draw-things

Draw Things gRPC server — the official CLI image that exposes a gRPC API for Stable Diffusion image generation, intended to be paired with the macOS/iOS Draw Things app for remote inference on a beefier GPU than your phone. This chart packages it with the bjw-s common library so behaviour is driven almost entirely from values.yaml.

TL;DR

helm repo add obeone https://charts.obeone.cloud
helm repo update
helm install draw-things obeone/draw-things

About

Draw Things is an image-generation app for Apple devices (macOS, iOS, iPadOS). This chart deploys its gRPC server, the official offload backend: the app connects to it and delegates the heavy diffusion work to a machine with a proper GPU, so your laptop or phone stays cool while the cluster does the sweating.

• Application: drawthings.ai
• Container image: drawthingsai/draw-things-grpc-server-cli
• Chart source: charts/draw-things

Prerequisites

• Helm 3
• A Kubernetes cluster matching the chart’s kubeVersion constraint (see Chart.yaml)
• A GPU node is strongly recommended: CPU-only generation works but is painfully slow

Configuration

This chart is built on the bjw-s-labs common library. Most configuration keys (controllers, service, ingress, persistence, …) follow its schema; see the common library documentation for everything it supports beyond what is spelled out in values.yaml.

Defaults are meant to work out of the box on any cluster. The full list of options lives in values.yaml, is validated by values.schema.json at install time, and is documented in the Values section below. Override it with your own values file:

helm install draw-things obeone/draw-things -f my-values.yaml

Upgrading

helm repo update
helm upgrade draw-things obeone/draw-things

Each release lists its changes in the Artifact Hub changelog; give it a look before jumping across several chart versions.

Uninstalling

helm uninstall draw-things

PersistentVolumeClaims created by the chart are kept around: delete them manually if you also want the data gone.

Verifying the chart signature

Charts in this repository are signed with GPG and every release ships a provenance file. The public key is available at charts.obeone.cloud/public_key.gpg, fingerprint B9FE852F28888D27F8C9A11CD33E04CD22E335CE.

# Import the signing key into a legacy keyring (helm verifies with GnuPG v1 keyrings)
curl -fsSL https://charts.obeone.cloud/public_key.gpg | gpg --import
gpg --export > ~/.gnupg/pubring.gpg

# Pull the chart and check it against its provenance file
helm pull --verify obeone/draw-things

Support

This is a personal chart repository, maintained on a best-effort basis. Bug reports and contributions are welcome on GitHub.
