New: Kubernetes Webhook for OneAgent injection on application-only mode

This automates the deployment of Dynatrace's application-only injection at container runtime, including a new init container, and other required configuration.

For this feature, we've also added a new Custom Resource Definition, OneAgentAPM, where you can configure the tenant and credentials to use for the injection.

The feature can be enabled by creating an OneAgentAPM object, and then adding a label oneagent.dynatrace.com/instance: <OneAgentAPM object name> to each namespace you want to monitor. All Pods created from now on that belong to those namespaces will now be processed by Operator webhook.

The Operator will:

• Add an initContainer to each Pod to be monitored, in charge of downloading the OneAgent app-only package.
• Configure the required environment variables and volumes on each container for them to have injection.
• Replicate the credentials to monitored namespaces, so that they are available for the initContainer.

Changelog

Features

• Implement webhook to inject the OneAgent in App-only mode (#234, #237, #239, #250)
  • This feature can be enabled by setting the label oneagent.dynatrace.com/instance: <oneagentapm-object-name> on the namespaces to monitor.
  • CA and server certificates are generated for the webhook by the Operator, and renewed automatically after 365 and 7 days, respectively (#244)
  • OneAgent app-only package and logs will be stored on /opt/dynatrace/oneagent-paas inside the containers by default. It can be configured with the oneagent.dynatrace.com/install-path annotation on Pods (#251)
  • OneAgent app-only package will be downloaded from the provided tenant by default. It can be configured with the oneagent.dynatrace.com/installer-url annotation on Pods (#258, #264)
  • Certificates location can be configured on the webhook server with the --certs-dir, --cert, and --cert-key command line arguments (#261)
• Added a setting to configure a NetworkZone via the CR (#270)
