Використання змінних середовища HTTP_PROXY / HTTPS_PROXY

# HTTP proxy endpoint (port 3128) with inline auth
export HTTP_PROXY="http://USER:[email protected]:3128"
export HTTPS_PROXY="http://USER:[email protected]:3128"
# curl and some tools only read the lowercase form — set both
export http_proxy="$HTTP_PROXY"
export https_proxy="$HTTPS_PROXY"

# Never send local / internal traffic through the proxy
export NO_PROXY="localhost,127.0.0.1,::1,.internal,169.254.169.254"
export no_proxy="$NO_PROXY"

# Now normal commands go through the proxy
curl https://api.ipify.org      # prints the proxy exit IP, not yours
wget -qO- https://api.ipify.org

# One-off, without exporting anything:
curl -x http://USER:[email protected]:3128 https://example.com

# SOCKS5 (port 1080). socks5h makes DNS resolve AT the proxy,
# so your origin never leaks the hostname lookup.
export ALL_PROXY="socks5h://USER:[email protected]:1080"
curl https://api.ipify.org

# --- Python: requests, urllib, pip and httpx honor the env vars ---
import requests
print(requests.get("https://api.ipify.org").text)   # proxy exit IP

# Override per-request (this ignores the env vars):
proxies = {
    "http":  "http://USER:[email protected]:3128",
    "https": "http://USER:[email protected]:3128",
}
requests.get("https://api.ipify.org", proxies=proxies)

# SOCKS5 needs the extra:  pip install "requests[socks]"
proxies = {"https": "socks5h://USER:[email protected]:1080"}


# --- Node.js (>=18): core fetch does NOT read HTTP_PROXY on its own ---
// import { ProxyAgent, setGlobalDispatcher } from "undici";
// setGlobalDispatcher(
//   new ProxyAgent("http://USER:[email protected]:3128"));
// const r = await fetch("https://api.ipify.org");
// console.log(await r.text());        // proxy exit IP
//
// To make libraries respect the env vars instead:
//   npm i global-agent
//   GLOBAL_AGENT_HTTP_PROXY=$HTTP_PROXY node -r global-agent/bootstrap app.js

# Build-time: forward the proxy into the build
docker build \
  --build-arg HTTP_PROXY="http://USER:[email protected]:3128" \
  --build-arg HTTPS_PROXY="http://USER:[email protected]:3128" \
  --build-arg NO_PROXY="localhost,127.0.0.1" .

# Runtime: inject into the running container
docker run --rm \
  -e HTTP_PROXY="http://USER:[email protected]:3128" \
  -e HTTPS_PROXY="http://USER:[email protected]:3128" \
  -e NO_PROXY="localhost,127.0.0.1" \

# The Docker daemon itself (image pulls) reads ~/.docker/config.json:
