honeyDueAPI/deploy

Deploy Folder

This folder is the full production deploy toolkit for honeyDueAPI-go.

Run deploy with:

./.deploy_prod

The script will refuse to run until all required values are set.

First-Time Prerequisite: Create The Swarm Cluster

You must do this once before ./.deploy_prod can work.

1. SSH to manager #1 and initialize Swarm:

docker swarm init --advertise-addr <manager1-private-ip>

2. On manager #1, get join commands:

docker swarm join-token manager
docker swarm join-token worker

3. SSH to each additional node and run the appropriate docker swarm join ... command.

4. Verify from manager #1:

docker node ls

Security Requirements Before Public Launch

Use this as a mandatory checklist before you route production traffic.

1) Firewall Rules (Node-Level)

Apply firewall rules to all Swarm nodes:

• SSH port (for example 2222/tcp): your IP only
• 80/tcp, 443/tcp: Hetzner LB only (or Cloudflare IP ranges only if no LB)
• 2377/tcp: Swarm nodes only
• 7946/tcp,udp: Swarm nodes only
• 4789/udp: Swarm nodes only
• Everything else: blocked

2) SSH Hardening

On each node, harden /etc/ssh/sshd_config:

Port 2222
PermitRootLogin no
PasswordAuthentication no
PubkeyAuthentication yes
AllowUsers deploy

3) Cloudflare Origin Lockdown

• Keep public DNS records proxied (orange cloud on).
• Point Cloudflare to LB, not node IPs.
• Do not publish Swarm node IPs in DNS.
• Enforce firewall source restrictions so public traffic cannot bypass Cloudflare/LB.

4) Secrets Policy

• Keep runtime secrets in Docker Swarm secrets only.
• Do not put production secrets in git or plain .env files.
• ./.deploy_prod already creates versioned Swarm secrets from files in deploy/secrets/.
• Rotate secrets after incidents or credential exposure.

5) Data Path Security

• Neon/Postgres: DB_SSLMODE=require, strong DB password, Neon IP allowlist limited to node IPs.
• Backblaze B2: HTTPS only, scoped app keys (not master key), least-privilege bucket access.
• Swarm overlay: encrypted network enabled in stack (driver_opts.encrypted: "true").

6) Dozzle Hardening

• Keep Dozzle private (no public DNS/ingress).
• Put auth/SSO in front (Cloudflare Access or equivalent).
• Prefer a Docker socket proxy with restricted read-only scope.

7) Backup + Restore Readiness

• Postgres PITR path tested in staging.
• Redis persistence enabled and restore path tested.
• Written runbook for restore and secret rotation.
• Named owner for incident response.

Files You Fill In

Paste your values into these files:

• deploy/cluster.env
• deploy/registry.env
• deploy/prod.env
• deploy/secrets/postgres_password.txt
• deploy/secrets/secret_key.txt
• deploy/secrets/email_host_password.txt
• deploy/secrets/fcm_server_key.txt
• deploy/secrets/apns_auth_key.p8

If one is missing, the deploy script auto-copies it from its .example template and exits so you can fill it.

What ./.deploy_prod Does

1. Validates all required config files and credentials.
2. Builds and pushes api, worker, and admin images.
3. Uploads deploy bundle to your Swarm manager over SSH.
4. Creates versioned Docker secrets on the manager.
5. Deploys the stack with docker stack deploy --with-registry-auth.
6. Waits until service replicas converge.
7. Runs an HTTP health check (if DEPLOY_HEALTHCHECK_URL is set).

Useful Flags

Environment flags:

• SKIP_BUILD=1 ./.deploy_prod to deploy already-pushed images.
• SKIP_HEALTHCHECK=1 ./.deploy_prod to skip final URL check.
• DEPLOY_TAG=<tag> ./.deploy_prod to deploy a specific image tag.

Important

• deploy/shit_deploy_cant_do.md lists the manual tasks this script cannot automate.
• Keep real credentials and secret files out of git.
