| # k8s-agents-operator | ||
|
|
||
|    | ||
|
|
||
| A Helm chart for the Kubernetes Agents Operator | ||
|
|
||
| **Homepage:** <https://github.com/newrelic/k8s-agents-operator/blob/main/charts/k8s-agents-operator/README.md> | ||
|
|
||
| ## Prerequisites | ||
|
|
||
| [Helm](https://helm.sh) must be installed to use the charts. Please refer to Helm's [documentation](https://helm.sh/docs) to get started. | ||
|
|
||
| ## Installation | ||
|
|
||
| ### Requirements | ||
|
|
||
| Add the `jetstack` and `k8s-agents-operator` Helm chart repositories: | ||
| ```shell | ||
| helm repo add jetstack https://charts.jetstack.io | ||
| helm repo add k8s-agents-operator https://newrelic.github.io/k8s-agents-operator | ||
| ``` | ||
|
|
||
| Install the [`cert-manager`](https://github.com/cert-manager/cert-manager) Helm chart: | ||
| ```shell | ||
| helm install cert-manager jetstack/cert-manager \ | ||
| --namespace cert-manager \ | ||
| --create-namespace \ | ||
| --set installCRDs=true | ||
| ``` | ||
|
|
||
| ### Instrumentation | ||
|
|
||
| Install the [`k8s-agents-operator`](https://github.com/newrelic/k8s-agents-operator) Helm chart: | ||
| ```shell | ||
| helm upgrade --install k8s-agents-operator k8s-agents-operator/k8s-agents-operator \ | ||
| --namespace k8s-agents-operator \ | ||
| --create-namespace \ | ||
| --values your-custom-values.yaml | ||
| ``` | ||
|
|
||
| ### Monitored namespaces | ||
|
|
||
| For each namespace you want the operator to be instrumented, create a secret containing a valid New Relic ingest license key: | ||
| ```shell | ||
| kubectl create secret generic newrelic-key-secret \ | ||
| --namespace my-monitored-namespace \ | ||
| --from-literal=new_relic_license_key=<NEW RELIC INGEST LICENSE KEY> | ||
| ``` | ||
|
|
||
| Similarly, for each namespace you need to instrument create the `Instrumentation` custom resource, specifying which APM agents you want to instrument: | ||
| ```yaml | ||
| apiVersion: newrelic.com/v1alpha1 | ||
| kind: Instrumentation | ||
| metadata: | ||
| labels: | ||
| app.kubernetes.io/name: instrumentation | ||
| app.kubernetes.io/created-by: k8s-agents-operator | ||
| name: newrelic-instrumentation | ||
| spec: | ||
| java: | ||
| image: ghcr.io/newrelic-experimental/newrelic-agent-operator/instrumentation-java:latest | ||
| # env: | ||
| # Example New Relic agent supported environment variables | ||
| # - name: NEW_RELIC_LABELS | ||
| # value: "environment:auto-injection" | ||
| # Example overriding the appName configuration | ||
| # - name: NEW_RELIC_POD_NAME | ||
| # valueFrom: | ||
| # fieldRef: | ||
| # fieldPath: metadata.name | ||
| # - name: NEW_RELIC_APP_NAME | ||
| # value: "$(NEW_RELIC_LABELS)-$(NEW_RELIC_POD_NAME)" | ||
| nodejs: | ||
| image: ghcr.io/newrelic-experimental/newrelic-agent-operator/instrumentation-nodejs:latest | ||
| python: | ||
| image: ghcr.io/newrelic-experimental/newrelic-agent-operator/instrumentation-python:latest | ||
| dotnet: | ||
| image: ghcr.io/newrelic-experimental/newrelic-agent-operator/instrumentation-dotnet-arm:latest | ||
| php: | ||
| image: ghcr.io/newrelic-experimental/newrelic-agent-operator/instrumentation-php:latest | ||
| ``` | ||
| In the example above, we show how you can configure the agent settings globally using ENV variables. | ||
| Global agent settings can be overridden in your deployment manifest if a different configuration is required. | ||
| ### Annotations | ||
| The `k8s-agents-operator` looks for language-specific annotations when your pods are being scheduled to know which applications you want to monitor. | ||
|
|
||
| Below are the currently supported annotations: | ||
| ```yaml | ||
| instrumentation.newrelic.com/inject-java: "true" | ||
| instrumentation.newrelic.com/inject-nodejs: "true" | ||
| instrumentation.newrelic.com/inject-python: "true" | ||
| instrumentation.newrelic.com/inject-dotnet: "true" | ||
| instrumentation.newrelic.com/inject-php: "true" | ||
| ``` | ||
|
|
||
| Example deployment with annotation to instrument the Java agent: | ||
| ```yaml | ||
| apiVersion: apps/v1 | ||
| kind: Deployment | ||
| metadata: | ||
| name: spring-petclinic | ||
| spec: | ||
| selector: | ||
| matchLabels: | ||
| app: spring-petclinic | ||
| replicas: 1 | ||
| template: | ||
| metadata: | ||
| labels: | ||
| app: spring-petclinic | ||
| annotations: | ||
| instrumentation.newrelic.com/inject-java: "true" | ||
| spec: | ||
| containers: | ||
| - name: spring-petclinic | ||
| image: ghcr.io/pavolloffay/spring-petclinic:latest | ||
| ports: | ||
| - containerPort: 8080 | ||
| env: | ||
| - name: NEW_RELIC_APP_NAME | ||
| value: spring-petclinic-demo | ||
| ``` | ||
|
