hantim-server

Server provisioning and app management for the hantim webserver. This repo lives at /opt/hantim on the server and contains Docker Compose configs, deploy scripts, nginx configs, and Gitea Actions workflows for each app.

See ARCHITECTURE.md for technical deep-dives, USECASES.md for expected behaviors.

Infrastructure overview

Two servers and a cloud secrets service:

• Hantim (Vultr, Rocky Linux 9) — production web server running nginx, app containers, and a Garage storage node via Docker Compose
• Argento (home server) — Gitea instance (git.timothykim.net) with Docker registry, CI runner, and a second Garage storage node (with web UI)
• Bitwarden Secrets Manager (cloud) — all secrets, fetched via the bws CLI

All app containers share a shared Docker network. Only nginx binds host ports (80/443). Garage provides S3-compatible media storage replicated across both nodes.

Provisioning a new server

On a fresh Rocky Linux 9 install:

dnf install -y git
git clone https://git.timothykim.net/hantim/hantim-server.git /opt/hantim
bash /opt/hantim/scripts/bootstrap.sh

bootstrap.sh runs once manually. It installs dependencies, sets up the bws CLI, creates the deploy user, and calls configure.sh.

configure.sh is idempotent and CI-safe. It opens firewall ports, sets up certbot renewal, and deploys all services (nginx first, then apps).

Prerequisites:

• DNS for all configured domains must point to the server
• Bitwarden Secrets Manager access token for the hantim-server machine account

Restoring from backup is identical — run the same three commands on a fresh server. Everything is idempotent.

Adding a new static site

./tools/new-app.sh <domain>

This single command handles everything: DNS records (Vultr), Gitea repo (from static-site-template), nginx/compose/workflow configs, SSL cert, Garage media bucket, first build, and verification.

Prerequisites: domain nameservers pointed to Vultr, bws/jq/dig installed, BWS_ACCESS_TOKEN env var or token at ~/.config/hantim/bws-token.

After the site is live, clone the app repo and customize:

git clone git@git.timothykim.net:hantim/<domain>.git
cd <domain>
# edit content
git add . && git commit -m "initial content" && git push

Deploying changes

App code change — push to an app repo (e.g., example.com):

• build.yml builds the image, pushes to registry, SSHes to server to deploy

Compose/nginx config change — push to this repo:

• Path-matched workflows trigger and SSH to server
• nginx deploys test config before applying (nginx -t)

Setup change — push changes to scripts/configure.sh:

• provision.yml triggers and re-runs configure.sh

Media hosting

Media files are stored in Garage and served via nginx at /media/ on each domain. This keeps large files out of git repos.

Endpoints:

• s3.hantim.net — S3 API for uploads (authenticated)
• garage.hantim.net — Admin API for bucket management
• https://www.<domain>/media/<path> — public file access

Uploading:

# One-time AWS CLI setup
aws configure  # key ID + secret from bws, region: garage, output: json
# Then add to ~/.aws/config under [default]:
#   endpoint_url = https://s3.hantim.net

# Upload
aws s3 cp photo.jpg s3://example.com/photo.jpg
aws s3 sync static/media/ s3://example.com/

Local development: store media in static/media/ (gitignored) so files are accessible at /media/ when serving locally.

Creating buckets manually (for existing domains without buckets):

# Get admin token and media key ID from bws
# Create bucket
curl -X POST -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"globalAlias": "example.com"}' https://garage.hantim.net/v2/CreateBucket
# Note the bucket ID from the response, then:
curl -X POST -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"bucketId": "BUCKET_ID", "accessKeyId": "MEDIA_KEY_ID", "permissions": {"read": true, "write": true, "owner": false}}' \
  https://garage.hantim.net/v2/AllowBucketKey
curl -X POST -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"websiteAccess": {"enabled": true, "indexDocument": "index.html"}}' \
  "https://garage.hantim.net/v2/UpdateBucket?id=BUCKET_ID"

Garage cluster initialization

After provisioning a fresh server, Garage connects to argento automatically. The cluster layout must be assigned manually once (node IDs change per install):

docker exec garage /garage status
docker exec garage /garage layout assign <hantim-node-id> -z hantim -c 1G
docker exec garage /garage layout assign <argento-node-id> -z argento -c 1G
docker exec garage /garage layout apply --version 1

If only hantim is reprovisioned, argento retains the layout and hantim reconnects automatically.

Secrets

Bitwarden Secrets Manager

Project: hantim. Fetched via bws CLI on the server.

Secret	Purpose	Used by
hantim-ci-registry-push	Gitea token for Docker registry	bootstrap.sh
hantim-deploy-ssh-public-key	Deploy user's SSH public key	bootstrap.sh
hantim-deploy-ssh-private-key	Deploy user's SSH private key	new-app.sh
hantim-new-app-script	Gitea API token for creating repos	new-app.sh
hantim-vultr-api-key	Vultr API key for DNS management	new-app.sh
hantim-garage-rpc-secret	Garage cluster RPC secret	deploy.sh
hantim-garage-argento-node-id	Argento's Garage node ID + address	deploy.sh
hantim-garage-admin-token	Garage admin API token	deploy.sh, new-app.sh
hantim-garage-media-key-id	S3 access key ID for media uploads	new-app.sh, aws CLI
hantim-garage-media-secret-key	S3 secret key for media uploads	aws CLI

Machine accounts: hantim-server (token at /etc/bws-token), hantim-ci (reserved).

Service secrets (.env.keys)

Services that need secrets declare them in .env.keys (format: ENV_VAR=bws-secret-name, one per line). deploy.sh fetches each secret from bws and generates .env before starting the service.

Gitea org-level secrets

Stored in the hantim Gitea org for direct use in CI workflows:

Name	Type	Purpose
DEPLOY_HOST	Variable	Server IP or hostname
DEPLOY_SSH_KEY	Secret	SSH private key for the deploy user
CI_REGISTRY_TOKEN	Secret	Gitea token for Docker registry login
