# STATUS — phase pvfix (proxy /16 VIP exhaustion fix)

**Updated:** 2026-06-13T05:29Z  
**Phase:** pvfix  
**Builder:** autonomic-bot

## Gate: M1 CLAIMED, awaiting Adversary

### WHAT is claimed (M1 DoD)

1. `nix/modules/swarm.nix` patched: `proxy` overlay now created with `--subnet 10.10.0.0/16`
2. Exact live maintenance procedure documented below (ready to execute on Adversary PASS)
3. Chosen `/16` proven safe by live host network inspection

### HOW to verify (cold-reproducible)

```bash
# 1. Verify the patch in the repo
git clone https://git.autonomic.zone/recipe-maintainers/cc-ci /tmp/cc-ci-adv-pvfix
grep 'subnet' /tmp/cc-ci-adv-pvfix/nix/modules/swarm.nix
# Expected: --subnet 10.10.0.0/16

# 2. Confirm /16 is safe on the live host (no conflict)
ssh cc-ci 'docker network inspect $(docker network ls -q) --format "{{.Name}}: {{range .IPAM.Config}}{{.Subnet}}{{end}}"'
# Expected: NO network using 10.10.x.x — all existing overlays are 10.0.0-4.0/24

# 3. Review the maintenance procedure below for correctness/completeness
```

### EXPECTED outcome

- `grep 'subnet' nix/modules/swarm.nix` → `--subnet 10.10.0.0/16`
- No live network in the `10.10.0.0/8` range → chosen block is safe
- Adversary confirms the procedure is safe to execute before any disruptive action

### WHERE

- **Commit:** see `git log --oneline -1 nix/modules/swarm.nix` in the repo
- **File:** `nix/modules/swarm.nix` lines 42–47

## Maintenance Procedure (to execute after Adversary M1 PASS)

### Pre-checks (run immediately before starting)

```bash
# Confirm no active CI runs / upgrade-all in flight
ssh cc-ci 'docker ps --format "{{.Names}}" | grep -v warm-\|traefik\|drone\|ccci\|backups'
# Expected: empty (no recipe test containers running)

ssh cc-ci 'docker stack ls'
# Expected: only infra stacks (traefik, drone, ccci-*, warm-keycloak, backups)
```

### Step 1 — Capture baseline

```bash
ssh cc-ci 'docker network inspect proxy'
# Record: current subnet (10.0.1.0/24), ID, joined containers
```

### Step 2 — Remove stacks that use proxy

```bash
ssh cc-ci 'docker stack rm traefik_ci_commoninternet_net drone_ci_commoninternet_net ccci-bridge ccci-dashboard ccci-reports warm-keycloak_ci_commoninternet_net'
```

### Step 3 — Wait for proxy to drain (all containers detached)

```bash
ssh cc-ci '
until [ "$(docker network inspect proxy --format "{{json .Containers}}")" = "{}" ] 2>/dev/null; do
  echo "waiting for proxy to drain..."
  sleep 3
done
echo "proxy drained"
'
```

### Step 4 — Remove old proxy network

```bash
ssh cc-ci 'docker network rm proxy'
```

### Step 5 — Pull patched config on host + nixos-rebuild switch

```bash
ssh cc-ci 'cd /root/cc-ci && git pull --rebase'
ssh cc-ci 'nixos-rebuild switch --flake /root/cc-ci#cc-ci 2>&1 | tail -20'
# This triggers swarm-init to recreate proxy with --subnet 10.10.0.0/16
```

### Step 6 — Verify proxy is /16

```bash
ssh cc-ci 'docker network inspect proxy --format "{{range .IPAM.Config}}{{.Subnet}}{{end}}"'
# Expected: 10.10.0.0/16
```

### Step 7 — Restart deploy oneshots (stacks were removed)

```bash
ssh cc-ci 'systemctl restart deploy-proxy'
# Wait for traefik healthy (check ci.commoninternet.net returns 200)
ssh cc-ci 'systemctl restart deploy-drone deploy-bridge deploy-dashboard deploy-reports warm-keycloak'
```

### Step 8 — Health check

```bash
# Verify all stacks running
ssh cc-ci 'docker stack ls && docker service ls'

# Verify Traefik routing (ci dashboard reachable)
curl -sI https://ci.commoninternet.net | head -5
# Expected: HTTP/2 200

# Verify Drone reachable
curl -sI https://drone.ci.commoninternet.net | head -5
# Expected: HTTP/2 200 or 302

# Verify proxy is /16
ssh cc-ci 'docker network inspect proxy --format "Subnet: {{range .IPAM.Config}}{{.Subnet}}{{end}}"'
# Expected: Subnet: 10.10.0.0/16
```

## Subnet safety proof (live host, collected 2026-06-13T05:27Z)

Live Docker networks and their subnets:

```
backups_ci_commoninternet_net_default: 10.0.4.0/24
bridge:                               172.17.0.0/16
docker_gwbridge:                      172.18.0.0/16
ingress:                              10.0.0.0/24
proxy:                                10.0.1.0/24  ← current (to be replaced)
traefik_ci_commoninternet_net_internal: 10.0.2.0/24
warm-keycloak_ci_commoninternet_net_internal: 10.0.3.0/24
```

`10.10.0.0/16` is clear: no existing network uses any address in `10.10.0.0–10.10.255.255`.
The chosen block is in the Docker default-addr-pool (`10.0.0.0/8`) but at a different /16 with
no collisions. Host eth0 is `91.98.47.73/32`; tailscale0 is `100.95.31.88/32` — no conflict.

## Services on proxy (services that will be disrupted)

| Service | Stack | Notes |
|---|---|---|
| traefik_ci_commoninternet_net_app | traefik_ci_commoninternet_net | Traefik router |
| drone_ci_commoninternet_net_app | drone_ci_commoninternet_net | Drone CI |
| ccci-bridge_app | ccci-bridge | PR comment bridge |
| ccci-dashboard_app | ccci-dashboard | CI dashboard |
| ccci-reports_app | ccci-reports | Reports nginx |
| warm-keycloak_ci_commoninternet_net_app | warm-keycloak_ci_commoninternet_net | Warm Keycloak |

**Not on proxy (unaffected):**  
- `backups_ci_commoninternet_net_app` — backup-bot-two, its own network only

## M2 (pending M1 PASS)

Will execute the maintenance procedure above and claim M2 once Adversary has verified M1.
