The npx script should have created a new directory named after your app; for my app the directory is called example-app. These can be used in the Backstage app-config.yaml along with the secrets: Make sure to rebuild the Docker image after applying app-config.yaml changes. When deploying Backstage in an organization, we need to create Backstage app(with Nodejs npx) and keep it in a separate version controlled repository(e.g git) since the customizations need to versioned and tracked. If an app developer on one team wants to understand how their feature is affecting overall app performance, theres a plugin for that: Developers can also look at crashes, releases, test coverage over time and many more tools in the same location. Before we can use it, we have to load it into the cluster. Backstage is the natural result of that focus. A Kubernetes Deployment checks on the health of your Pod and restarts the Pod's Container if it terminates. To do that: To enable it you need to provide a valid email address in the chart's values: By default, the charts use letsencrypt-staging so in the above example we instruct helm to use the production issuer To install the Backstage app, we make use of npx which is a tool to run Node executables straight from the registry.
