Proxy server connectivity using default host variables

Set environment variables on the host to configure default proxy settings. The Elastic Agent uses host environment settings by default if no proxy settings are specified elsewhere. You can override host proxy settings later when you configure the Elastic Agent and Fleet settings. The following environment variables are available on the host:

The proxy URL can be a complete URL or host[:port], in which case the http scheme is assumed. An error is returned if the value is a different form.

The location where you set these environment variables is platform-specific and based on the system manager you’re using. Here are some examples to get you started. For more information about setting environment variables, refer to the documentation for your operating system.

• For Windows services, set environment variables for the service in the Windows registry.

  This PowerShell command sets the HKLM\SYSTEM\CurrentControlSet\Services\Elastic Agent\Environment registry key, then restarts Elastic Agent:

  $environment = [string[]]@(
    "HTTPS_PROXY=https://proxy-hostname:proxy-port",
    "HTTP_PROXY=http://proxy-hostname:proxy-port"
    )
  
  Set-ItemProperty "HKLM:SYSTEM\CurrentControlSet\Services\Elastic Agent" -Name Environment -Value $environment
  
  Restart-Service "Elastic Agent"
  

• For Linux services, the location depends on the distribution you’re using. For example, you can set environment variables in:

  • /etc/systemd/system/elastic-agent.service for systems that use systemd to manage the service. To edit the file, run:

    sudo systemctl edit --full elastic-agent.service
    

    Then add the environment variables under [Service]

    [Service]
    
    Environment="HTTPS_PROXY=https://my.proxy:8443"
    Environment="HTTP_PROXY=http://my.proxy:8080"
    

  • /etc/sysconfig/elastic-agent for Red Hat-like distributions that don’t use systemd.

  • /etc/default/elastic-agent for Debian and Ubuntu distributions that don’t use systemd.

    For example:

    HTTPS_PROXY=https://my.proxy:8443
    HTTP_PROXY=http://my.proxy:8080
    

After adding environment variables, restart the service.
