CMD: repo

The pig repo command is a comprehensive tool for managing package repositories. It provides functionality to manage, add, remove, create and interact with os software repos. It works on both RPM-based (EL) and Debian-based systems.

Overview

pig repo - Manage Linux APT/YUM Repo

  pig repo list                    # available repo list             (info)
  pig repo info   [repo|module...] # show repo info                  (info)
  pig repo status                  # show current repo status        (info)
  pig repo add    [repo|module...] # add repo and modules            (root)
  pig repo rm     [repo|module...] # remove repo & modules           (root)
  pig repo update                  # update repo pkg cache           (root)
  pig repo create                  # create repo on current system   (root)
  pig repo boot                    # boot repo from offline package  (root)
  pig repo cache                   # cache repo as offline package   (root)

Usage:
  pig repo [command]

Aliases:
  repo, r

Examples:

  Get Started: https://pigsty.io/ext/pig/
  pig repo add -ru                 # add all repo and update cache (brute but effective)
  pig repo add pigsty -u           # gentle version, only add pigsty repo and update cache
  pig repo add node pgdg pigsty    # essential repo to install postgres packages
  pig repo add all                 # all = node + pgdg + pigsty
  pig repo add all extra           # extra module has non-free and some 3rd repo for certain extensions
  pig repo update                  # update repo cache
  pig repo create                  # update local repo /www/pigsty meta
  pig repo boot                    # extract /tmp/pkg.tgz to /www/pigsty
  pig repo cache                   # cache /www/pigsty into /tmp/pkg.tgz


Available Commands:
  add         add new repository
  boot        bootstrap repo from offline package
  cache       create offline package from local repo
  create      create local YUM/APT repository
  info        get repo detailed information
  list        print available repo list
  rm          remove repository
  set         wipe and overwrite repository
  status      show current repo status
  update      update repo cache

Flags:
  -h, --help   help for repo

Global Flags:
      --debug              enable debug mode
  -i, --inventory string   config inventory path
      --log-level string   log level: debug, info, warn, error, fatal, panic (default "info")
      --log-path string    log file path, terminal by default

Examples

List available repo and add PGDG & Pigsty repo, then update local repo cache.

# list available modules
pig repo list

# add PGDG & Pigsty repo
pig repo add pgdg pigsty

# yum makecache or apt update
pig repo update

You’ll have to update repo metadata cache after adding new repo, you can either use the dedicate pig repo update command or use the -u|--update flag in pig repo add command.

pig repo add pigsty -u    # add pigsty repo and update repo cache

If you wish to WIPE all the existing repo before adding new repo, you can use the extra -r|--remove flag, or use the dedicate pig repo set subcommand instead of pig repo add.

pig repo add all --remove # REMOVE all existing repo and add node, pgdg, pigsty repo and update repo cache
pig repo add -r           # same as above, and missing repo/module will use the default `all` alias to add node, pgdg, pigsty repo
pig repo set              # same as above, set is a shortcut for `add --remove`, REMOVED repo files are backupped to `/etc/yum.repos.d/backup` or `/etc/apt/sources.list.d/backup`

The most brutal but reliable way to setup repo for PostgreSQL installation is to wipe all existing repo and add all the required repo with:

pig repo set -u           # wipe all existing repo and add all the required repo and update repo cache

Modules

In pigsty, all repos are organized into modules, a module is a collection of repos.

Module names may maps to different real repos on different OS distro, major version and architecture, and geo region.

Pigsty will handle all the details, you can list all repos & modules with pig repo list.

repo_modules:   # Available Modules: 19
  - all       : pigsty-infra, pigsty-pgsql, pgdg, baseos, appstream, extras, powertools, crb, epel, base, updates, security, backports
  - pigsty    : pigsty-infra, pigsty-pgsql
  - pgdg      : pgdg
  - node      : baseos, appstream, extras, powertools, crb, epel, base, updates, security, backports
  - infra     : pigsty-infra, nginx
  - pgsql     : pigsty-pgsql, pgdg-common, pgdg-el8fix, pgdg-el9fix, pgdg13, pgdg14, pgdg15, pgdg16, pgdg17, pgdg
  - extra     : pgdg-extras, pgdg13-nonfree, pgdg14-nonfree, pgdg15-nonfree, pgdg16-nonfree, pgdg17-nonfree, timescaledb, citus
  - mssql     : wiltondb
  - mysql     : mysql
  - docker    : docker-ce
  - kube      : kubernetes
  - grafana   : grafana
  - pgml      : pgml
  - groonga   : groonga
  - haproxy   : haproxyd, haproxyu
  - ivory     : ivorysql
  - local     : pigsty-local
  - mongo     : mongo
  - redis     : redis

Usually these 3 modules are required to install PostgreSQL & all the extensions:

pgdg: Official PostgreSQL Repo, with PG kernel packages, utils, and 100+ extensions.
pigsty: Pigsty Extension Repo, with 200+ extra extensions and utils.
node: Operating System Default Repo, which brings all the libraries and dependencies for PostgreSQL.

There’s a convient pesudo module alias all which includes all the 3 essential modules above. You can add all of them with pig repo add all, or a even simpler abbreviation: pig repo add.

`repo list`

Lists available repository modules and repositories that can be added to the current system.

print available repo list

Usage:
  pig repo list [flags]

Aliases:
  list, l, ls

Examples:

  pig repo list                # list available repos on current system
  pig repo list all            # list all unfiltered repo raw data


Flags:
  -h, --help   help for list

Available repos are defined in the cli/repo/assets/repo.yml, if you wish to modify the repo list, you can do so by adding your own repo.yml file to ~/.pig/repo.yml.

`repo add`

Add repository configuration files to the system.

add new repository

Usage:
  pig repo add [flags]

Aliases:
  add, a, append

Examples:

  pig repo add                      # = pig repo add all
  pig repo add all                  # add node,pgsql,infra repo (recommended)
  pig repo add all -u               # add above repo and update repo cache (or: --update)
  pig repo add all -r               # add all repo, remove old repos       (or: --remove)
  pig repo add pigsty --update      # add pigsty extension repo and update repo cache
  pig repo add pgdg --update        # add pgdg official repo and update repo cache
  pig repo add pgsql node --remove  # add os + postgres repo, remove old repos
  pig repo add infra                # add observability, grafana & prometheus stack, pg bin utils

  (Beware that system repo management require sudo / root privilege)

  available repo modules:
  - all      :  pgsql + node + infra (recommended)
    - pigsty :  PostgreSQL Extension Repo (default)
    - pgdg   :  PGDG the Official PostgreSQL Repo (official)
    - node   :  operating system official repo (el/debian/ubuntu)
  - pgsql    :  pigsty + pgdg (all available pg extensions)
  # check available repo & modules with pig repo list

Flags:
  -h, --help            help for add
      --region string   region code (default|china)
  -r, --remove          remove existing repo before adding new repo
  -u, --update          run apt update or dnf makecache

This command:

Verifies if specified modules exist and translate to real repos according to

region, distro, os major version, arch

If -r|--remove flag is provided, it will move the existing repo to backup folder:

/etc/yum.repos.d/backup for EL systems
/etc/apt/sources.list.d/backup for Debian systems

Creates repo files in the system’s repository directory

/etc/yum.repos.d/<module>.repo for EL systems
/etc/apt/sources.list.d/<module>.list for Debian systems

If -u|--update flag is provided, it will run apt update or dnf makecache to update the repo cache.

If not running as root, sudo privilege is required.

`repo set`

Same as repo add <...> --remove, remove existing repo before adding new repo.

wipe and overwrite repository

Usage:
  pig repo set [flags]

Aliases:
  set, overwrite

Examples:

  pig repo set all                  # set repo to node,pgsql,infra  (recommended)
  pig repo set all -u               # set repo to above repo and update repo cache (or --update)
  pig repo set pigsty --update      # set repo to pigsty extension repo and update repo cache
  pig repo set pgdg   --update      # set repo to pgdg official repo and update repo cache
  pig repo set infra                # set repo to observability, grafana & prometheus stack, pg bin utils

  (Beware that system repo management require sudo/root privilege)


Flags:
  -h, --help            help for set

If not running as root, sudo privilege is required.

`repo update`

Update repo cache, same as apt update or yum makecache.

update repo cache

Usage:
  pig repo update [flags]

Aliases:
  update, u

Examples:

  pig repo update                  # yum makecache or apt update
