This commit adds a new field
ProxyFromEnvironment
to theHTTPClientConfig
andOAuth2
structs to enable Prometheus to use the default proxy from the environment variable (as specified in net/http ProxyFromEnvironment.) This is opt-out by default, so does not change anything for existing users.This change is necessary because Prometheus previously had insufficient behavior to avoid proxying EC2 metadata requests when
proxy_url
is set inec2_sd_configs
.See prometheus/prometheus#11991
