Kubernetes agent installation in Custom Namespace

Step 1: Configure the namespace

1. Connect to a cluster and create a custom namespace.

   kubectl create ns {namespace-name} 
         

   For example- kubectl create ns monitoring

Step 2: Install the integration in the OpsRamp

1. Go to Setup > Integrations and Apps.

   

2. Click on +Add button.
3. Now use the search to search the kubernetes app.
4. Click on ADD to add the kubernetes app.
5. On the next screen, click Install.
6. In the kubernetes Integration page, enter the following details:

   

   • Name: Name of the Integration.
   • Deployment: Select the deployment from the dropdown.
   • Container Engine: Select the container type from the list.
7. After installing, you will get the below page. Click on Copy content.

   

Step 3: Configure the integration

1. Create a YAML file in the cluster. Example- agent.yaml

2. Paste the copied content from the portal into a new YAML file.

3. Now, replace the namespace: OpsRamp-agent to the created new namespace.

4. Remove the section for creating namespace in the OpsRamp Agent YAML.

   apiVersion: v1
   kind: Namespace
   metadata:
     name: opsramp-agent

   Note: You must change the namespace to custom namespace (ex- monitoring) wherever namespace exists in the file and then save the file.

   

   Example: Follow the similar ways and change the namespace as given a example for ServiceAccount namespace below:
   • ServiceAccount
   • ClusterRoleBinding
   • DaemonSet
   • Deployment
   • ConfigMap in OpsRamp Agent YAML

5. Run the below command to apply the configuration:

   kubectl apply -f agent.yaml

6. Now the agent is installed in your cluster.

7. To check the status of the agent installed in the namespace, run the command below.

   kubectl get pods -n monitoring

Step 4: Check the status of namespace in OpsRmap

3. Go to OpsRamp portal, click on Infrastructure > Resources.
4. In the lift side of the page, click on kubernetes to expand it.
5. Next, expand the nodes and then click on container.
6. Then, under Attributes, you can view the status of your newly created namespace.

   

OpsRamp Agent yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: opsrampagent
  namespace: opsramp-agent
automountServiceAccountToken: true

    apiVersion: v1
    kind: ServiceAccount
    metadata:
     name: opsrampagent
     namespace: monitoring
    automountServiceAccountToken: true
