• response playback
• service exposed in HA to start and stop the voice assistant from another device/trigger
• visual feedback of the recording/success/error status via the Luxe's onboard LED

GPU Support For Docker Swarm

Docker compose has nice support for GPUs, K8s has moved their cluster-wide GPU scheduler from experimental to stable status. Docker swarm has yet to support the device option used in docker compose so the mechanisms for supporting GPUs on swarm are a bit more open-ended.

Basic documentation

• NVIDIA container runtime for docker. The runtime is no longer required to run GPU support with the docker cli or compose; however, it appears necessary so that one can set Default Runtime: nvidia for swarm mode.
• docker compose GPU support
• Good GitHub Gist Reference for an overview on Swarm with GPUs. It is a bit dated, but has good links and conversation.
• [Miscellaneous Opt

WireGuard Site-to-Site

Accessing a subnet that is behind a WireGuard client using a site-to-site setup

Problem Summary

We want to access a local subnet remotely, but it is behind a NAT firewall and we can't setup port forwarding. Outgoing connections work, but all incoming connections get DROPPED by the ISP's routing policy.

Replace your Swarm Manager and Workers with updated versions of docker

• it's best to replace nodes, don't do apt/yum upgrades.
• both would work, but VM replacment forces me to think of it as immutable and prevents making pets
• if you don't want to update join scripts for manager IP's, then do something like Elastic IP's so manager IP's won't change.

Lets assume you have 3 managers and 3 workers on 17.06 and you want to update to 17.12

• managers: m1, m2, m3
