Fedora MirrorManager

MirrorManager2 is a rewrite of mirrormanager using flask and SQLAlchemy.

MirrorManager is the application that keeps track of the nearly 400 public mirrors, and over 300 private mirrors, that carry Fedora, EPEL, and RHEL content, and is used by rpmfusion.org, a third party repository. It automatically selects the "best" mirror for a given user based on a set of fallback heuristics.

The complete MirrorManager functionality requires generate-mirrorlist-cache and mirrorlist-server which can be found at https://github.com/adrianreber/mirrorlist-server.

Hacking

Using Tinystage

MirrorManager2 authenticates using OpenID Connect. For this, it requires an OIDC provider, and the tiny-stage environment provides that.

Download tiny-stage from Github with:

$ git clone https://github.com/fedora-infra/tiny-stage
$ cd tiny-stage

Now install Ansible, Vagrant and the vagrant-libvirt plugin from the official Fedora repos, and startup tiny-stage:

$ sudo dnf install ansible vagrant vagrant-libvirt vagrant-sshfs
$ vagrant up ipa auth

It takes a bit of time, but tiny-stage will now be installed, with dummy users and groups.

Hacking with Vagrant

Quickly start hacking on mirrormanager2 using the vagrant setup that is included in the repo is super simple.

From within main directory (the one with the Vagrantfile in it) of your git checkout of mirrormanager2, run the vagrant up command to provision your dev environment:

$ vagrant up

When this command is completed (it may take a while) you will be able to the command to start the mirrormanager server:

$ vagrant ssh -c "sudo systemctl restart mirrormanager2"

Once that is running, simply go to https://mirrormanager2.tinystage.test/ in your browser on your host to see your running mirrormanager test instance.

Manual Setup

Here are some preliminary instructions about how to stand up your own instance of mirrormanager2. All required packages for MirrorManager2 are part of Fedora or RHEL/CentOS/EPEL. In the following example we will, however use a virtualenv and a sqlite database and we will install our dependencies from the Python Package Index (PyPI).

Note: this setup still needs tiny-stage running.

First, install development dependencies:

$ sudo dnf install poetry tox

Next, install MirrorManager's dependencies:

$ poetry install

Tinystage has a self-signed certificate, it needs to be added to the known certificates:

$ curl -k https://ipsilon.tinystage.test/ca.crt >> $(poetry run python -m certifi)
$ poetry run oidc-register https://ipsilon.tinystage.test/idp/openidc/ http://localhost:5000/authorize

You should then create your own sqlite database for your development instance of mirrormanager2:

$ poetry run flask -A mirrormanager2.app db sync

If all goes well, you can start a development instance of the server by running:

$ poetry run ./runserver.py

Open your browser and visit http://localhost:5000 to check it out.

Once you made your changes please run the test suite to verify that nothing covered by tests has been broken:

$ tox
