krz/skunky-art

 1# SkunkyArt + optional VPN egress, in a single stack.
 2#
 3# Why: DeviantArt's API (AWS CloudFront + WAF) blocks some egress IPs on the
 4# /_puppy path, which makes every DA-backed page fail with
 5# `invalid character '<' looking for beginning of value` (Go trying to
 6# json.Unmarshal a CloudFront HTML 403 page). Routing SkunkyArt's outbound
 7# through a non-blocked VPN exit fixes it without any code change: devianter's
 8# HTTP client honors HTTPS_PROXY/HTTP_PROXY.
 9#
10# The VPN sidecar (gluetun) is OPTIONAL — it only starts under the "vpn" profile.
11# With the profile off, SkunkyArt runs exactly as the stock compose.yaml (direct).
12#
13# The VPN provider is YOUR choice: gluetun supports AirVPN, Mullvad, ProtonVPN,
14# PIA, and many others. Set VPN_SERVICE_PROVIDER and supply that provider's
15# required settings. Provider list + required variables:
16#   https://github.com/qdm12/gluetun-wiki
17#
18# ---------------------------------------------------------------------------
19# Setup:
20#   1. Copy this file to compose.yaml (or run with `-f compose.vpn_example.yml`).
21#   2. Create a .env next to it (and `echo ".env" >> .gitignore`):
22#
23#        # toggle VPN: uncomment both to route SkunkyArt through the VPN
24#        #COMPOSE_PROFILES=vpn
25#        #SKUNKY_PROXY=http://gluetun:8888
26#
27#        # pick your provider (see the gluetun wiki for the exact name/vars)
28#        VPN_SERVICE_PROVIDER=airvpn
29#        VPN_TYPE=wireguard
30#
31#        # WireGuard credentials (from your provider's config generator)
32#        VPN_PRIVATE_KEY=<[Interface] PrivateKey>
33#        VPN_PRESHARED_KEY=<[Peer] PresharedKey>   # optional; some providers omit it
34#        VPN_ADDRESSES=<[Interface] Address, e.g. 10.128.x.x/32>
35#        VPN_COUNTRIES=Netherlands
36#        TZ=America/Chicago
37#
38#   3. VPN on:  uncomment the two toggle lines, then `docker compose up -d`.
39#      VPN off: leave them commented, then `docker compose up -d`.
40#
41# Verify an exit is not blocked BEFORE trusting it:
42#   curl -x http://127.0.0.1:8888 -s -o /dev/null -w "%{http_code}\n" \
43#     "https://www.deviantart.com/_puppy/dabrowse/networkbar/rfy/deviations?page=0"
44#   400 (JSON "csrf: missing") = clean exit.  403 (text/html) = blocked, rotate servers.
