IvC: Continuing templating

Preface

Adding templating with the ability to add files to the instance and to run scripts during the instance deployment will get us most of the way to a complete solution for our needs, so that’s what this page is about.

Code

The scripts described in this section are available in a Git repo @ https://github.com/danielfdickinson/ivc-in-the-wtg-experiments.

Section Contents

• Just a template
• Adding basic write files support
• Combining templates and write files support

Next Steps

• Add runcmd and bootcmd sections to userdata-default.yaml.jinja
• Add the full set of required files for the desired instances
• Combine with create-instances.py script
• Add public DNS updating (required to meet some dependencies) (OVH API, not OpenStack)
• Test launch the desired instances
• Improve the code & config, test, improve, etc until satisfied (for now).
• Add a wrap up note for this series.
