Creates a bunch of pages in SilverStripe for testing. It'll take a long time to run, but good for testing how your site performs with a huge amount of pages. Put it into your `mysite/tasks` directory, then invoke the script by running `sake dev/tasks/GeneratePagesTask flush=1`

	<?php
	class GeneratePagesTask extends BuildTask {

	public function run($request) {
	for($i = 1; $i < 10; $i++) {
	$segment = sprintf('page-top-level-%d', $i);
	$p1 = SiteTree::get_by_link($segment);
	if(!($p1 && $p1->exists())) {
	echo "Creating page $i...";

halkyon / ghost-blog-kubernetes.yaml

Last active July 15, 2020 00:53

Kubernetes YAML (namespace, service, ingress, deployment) for running a very simple setup of Ghost (https://github.com/TryGhost/Ghost)

	# Simple setup of Ghost in Kubernetes.
	#
	# Some points to consider:
	# - Content is stored in a single persistent disk, and database is SQLite. Using a dedicated database would be ideal
	# for bigger deployments, and using distributed storage would allow pods to horizontally scale, e.g. GlusterFS, EFS.
	#
	# - A load balancer is provisioned for external traffic to access the blog service. For a multi-tenanted approach,
	# nginx ingress controller (https://kubernetes.github.io/ingress-nginx/deploy/) could be used.
	#
	# - No TLS for the service. This could be accomplished using GCP, or AWS managed certs on the load balancer.
