Bootstrap Keptn Annotations

[thisthat]

Goal

Define the set of annotations on which the Webhook Admission Controller reacts, their format, their default value, and their name.

Technical Details

The Mutating Webhook should only change manifests that are annotated with Keptn special annotations.
Keptn should track the following properties:

• instance
• application
• (micro)service / component
• version

Draft proposal of annotations with example values:

keptn.sh/instance: eu-central
keptn.sh/application: my-super-cool-application
keptn.sh/component: microservice-1
keptn.sh/version: "1.0"

Not all of these annotations are mandatory for Keptn to track the lifecycle. Hence, the goal of this research is to define the mandatory annotations and the default values for the missing ones.

Acceptance Criteria

• Decide the list of mandatory annotations
• Decide default values for missing annotations
• Define the format and names

DoD

• Document the results in the README file

According to the discussion with the team, we came to a conclusion that the keptn.sh/application and keptn.sh/component annotations will be for now mandatory. Others will be optional, as it is practically impossible to decide in the current state what annotation will the system use and what default values will they have. We can easily add them when any of them will be needed
