Explorer maintenance cron
Automated jobs to prevent 502s, disk full, and nginx downtime on VMID 5000 (explorer.d-bis.org).
Install (one-time)
From the explorer-monorepo directory:
On Proxmox host that has VMID 5000:
bash scripts/cron/install-explorer-cron.sh
From your machine (SSH to node):
EXPLORER_VM_HOST=root@192.168.11.12 bash scripts/cron/install-explorer-cron.sh
What gets installed (inside VMID 5000)
| Schedule | Job | Purpose |
|---|---|---|
| Every 5 min | /usr/local/bin/explorer-maintain.sh |
If API ≠ 200: restart Blockscout or start from docker-compose. If nginx inactive: start nginx. |
| Daily 03:15 | RUN_PRUNE=1 /usr/local/bin/explorer-maintain.sh |
If disk usage ≥ 90%: safe prune (unused images + build cache only; no container prune). |
Log file: /var/log/explorer-maintain.log (inside the VM).
