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.
# 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
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.
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>
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>
We currently maintain a separate TimescaleDB-enabled image that you can specify at provision time.
fly pg create --image-ref flyio/postgres-flex-timescaledb:15
