module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Configuration

For full parameter reference see the official documentation for the installed version. This module doesn't attempt to validate registry config specification. Merged configuration is serialized to JSON which will be syntactically correct but the config should be validated against distSpecVersion using e.g. zot verify /etc/zot/config.json.

Change storage directory:

zot::data_dir: /srv/zot

Change log directory:

zot::log_dir: /srv/log

In order to bind the zot service on ports < 1024, you'll need either root priviledges or configure bind capabilities, e.g. using file_capability

file_capability::file_capabilities:
  "/usr/bin/zot-%{lookup('zot::version')}":
    ensure: present
    capability: 'cap_net_bind_service=eip'

All Puppet variables are documented in REFERENCE.md.
