## DNS
|
||
|
|
|
||
|
|
Internal names: `*.dell-atc.lan` (see `config/hosts/atc-lab.hosts`).
|
||
|
|
|
||
|
|
| Pattern | Example |
|
||
|
|
|---------|---------|
|
||
|
|
| Short hostname | `atc-lake01` |
|
||
|
|
| FQDN | `atc-lake01.dell-atc.lan` |
|
||
|
|
|
||
|
|
## Key ports (east-west)
|
||
|
|
|
||
|
|
| Service | Port | Protocol |
|
||
|
|
|---------|------|----------|
|
||
|
|
| Kafka | 9092 | TCP |
|
||
|
|
| Debezium Connect | 8083 | HTTP |
|
||
|
|
| Spark UI | 8080 | HTTP |
|
||
|
|
| Trino | 8089 | HTTP |
|
||
|
|
| PostgreSQL | 5432 | TCP |
|
||
|
|
| ObjectScale S3 | 9020 | HTTP |
|
||
|
|
| ObjectScale UI | 443 | HTTPS |
|
||
|
|
| Homepage | 80 | HTTP |
|
||
|
|
|
||
|
|
## SSH mesh
|
||
|
|
|
||
|
|
All lab VMs: `/root/.ssh/atc_cluster` — see [ssh-mesh.md](ssh-mesh.md).
|
||
|
|
|
||
|
|
ObjectScale uses `admin@` for initial bootstrap; `root@` after key install.
|
||
|
|
|
||
|
|
## Firewall notes
|
||
|
|
|
||
|
|
- Lab assumes flat L2/L3 trust within `10.0.10/20/21.x`.
|
||
|
|
- ObjectScale `management_clients: 0.0.0.0/0` in deploy.yml — tighten for production.
|
||
|
|
- Proxmox API `:8006` reachable from docker01 for homepage widget.
