mngr Vultr Provider

Vultr provider backend plugin for mngr. Runs agents in Docker containers on Vultr VPS instances.

See mngr_vps_docker for the base architecture and shared infrastructure.

Setup

Set VULTR_API_KEY in your environment or add api_key to the provider config in ~/.mngr/config.toml:

[providers.vultr]
backend = "vultr"
api_key = "YOUR_VULTR_API_KEY"

Usage

mngr create my-agent --provider vultr
mngr create my-agent --provider vultr -b --region=sjc -b --plan=vc2-2c-4gb
mngr list
mngr exec my-agent "echo hello"
mngr stop my-agent
mngr start my-agent
mngr destroy my-agent

Vultr-specific configuration

These fields extend the base VpsDockerProviderConfig (see mngr_vps_docker):

Implementation details

• Uses raw HTTP calls to the Vultr API v2 (https://api.vultr.com/v2), no third-party SDK
• VPS instances are tagged with mngr-provider=<name> and mngr-host-id=<id> for discovery
• SSH keys are uploaded to the Vultr SSH key store and referenced by ID during instance creation
• Discovery works by listing all Vultr instances with matching tags, then SSH-ing to each VPS to read host records from the state volume
