Deploy IBM Sterling Order Manager Software on OpenShift — Part 2
Read the previous article
For this article, I am going to walk through simple setup of DB2 running on Openshift which is required for IBM Sterling Order Manager Software.
Important Step:
Follow this step in DB2 project so the images are pulled successfully and deployed into OpenShift Cluster.
(1) Obtaining your entitlement key
- Go to the Container software library.
- Click Copy key.
- Copy the entitlement key to a safe place so you can use it when you add the pull secret in the next section.
(2) ibm-registry secret
Create the secret with entitlement key which you received from above steps
(3) Add the secret “ibm-registry” to the ServiceAccount:imagePullSecret which will be used to Deploy DB2 on the OpenShift
Note: Repeat steps (2) and (3) for the new Secret called “ibm-entitlement” which is required sometimes for DB2
Deploy the IBM DB2 on the OpenShift Cluster
To enable the IBM Operator Catalog in your OpenShift cluster:
- From your OpenShift UI console, select Import YAML. Paste the following YAML and Click Import
apiVersion: operators.coreos.com/v1alpha1 kind: CatalogSource metadata: name: ibm-operator-catalog namespace: openshift-marketplace spec: displayName: “IBM Operator Catalog” publisher: IBM sourceType: grpc image: icr.io/cpopen/ibm-operator-catalog updateStrategy: registryPoll: interval: 45m
As a result, you will see DB2 Operator in the OperatorHub
Select the DB2 Operator and Click Install which will ask you project/namespace to be installed.
As result, you will see operator got installed successfully in the selected project.
Next step is to create the db2 instance-cluster. Depending on the Storage (OCS or Portworx), you need to modify the storage classes in the YAML and create the instances
OpenShift Container Storage Class YAML
StorageClass :
Portworx Storage Class YAML
StorageClass:
- portworx-db2-rwo-sc
- portworx-db2-rwx-sc
As a result of creating db2 instances, you will be seeing following outcome
DB2 Pods
DB2 Services
Persistent Volume Claim
Verification
- Login to Red Hat OpenShift Console and switch to “Developer” view on the top left hand corner.
- Click Topology which will display DB2 applications running on installed namespace
Verify the DB2 is running
Go to pod related to db2ucluster-XXX and open terminal
su — db2inst1
db2 list db directory
db2 connect to OMDB
Congrats !! DB2 is successfully deployed on OpenShift Cluster.
Special thanks to Robert Borovsky for helping.
