Application Charts

This guide explores working with application charts. App charts are reusable application templates packaged as Helm charts that allow users to deploy preconfigured applications. For more information see the application charts reference page.

View Application Charts

UI

To view all available application charts, navigate to the Application Charts page under the Advanced section of the side navigation menu.

CLI

List all application charts:

epinio app chart list

Create an Application Chart

UI

Click Create on the Application Charts page to open the creation modal. Here you can provide a name and short description which will be displayed when creating an application, a detailed description for display in the table, as well as a Helm Chart URL and/or a Helm Repo URL. You can also establish settings that will prompt the user for values during app creation if they select the corresponding chart.

CLI

Create an application chart:

epinio app chart create --name mychart \
    --short-description "My application chart" \
    --description "A longer description of my application chart" \
    --helm-repo https://charts.example.com \
    --helm-chart https://charts.example.com/mychart-1.0.0.tgz \
    --set replicaCount=2 \
    --set image.tag=latest

The --set flag takes a key=value pair and can be repeated to provide multiple values.

Edit an Application Chart

UI

Select Edit from the action menu for the row of the app chart you wish to edit. Use caution when editing charts that are being used by applications, as you may cause issues for future rebuilds.

CLI

Update an application chart. Flags you do not set leave the corresponding fields unchanged:

epinio app chart update mychart \
    --short-description "An updated description" \
    --helm-chart https://charts.example.com/mychart-1.1.0.tgz \
    --set replicaCount=3

Delete an Application Chart

UI

Open the action menu for the application chart and select Delete. Confirm the deletion.

CLI

Delete an application chart:

epinio app chart delete mychart
