Drupaljam 2017 - Deploying Drupal 8 onto Hosted Kubernetes in Google Cloud
4 likes3,553 views
In this presentation I explain using video examples how kubernetes works and how this can be used to host your Drupal 7 or 8 site. There are obviously also gotcha's and I'd like to warn you to not use this in production until you've verified it

Drupaljam 2017 - Deploying Drupal 8 onto Hosted Kubernetes in Google Cloud
- 1. Drupal 8 on Kubernetes using Google Cloud ship-shipping ship, shipping shipping ships
- 2. 2 Drupal 8 on Kubernetes using Google Cloud Nick Veenhof A lot of credit goes to @tpryan to give all these awesome sessions regarding kubernetes. Please thank him instead of me :)
- 4. 4 What is our goal?
- 5. 5 Deploying Drupal 8 in a scalable manner, preferring code over infrastructure
- 8. 8 • Create a server • Linux • Apache • PHP • MySQL • Get starting schema and content on it • Initialize system Fairly Default Process
- 9. 9 # Request Machine gcloud compute instances create $(MYSQL_HOSTNAME) --zone $(ZONE) --machine-type "f1-micro" --image-family="debian-8" --image-project="debian-cloud" --tags "http-server","https-server" # Install Apache + PHP apt-get update -y apt-get install apache2 php5 curl php5-curl -y # Install MySQL and PHP libratries DEBIAN_FRONTEND=noninteractive apt-get -y install mysql-server mysql-client php5-mysqlnd php-pear -y /etc/init.d/apache2 restart … Create a server
- 10. 10 3-Tier version of LAMP Stack
- 11. 11 • Create an Apache Server • Create a Mysql Server • Create a filesystem server (NFS/…) • Get starting schema on Mysql Server • Get Git repo on Apache server and link sites/default/files to file server • Get files on file server Somewhat Default Process
- 13. 13 Containerized
- 14. FROM php:7.0-apache RUN apt-get update && apt-get install -y php5-mysqlnd RUN docker-php-ext-install mysqli RUN a2enmod rewrite && a2enmod headers && service apache2 restart COPY app/ /var/www/html/ EXPOSE 80 FROM ubuntu:xenial RUN apt-get update && apt-get install -y —no-install- recommends netbase nfs-kernel-server && rm -rf /var/lib/apt/ lists/* RUN mkdir -p /exports VOLUME /exports FROM mysql/mysql-server:5.6 ADD sql/load.sql /docker-entrypoint-initdb.d/load.sql EXPOSE 3306 14
- 15. docker run --name=3tier_drupal --link 3tier_db:mysql --link 3tier_nfs:nfs -d -p 80:80 3tier_drupal docker run --name=3tier_nfs -d -p 2049:2049 3tier_frontend docker run --name=3tier_db -d -p 3306:3306 3tier_db 15 Startup Scripts

- 22. 22 That’s a lot to manage…
- 23. 23 Kubernetes Container Orchestration System Open Source Started by Google Contributed to by others Google offers hosted kubernetes
- 24. 24 DB - Google Cloud Managed SQL NFS Server - gcr.io/google_containers/volume-nfs:0.8 Apache - wodby/php container images
- 25. 25 Demo of the interface
- 27. 27 Setting up the NFS server
- 28. 28 Services A Kubernetes Service is an abstraction which defines a logical set of Pods and a policy by which to access them - sometimes called a micro-service.
- 29. 29 kind: Service apiVersion: v1 metadata: name: nfs-shared1-server spec: ports: - name: nfs port: 2049 - name: mountd port: 20048 - name: rpcbind port: 111 selector: role: nfs-shared1-server
- 31. 31 apiVersion: v1 kind: PersistentVolumeClaim metadata: name: nfs-shared1-200gb annotations: volume.alpha.kubernetes.io/storage-class: standard spec: accessModes: [ "ReadWriteOnce" ] resources: requests: storage: 200Gi
- 32. 32 ReplicationController A ReplicationController ensures that a specified number of pod “replicas” are running at any one time.
- 33. 33 apiVersion: v1 kind: ReplicationController metadata: name: nfs-shared1-server spec: replicas: 1 selector: role: nfs-shared1-server template: metadata: labels: role: nfs-shared1-server spec: containers: - name: nfs-shared1-server image: gcr.io/google_containers/volume-nfs:0.8 resources: limits: cpu: 0.01 ports: - name: nfs
- 34. 34 Setting up the Lamp stack
- 35. 35 Services
- 36. 36 apiVersion: v1 kind: Service metadata: name: nickveenhofbe labels: site: nickveenhofbe spec: type: LoadBalancer ports: - name: http port: 80 targetPort: 80 protocol: TCP - name: https port: 443 targetPort: 80 protocol: TCP selector: service: nickveenhofbe
- 37. 37 PersistentVolume A PersistentVolume (PV) is a piece of networked storage in the cluster that has been provisioned by an administrator.
- 38. 38 apiVersion: v1 kind: PersistentVolume metadata: name: nvbenfs labels: site: nickveenhofbe spec: capacity: storage: 10Gi accessModes: - ReadWriteMany nfs: # FIXME: use the right IP server: 10.3.247.140 path: "/nickveenhofbe"
- 40. 40 kind: PersistentVolumeClaim apiVersion: v1 metadata: name: nvbenfs labels: site: nickveenhofbe spec: accessModes: - ReadWriteMany resources: requests: storage: 10Gi
- 41. 41 Pods/Deployment A pod (as in a pod of whales or pea pod) is a group of one or more containers (such as Docker containers), the shared storage for those containers, and options about how to run the containers. A Deployment provides declarative updates for Pods and ReplicaSets (the next- generation ReplicationController).

- 44. 44 A Little Slower? Let’s take a look at that code https://github.com/nickveenhof/drupal-docker-with-volume/blob/master/gcloud_instructions/nickveenhofbe/ pods.yaml
- 45. 45 How do we deploy this? Let’s take a look!
- 47. 47 Conclusion?
- 48. 48 Industrialisation of hosting services is happening
- 49. 49 All in one boxes are a liability
- 51. 51 1. Servers are a commodity. 2. Managing services is a commodity 3. Do not make the mistake thinking you know better. Caveat: For Drupal, the one massive pain holding us back from going all in with Google Cloud is not having a managed distributed file system like Amazon EFS.
