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.

Repo structure

docker/
  nginx/               # Reverse proxy (nginx:alpine) + SSL config
    nginx.conf         # Main nginx config
    conf.d/            # Per-app server blocks (e.g. timothykim.net.conf)
    compose.yml
  timothykim.net/      # timothykim.net static site
    compose.yml
scripts/
  deploy.sh            # Deploy + cert issuance script (called via SSH)
  new-app.sh           # Scaffolding script to add a new app
setup.sh               # Server provisioning script (idempotent)
.gitea/workflows/      # Per-app deploy workflows triggered by path changes

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/setup.sh

setup.sh is fully automated and idempotent. It:

1. Installs system dependencies (git-crypt, jq, certbot, Node.js 20, Docker)
2. Installs and authenticates the Bitwarden CLI
3. Unlocks git-crypt using a key stored in Bitwarden
4. Fetches the Docker registry token and deploy SSH public key from Bitwarden
5. Logs into the Gitea Docker registry
6. Creates the deploy user with restricted SSH access and sudo
7. Opens firewall ports (HTTP/HTTPS)
8. Issues SSL certificates via certbot for all configured domains
9. Starts all services (nginx first, then all apps)

Prerequisites: DNS for all configured domains must point to the server before running setup.

Adding a new app

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

Example: ./scripts/new-app.sh hcsuzuki.net

This single command handles everything: creates DNS records on Vultr, creates the Gitea repo from static-site-template, generates all config files, issues the SSL cert (zero downtime), commits and pushes, triggers the first build, and verifies the site is live.

Prerequisites: domain nameservers pointed to Vultr, bw/jq/dig installed. Uses the deploy SSH key from Bitwarden -- no personal server access needed. See USECASES.md for full details.

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

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 like timothykim.net):

• The app's build.yml builds the Docker image, pushes to the registry, and SSHes into the server to trigger a deploy

Compose or nginx config change (push to this repo):

• Gitea Actions workflows trigger based on which docker/<app>/ paths changed
• deploy.sh pulls the latest code and runs docker compose up -d
• For nginx deploys, the config is tested before applying to prevent downtime

Restoring from backup

Run the same three commands as provisioning. setup.sh is idempotent:

• Existing packages are skipped
• Existing certs are skipped (or re-issued if the server is new)
• All services are started

Secrets

The following are stored in Bitwarden and fetched automatically by setup.sh:

Bitwarden item	Type	Purpose
hantim-git-crypt-key	Secure Note	git-crypt symmetric key (base64)
hantim-ci-registry-push	Secure Note	Gitea token for Docker registry
hantim-server-deploy	SSH Key	Deploy user's SSH key

The following are configured in the hantim Gitea org settings:

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

The following are stored in Bitwarden and used by new-app.sh:

Bitwarden item	Type	Purpose
hantim-new-app-script	Secure Note	Gitea API token for creating repos
hantim-vultr-api-key	Secure Note	Vultr API key for DNS management
