# Set up a managed mysql instance and import a database into it. Next, copy the nickveenhofbe folder and modify the information in pods.yaml to match your setup.

# Create NFS Server PV & Claim
kubectl create -f nfs-shared1-pv.yaml

# Create NFS Server
kubectl create -f nfs-shared1-server.yaml

# Create a folder for your site
kubectl exec -it nfs-shared1-server-rxlfk mkdir /exports/nickveenhofbe

# Create NFS Service
kubectl create -f nfs-shared1-service.yaml

# Get the IP Address for our NFS Shared1 server
kubectl describe service nfs-shared1-server

# Replace IP address in nickveenhofbe/nfs-pv.yaml
# And Create NFS folder volume to mount for our site
kubectl create -f nickveenhofbe/nfs-pv.yaml

# Claim this NFS folder volume
kubectl create -f nickveenhofbe/nfs-pv-claim.yaml

# Start the pods (2 of them)
kubectl create -f nickveenhofbe/pods.yaml

# Update the Drupal pod
kubectl replace -f nickveenhofbe/pods.yaml

# Create drupal service
kubectl create -f nickveenhofbe/lb.yaml

# verify that it points to defined endpoints (eg, ip's)
kubectl describe service nickveenhofbe

# Get our properties in order to visit our site. Wait till it mentions a property like: "LoadBalancer Ingress". It might take a while before the load balancer is created.
kubectl describe service nickveenhofbe

# Visit the site on the Public IP that is found in the load balancer
# and behold the beauty of your own HA site.

# Caveats & TODOs
# It does not properly use the NFS voluem yet to share files for sites/default/files so file uploads will only be seen in 1 of the 2 pods.
