In this article, we will explain how to setup a sandbox in order to experiment with Software Factory. The following article explains how to setup a CentOS 7 virtual machine guest based on VirtualBox. Feel free to adapt the following to the hypervisor of your choice. The sandbox guest will be configured to be accessible from your host only.

This article is part of the Zuul hands-on series.

Create the virtual machine

The first step is to create a CentOS 7 virtual machine.

  • download the CentOS 7 minimal iso
  • create the virtual machine using VirtualBox Manager with the following settings:
    • 20G HDD
    • 4G RAM
    • hostname: sftests.com

During the installation process, do not forget to activate the network and set the hostname in the NETWORK & HOST NAME panel.

After the installation, shut down the virtual machine to finalize the configuration. For easy access to your instance from a terminal and browser, open the virtual machine settings in VirtualBox and create an additional network interface attached to the Host-only adapter . Then start the virtual machine, and type ip address in the virtual machine's terminal to get the network configuration:

[root@managesf.sftests.com ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    ...
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:c5:69:3c brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.15/24 brd 10.0.2.255 scope global noprefixroute dynamic enp0s3
       valid_lft 85327sec preferred_lft 85327sec
3: enp0s8: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:23:d3:1b brd ff:ff:ff:ff:ff:ff
    inet 192.168.56.102/24 brd 192.168.56.255 scope global noprefixroute dynamic enp0s8
       valid_lft 1133sec preferred_lft 1133sec

Configure access to the virtual machine

Add the IP address of the second interface and the hostname in your /etc/hosts file (ie on the VirtualBox host), for example:

192.168.56.102 sftests.com

Configure the virtual machine

You can authorize your SSH public key with the root user to allow password-less authentication:

ssh-copy-id root@sftests.com

Connect to your virtual machine from your host:

ssh root@sftests.com

Configure firewalld to allow http, https and gerrit access from your host:

firewall-cmd --add-service=http --add-service=https
firewall-cmd --add-port=29418/tcp
firewall-cmd --runtime-to-permanent

Install Software Factory

The next step is to install Software Factory. We will add hypervisor-runc to the architecture file to enable containers in check and gating jobs:

First, ensure the system is up to date before installing Software Factory:

yum update -y

Then, install Software Factory, this will take ~15 minutes to download, install and configure services:

yum install -y https://softwarefactory-project.io/repos/sf-release-3.1.rpm
yum update -y
yum install -y sf-config
echo '      - hypervisor-runc' >> /etc/software-factory/arch.yaml
sfconfig --enable-insecure-slaves

Validate https access

Connect to https://sftests.com to access to the software factory web interface

Configure admin public SSH key

The next step is to add your SSH public key to the admin account, so that you can submit reviews with the admin account. The admin password is defined in the /etc/software-factory/sfconfig.yaml file.

awk '/admin_password/ { print $2}' /etc/software-factory/sfconfig.yaml

Go to https://sftests.com/auth/login and log in as admin by clicking on Toggle login form. Then select the Gerrit link in the top menu, and click on "Settings" to edit the admin account:

Select SSH Public Keys and add your public key (Do not delete the other defined key, it's used for administrative tasks).

Snapshot the virtual machine

You can now snapshot the virtual machine to be able to quickly restore a known state after testing.
