Docker Cron Monitoring

Quick Setup

Create a free CronHook check, copy your ping URL, and add it to your Docker setup:

# Dockerfile
FROM alpine:latest
RUN echo "*/5 * * * * /app/backup.sh && wget -qO- https://cronhook.site/ping/YOUR_CHECK_ID" | crontab -
CMD ["crond", "-f"]

How It Works

1. Create a check — Give it a name, set the expected period (e.g. 5 minutes).
2. Add the ping — Add the curl request (or HTTP call) at the end of your task.
3. Get alerted — If the ping doesn't arrive on time, CronHook alerts you via Email, Slack, or Discord.
