We’re going to be using CentOS 7 on a cloud server for this installation.
Port 9000 must be open and accessible from the Internet so that GitHub can communicate with the Zuul web service.
Login to your environment¶
Since we’ll be using a cloud image for CentOS 7, our login user will
centos which will also be the staging user for installation of
Zuul and Nodepool.
To get started, ssh to your machine as the
Certain packages needed for Zuul and Nodepool are not available in upstream CentOS 7 repositories so additional repositories need to be enabled.
The repositories and the packages installed from those are listed below.
ius-release: python35u, python35u-pip, python35u-devel
First, make sure the system packages are up to date, and then install some packages which will be required later. Most of Zuul’s binary dependencies are handled by the bindep program, but a few additional dependencies are needed to install bindep, and for other commands which we will use in these instructions.
sudo yum update -y sudo systemctl reboot sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm sudo yum install -y git2u-all python35u python35u-pip python35u-devel java-1.8.0-openjdk sudo alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 10 sudo alternatives --install /usr/bin/pip3 pip3 /usr/bin/pip3.5 10 sudo pip3 install python-openstackclient bindep
Nodepool uses Zookeeper to keep track of information about the resources it manages, and it’s also how Zuul makes requests to Nodepool for nodes.
