OKD agent installation in Custom Namespace

Step 1: Configure the namespace

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

   oc create ns {namespace-name} 
         

   For example- oc create ns monitoring

Step 2: Install the integration

1. From All Clients, select a client.

2. Go to Setup > Integrations and Apps.

3. If there are apps/integrations already installed, it will redirect to the INSTALLED INTEGRATIONS page where all the installed integrations/apps are displayed. Click +ADD and search for OKD on the AVAILABLE INTEGRATIONS AND APPS page. Also you can use the All Categories dropdown list to search. If there are no installed apps, it will navigate to the AVAILABLE INTEGRATIONS AND APPS page.

4. Click +ADD on the OKD tile.

5. Enter the following details:

   • Name: Name for the integration.
   • Deployment type: On-prem or Cloud (AWS, GKE, and AKS)
   • Container Engine: Docker or ContainerD. Primarily, Docker is used. ContainerD is used for K3s integration.
     
     

6. Click on NEXT.

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:

   oc 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.

   oc 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
