+# Update Helm Chart for repo:votlha-openolt-adapter

+## HOWTO: Helm Chart Update

+   :caption: Cookbook of edits
+
+   % git clone "ssh://gerrit.opencord.org:29418/voltha-helm-charts.git"

+
+- 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.
