Redhat Openshift Kubernetes

Specific item for running mPower on Openshift.

Main topic - do not use Ingress-Controller (via Dependencies setup) but to use Openshift Routes

Steps

1. Login to OpenShift:

    oc login api.ocptest.ist.sn:6443 -u kubeadmin -p …  

2. Create a new project(namespace) for mPower:

    oc new-project mpower --display-name="Kobil mPower" --description=" Kobil mPower Eco System"  

3. Create service account for mpower-ssms charts to use required privileged.

    oc create serviceaccount mpower-ssms-sa  

4. Add anyuid and privileged scc's to default and mpower-ssms service accounts

    oc adm policy add-scc-to-user anyuid -z mpower-ssms-sa  
   
    oc adm policy add-scc-to-user privileged -z mpower-ssms-sa  

5. Create a docker registry secret(mpower-registry-pull) to pull images from Kobil Docker Hub

    oc create secret docker-registry mpower-registry-pull --docker-server=https://index.docker.io/v1/ --docker-username=... --docker-password=...  

6. Add Kobil chart repo to download Kobil helm charts

    helm repo add kobil https://charts.kobil.com --username ... --password ...  
   
    helm repo update  
   
    helm search repo kobil  
   
    helm pull kobil/mpower  

7. Install mPower

8. Install helm chart with the customized values.yaml file. So, edit your previously created image pull secret, disable all other entries and enter the admin user and password for the SSMS server.

9. Consider storage-class which is used by OpenShift cluster and edit if needed.

10. Consider namespace

11. Set the DB username and password to allow access for the SSMS server to the DB.

12. Disable all the other components that are not required for running only the SSMS server.
