Defining a Chart

To define your charts is not any different than helm. we do provide some post/pre actions that will help us manage our charts better.

Behavior

1. will check if chart exists
   1. if it does not exist
      • we will install the chart
   2. if exist then
      • armada will check if there are any differences in the charts
      • if the charts are different then it will execute an upgrade
      • else it will not perform any actions

Note

You can use references in order to build your charts, this will reduce the size of the chart definition will show example in multichart below
