v1.0.2

devproxy v1.0.2

Fixed

• Runtime directory auto-creation — daemon now creates /run/devproxy/ on startup if it doesn't exist, fixing socket creation failure after WSL2 reboot

• --verbose flag for devproxy status — shows Windows IP column
• Improved devproxy doctor — colored checkmarks instead of [OK]/[FAIL]
• Better empty state — helpful message when no projects are running
• Version injected at build time via ldflags

Docs

• Added CONTRIBUTING.md
• Added issue templates (bug report, feature request)
• Added pull request template
• Updated ASCII logo in README

v1.0.0

devproxy v1.0.0

Automatic Docker port conflict resolution via per-project loopback IPs.

What it does

Assigns a unique loopback IP to each Docker Compose project and forwards TCP traffic on standard ports. No changes to docker-compose files — just docker-compose up and connect:

acme.localhost:5432   → acme's PostgreSQL
acme.localhost:6379   → acme's Redis
widgets.localhost:5432 → widgets's PostgreSQL
widgets.localhost:8001 → widgets's API

Features

• Docker Watcher — detects container start/stop events automatically via Docker socket, with reconnection and exponential backoff
• Deterministic IP assignment — FNV-1a hash maps project names to stable loopback IPs (127.10.1.1 – 127.254.254.1, ~62k slots) with collision resolution
• Embedded DNS — resolves *.localhost on 127.0.53.53:53 via systemd-resolved delegation. TTL 0, no stale cache
• TCP forwarding — pure Go forwarding with half-close support. Binds to project IPs only, never 0.0.0.0
• NixOS module — services.devproxy.enable = true and done. Handles systemd, capabilities, DNS delegation, WSL2 quirks
• Windows integration — PowerShell script generation for netsh portproxy + hosts file setup. Same hostnames work in DBeaver, browsers, etc.
• CLI — daemon, status, down, cleanup, doctor, windows-setup, windows-cleanup

Security hardening

• Sanitize project/service names in PowerShell script output to prevent injection
• Add mutex to daemon maps to prevent concurrent write panic on SIGHUP
• Restrict Unix socket permissions to 0660
• Validate loopback IPs before netlink add/remove
• Restrict collision file permissions to 0600
• Replace broad pgrep with PID file for daemon management
• Add 5s dial timeout to TCP forwarder
• Validate Docker Compose labels against allowed charset

Install

inputs.devproxy.url = "github:alysnnix/devproxy";
imports = [ inputs.devproxy.nixosModules.default ];
services.devproxy.enable = true;

Script:
