4. Crunchy PostgreSQL for Kubernetes
● Group of open source projects to combine the robustness of PostgreSQL
with the deployment flexibility of Kubernetes
○ Crunchy Container Suite
○ Crunchy PostgreSQL Operator
● Works on enterprise Kubernetes based platforms
● Actively developed
● Successfully deployed at Fortune 100 and Government customers

5. Container Container Suite
5
https://github.com/CrunchyData/crunchy-containers
● Microservices architecture
● PostgreSQL/PostGIS Containers
(9.5, 9.6, 10.x, 11.x)
● PostgreSQL utility containers that
are the building blocks for running
production environments:
○ High Availability
○ Disaster recovery for
terabyte-scale clusters with
pgBackRest
○ Monitoring
● Open source
● Examples provided

6. Looks great!
But I have 50+ clusters to manage...

7. When to Use Kubernetes with PostgreSQL
● Value of Kubernetes increases
exponentially as number of containers
increases
● Due to statefulness of databases,
Kubernetes requires more knowledge
to successfully operate a standard
database workload:
○ Avoid scheduling and availability issues for
longer-running database containers
○ Data continues to exist even if container
does not

8. Crunchy PostgreSQL Operator Overview
● Open source project to provide a smarter way of provisioning PostgreSQL
clusters on Kubernetes
● Based on the Kubernetes client APIs, written in golang
● Custom Resource Definitions used to capture the definition of PostgreSQL
clusters and administration tasks
● REST API provides client integration, RBAC included for fine grained controls
● Goal is to assist in Day 2 operations as well as provisioning
● Single Deployment per Namespace, PostgreSQL clusters represented as
Deployments
● Leverages the Crunchy Container Suite set of microservice containers

9. ● Allows an administrator to run PostgreSQL-specific commands to
manage database clusters, including:
○ Creating / Deleting a cluster (your own DBaaS)
○ Scaling up / down replicas
○ Failover
○ Apply user policies to PostgreSQL instances
○ Define what container resources to use (RAM, CPU, etc.)
○ Smart pod deployments to nodes
○ Backup and restore
○ Backup scheduling
● REST API allows for easy integration with other services (e.g. pgo-
osb)
● The Crunchy PostgreSQL Operator enables your own secure,
elastic database-as-a-service
Crunchy PostgreSQL Operator Features

10. Crunchy PostgreSQL Operator Architecture
10
● Utilizes Kubernetes
Deployments
● Flexibility in storage
classes
● Flexibility in operating
environments
○ Node affinity
○ Resource (CPU, RAM)
configurations
● Flexibility in database
version runtimes

11. Why Use An Operator With PostgreSQL?
11
● Automation: Complex, multi-step DBA
tasks reduced to one-line commands
● Standardization: Many customizations,
same workflow
● Ease-of-Use: Simple CLI; UI in beta
● Scale
○ Provision & manage clusters quickly
amongst thousands of instances
○ Load balancing, disaster recovery,
security policies, deployment
specifications
● Security: Sandboxed environments,
RBAC, mass grant/revoke policies

12. Operator HA Support
The Crunchy PostgreSQL Operator
supports:
● PostgreSQL Deployments spread
across Kubernetes Nodes.
● Multiple storage backends within a
single PostgreSQL cluster
● High-availability through automated
and manual failover
● Rescheduling if a Kubernetes Node
becomes unavailable
● Storage providers replicating storage
between zones depending upon
storage vendor
12

13. Crunchy PostgreSQL Operator Successes
● Federal Government organizations’ deployments,
automated provisioning process from days to minutes
● Fortune 100 manufacturer deploying the Operator to build
an in-house database-as-a-service offering internally,
reducing provisioning times from weeks to seconds
● Fortune 250 customers using Container Suite and
Operator to simplify their development, test, QA
processes on on-premise and public cloud infrastructure
13

14. Crunchy PostgreSQL Operator Roadmap
● Open service broker implementation (pgo-osb) (underway)
● Web user interface (pgo-ui) (underway)
● pgBackRest integration (underway)
● Backup management
● Advanced Data loading
● Disk level snapshots
● archive/export/import
● Ingress integration
● Operator Federation (cross-namespace and cross-Kube-cluster)
● Additional advanced user management
● Automated Postgres Upgrading
● Sharding/Advanced Data Deployments

16. Next steps
Questions to consider
● Do you want to securely provision thousands of databases in a reliable, auditable environment?
● Do you want to be able to deploy your databases to ANY cloud platform, public or private, from a
single interface?
● Do you want to simply create highly-available PostgreSQL clusters with full disaster recovery
capabilities for databases of terabyte scale?
● Do you want to give your developers the ability to instantly provision databases that meet your
compliance requirements?
● Would the ability to leverage cost-effective open source used by Fortune 100 companies to
provision and manage thousands of databases be meaningful to your business?
