High Availability Postgres on Fly.io

This repo contains all the code and configuration necessary to run a highly available Postgres cluster in a Fly.io organization's private network. This source is packaged into Docker images which allow you to track and upgrade versions cleanly as new features are added.

Getting started

# Be sure you're running the latest version of flyctl.
fly version update
# Provision a 3 member cluster
fly pg create --name <app-name> --initial-cluster-size 3 --region ord

High Availability

For HA, it's recommended that you run at least 3 members within your primary region. Automatic failovers will only consider members residing within your primary region. The primary region is represented as an environment variable defined within the fly.toml file.

Horizontal scaling

Use the clone command to scale up your cluster.

# List your active Machines
fly machines list --app <app-name>
# Clone a machine into a target region
fly machines clone <machine-id> --region <target-region>

Staying up-to-date!

This project is in active development so it's important to stay current with the latest changes and bug fixes.

# Use the following command to verify you're on the latest version.
fly image show --app <app-name>
# Update your Machines to the latest version.
fly image update --app <app-name>

TimescaleDB support

We currently maintain a separate TimescaleDB-enabled image that you can specify at provision time.
