s33d1ing/yumrepo repository overview

⁠Docker YUM Repository

This image is based on the official NGINX⁠ image and has been modified to monitor and serve a YUM repository.

⁠Supported Architectures

Although the NGINX images support multiple architectures, this image is only built as x86-64.

⁠Usage

Here are some example snippets to help you get started creating a container.

⁠docker-compose

version: "3.8"

services:
  web-server:
    image: s33d1ing/yumrepo
    ports:
      - "80:80"
    volumes:
      - ./run/repo:/var/repo:rw
    hostname: yum-repo
    environment:
      - REPO_PORT=80
      - REPO_PATH=/var/repo
      - REPO_DEPTH=2

  centos-7:
    image: centos:centos7
    volumes:
      - ./run/container.repo:/etc/yum.repos.d/container.repo:ro
    command: yum --disablerepo=* --enablerepo=container -y install hello
    depends_on:
      - web-server

  centos-8:
    image: centos:centos8
    volumes:
      - ./run/container.repo:/etc/yum.repos.d/container.repo:ro
    command: yum --disablerepo=* --enablerepo=container -y install hello
    depends_on:
      - web-server

⁠docker cli

docker run -d --name=yum-repo -p 80:80 -v ./run/repo:/var/repo s33d1ing/yumrepo

⁠Parameters

You must mount a directory inside the container that contains all packages that you want serve. This directory may have other nested directories to respect the structure of a YUM repository (i.e. 7/x86_64, 8/x86_64). In this case, you would leave REPO_DEPTH as the default value of 2. If the repository has a flat directory structure, you would set REPO_DEPTH to 0.

Optionally, the repository's internal port and path can be changed. Keep in mind that the internal port (i.e. -p 80:80) and REPO_PORT should match. Likewise, the internal path (i.e. -v ./run/repo:/var/repo) and REPO_PATH should match.

⁠Application Setup

Once the YUM repository is running, the clients must be configured. Add the following config to /etc/yum.repos.d/container.repo on the client. Be sure to swap out yum-repo with your Docker host's or container's IP address. Then run the next command to perform an action using the container repository.

[container]
name = Container Repo
baseurl = http://yum-repo/$releasever/$basearch/
gpgcheck = 0

yum --disablerepo=* --enablerepo=container <action> <package>

⁠Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/s33d1ing/docker-yumrepo.git

cd docker-yumrepo

docker-compose up -d --build
