Moodle Google - Run Moodle on Google Cloud Kubernetes Engine

Requirements

1. terraform 1.2.8+
2. kubectl 1.22+
3. gcloud cli
4. Google Cloud Account access
5. Enable Google APIs (gcloud services enable):
   • artifactregistry.googleapis.com
   • compute.googleapis.com
   • container.googleapis.com
   • servicenetworking.googleapis.com
   • file.googleapis.com
   • sqladmin.googleapis.com

How to deploy this project

Build the image from this repository Push to Artifact Registry and pass image_name and image_tag to Terraform variable, then:

terraform init
terraform plan
terraform apply

Initialize kubectl access with:

gcloud container clusters get-credentials gke-moodle-tf --region us-central1

After that, deploy kubernetes application using:

kubectl create namespace moodle
kubectl apply -k manifests/overlays/development

Reset admin password:

kubectl -n moodle get pods      # select one of the pods "moodle-xxx"
kubectl -n moodle exec -ti (pod_name) -c php-fpm -- \
	php /var/www/html/admin/cli/reset_password.php \
	--username=admin \
	--password=(new_password) \
	--ignore-password-policy

From terraform output, open http://${loadbalancer_ip_address}, login with credentials admin:new_password (Provisioning of Load Balancer can take up to 10 minutes)

Tuning server configuration

You can modify contents of manifests/overlays/development/serverconfig to your requirements, if you like, however, default values are recommended.

• default.conf: nginx server block configuration.
• php.ini: default configuration for PHP.
• www.conf: default pool directives for PHP-FPM.

Please consider config.php file will be overwritten after terraform apply. It is better to modify this file AFTER terraform apply. To apply changes, run kubectl apply -k manifests/overlays/development again.

Cleanup

Run kubectl delete namespace moodle then terraform destroy.
