docker-aptly is container w
aptly backed by
aptly is a swiss army knife for Debian repository management: it allows you to mirror remote repositories, manage local package repositories, take snapshots, pull new versions of packages along with dependencies, publish as Debian repository. More info are on aptly.info and on github.
nginx is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP proxy server, originally written by Igor Sysoev. More info is on nginx.org.
The following command will run
nginx in a container:
docker run \ --detach=true \ --log-driver=syslog \ --restart=always \ --name="aptly" \ --publish 80:80 \ --volume $(pwd)/aptly_files:/opt/aptly \ --env FULL_NAME="First Last" \ --env EMAIL_ADDRESS="firstname.lastname@example.org" \ --env GPG_PASSWORD="PickAPassword" \ --env HOSTNAME=aptly.example.com \ smirart/aptly:latest

||Automatically start the container when the Docker daemon starts|
||Name of the container|
||Path that aptly will use to store its data : mapped path in the container|
||Docker host port : mapped port in the container|

Setup a client for use your repo
Fetch the public PGP key from your aptly repository and add it to your trusted repositories
wget http://YOUR_HOST_FOR_APTLY/aptly_repo_signing.key apt-key add aptly_repo_signing.key
Backup then replace /etc/apt/sources.list
cp /etc/apt/sources.list /etc/apt/sources.list.bak echo "deb http://YOUR_HOST_FOR_APTLY/ ubuntu main" > /etc/apt/sources.list apt-get update
mainmay be another. It's require from your repos on aptly.
Configure the container
For attach to the container and start to configure your aptly use:
docker exec -it aptly /bin/bash
Read the official documentation for learn more about aptly.
For stop container use:
docker stop aptly
Create a mirror of Ubuntu's main repository
- Attach to the container. How attach? See Configure the container.
By default, this script will automate the creation of an Ubuntu 14.04 Trusty repository with the main and universe components, you can adjust the variables in the script to suit your needs.
If the script fails due to network disconnects etc, just re-run it.
The initial download of the repository may take quite some time depending on your bandwidth limits, it may be in your best interest to open a screen, tmux or byobu session before proceeding.
For host a mirror of Ubuntu's main repository, you'll need upwards of 80GB+ (x86_64 only) of free space as of Feb 2016, plan for growth.
When the script completes, you should have a functional mirror that you can point a client to.
For create Debian's mirror use
Building the container
If you want to customize image or build the container locally, check out this repository and build after:
git clone https://github.com/urpylka/docker-aptly.git docker build docker-aptly
How this image/container works
All of aptly's data (including PGP keys and GPG keyrings) is bind mounted outside of the container to preserve it if the container is removed or rebuilt.
By default, Docker will map port 80 on the Docker host to port 80 within the container where nginx is configured to listen. You can change the external listening port to map to any port you like. (See Explane of the flags).
The GPG password which you specified in
GPG_PASSWORD is stored in plain text and visible as an environment variable inside the container.
It is set as an enviornment variable to allow for automation of repository updates without user interaction. The GPG password can be removed completely but it is safer to encrypt the GPG keyrings because they are bind mounted outside the container to avoid the necessity of regenerating/redistributing keys if the container is removed or rebuilt.
