buzz/deploy/compose

Buzz Docker Compose deployment

This is the single-node/VPS deployment bundle. It is intentionally separate from the root docker-compose.yml, which remains local development infrastructure.

Quick start

cd deploy/compose
cp .env.example .env
$EDITOR .env       # replace every CHANGE_ME value
./run.sh start

For a public VPS with automatic Let's Encrypt certificates:

cd deploy/compose
BUZZ_COMPOSE_TLS=true ./run.sh start

The bootstrap script should eventually replace manual .env editing for normal users. It is responsible for generating stable secrets and, optionally, an owner keypair.

Production notes

• Requires Docker Compose v2.24.4 or newer; the TLS override uses Compose's !reset tag to remove the direct relay port when Caddy terminates HTTPS.
• Default BUZZ_IMAGE tracks ghcr.io/block/buzz:main for early testing. Pin it to ghcr.io/block/buzz:sha-<7> or a semver release tag for production once available.
• Keep BUZZ_RELAY_PRIVATE_KEY, BUZZ_GIT_HOOK_HMAC_SECRET, database/Redis, Typesense, and S3 secrets stable across restarts.
• RELAY_OWNER_PUBKEY is intentionally not prefixed with BUZZ_; it must be a 64-character hex Nostr pubkey when closed relay mode is enabled.
• BUZZ_AUTO_MIGRATE=true requires an image that includes embedded SQLx migrations. Do not share this quick start for a fresh public install until PR #988 is merged and ghcr.io/block/buzz:main has been rebuilt from it. Before then, this bundle is only suitable for instances whose database schema has already been applied.
• The stack uses Postgres, Redis, Typesense, MinIO, and a git data volume because those are real Buzz dependencies today. Minimal mode can simplify this later.

Run ./run.sh backup-hint for the backup checklist.

Validation

Before sharing an install link publicly, verify a fresh install with:

cd deploy/compose
cp .env.example .env
$EDITOR .env
./run.sh config
./run.sh start
curl -fsS "http://127.0.0.1:$(grep -E '^BUZZ_HTTP_PORT=' .env | cut -d= -f2-)/_liveness"
./run.sh status
