Is your feature request related to a problem? Please describe.

Issue #238 implements a Helm chart for deploying one or more instances of a sample "Pet Store" application using a Secretless Broker sidecar container or an authn-k8s sidecar container.

We need scripts for building and pushing sample Pet Store application images that use various authenticator sidecars (e.g. authn-k8s client, secretless, etc).

Describe the solution you would like

Port this script: https://github.com/conjurdemos/kubernetes-conjur-demo/blob/master/6_app_build_and_push_containers.sh
to the application deployment Helm chart.

Describe alternatives you have considered

Additional context

Risks / Unknowns

• New territory: Will have to add a script to build an application that can be used with the Secrets Provider

DoD

-[ ] Scripts work for building Summon Sidecar app
-[ ] Scripts work for building Secretless broker app
-[ ] Scripts work for building Secrets Provider app

Closing this issue since:

• The Pet-store app images for Summon init and sidecar containers are already being built after PR Add reusable workflow scripts #307 was merged.
• Build of images for Secrets Provider init container will be added with PR Add secrets-provider-init sample app Helm chart #328 is merged.
• Secretless broker image should be standard latest image, using standard pet store image.
