  • Installing Watson AIOps AI-Manager on ROKS

The article is based on the the following.

  • RedHat OpenShift 4.8 on IBM Cloud (ROKS)
  • Watson AIOps 3.2.0

1. Watson AIOps 3.2.0 installation and demo setup requirements.

This documentation explains about the Hardware and account requirements for Watson AIOps 3.2.0 installation and demo setup.

1. RedHat Openshift on IBM Cloud

A RedHat Openshift on IBM Cloud (ROKS) with the below configuration needed to install Watson AIOps 3.2

  • OCP Version : 4.8.18
  • 5 Nodes with b3c.16x64 flavour. (CPU 16 core, Memory 64 GB)
  • Classic Infrastructure

2. IKS Cluster on IBM Cloud

A IBM Cloud Kubernetes Service, cluster on IBM cloud is needed to install iLender application (a sample application). This is required for WAIOps demo setup.

  • Kubernetes Version : 1.19.15_1565
  • 1 Node with b3c.8x32 flavour. (CPU 8 core, Memory 32 GB)
  • Classic Infrastructure

3. Humio VM

A VM with the below configuration is needed for Humio Logging System installation as part of the WAIOps demo setup. 

  • OS : CentOS Linux 8
  • CPU : 16 Core
  • Memory : 64 GB
This can also be installed in Openshift cluster as well.

4. Slack Account

SRE would be indicated about the incident through ChatOps such as Slack or Team.

Slack account is required for the WAIOps demo setup.

The link here explains about account creation and integration with WAIOps.

5. ServiceNow Account

A ServiceNow account is required or atleast Developer instance to be created using the below URL as part of the WAIOps demo setup..

https://developer.servicenow.com/dev.do#!/guides/paris/developer-program/pdi-guide/obtaining-a-pdi

Watson AIOps can create Incidents in ServiceNow apart from slack story. Also it can train the existing incidents from ServiceNow for identifying the Similar Incidents and to choose the next best action, in case of an incident.

Pre-requisite

Global Pull Secret to be updated in Openshift before installing WAIOps 3.2.0. This is discussed in the above section.

1. Create Project, entitlement key secret and catalog source

In this section we create the following.

  • Create a custom project called cp4waiops
  • Create an Operator group called cp4waiops-operator-group in your custom project cp4waiops
  • Create the entitlement key pull secret called ibm-entitlement-key
  • Create the catalog source called ibm-operator-catalog

Do the following.

  1. Get IBM entitlement key from https://myibm.ibm.com/products-services/containerlibrary
  2. Replace the value of the ENTITLEMENT_KEY variable in files/01-project-secret-catalog-source.sh
  3. Run the command sh files/01-project-secret-catalog-source.sh

2. Install AI-Manager operator

In this section, we install the AI-Manager operator by creating the subscription called ibm-aiops-orchestrator .

Do the following.

  1. Run the command sh files/02-ai-manager-operator.sh

3. Verify AI-Manager operator install completed

In this section, we verify the AI-Manager operator install is completed or not.

In this section, we install the AI-Manager by creating the Installation called ibm-cp-watson-aiops .

Do the following.

  1. Run the command sh files/04-ai-manager.sh

Note that we use ibmc-file-gold-gid storage class here.

  storageClass: ibmc-file-gold-gid
  storageClassLargeBlock: ibmc-file-gold-gid

5. Verify AI-Manager install completed

In this section, we verify the AI-Manager install is completed or not.

Do the following.

  1. Run the command sh files/05-verify-ai-manager.sh
  2. It should print the output like this.
NAME                  PHASE     LICENSE    STORAGECLASS         STORAGECLASSLARGEBLOCK   AGE
