Proxies

The Replicated easy install script provides several configuration options for working with an HTTP proxy. Passing the no-proxy flag to the install script will disable all proxy discovery and configuration.

Proxy Discovery

Replicated attempts to discover an HTTP proxy by checking the following environment variables in sequence:

• HTTP_PROXY
• http_proxy
• HTTPS_PROXY
• https_proxy

If none of these is set, Replicated will prompt the user to enter a proxy address or confirm that no proxy is required.

Proxy Configuration

If a proxy address is discovered or set, Replicated will assemble a default list of NO_PROXY addresses including localhost, the address of the docker0 interface, and the address of the server running the Replicated daemon. Additional addresses can be added with the additional-no-proxy parameter, which can be specified multiple times. Note that this parameter does not accept an IP range in CIDR notation.

cat install.sh | sudo bash -s additional-no-proxy=corporate.internal additional-no-proxy=10.128.0.9

To prevent errors during image pulls, Replicated will add the HTTP_PROXY and NO_PROXY environment variables to docker and restart it.

The installer will configure the Replicated daemon and operator containers to run with the HTTP_PROXY and NO_PROXY variables set in the environment. Replicated will respect these adresses when running application ready state checks.

Replicated will add the no_proxy and NO_PROXY environment variables to all application containers. It will not add the HTTP_PROXY to any application container automatically. Use the ConsoleSetting template function to add HTTP_PROXY to the environment of any of your application containers.

        env_vars:
          - name: HTTP_PROXY
            value: {{repl ConsoleSetting "http.proxy"}}
            when: {{repl ConsoleSettingEquals "http.proxy.enabled" "1"}}
