Ghost deployment manual

We are deploying Ghost using the bitnami/ghost Helm chart.

Note that we currently do not have a storage class for provisioning PVs. The setup described below requires a manual creation and binding of PVCs. This setup will most probably change.

Prerequisites:

• Have a storage class rook-ceph-block configured.

The settings for the Helm chart can be found in ghost.values.yaml.

Updating Ghost settings once it is already deployed

Changing the values of the Helm chart will not update the settings for an already configured Ghost instance. To do that a different approach is required.

1. Copy the config.production.json file from the running container to your local machine. For example:

kubectl cp ghost/ghost-597d75fbf-p7qwr:/bitnami/ghost/config.production.json config.production.json

2. Edit the file as you wish.
3. Copy the file back into the running container. For example:

kubectl cp config.production.json ghost/ghost-597d75fbf-p7qwr:/bitnami/ghost/config.production.json

4. Scale down the deployment of ghost to 0.

kubectl scale -n ghost deployment ghost --replicas=0

5. Scale the deployment of ghost to 1 again.

kubectl scale -n ghost deployment ghost --replicas=1
