Single-VM deployment

The production deployment lives at:

/opt/idssys/TA-Deployment-Access

It consists of four containers:

TAPM broker, with an embedded SQLite database
Gitea, with its own embedded SQLite database and repository storage
Nginx, terminating TLS for the broker and Gitea
Certbot, run on demand for certificate issuance and renewal

Only Nginx ports 80 and 443 and Gitea SSH port 2222 are published. The broker and Gitea HTTP services are reachable only on the private tapm-edge Docker network.

1. VM and network

Install Docker Engine with Compose v2. Permit inbound TCP 80, 443, and 2222. Forward those ports from the datacenter edge to this VM. Create public DNS A/AAAA records for both application names before requesting the certificate.

Port 80 must remain reachable for HTTP-01 certificate renewal. If IPv6 is published, it must reach this same VM.

2. Install the repository

sudo mkdir -p /opt/idssys
sudo git clone GITEA-REPOSITORY-URL /opt/idssys/TA-Deployment-Access
sudo chown -R 1000:1000 /opt/idssys/TA-Deployment-Access
cd /opt/idssys/TA-Deployment-Access
cp .env.example .env
chmod 600 .env

Set BROKER_DOMAIN, GITEA_DOMAIN, and LETSENCRYPT_EMAIL first. Replace all example domains in the TAPM variables. Generate the cookie secret with:

openssl rand -base64 48

Runtime state is deliberately visible below the checkout:

config/
├── broker/              # tapm.db and SQLite WAL files
├── gitea/
│   ├── config/          # app.ini and Gitea configuration
│   └── data/            # repositories, packages, and gitea.db
├── letsencrypt/         # account data, certificate, and private key
├── certbot-webroot/     # HTTP-01 challenge files
└── backups/             # local offline snapshots

The contents are ignored by Git. They must never be committed.

3. Bootstrap Gitea and TLS

./manage.sh bootstrap

This prepares the runtime directories, creates the private Docker network, starts Gitea and the HTTP-only Nginx configuration, obtains one certificate covering both domains, and switches Nginx to TLS.

Create the initial Gitea administrator:

docker compose --env-file .env -f deploy/gitea/compose.yaml exec gitea \
  gitea admin user create \
  --admin --username taiadmin --email ADMIN-EMAIL \
  --password 'TEMPORARY-RANDOM-PASSWORD' --must-change-password

tapm-packages, with a read-only package token.
tapm-publisher, with a write package token.
An OAuth2 application whose callback is https://BROKER_DOMAIN/auth/callback.

Place those token and OAuth values in .env. The broker cannot start until all required credentials are present.

4. Start the complete deployment

./manage.sh start
./manage.sh status
curl --fail "https://BROKER_DOMAIN/health/ready"
curl --fail "https://GITEA_DOMAIN/api/healthz"

The broker automatically applies SQLite schema migrations before starting.

5. Move repositories

For each existing repository, create an empty matching repository in the new Gitea and mirror all refs:

git clone --mirror OLD-REPOSITORY-URL
cd REPOSITORY.git
git push --mirror ssh://git@GITEA_DOMAIN:2222/TAI/REPOSITORY.git

Update developer remotes, CI credentials, submodules, documentation, and the Go module path only if the hostname embedded in the module path is also changing. Move the deployment repository last so this checkout remains updateable during the transition.

6. Renewal and backups

Run renewal twice daily from root's crontab:

17 3,15 * * * cd /opt/idssys/TA-Deployment-Access && ./manage.sh renew

Create an application-consistent local snapshot with:

./manage.sh backup

The backup briefly stops both SQLite writers. Copy config/backups/ to storage outside the VM. A backup left only on this VM does not protect against VM or datacenter loss. Also back up .env through a secrets-aware system.

7. Updates

cd /opt/idssys/TA-Deployment-Access
git pull --ff-only
docker compose --env-file .env -f deploy/gitea/compose.yaml pull
./manage.sh start

Pin image versions as supplied and review release notes before changing them. Never change Gitea between rootless and rootful image families in place.
