@eliware/knit

GitHub webhook handler and SSH deployment automation service.

Runtime

• Node.js >=26; ESM.
• POST / receives signed GitHub webhooks.
• GET /health returns service status and version.
• Repository configuration is YAML mounted at KNIT_CONFIG_PATH (default ./repos).
• YAML files use <owner>__<repo>.yaml naming in Kubernetes ConfigMaps.

Configuration

Modern configuration uses SSH targets:

repository: owner/reponotifyKey: owner__repogit:
url: git@github.com:owner/repo.gitref: maintargets:
- name: devhost: dev.exampleuser: rootworkingDirectory: /opt/repopre: []post: []execution:
mode: sequentialstopOnError: true

notifyKey resolves to /run/secrets/discord-webhooks/<notifyKey>. Webhook URLs belong in Kubernetes Secrets, encrypted in GitOps with SOPS/age. They must not appear in configuration files. SSH assets are mounted at /run/secrets/eliware/ssh/.

Targets execute commands over SSH with strict host verification. identity and knownHosts may be host-installed or paths relative to the configured path. Modern targets are SSH-only.

New configurations must use YAML and SSH targets. Local Compose requires KNIT_CONFIG_PATH and KNIT_DISCORD_WEBHOOK_SECRET_HOST_PATH directories; systemd requires equivalent mounted/provisioned paths.

Knit self-deployment and organization fallback

eliware/knit is configured as the fallback target for organization-level GitHub events. Its push deployment runs git pull, npm install, and npm test on dev.purinton.us:/opt/knit, then sends the result to Discord. Successful deployments do not restart the process; release a new image and let Argo CD roll it out for Knit code changes.

Environment

Variable	Purpose
PORT	Listen port; default 3456
GITHUB_WEBHOOK_SECRET	GitHub signature secret
LOG_LEVEL	Logger level
KNIT_CONFIG_PATH	Mounted configuration directory
KNIT_DISCORD_WEBHOOK_SECRET_PATH	Mounted Discord webhook Secret directory

Development

npm install
npm test
npm run lint
npm start

Kubernetes releases use immutable container images and Argo CD GitOps. Knit can receive its own repository webhook and SSH-deploy /opt/knit; new Knit code is delivered by releasing an image, not by runtime self-updating.
