Steps

0. Clone the repository

git clone https://github.com/prb112/openshift-demo.git

1. Install kustomize

$ brew install kustomize

2. Login to your cluster using oc.

3. Generate a randomized password

$ ENV_PASS=$(openssl rand -hex 10)
$ echo ${ENV_PASS}

Note, save the output…

4. Generate the working url for the cluster/ghost app.

$ export WEB_DOMAIN=https://web-route-ghost.apps.$(oc get ingress.config.openshift.io cluster -o yaml | grep domain | awk '{print $NF}')
$ echo ${WEB_DOMAIN}

5. Change to the ghost/deploy directory using cd openshift-demo/ghost/deploy

6. Create the secret for the database

$ cat secrets/01_db_secret.yml | sed "s|ENV_PASS|${ENV_PASS}|" | oc apply -f -

7. Create the configmap for the Ghost app URL.

$ cat secrets/02_web_cm.yml | sed "s|WEB_DOMAIN|${WEB_DOMAIN}|" | oc apply -f -

8. Create the deployment for the website

$ oc apply -k overlays/dev
namespace/ghost configured
service/db-service unchanged
service/web unchanged
persistentvolumeclaim/db-pvc unchanged
persistentvolumeclaim/web-content unchanged
deployment.apps/ghost-db unchanged
deployment.apps/web unchanged
route.route.openshift.io/web-route unchanged

9. To clean it up you can run…

$ oc delete -k overlays/dev
namespace "ghost" deleted
service "db-service" deleted
service "web" deleted
persistentvolumeclaim "db-pvc" deleted
persistentvolumeclaim "web-content" deleted
deployment.apps "ghost-db" deleted
deployment.apps "web" deleted
route.route.openshift.io "web-route" deleted

10. To see your website URL, you can grab the config map.

$ oc get cm -o yaml

10. Navigate to the URL, such as https://web-route-ghost.apps.xyz.zzz.zyz.com/ghost/ to start setting up your site.

Note, if I had time, I would have generated a non-privileged user for MySQL and used that on the MySQL instance.
