Quickstart Install

These instructions are for ghost installation on bare metal Kubernetes cluster using helm.

  • Run the update dependency command to create bitnami MySQL helm chart in the ghost helm charts directory
git clone https://github.com/Muneer94/ghost-deploy.git
cd ghost-deploy
helm dependency update ./ghost --debug
Enter fullscreen mode Exit fullscreen mode
  • Deploy local-path-provisioner storage class but it does not support readwritemany so for high availability of your Kubernetes cluster better to use longhorn
# mak sure following packages are installed in kubernetes nodes
sudo apt-get install nfs-common cifs-utils -y
# longhorn
helm repo add longhorn https://charts.longhorn.io
helm repo update
helm upgrade --install longhorn longhorn/longhorn --namespace longhorn-system --create-namespace
# make longhorn storage class as false so that we won't have multiple storage classes as default
kubectl patch storageclass longhorn -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
Enter fullscreen mode Exit fullscreen mode
  • Deploy ghost
helm upgrade --install ghost ghost --namespace example --create-namespace -f custom/ghost/example.yaml
Enter fullscreen mode Exit fullscreen mode
  • Deploy ingress nginx controller to access ghost publicly with custom values in custom/ghost directory
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm upgrade --install ingress-nginx ingress-nginx/ingress-nginx --namespace ingress-nginx --create-namespace -f custom/ghost/nginx.yaml
Enter fullscreen mode Exit fullscreen mode
  • Create ingress rules for routing traffic to ghost pod
kubectl apply -f custom/ghost/ingress.yaml -n example
Enter fullscreen mode Exit fullscreen mode

Deploying self hosted ghost on kubernetes with multiple replicas is not supported yet, we will be deploying it with only 1 replica.
