In case of linting errors, print stdout and stderr (if present)
at the ERROR level if users set LOG_LEVEL to NOTICE to avoid
failures without any explanation.
Terrascan runs initialization anyway when scanning files, so there's no
point in running it at build time. Also, this works around a Terrascan
bug that caused it to fail its initialization if $HOME/.terrascan
directory is not present. This happens on GitHub Actions because it
configures a $HOME directory that is different from ours.
- Super-linter uses the LOG_LEVEL variable to let the user
configure the desired log level. Checkov and Renovate use a variable
with the same name for the same purpose, but accept a
different set of values, and exit with an error if it gets an unknown
value for that variable.
- Refactor the VERBOSE log level to the more commonly used INFO.
Configuration validation will warn users if they use VERBOSE and
instruct them to use INFO instead. This is not a breaking change
because super-linter falls back on INFO if VERBOSE is set.
- Remove the TRACE log level because we rarely used it. As with VERBOSE,
configuration validation will warn the user. Fall back to DEBUG if the
user configured LOG_LEVEL to VERBOSE.
