docker-deb-rpm-s3

Docker image for maintaining a private APT/YUM repository in Amazon S3.

Most of the code was extracted from the elastic/beats repository.

The image includes the following projects

• deb-s3 for APT
• rpm-s3 for YUM

Usage

Place your .deb and .rpm packages under ./packages directory. Copy your encrypted GPG key to ./conf directory.

Run the container

docker run -it --rm \
  --env="GPG_PASSPHRASE=<gpg key password>" \
  --volume `pwd`:/data \
  ennexa/deb-rpm-s3 \
  --bucket=<amazon s3 bucket> \
  --prefix=<bucket prefix> \
  --directory=/data/packages \
  --aws-access-key=<AWS_ACCESS_KEY> \
  --aws-secret-key=<$AWS_SECRET_KEY> \
  --gpg-key=/data/conf/gpgkey.asc \
  --verbose \
  "$@"

REST server

A simple REST server is also included for pushing packages to the repository programatically.

Start server

Given below is a sample docker-compose configuration for the REST server

version: "3.3"
services:
    deb-rpm-s3:
        image: ennexa/deb-rpm-s3:server
        restart: always
        volumes:
            - "./conf:/data/conf"
        environment:
            - AWS_ACCESS_KEY=<aws access key>
            - AWS_SECRET_KEY=<aws secret key>
            - BUCKET=<bucket name>
            - PREFIX=<prefix for s3 bucket>
            - GPG_PASSPHRASE=<gpg key password>
        ports:
            - 8000:8000

To start the server run

docker-compose up

The GPG key for signing should be named as gpgkey.asc and placed under ./conf directory. The GPG_PASSPHRASE environment variable is not required if the key is unencrpted.

Upload package

First we need some .deb/.rpm packages for testing. Let us download the official packages for ModPagespeed.

wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-beta_current_x86_64.rpm
wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-beta_current_amd64.deb

Now to upload the files to our new repository, run

curl -XPUT http://admin:secret@localhost:8000/mod-pagespeed-beta_current_x86_64.rpm --data-binary @mod-pagespeed-beta_current_x86_64.rpm
curl -XPUT http://admin:secret@localhost:8000/mod-pagespeed-beta_current_amd64.deb --data-binary @mod-pagespeed-beta_current_amd64.deb

HTTP Basic auth is used to prevent unauthorized access to the REST server. To add your credentials create a file named config.json under ./conf with the following content.

{
    "auth_backends": {
        "predefined": {
            "users": {
                "<username>": "<bcrypt hash>"
            }
        }
    }
}

A helper script is included for generating the bcrypt hash.

$ docker run docker.ennexa.org/ennexa/deb-rpm-s3:server gen-hash secret
$2a$10$bbUwtsMPdb.gbMvW2DCyUuvivdVbvP8ljE5859IMYY6P8pO3LKbOy

Installing packages from the repository

You can install the packages by using public url of your S3 bucket.

sudo add-apt-repository "deb https://repo.example.com/apt stable main"

Running a protected repository

You can run a private repository protected with HTTP basic auth. The serverless configuration in serverless-s3-proxy can be used to setup up an http authentication proxy for the S3 bucket. Also, add the --visibility=private flag to the docker run command to ensure that the uploaded files are not privately accessible. The configuration is based on APIGatewayS3Proxy by Sumit Maingi.

sudo add-apt-repository "deb https://admin:[email protected]/apt stable main"
