2. Run DeLiC

By default, DeLiC tries to read the config file at ./config.yml.

docker run -v /path/to/config.yml:/config.yml:ro,z jenswbe/dead-link-checker

3. CLI arguments

-c, --config    Location of the config file
    --json      Print all site reports as JSON to stdout
    --now       Overrides cron and forces an immediate check
-v, --verbose   Enable verbose output
