Reference server and CLI for the fetchurl protocol: a simple content-addressable URL cache for CI and package managers.

Normative specification: fetchurl/spec (SPEC.md).

This repository implements the server (and a small CLI). It is not the protocol source of truth.

go run ./cmd/fetchurl server
# or build / use Docker — see Dockerfile

Configure storage and listen address via the CLI/server flags and env (see cmd/fetchurl and internal/app).

Clients reach the server via FETCHURL_SERVER (full base URL ready to append /:algo/:hash), per the spec.

go install github.com/fetchurl/fetchurl/cmd/fetchurl@latest

Module path: github.com/fetchurl/fetchurl.

Published by CI as ghcr.io/fetchurl/fetchurl (also tagged with release versions).

For local/SDK integration tests you can still build a local tag:

docker build -t fetchurl:local .
# or use the published image:
# FETCHURL_TEST_IMAGE=ghcr.io/fetchurl/fetchurl:latest

go test ./...
