Using pup with Docker

The example at /docs/src/examples/docker runs a Deno script periodically with Pup in the official Deno docker imag.

Files

Dockerfile - Sets up a container based on denoland/deno:debian-1.31.1, installs Pup, and copies this directory content to /app/
pup.jsonc - Pup configuration, sets up task.ts to run at cron schedule 0/5 * * * * * (every fifth second).
task.ts - The actual script to run. Prints "Task running" to console and exits.

Building and running

cd to /docs/src/examples/docker directory.

Build image

Run docker build . --tag=pup-docker-demo

Run image

Run docker run -d --name="pup-demo" pup-docker-demo

Check logs to verify everything is working
