Thanks Mario.
If you below 2 patches can close the tasks you've taken from storyboard 2004008, please go ahead to assign other tasks from that story. 

Thanks. - cindy

Hi Folks,

This a short update about this task (I will be in holiday for our next containerization meeting).
During this week I have been exploring the scripts and tools involved in the containerization building process. This activity and the wiki page shared by Don Penny have allowed me to get a better understating of the work-flow. I have sent a PR[1] with the required files to create an image for fm-rest-api service. At this moment it is WIP due to I need to do testing.  Possibly it will require more dependencies which are not available in the wheels.cfg/tarball, I will continue working on this.
During the building tools exploration I had some issues related to network due to I am working behind a proxy, I sent a  patch[2] to set it in the docker build/run commands and avoid manually modification efforts.

Any comments, feel free to contact me.

Hi Mario,

I'm making "writing a wiki" one of my top priorities. 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.

Hi Frank,

Thank you for the information, however my doubts are oriented more to the work-flow than the Dockerfile/helm/chart/ tools. 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.

On the containers community call this morning we took an action to identify information about helm charts.  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]
