# Deployment and CI/CD

## Current deployment model
- one private GitHub repository
- `develop` deploys to the test server
- `main` is reserved for production deployment
- GitHub Actions uploads the repository contents to the server over SSH
- the server does not need GitHub access to deploy

This is intentional. For a private repository, server-side `git clone` adds unnecessary credential management.

## Branch strategy
- `develop`: test deployment branch
- `main`: production branch
- feature branches: normal product work

## Environments
### Development / test
- target server: `192.168.2.55`
- deployment path: `/opt/workdock`
- stack file: `docker-compose.prod.yml`
- env file on server: `.env.test`
- current access URL: `http://192.168.2.55:8088`

### Production
- same deployment mechanism
- different server
- env file on server: `.env.prod`
- should run behind real HTTPS
- should keep `DEBUG=0`

## Important design choice
The current test server is a LAN-only HTTP deployment.

Because the Django settings enforce secure-cookie checks when `DEBUG=0`, the test deployment uses:
- `DJANGO_DEBUG=1`
- `RUN_DJANGO_CHECK=0`

That is acceptable for this internal test box only.

Production must use:
- `DJANGO_DEBUG=0`
- `DJANGO_SECURE_COOKIES=1`
- HTTPS
- `RUN_DJANGO_CHECK=1`

## Files used for deployment
- [docker-compose.prod.yml](/Users/bostame/Documents/workdock-platform/docker-compose.prod.yml)
- [scripts/deploy_stack.sh](/Users/bostame/Documents/workdock-platform/scripts/deploy_stack.sh)
- [backend/entrypoint-web-prod.sh](/Users/bostame/Documents/workdock-platform/backend/entrypoint-web-prod.sh)
- [backend/entrypoint-worker-prod.sh](/Users/bostame/Documents/workdock-platform/backend/entrypoint-worker-prod.sh)
- [deploy/Caddyfile](/Users/bostame/Documents/workdock-platform/deploy/Caddyfile)
- [.env.test.example](/Users/bostame/Documents/workdock-platform/.env.test.example)
- [.env.prod.example](/Users/bostame/Documents/workdock-platform/.env.prod.example)
- [.github/workflows/deploy-test.yml](/Users/bostame/Documents/workdock-platform/.github/workflows/deploy-test.yml)
- [.github/workflows/deploy-prod.yml](/Users/bostame/Documents/workdock-platform/.github/workflows/deploy-prod.yml)

## What `deploy_stack.sh` does
The deployment script:
1. validates the env file exists
2. builds `web`, `worker`, and `caddy`
3. starts `db` and `redis`
4. initializes writable volume ownership for:
   - `/app/media`
   - `/app/staticfiles`
   - `/app/backups`
5. runs:
   - `migrate`
   - `bootstrap_initial_users`
   - `collectstatic`
6. optionally runs `manage.py check`
7. starts:
   - `web`
   - `worker`
   - `caddy`
8. waits for `/healthz/`

## Proxmox / LXC requirement
This project is running in an Ubuntu CT on Proxmox, with Docker inside the CT.

For this to work, the CT needed Proxmox-side configuration in:
- `/etc/pve/lxc/<CTID>.conf`

Required settings:
```conf
features: nesting=1,keyctl=1
lxc.apparmor.profile: unconfined
lxc.mount.entry: /dev/null sys/module/apparmor/parameters/enabled none bind 0 0
```

Then restart the CT:
```bash
pct restart <CTID>
```

Without this, Docker containers in the CT fail with:
```text
open sysctl net.ipv4.ip_unprivileged_port_start ... permission denied
```

This is a Proxmox/LXC nested-Docker issue, not an application bug.

## Server bootstrap
Run on the server once:
```bash
apt-get update
apt-get install -y ca-certificates curl gnupg git
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(. /etc/os-release && echo $VERSION_CODENAME) stable" > /etc/apt/sources.list.d/docker.list
apt-get update
apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
systemctl enable --now docker
```

## Server directory layout
Current test server path:
```bash
/opt/workdock
```

Important server-local files:
- `/opt/workdock/.env.test`
- later `/opt/workdock/.env.prod`

These env files are intentionally not uploaded from GitHub Actions.

## Test env file
Create on the server:
```bash
cp .env.test.example .env.test
```

Current important values for the LAN test box:
```env
DJANGO_DEBUG=1
DJANGO_ALLOWED_HOSTS=192.168.2.55,localhost,127.0.0.1
DJANGO_CSRF_TRUSTED_ORIGINS=http://192.168.2.55:8088
DJANGO_SECURE_COOKIES=0
DJANGO_SECURE_SSL_REDIRECT=0
APP_PORT=8088
SITE_ADDRESS=:80
```

Generate strong values for:
- `DJANGO_SECRET_KEY`
- `POSTGRES_PASSWORD`

## Production env file
Production should use:
```env
DJANGO_DEBUG=0
DJANGO_SECURE_COOKIES=1
DJANGO_SECURE_SSL_REDIRECT=1
```

And a real HTTPS hostname in:
- `DJANGO_ALLOWED_HOSTS`
- `DJANGO_CSRF_TRUSTED_ORIGINS`
- `SITE_ADDRESS`

## Manual test deployment
If you need to deploy manually on the test server:
```bash
cd /opt/workdock
RUN_DJANGO_CHECK=0 DEPLOY_HEALTH_URL="http://127.0.0.1:8088/healthz/" ./scripts/deploy_stack.sh .env.test docker-compose.prod.yml
```

Manual production deployment:
```bash
cd /opt/workdock
RUN_DJANGO_CHECK=1 ./scripts/deploy_stack.sh .env.prod docker-compose.prod.yml
```

## GitHub Actions workflows
### Test deployment workflow
File:
- [deploy-test.yml](/Users/bostame/Documents/workdock-platform/.github/workflows/deploy-test.yml)

Behavior:
- triggers on push to `develop`
- can also be run manually with `workflow_dispatch`
- checks out the repo in GitHub Actions
- uploads the working tree to the server over SSH
- runs the server deployment script

### Production deployment workflow
File:
- [deploy-prod.yml](/Users/bostame/Documents/workdock-platform/.github/workflows/deploy-prod.yml)

Behavior:
- manual only
- uploads the working tree to the production server
- runs the production deployment script

## GitHub environment setup
In GitHub:
1. open repository settings
2. open `Environments`
3. create:
   - `development`
   - `production`

### Exact GitHub UI path
1. Open the private repository:
   - `https://github.com/Bostame/workdock-platform`
2. Click:
   - `Settings`
3. In the left sidebar, open:
   - `Environments`
4. Click:
   - `New environment`
5. Create:
   - `development`
6. Repeat and create:
   - `production`
7. Open the `development` environment
8. Under `Environment secrets`, click:
   - `Add environment secret`
9. Add each required secret one by one
10. Repeat the same pattern later for `production`

### Development environment secrets
Add:
- `TEST_DEPLOY_HOST`
- `TEST_DEPLOY_USER`
- `TEST_DEPLOY_PORT`
- `TEST_DEPLOY_PATH`
- `TEST_DEPLOY_SSH_KEY`

Current test values:
- `TEST_DEPLOY_HOST=192.168.2.55`
- `TEST_DEPLOY_USER=root`
- `TEST_DEPLOY_PORT=22`
- `TEST_DEPLOY_PATH=/opt/workdock`
- `TEST_DEPLOY_SSH_KEY=<private key that can ssh to root@192.168.2.55>`

### Development secret entry example
Use these exact values in the `development` environment:

`TEST_DEPLOY_HOST`
```text
192.168.2.55
```

`TEST_DEPLOY_USER`
```text
root
```

`TEST_DEPLOY_PORT`
```text
22
```

`TEST_DEPLOY_PATH`
```text
/opt/workdock
```

`TEST_DEPLOY_SSH_KEY`
```text
<paste the full private SSH key that can log in to root@192.168.2.55>
```

The SSH key must include the full multi-line content, for example:
```text
-----BEGIN OPENSSH PRIVATE KEY-----
...
-----END OPENSSH PRIVATE KEY-----
```

### How to verify the SSH key before adding it
From your local machine:
```bash
ssh -4 root@192.168.2.55
```

If that works without asking for a password, the matching private key is the correct one to store in `TEST_DEPLOY_SSH_KEY`.

### Production environment secrets
Add:
- `PROD_DEPLOY_HOST`
- `PROD_DEPLOY_USER`
- `PROD_DEPLOY_PORT`
- `PROD_DEPLOY_PATH`
- `PROD_DEPLOY_SSH_KEY`

## How the CI/CD test deploy works
### Normal flow
1. push code to `develop`
2. GitHub Actions runs `Deploy Test`
3. workflow uploads repository contents to `/opt/workdock`
4. server keeps its local `.env.test`
5. `deploy_stack.sh` rebuilds and restarts the stack
6. workflow succeeds only after `/healthz/` is healthy

### Manual trigger
From GitHub Actions:
1. open `Deploy Test`
2. click `Run workflow`

### First GitHub Actions validation
After you add the `development` environment secrets:
1. Open:
   - `https://github.com/Bostame/workdock-platform/actions`
2. Open workflow:
   - `Deploy Test`
3. Click:
   - `Run workflow`
4. Select branch:
   - `develop`
5. Run it
6. Wait until both steps complete:
   - upload bundle
   - deploy over SSH
7. Verify:
   - `http://192.168.2.55:8088/healthz/`
8. Then open the app home page in the browser

### What success looks like
- workflow status is green in GitHub Actions
- `Deploy Test` job finishes without SSH or health-check errors
- `/healthz/` returns `200 OK`
- the containers on the test server remain up

### If the workflow fails
Check in this order:
1. wrong or incomplete `TEST_DEPLOY_SSH_KEY`
2. wrong `TEST_DEPLOY_USER`
3. wrong `TEST_DEPLOY_PATH`
4. changed server host key
5. server disk-space or Docker runtime issue

## How to validate a deployment
### From your machine
```bash
curl -I http://192.168.2.55:8088/healthz/
```

### On the server
```bash
cd /opt/workdock
docker compose --env-file .env.test -f docker-compose.prod.yml ps
docker compose --env-file .env.test -f docker-compose.prod.yml logs --tail=100 web
docker compose --env-file .env.test -f docker-compose.prod.yml logs --tail=100 worker
docker compose --env-file .env.test -f docker-compose.prod.yml logs --tail=100 caddy
```

## Rollback
This deployment path is source-upload based, not image-tag based.

Rollback options:
1. revert the bad commit on `develop` and let GitHub Actions deploy again
2. manually re-upload a previous working checkout and rerun `deploy_stack.sh`

For production, you may later want image-tag based rollback. That is not necessary yet for the test box.

## Operational notes
- server-local env files must survive deployments
- do not store `.env.test` or `.env.prod` in Git
- test deployment is intentionally weaker than production on transport security
- production should not reuse the test env model

## Current known-good state
Validated manually:
- repository pushed to private GitHub
- server bootstrap completed
- test stack deployed successfully
- health check reachable at:
  - `http://192.168.2.55:8088/healthz/`
