Deploy Data Collector in native Kubernetes environment

This procedure provides the steps to deploy Data Collector Docker image on a Kubernetes cluster through an operator with the required configuration on Linux hosts. This method enables efficient Data Collector installation and reduces the human errors caused during manual or ISO-based installations.

Prerequisites and dependencies

System requirements and installation dependencies for the system on which Data Collector will be installed are listed below:

Obtain the Docker image generated from the CI/CD build.
Kubernetes must be pre-installed on the system.
Assume root role on the host system.
Kubernetes cluster must be accessible on the system.
Ensure that the file system supporting the /data directory has enough free space as recommended in the NetBackup IT Analytics Certified Configurations Guide for Data Collector.
The /data directory in the host system will be mounted inside the container as /usr/openv/analyticscollector.
Obtain the following Data Collector details. You are required to supply these details to the installer during the installation process.
- Registry: The name of the registry to which you want to push the installer images.
- Absolute path of Data Receiver Certificate file: Absolute path of the data receiver certificate file downloaded from NetBackup IT Analytics Portal.
- Absolute path of the Data Collector Registration File: Absolute path of the Data Collector registration file downloaded from the NetBackup IT Analytics Portal.
- Proxy settings:
- Portal IP address: IP address of the system hosting the NetBackup IT Analytics Portal.
- Portal HostName: aptareportal.<DOMAIN> or itanalyticsportal.<DOMAIN>
- Agent HostName: aptareagent.<DOMAIN> or  itanalyticsagent.<DOMAIN>
- StorageClass Name: Name of the Kubernetes storage class to be used.
Obtain the itanalytics_k8s_artificats.tar from the Cohesity Download Center. The tarball has the container image, operater image, set of .yaml files, and the scripts.

Deploy the Data Collector in Kubernetes environment

To deploy the Data Collector in Kubernetes environment:

Login to the Kubernetes cluster.
Run this command on the primary node and label the node on which you want to deploy the Data Collector.
```
kubectl label node <worker_node_name> itaDcNodeKey=itaDcDeploymentNode
```
From the itanalytics_k8s_artifacts.tar location, run this command to initiate the Data Collector installation.
```
tar -xvf itanalytics_k8s_artifacts.tar scripts 
```
This saves a scripts folder at the itanalytics_k8s_artifacts.tar file location,.
From the scripts folder, run this script.
```
cd scripts/
sh itanalytics_dc_installer.sh
```
Note:
The installation logs are saved to itanalytics_dc_installer_<time_stamp>.log.
Provide the Data Collector configuration details when asked by the installer in the following order.
- Registry
  The installer asks for a confirmation after providing the registry name to proceed with pushing the images. You need to enter y for a fresh installation. If for any reason, you are required to re-run the installation and this step was successfully completed anytime before for the same cluster node, you can enter n to avoid a rewrite and bypass this step.
- Absolute path of Data Receiver Certificate file (if you have set an https:// URL for the data receiver)
- Absolute path of the Data Collector registration file
- Proxy settings
- Portal IP address
- Portal HostName
- Agent HostName
- StorageClass Name
The installer asks to confirm the configuration details before proceeding with the installation. Enter y to proceed with the data collector installation

After a successful installation, verify whether the Data Collector status appears Online on the NetBackup IT Analytics Portal.

Connect to the pod instance

Run this command to connect to the pod instance and also to facilitate debugging when required.

# kubectl exec -it<pod ID> -- bash
