# Updating PocketVeto — Remote Server Setup & Deployment Workflow

How to push new code from your development machine and pull it on the production server.

---

## Overview

The workflow is:

```
Local machine  →  git push  →  git.jackhlevy.com  →  (pull on server)  →  docker compose up --build -d
```

You develop locally, push to the Gitea remote, then update the production server — either manually over SSH or via an automated webhook.

---

## 1. SSH access to the production server

Make sure you can SSH into the server without a password:

```bash
# On your local machine — generate a key if you don't have one
ssh-keygen -t ed25519 -C "pocketveto-deploy"

# Copy the public key to the server
ssh-copy-id user@YOUR_SERVER_IP
```

Test:
```bash
ssh user@YOUR_SERVER_IP "echo ok"
```

---

## 2. Server: clone the repo and authenticate

On the server, clone from your Gitea instance:

```bash
ssh user@YOUR_SERVER_IP
cd /opt                           # or wherever you want to host it
git clone https://git.jackhlevy.com/jack/civicstack.git
cd civicstack
```

If your Gitea repo is private, create a **deploy token** in Gitea:

- Gitea → Repository → Settings → Deploy Keys → Add Deploy Key (read-only is fine)
- Or: Gitea → User Settings → Applications → Generate Token

Store credentials so `git pull` doesn't prompt:
```bash
# Using a personal access token stored in the URL
git remote set-url origin https://YOUR_TOKEN@git.jackhlevy.com/jack/civicstack.git
```

Verify:
```bash
git pull    # should succeed with no password prompt
```

---

## 3. Option A — Manual update (simplest)

SSH in and run:

```bash
ssh user@YOUR_SERVER_IP
cd /opt/civicstack

git pull origin main
docker compose up --build -d
```

That's it. Docker rebuilds only the images that changed (layer cache means unchanged services rebuild in seconds). Migrations run automatically when the API container restarts.

**One-liner from your local machine:**
```bash
ssh user@YOUR_SERVER_IP "cd /opt/civicstack && git pull origin main && docker compose up --build -d"
```

---

## 4. Option B — Deploy script

Create `/opt/civicstack/deploy.sh` on the server:

```bash
#!/bin/bash
set -e

cd /opt/civicstack

echo "==> Pulling latest code"
git pull origin main

echo "==> Building and restarting containers"
docker compose up --build -d

echo "==> Done. Current status:"
docker compose ps
```

```bash
chmod +x /opt/civicstack/deploy.sh
```

Now from your local machine:
```bash
ssh user@YOUR_SERVER_IP /opt/civicstack/deploy.sh
```

---

## 5. Option C — Automated webhook (Gitea → server)

This triggers a deploy automatically every time you push to `main`.

### 5a. Create a webhook listener on the server

Install a simple webhook runner. The easiest is [`webhook`](https://github.com/adnanh/webhook):

```bash
apt install webhook
```

Create `/etc/webhook/hooks.json`:
```json
[
  {
    "id": "civicstack-deploy",
    "execute-command": "/opt/civicstack/deploy.sh",
    "command-working-directory": "/opt/civicstack",
    "response-message": "Deploying...",
    "trigger-rule": {
      "match": {
        "type": "payload-hmac-sha256",
        "secret": "your-webhook-secret",
        "parameter": { "source": "header", "name": "X-Gitea-Signature-256" }
      }
    }
  }
]
```

Start the webhook service:
```bash
# Test it first
webhook -hooks /etc/webhook/hooks.json -port 9000 -verbose

# Or create a systemd service (recommended)
```

`/etc/systemd/system/webhook.service`:
```ini
[Unit]
Description=Webhook listener for civicstack deploys
After=network.target

[Service]
ExecStart=/usr/bin/webhook -hooks /etc/webhook/hooks.json -port 9000
Restart=on-failure
User=root

[Install]
WantedBy=multi-user.target
```

```bash
systemctl enable --now webhook
```

Expose port 9000 (or proxy it through nginx/Caddy at a path like `/hooks/`).

### 5b. Add the webhook in Gitea

- Gitea → Repository → Settings → Webhooks → Add Webhook → Gitea
- **Target URL:** `http://YOUR_SERVER_IP:9000/hooks/civicstack-deploy`
- **Secret:** same value as `your-webhook-secret` above
- **Trigger:** Push events → branch `main`

Now every `git push origin main` automatically triggers a deploy.

---

## 6. Checking the deployed version

After any update you can confirm what's running:

```bash
# Check the git commit on the server
ssh user@YOUR_SERVER_IP "cd /opt/civicstack && git log --oneline -3"

# Check container status
ssh user@YOUR_SERVER_IP "cd /opt/civicstack && docker compose ps"

# Hit the health endpoint
curl http://YOUR_SERVER_IP/api/health
```

---

## 7. Rolling back

If a bad deploy goes out:

```bash
ssh user@YOUR_SERVER_IP
cd /opt/civicstack

# Roll back to the previous commit
git revert HEAD --no-edit      # preferred — creates a revert commit, keeps history clean

# Or hard reset if you're sure (discards the bad commit locally — use with care)
# git reset --hard HEAD~1

git push origin main           # if using Option C, this triggers a new deploy automatically
docker compose up --build -d   # if manual
```

---

## 8. Environment and secrets

`.env` is **not** tracked in git. If you need to update a secret or add a new API key on the server:

```bash
ssh user@YOUR_SERVER_IP
nano /opt/civicstack/.env

# Then restart only the affected services (usually api + worker)
cd /opt/civicstack
docker compose up -d --no-build api worker beat
```

`--no-build` skips the rebuild step — only a config reload is needed for env var changes.

## Summary

| Goal | Command |
|---|---|
| Manual deploy | `ssh server "cd /opt/civicstack && git pull && docker compose up --build -d"` |
| One-step deploy script | `ssh server /opt/civicstack/deploy.sh` |
| Automated on push | Gitea webhook → webhook listener → `deploy.sh` |
| Rollback | `git revert HEAD` + redeploy |
| Update env only | Edit `.env` on server + `docker compose up -d --no-build api worker beat` |
| Check what's running | `ssh server "cd /opt/civicstack && git log --oneline -1 && docker compose ps"` |
