Dragonfly

Towbar’s dragonfly preset runs Dragonfly 1.33 on amd64 or arm64. It listens on port 6379, stores snapshots in /data, and exposes the Redis protocol with password authentication.

Declare the resource

.towbar/resources/dragonfly.resource.yml

id: dragonfly
name: Dragonfly
type: dragonfly
container:
  network: application
  networkAlias: dragonfly
  resources:
    cpus: 0.5
    memory: 512m
access:
  sshTunnel:
    hostPort: 16380
secrets:
  runtime:
    - REDIS_PASSWORD
environments:
  production:
    server: 192.0.2.10

Towbar requires REDIS_PASSWORD, passes it to Dragonfly as requirepass, and uses it for health, backup, and restore operations.

Connect from an app

Use a Redis-compatible client and connect to dragonfly:6379 from containers on the application network. Store the connection URL in the app’s runtime secrets. The optional tunnel binds 16380 only to server loopback.

Operational boundary

Dragonfly implements the Redis protocol but has its own engine and supported major version. Do not treat a Towbar restore as a cross-engine conversion between Redis, Dragonfly, and KeyDB. Changing the password also requires a coordinated client update and redeployment.

Back up and restore

Towbar creates and verifies an RDB snapshot and restores it into a fresh Dragonfly target volume. Recovery requires the Dragonfly preset and supported major version 1. Continue with Database backups and Database restores.
