Starting with Dynatrace Cluster version 1.215 , Dynatrace Operator manages the lifecycle of several Dynatrace components such as OneAgent and Kubernetes API Monitor. Additional components will be added as new observability features become available.
For the automatic application-only deployment via the OneAgentAPM custom resource, support for migration is in development.
Before you begin
Understand and configure the DynaKube custom resource
The DynaKube custom resource (CR) replaces the OneAgent custom resource. The DynaKube CR follows the "don't repeat yourself" (DRY) principle to deploy a number of different components to your Kubernetes cluster.
The image below reflects the differences between the two CRs, what changes from the old CR to the new one (marked with green), and what stays the same in both CRs (marked with blue).
Global parameters (
The following settings are global, shared by every component, and located under
Tokens must point to an existing secret.
OneAgent parameters (
The following OneAgent parameters, located on the top level
spec in the OneAgent CR, move to
.spec.oneAgent in the DynaKube CR:
disableAgentUpdatein the OneAgent CR. The values are flipped for this field:
autoUpdate: false. The default is still to enable automatic updates.
agentVersionin the OneAgent CR.
Full-stack OneAgent parameters (
A new section for the full-stack OneAgent is located at
.spec.classicFullStack and must include the parameter below.
All the other OneAgent parameters (such as tolerations, arguments, DNS, and resource settings) are also located in the
.spec.classicFullStack section and are unique to the full-stack installation.
Migrate from OneAgent Operator to Dynatrace Operator
After you configure the Dynakube custom resource, follow the migration instructions below.
- Install Dynatrace Operator.
oc apply -f https://github.com/Dynatrace/dynatrace-operator/releases/latest/download/openshift.yaml
- Migrate to the DynaKube custom resource.
oc apply -f myMigratedDynaKubeCR.yaml -n dynatrace
- Delete OneAgent Operator.
oc delete -f https://github.com/Dynatrace/dynatrace-oneagent-operator/releases/latest/download/openshift.yaml
