Webcron Management

Webcron management is an easy-to-use interface to manage cronjobs running on a publicly available http-location.

Building

Requirements for build-server

php <= 8.1 (incl composer <= 2, ext-pcntl, ext-openssl, ext-intl)
NodeJS <= 16.0 (incl. npm <= 8)

Building

Please run following command on the build server

$ composer install --no-dev --optimize-autoloader
$ npm install
$ npm run build
$ rm -rf node_modules # Node modules are only required for building

Installation

Requirements

php <= 8.1
- ext-openssl
- ext-intl
- ext-pcntl (highly recommended)
MariaDB
SSH-access to the server
Ability to change the webroot directory
Ability to run a script as daemon (eg. supervisor or systemd units)

Installation

Create a build yourself or download the build from the releases page
Upload the build to the webserver.
Set up your webhosting to use the /public directory as web root
Create the .env file by copying .env.sample to .env and change the values
Run php bin/console doctrine:migrations:migrate to create or migrate the database
Create a first user by running php bin/console webcron:user add
Set up the daemon script using systemd, supervisord or similar system

If this is not possible running the daemon using a cronjob is still possible using below gist (Not recommended)

0 * * * * cd /path/to/webcron/ && php webcron daemon --time-limit=3600 > /dev/null 1&>2

Upgrading

Requirements

Same requirements and deploying

Procedure

Remove all files except .env from the webserver
Upload the new build to the webserver
Run php bin/console doctrine:migrations:migrate to migrate the database

Common pitfalls

I can't do an automatic system upgrade!

Doing a system upgrade requires sudo which has a certain number security measurements. To enable running anything with sudo (eg. sudo apt dist-upgrade -y) the user needs to be able to run sudo without tty and password.

TL;DR
