R8E / HTTP Cache

HTTPS caching proxy with allowlisted upstreams, stale serving during outages, and LRU-bounded disk sized for registry artifacts.

Features

• Built for large CI artifacts
• Generic HTTP caching proxy
• Serves through upstream outages
• Safe shared caching

It also inherits the features of B19 / Ubuntu — see Features for the full list.

Quick Start

Save this as compose.yaml:

---
services:
  http-cache:
    image: docker.io/damianbuho/r8e-http-cache:latest
    ports:
      - "8080:8080"
    volumes:
      - http-cache:/app/cache
    cap_drop: [ALL]
    security_opt: [no-new-privileges:true]
    restart: unless-stopped
volumes:
  http-cache:

Then start it with docker compose up --detach.

What this provides

• Service http-cache — listens on 8080 (http) — Caching HTTP proxy
• Container image ghcr.io/damian-buho/r8e/http-cache:latest
• Container image damianbuho/r8e-http-cache:latest

Installation

Pull the published container image:

Pull from GHCR — linux/amd64, linux/arm64

docker pull ghcr.io/damian-buho/r8e/http-cache:latest

Pull from DockerHub — linux/amd64

docker pull damianbuho/r8e-http-cache:latest

Stable releases also publish X.Y.Z, X.Y and X tags — pull the precision you want to pin.

If the registries above are unreachable, pull from the origin instead:

Pull from Kiota — linux/amd64

docker pull kiota.ch/r8e/http-cache:latest

Usage

Run the service in the background, publishing its ports:

From GHCR

docker run --detach --publish 8080:8080/tcp ghcr.io/damian-buho/r8e/http-cache:latest

From DockerHub

docker run --detach --publish 8080:8080/tcp damianbuho/r8e-http-cache:latest

Building

Clone the repository with its submodules:

git clone --recurse-submodules https://github.com/damian-buho/r8e-http-cache http-cache && cd http-cache

Build the container image locally:

make container-build

• Makefile reference

Run make with no arguments for the default target; run make help to list every target.

For the local dev loop, make dev-container brings up the dev-container.

Pipeline entry points:

• make analyzed — Run the heavy analysis sweep (mutation testing, benchmarks)
• make audited — Re-scan the pinned dependencies and published artifacts for new vulnerabilities
• make check-outdated — Report every pinned dependency that lags upstream
• make release-is-ready — Run the pseudo-CI pipeline locally — build, test and scan, without publishing
