Some checks failed
continuous-integration/drone/push Build is failing
Patch nix/modules/swarm.nix to create the `proxy` overlay with --subnet 10.10.0.0/16 (~65k VIPs, 258× headroom over the exhausted /24). Live host survey confirms 10.10.0.0/16 is clear of all existing Docker networks (ingress 10.0.0.0/24, existing per-stack overlays 10.0.1-4.0/24, host routes). Exact maintenance procedure in STATUS-pvfix.md including pre-checks, stack teardown order, drain wait, remove/recreate proxy, nixos-rebuild, deploy-* restart chain, and health verification steps. Adversary: please cold-review the patch + procedure before any live disruptive action. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# 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.
