## HOWTO: Helm Chart Update

.. code-block:: shell-session
   :caption: Cookbook of edits

   % git clone "ssh://gerrit.opencord.org:29418/voltha-helm-charts.git"
   % cd voltha-helm-charts
   % vi $(grep -r 'adapter' . | cut -d: -f1 | sort -u)

   % make lint-chart
   % make lint-helm

- Increment repository `VERSION file <https://gerrit.opencord.org/plugins/gitiles/voltha-openolt-adapter/+/refs/heads/master/VERSION>`_.  Build, test and deploy.
- Modify repo:voltha-helm-charts

  - Update component version in the component chart file.
  - Update chart version for all charts dependent on the component chart.
  - Run ``make lint-chart lint-helm`` to validate chart changes.
  - chart:voltha, chart:voltha-infra and chart:voltha-stack can be confusing
    due to a layer of indirection:

    - chart:voltha-{infra,stack} are not not named for code repositories,
      they are a container chart used to capture a list of dependencies
      and versions.
    - chart:voltha depends on these two charts which in turn depend on
      sets of voltha components & versions.
    - When ``make lint-chart`` report this error

      - [ERROR] Chart modified but version unchanged: voltha/Chart.yaml (2.12.11)
      - It will imply that a component like openolt-adapter has been updated
        but chart:voltha and chart:voltha-{infra,stack} have not.
