deploying

Deploy confluent-for-kubernetes deployment using the operator

./create-kafka-deployment.sh <namespace> <Domain-url> <config-template.yaml> <kafka-user> <kafka-user-pass> <c3-user> <c3-user-pass>

e.g.

./create-kafka-deployment.sh confluent apps.ns.cp.fyre.ibm.com kafka-template.yaml kuser kuserPASS c3user c3userPASS

Before running this script make sure you edit the create-kafka-certs.sh and make sure line# 3 and 4 is to your liking.

This script creates the namespace, and installs the operator within the namespace. It then generates all the certificates for the components, creates the secrets and generates the deployment configuration. Apply the deployment using

oc apply -f deployed-config-template.yaml

deploying a specific version of the operator

The create-kafka-deployment script deploys the latest version of the helm chart available in the repo. However, if there is a need to install a specific version of the chart after adding the repo, you can install a specific version of the release.

Adding the repo by issuing the following command

helm repo add confluentinc https://packages.confluent.io/helm

Now you can list the available versions by running

helm search repo confluentinc -l

Then picking a specific version to install by issuing

helm upgrade --install cfk-operator confluentinc/confluent-for-kubernetes --version 0.304.17

remember it is Chart Version you are installing and not the App Version

licensed version

Before running the oc apply command update your operator with your license text.

helm upgrade --install cfk-operator confluentinc/confluent-for-kubernetes --set licenseKey=<CFK license key>

After the operator is updated, you can edit all the components in the yaml and add

spec:
  license:
    globalLicense: true

and re-apply the deployment.

cat deployed-kafka-template.yaml | yq e ".spec.license.globalLicense=true" - | oc apply -f -

if you want to keep a copy of the deployment yaml. Just pipe it into a file and save it

cat deployed-kafka-template.yaml | yq e ".spec.license.globalLicense=true" - > deployed-kafka-template-lic.yaml

oc apply -f deployed-kafka-template-lic.yaml

removing

./remove-kafka-deployment.sh <namespace>

e.g.

./remove-kafka-deployment.sh confluent

This script deletes the current deployment from the namespace and deletes the secrets generated by the deployment. It doesn't remove the namespace. You can remove it by

oc delete project <namespace>
