Setting up Environment Proxy

If you set http and https proxy, all nodes and loadbalancer will be excluded from proxy with generating no_proxy variable in roles/kubespray-defaults/defaults/main.yml, if you have additional resources for exclude add them to additional_no_proxy variable. If you want fully override your no_proxy setting, then fill in just no_proxy and no nodes or loadbalancer addresses will be added to no_proxy.

Set proxy for http and https

http_proxy:"http://example.proxy.tld:port" https_proxy:"http://example.proxy.tld:port"

Set default no_proxy (this will override default no_proxy generation)

no_proxy: "node1,node1_ip,node2,node2_ip...additional_host"

Set additional addresses to default no_proxy (all cluster nodes and loadbalancer)

additional_no_proxy: "aditional_host,"
