I'm hoping to get started on it today, and try to get something published in the next couple of days, barring other issues coming along.

Even I created a dockerfile[1] for FM service in the last week, nevertheless, the starlingx work-flow includes some parts which I have not digested completely yet. Don Penny have helped me sending useful information related to this (Thanks for that), the interaction between OpenStack/loci system and python/wheels. However I have some gaps, for example, as staring point I have to create the docker image which will be consumed by the chart. There are some build scripts and notes that talks about this, but precisely, there are a pair of lines in the build-tools/README which makes reference to a exposed service that is not specified [2,3]. For that reason I asked for a little more detailed information about the work-flow during our meeting today. Thanks for your attention. Best regards. Mario.

Irina Mihai identified four references that she used when working on the cinder helm chart overrides. See [1] to [4] below. Also as you work on creating a helm chart for the FM service, you should look at examples of existing helm charts for a reference. 2 good examples are: * Cinder helm chart which is available in the upstream openstack-helm project [5] and uses certain defaults. We have added StarlingX specific overrides which are generated from code we added [6]. * Nova-api-proxy which is a StarlingX specific service and hence was created from scratch [7,8] Frank [1] https://docs.helm.sh/developing_charts/ [2] https://medium.com/containerum/how-to-make-and-share-your-own-helm-package-5...
