This repository contains the definitions to build images of a number of Linux distributions suitable for use with OpenStack Ironic. CircleCI is used to build these images once a month using Packer.

All builds in this repository

All builds are based on the following providers:

• qemu

• vmware_desktop

• You can find my collection of builds here

NOTE: All builds are base builds and follow the Vagrant guidelines of how a Vagrant box should be built.

If using CircleCI to automate the build process, you will need to fork this repository and edit .circleci/config.yml accordingly. Otherwise, to build locally, the following is required:

• Packer
• KVM/QEMU

There are two ways to use this repository:

• Local builds
• CI builds

There are several ways to perform a local build. Most commonly you will need to run an individual build to troubleshoot. This can be done as follows:

git clone https://github.com/rcbops/ironic_factory
cd ironic_factory
cd Ubuntu/bionic64/server
./build.sh

In the above commands, you will need to change the path from Ubuntu/bionic64/server to whatever OS and version you are troubleshooting. Optionally, you can add PACKER_LOG=1 to the build command for more verbose output.

During the build process, Packer starts a VNC server, which can be connected to for troubleshooting. The following output will tell you which port to connect to:

2019-06-24T10:54:58-05:00:     qemu: The VM will be run headless, without a GUI. If you want to
qemu: view the screen of the VM, connect via VNC without a password to
qemu: vnc://0.0.0.0:5980

Additionally, you can run all of the builds at once using the included utils.py script as follows:

python utils.py build_all

This repository also contains a configuration for scheduled builds using CircleCI. The configuration can be found at .circleci/config.yml and will need to be adjusted for your particular setup.

Within the .circleci/ansible folder are jobs to create an OnMetal host on the Rackspace Cloud that CircleCI then uses to perform the builds. Once a build is complete, the image is pushed to Rackspace Cloud Files with the following folder structure:

... snip ...
├── Ubuntu

|   ├── ubuntu-bionic64-server.qcow2
|   └── Ubuntu-cosmic64-server.qcow2
... snip ...

The files at the root of a given distribution's folder are pointers to the most recent build for that distribution. This is done by setting the X-Object-Manifest header for that file.
