*. All other operations, including
kubectl and system operations, will use the sysadmin shell and
configuration file *a*.
----------------------
Set proxy at bootstrap
----------------------
To set the Docker proxy at bootstrap time, refer to
:doc:`Ansible Bootstrap Configurations <../deploy_install_guides/r3_release/ansible_bootstrap_configs>`.
------------------
Set HTTP proxy URL
------------------
To specify the HTTP proxy URL, use the commands:
::
system service-parameter-modify platform docker http_proxy http://my.proxy.com:1080
system service-parameter-apply platform
-------------------
Set HTTPS proxy URL
-------------------
To specify the HTTPS proxy URL, use the commands:
::
system service-parameter-modify platform docker https_proxy https://my.proxy.com:1443
system service-parameter-apply platform
-------------------------
Set no_proxy address list
-------------------------
A no_proxy address list can be provided for registries not on the other side
of the proxies. This list will be added to the default no_proxy list derived
from localhost, loopback, management, and OAM floating addresses at runtime.
Due to a Docker restriction, each address in the no_proxy list must not be in
subnet format and it cannot contain a wildcard. For example:
To specify a no_proxy list, use the commands:
::
system service-parameter-modify platform docker no_proxy: 1.2.3.4, 5.6.7.8
system service-parameter-apply platform
