natoboram/ipapm repository overview

⁠Inter-Planetary Advanced Package Mirror

Mirrors APT repositories to IPFS.

⁠Usage

This program downloads packages from APT repositories, mirrors them to IPFS using Kubo's Mutable FileSystem and then publishes them to IPNS. It will check for changes between previous and next versions and only download added and updated files.

To crawl APT repositories, it uses InRelease files and verifies their PGP signature. It also verifies the hash of any file downloaded from that InRelease file and from Packages & Sources files. An unsigned or incorrect repository cannot be mirrored.

⁠Installation

Binaries are available in Releases⁠ or it can be installed from source.

go install github.com/NatoBoram/ipapm@latest

Environment variables set private values while the config file sets public values.

⁠Environment variables

These are the default values:

CONFIG_DIR=~/.config/ipapm
GO_ENV=development
KUBO_API_AUTH=
KUBO_API_URL=http://localhost:5001

GO_ENV changes the logging style into JSON Lines when set to production.

KUBO_API_AUTH corresponds to API.Authorizations.api.AuthSecret in Kubo's config file. See API.Authorizations: AuthSecret⁠.

⁠Examples

KUBO_API_AUTH='bearer:RGypK3ftgjie4aglyFh034j1e1dDnlJLpp2PiQAxuZ2JuITKKfGM7F6/2428WFtp+8AqMQArl3Sirpus26gauN1G'

KUBO_API_AUTH='basic:dXNlcjpSR3lwSzNmdGdqaWU0YWdseUZoMDM0ajFlMWREbmxKTHBwMlBpUUF4dVoySnVJVEtLZkdNN0Y2LzI0MjhXRnRwKzhBcU1RQXJsM1NpcnB1czI2Z2F1TjFH'

The default config file is at /home/nonroot/.config/ipapm/config.yaml. Don't forget to mount .gpg signatures.

services:
  ipapm:
    container_name: ipapm
    env_file:
      - path: .env
      - path: .env.local
    environment:
      GO_ENV: production
    healthcheck:
      test:
        - CMD
        - /usr/local/bin/readyz

      - /usr/share/keyrings/:/usr/share/keyrings/:ro

⁠API

Two endpoints are exposed on port 9090:

• /livez
• /readyz

They respond with 204 No Content when everything is right. If Kubo cannot be contacted, then /readyz responds with 503 Service Unavailable.

⁠Development

Environment variables are loaded in the following order:

• .env.${GO_ENV}.local
• .env.${GO_ENV}
• .env.local
• .env

GO_ENV cannot be set from an .env file and must be set in the environment. It defaults to development.
