Deploying Plone on AWS
0 likes483 views
This document discusses deploying Plone on Amazon Web Services (AWS) using automation tools like Ansible and Terraform. It describes setting up a basic Plone stack with nginx, ZEO clients and servers. Manual deployment is error-prone, so the document recommends using configuration management tools to deploy Plone servers repeatably. It demonstrates deploying a Plone server to AWS using Terraform to provision servers and Saltstack to configure the software.
Deploying Plone on AWS
- 1. DEPLOYING PLONE ON AMAZON AWS Kim Nguyen / kim@sixfeetup.com
- 2. ABOUT ME ➤ Working with Plone since 2003 ➤ 350+ Plone sites at University of Wisconsin Oshkosh ➤ Developer → team lead → project manager ➤ Engineering team lead @ Six Feet Up
- 3. PLONE It's hardcore It can scale
- 5. BASIC PLONE STACK ➤ nginx web server ➤ (optional) varnish cache ➤ 2+ ZEO clients ➤ 1 ZEO server
- 7. MANUAL DEPLOYMENT ➤ Provision a virtual machine (Digital Ocean, Linode, Amazon Lightsail) ➤ Set up firewall ➤ Download and run the Plone unified installer ➤ Set up nginx web server ➤ Set up automatic Plone start scripts ➤ Set up cron jobs (zeopack, backup) ➤ Remember to log in periodically to apply system updates ➤ Hope no one hacks into the system (no monitoring)
- 8. THERE IS A BETTER WAY
- 9. THE BETTER WAY ➤ Deploy repeatably, consistently ➤ Keep server configuration under version control ➤ Make all configuration changes in one place ➤ Use automation to deploy configuration changes ➤ Avoid logging into the servers ➤ NEVER MODIFY THE SERVERS DIRECTLY
- 10. WHY USE REPEATABLE DEPLOYMENTS ➤ There is never any question about what’s running on a given server ➤ Consistency of configuration → when you make a change in one Plone server, it is made on all Plone servers ➤ With repeatable deployments you can easily create multiple environments for: ➤ testing ➤ Quality Assurance or staging ➤ production ➤ disaster recovery
- 12. TOOLS FOR REPEATABLE DEPLOYMENTS ➤ Ansible (ansible.com) ➤ Terraform (terraform.io) ➤ Saltstack (saltstack.com)
- 14. PLONE ANSIBLE PLAYBOOK ➤ Use Ansible to provision a single full-stack Plone server github.com/plone/ansible- playbook with ➤ a Plone ZEO cluster (1 ZEO server, 2 ZEO clients) ➤ supervisor for automatic start/stop of the Plone cluster ➤ HAProxy load balancing ➤ Varnish caching ➤ Nginx as a proxy and URL rewrite engine ➤ Postfix for outgoing mail ➤ munin-node, logwatch and fail2ban for monitoring and log analysis ➤ Vagrant and VirtualBox for testing the setup
- 15. BUT THAT’S JUST ONE SERVER
- 16. DEPLOY TO THE CLOUD
- 17. ➤ For this demo, we will use Amazon AWS ➤ Biggest established cloud provider ➤ Continuing adoption growth ➤ Robust, well understood ➤ Many other services available (e.g. machine learning, containers, databases) ➤ 66 availability zones in 21 geographic regions DEPLOY TO THE CLOUD
- 18. DEMO: TERRAFORM ➤ Demo code: github.com/tkimnguyen/aws-auto-deploy-demo ➤ Terraform will provision servers using AWS: ➤ Create virtual private cloud (VPC) ➤ Define access control lists (ACLs) ➤ Create 2 Elastic Compute Cloud (EC2) instances ➤ A salt “master” ➤ A salt “minion” (the Plone server)
- 19. DEMO: SALT ➤ Then Terraform invokes Saltstack on the minion to set up our software ➤ Saltstack reads states stored on the master to: ➤ Install Plone ➤ Install and configure supervisor
- 20. AWS PREPARATION ➤ Create an AWS account at aws.amazon.com ➤ Create an AWS user at console.aws.amazon.com/iam ➤ Set up an access key pair called plone-conf-demo-sfup by importing your ssh public key ➤ Add aws_access_key_id and aws_secret_access_key to your ~/.aws/ credentials file
- 21. LOCAL COMPUTER PREPARATION ➤ Install Terraform from www.terraform.io/downloads.html git clone https://github.com/tkimnguyen/aws-auto-deploy- demo.git cd aws-auto-deploy-demo cd terraform terraform init terraform plan
- 22. DEMO STEPS ➤ Apply the Terraform plan terraform apply ➤ Obtain IP address of Plone server terraform state pull aws_instance |egrep ‘"name"|public_ip"' ➤ ssh into Plone server ssh -L8080:localhost:8080 ubuntu@18.209.237.90 ➤ view salt progress log tail -f /var/log/cloud-init-output.log
- 24. OTHER AWS GOODIES ➤ CloudFront (aws.amazon.com/cloudfront) for content delivery network (caching) around the world ➤ Shield for DDoS mitigation, Web Application Firewall ➤ CloudWatch (aws.amazon.com/cloudwatch) for monitoring and autoscaling ➤ Elastic Load Balancing (aws.amazon.com/elasticloadbalancing) for load balancing of HTTP and HTTPS traffic, integration with Auto Scaling, monitoring & auditing ➤ Relational Database Service (aws.amazon.com/rds) with PostgreSQL → use with Plone RelStorage → now you have replication and failover
