Deploy the AppDynamics Operator on Kubernetes

To deploy the AppDynamics Operator on Kubernetes, open a command prompt and follow these steps:

(If you are not on Kubernetes, see Deploy the AppDynamics Operator on Red Hat OpenShift)

This page contains links to Kubernetes documentation. AppDynamics makes no representation as to the accuracy of Kubernetes documentation because Kubernetes controls its own documentation.

1. Ensure your kubectl is pointing to your Kubernetes cluster. See Install and Set Up kubectl in the Kubernetes documentation

2. Log on as a cluster administrator.

3. To create a namespace for appdynamics in your Kubernetes cluster, enter:

   $ kubectl create namespace appdynamics

   CODE

4. To verify your namespace is created, enter:

   $ kubectl get namespace

   CODE

   Example output:

   NAME				STATUS			AGE
   appdynamics			Active			5s
   default				Active			41d
   kube-node-lease		Active			41d
   kube-public			Active			41d
   kube-system			Active			41d

   TEXT

5. To install the latest version of the AppDynamics Operator for Kubernetes, enter:

   $ kubectl create -f cluster-agent-operator.yaml

   CODE

   For Kubernetes version that is less than or equal to 1.14, enter the following command:

   kubectl create -f cluster-agent-operator-1.14-or-less.yaml

   CODE

   The AppDynamics Operator creates a Custom Resource Definition, which extends the Kubernetes APIs to create a new Kubernetes type called clusteragents. The AppDynamics Operator also creates a serviceaccount, a clusterrole, and clusterrolebinding for the namespace.

   Example output: 

   customresourcedefinition.apiextensions.k8s.io/clusteragents.appdynamics.com created
   customresourcedefinition.apiextensions.k8s.io/infravizs.appdynamics.com created
   serviceaccount/appdynamics-operator created
   serviceaccount/appdynamics-infraviz created
   podsecuritypolicy.extensions/appdynamics-infraviz created
   clusterrole.rbac.authorization.k8s.io/appdynamics-operator created
   clusterrolebinding.rbac.authorization.k8s.io/appdynamics-operator created
   clusterrolebinding.rbac.authorization.k8s.io/appdynamics-infraviz created
   role.rbac.authorization.k8s.io/appdynamics-infraviz created
   rolebinding.rbac.authorization.k8s.io/appdynamics-infraviz created
   deployment.apps/appdynamics-operator created

   CODE

6. To verify that the AppDynamics Operator is running, enter:

   kubectl -n appdynamics get pods

   CODE

   Example output:

   NAME									READY		STATUS		RESTARTS	AGE
   appdynamics-operator-95ffb549c-m8tjv	1/1			Running		0			30s

   CODE

   This output shows that Kubernetes extends the custom resource definitions that you provided. You can now Build the Cluster Agent Container Image.
